  • Are Key Fobs Waterproof? A Comprehensive Guide to Keeping Your Key Fob Safe
Post Name
21.01.2025

In an era of advanced automotive technology, key fobs have become an essential part of modern driving. From unlocking doors to starting engines remotely, these small yet powerful devices are a marvel of convenience. However, one question often looms in the minds of car owners: are key fobs waterproof? With water being a common hazard in everyday life, understanding the limitations and care requirements of your key fob is crucial.

Understanding Key Fob Technology

Key fobs are more than just electronic keys; they are compact computers that communicate with your car. Using radio frequency (RF) technology, they transmit encrypted signals to your vehicle, enabling features like remote locking, engine start, and even personalized settings. This intricate technology is housed in a small casing that protects the internal components.

While key fobs are designed to endure daily wear and tear, their resilience to water varies. Some models offer water resistance, but this is not synonymous with being fully waterproof. The degree of water resistance depends on the design and build quality of the key fob, which can differ significantly between manufacturers and models.

Are Key Fobs Waterproof or Water-Resistant?

The terms “waterproof” and “water-resistant” are often used interchangeably, but they have distinct meanings. Waterproof indicates that a device can be submerged in water without damage, while water-resistant means it can withstand splashes or brief exposure to water but not submersion.

Most key fobs fall into the latter category. For example, some car manufacturers claim their key fobs can handle minor splashes or light rain. However, prolonged exposure to water or immersion—such as dropping your fob into a pool—can damage the electronic components and render the device unusable.

Global Standards and Variability

Globally, there is no universal standard governing the water resistance of key fobs. Manufacturers often follow internal guidelines or industry best practices. In some regions, automakers have started offering key fobs with improved water resistance as a response to customer demands for greater durability. For instance, luxury brands like BMW and Mercedes-Benz have introduced models with enhanced protection, but even these devices are not guaranteed to survive complete immersion.

Comparatively, in markets where cost efficiency is prioritized, such as in certain developing countries, key fobs may lack advanced water-resistant features. This variability underscores the importance of checking the specifications of your specific key fob model.

What to Do If Your Key Fob Gets Wet

Accidents happen, and it’s not uncommon for key fobs to encounter water. If your key fob gets wet, quick action can often prevent permanent damage.

First, remove the key fob from water immediately and dry it thoroughly with a soft cloth. If possible, open the casing to allow air circulation and dry the internal components. Avoid using heat sources such as hair dryers, as excessive heat can warp the plastic casing or damage the sensitive electronics.

In cases of significant water exposure, placing the key fob in a container of uncooked rice or silica gel packets can help absorb moisture. However, this is not guaranteed to save a severely water-damaged key fob. If the device does not work after drying, contacting a professional locksmith or dealership for repair or replacement is the best course of action.

Tips for Protecting Your Key Fob

To minimize the risk of water damage, there are several precautions you can take:

  1. Use a protective case or cover designed specifically for key fobs. These accessories provide an added layer of protection against moisture and physical impacts.
  2. Avoid placing your key fob in pockets or bags where it may come into contact with liquids, such as water bottles or spilled drinks.
  3. Store your key fob in a designated dry area when not in use, particularly in environments where water exposure is likely, such as beaches or pools.

The Future of Waterproof Key Fobs

As technology advances, so does the potential for more robust key fobs. Automotive manufacturers are exploring the use of advanced materials and sealing techniques to create truly waterproof devices. Additionally, the rise of smartphone-based digital keys may eventually render physical key fobs obsolete, eliminating concerns about water damage altogether.

Internationally, innovations in waterproofing technology are being driven by consumer demand and environmental considerations. For example, in regions with high humidity or frequent rainfall, automakers are under pressure to offer more durable solutions. As a result, future key fobs may combine water resistance with other features, such as solar charging or biometric security.

Navigating the Realities of Key Fob Care

Key fobs are indispensable in modern driving, but they are not invincible. While some offer limited water resistance, the majority are vulnerable to prolonged exposure or immersion. Understanding these limitations and taking proactive measures to protect your key fob can save you time, money, and frustration.

As technology evolves, the prospect of waterproof or entirely digital keys becomes more realistic. For now, car owners should familiarize themselves with the specifications of their key fobs and follow best practices for care. Whether you’re navigating a sudden downpour or an accidental spill, a little knowledge and preparation can go a long way in safeguarding your key fob and ensuring uninterrupted access to your vehicle.

Lost Your Witter, GDW, Thule (Brink) or TowTrust Towbar Key? Here's What to Do.

Lost Your Witter, GDW, Thule (Brink) or TowTrust Towbar Key? Here's What to Do.

Lost your towbar key right before a holiday or towing trip? You’re not alone. Detachable towbar keys are typically used only occasionally – often just before a caravan holiday or when you need to tow – which means they spend most of the year tucked away. It’s all too easy for that lost towbar key to go missing between uses. The good news is that if your key has an ACS-series code (ACS01–ACS10) engraved on it, you can order a precise replacement online in minutes and avoid throwing a wrench in your travel plans. What are ACS towbar keys? The ACS-series keys are a common type of detachable towbar key numbered ACS01 through ACS10 (for reference: ACS01, ACS02, ACS03, ACS04, ACS05, ACS06, ACS07, ACS08, ACS09, ACS10). These keys fit a specific locking system used by multiple towbar manufacturers. In fact, an ACS towbar key could belong to a detachable hitch from ACS itself or from popular brands like Witter, GDW, Thule (Brink) or TowTrust – all of whom use the same ACS lock design. What matters is the code stamped on your key or lock. If it falls in the ACS01–ACS10 range, that code is all you need to get a new key cut and shipped to you. Check Your Key Code (ACS01–ACS10) Before you panic, inspect your towbar’s lock (or any remaining key) for a small engraved code. Most detachable towbar locks have the key number stamped either on the face of the lock barrel or on the original key itself. For the ACS series, this code will start with “ACS” followed by a two-digit number – for example, ACS04 or ACS09. If you see a code in the format ACS## and especially if it’s between ACS01 and ACS10, you’re in luck. That means your towbar uses the ACS key system, and a towbar key ACS01–ACS10 replacement can be ordered without changing the lock. Why is the key code important? This unique code is what key cutting services use to create an exact match for your lock. No original key is required – the code itself tells the cutter how to shape the new key. As long as the code is clearly visible (and within the supported range), you won’t need to replace the entire towbar lock or mechanism. Just supply the code and a new key can be made to fit perfectly, as if it were the original. Tip: Wipe the lock face clean or use a flashlight if needed – dirt and road grime can obscure the tiny engraving. On some keys the code might be on the plastic head or metal shaft of the key. Look for “ACS” followed by numbers. Compatible Towbar Brands for ACS Keys One big advantage of the ACS lock system is its cross-compatibility. These key codes ACS01–ACS10 aren’t limited to a single towbar brand – they’re used across several major manufacturers of detachable towbars. If you have a detachable towbar from any of the following brands, there’s a good chance it uses an ACS-series key: ACS (A50-X) – ACS is the original supplier of this locking system (often referred to as the A50-X class detachable). Keys for ACS detachable towballs will have codes ACS01–ACS10. Brink / Thule – Thule’s towing division (now Brink) uses ACS keys for many of its detachable hitches. If you have a Thule or Brink detachable towbar, check for an ACS code on the lock. (Brink/Thule locks with codes like 1D## or 2D## are a different series – but ACS## codes are common on earlier Thule/Brink models.) Witter – A very popular towbar brand, Witter uses the ACS system on their detachable swan-neck towbars. A Witter detachable with an ACS key will have “ACS” on the key or lock face. Witter towbar key replacements are readily available by code. GDW – This European towbar manufacturer also uses ACS-series keys for many detachables. If you need a GDW towbar replacement key, the process is the same: find the ACS## code and order a matching key. Tow-Trust – TowTrust (Tow-Trust) towbars, often sold in the UK and EU, utilize ACS keys as well. Tow-Trust detachable models with ACS locks will have codes ACS01–ACS10 on the keys. Other brands like PCT Automotive or Towsure have also been known to use ACS locks in some of their detachable towbar systems. The key point is that multiple brands share this ACS key design. So whether your hitch is labeled Witter, Thule, Brink, GDW, or TowTrust, if the key code starts with ACS, you can get the correct replacement towbar key by that code. This compatibility makes it easier to find spares, since one good supplier can cover many brands under the ACS series. Quick Reference: ACS Key Codes and Brands For easy identification, here’s a summary of which detachable towbars use the ACS01–ACS10 key range: Towbar Brand Detachable Key Code Series Example Key Code ACS (A50-X system) ACS01 – ACS10 ACS07 (on key/lock) Brink (Thule Towbars) ACS01 – ACS10 ACS05 Witter ACS01 – ACS10 ACS03 GDW ACS01 – ACS10 ACS09 Tow-Trust ACS01 – ACS10 ACS02 If your towbar brand is listed above and you see an “ACS*” code on the lock, you can order a new key by that code. In the example codes, the number can be any from 01 to 10. How to Order a Replacement ACS Towbar Key Online One of the great things about these keys is how simple it is to get a replacement. You don’t need to visit a dealership or locksmith in person; you can order an ACS towbar key online and have it cut to code and delivered to your door. Here’s how to do it: 1. Locate the ACS key code – As mentioned, find the engraved code on your existing key or the towbar lock barrel (e.g. ACS08). Double-check that it’s in the ACS01–ACS10 range. 2. Visit a replacement key website – Go to a trusted online key supplier that offers keys cut to code. For example, you can order from a specialized service like Mr. Key. They have a product page specifically for spare keys for ACS A50-X / Brink / Thule towbars (codes ACS01–ACS10) – this is where you’ll enter your code to get the correct key. 3. Select your key code – On the product page, choose your exact code (say, ACS04 or ACS09) from the dropdown or list. 4. Place your order – Add the replacement key to your cart and check out. These keys are very affordable (usually only a few dollars or euros each), and you can often choose expedited shipping if you’re in a hurry. 5. Receive and test the key – Shipping is typically quick (a few days within Europe). Once it arrives, test the replacement towbar key in your detachable towbar’s lock. It should turn smoothly and unlock the mechanism just like the original. Problem solved. Product Link: https://mr-key.com/product/spare-key-for-acs-a50-x-brink-thule-towbar-codes-acs01-acs10 You can order the correct replacement key here: Spare Key for ACS A50-X / Brink / Thule Towbar – Codes ACS01–ACS10. Simply select your code from ACS01 up to ACS10 and choose the key with the matching number. The new key will be cut to that code and sent to you ready to use. Ordering online is not only convenient but also ensures you get the precise key you need. These keys are cut by code using professional tools, so you don’t have to worry about tracing an old key or guesswork. As long as the code you provide is correct, the new key will fit perfectly or you can get your money back. Make a Spare Key Now to Avoid Future Stress Once you have your new key in hand (or if you still have your original), it’s time to think ahead. Don’t wait until you’ve lost the only key to take action. Cutting a spare key while you still have a working one is quick and inexpensive, and it can save you a lot of trouble down the road. Here are some benefits of having a spare towbar key: No more last-minute panic: If one key goes missing, you’ll have a backup ready. This means no frantic searches the night before your trip and no postponed travel plans due to a missing key. Avoid costly lock replacements: Losing the only towbar key can be expensive – you might be forced to drill out the lock or replace the entire detachable neck mechanism. A spare key (which typically costs under £10) is far cheaper than a new lock or towbar. Keep your holiday on track: A Thule towbar spare key or Witter towbar spare key tucked in your glove box ensures that a lost key won’t derail your caravan holiday or trailer rental schedule. You can continue towing without delay. Fast & affordable peace of mind: Ordering an extra key by code is both fast and affordable. Many drivers are surprised at how easy it is – often it’s just a couple of clicks online and a short wait for delivery. It’s a small investment for the security of knowing you’re covered. Consider ordering two keys when you get your replacement. Many suppliers even offer a deal on a second key (or include a pair by default), so you can keep one spare at home and one in the vehicle. Having multiple keys means you’re highly unlikely to ever be locked out of your own towbar again. Losing your towbar key can be a frustrating experience, especially when it happens right before you need to use it. But if your detachable towbar uses the ACS lock system (codes ACS01–ACS10), solving the problem is straightforward. With a visible ACS key code and a reliable online key-cutting service, you can quickly get a new replacement towbar key cut to code and delivered. There’s no need for costly new locks or last-minute cancellations of your towing plans. Don’t let a lost towbar key ruin your trip. Take a moment to check your towbar for an ACS code. If it’s there, you can have a new key on the way in no time. And even if your current key is in hand, think ahead – get a spare made now to save yourself stress later. With fast online ordering and prices that won’t break the bank, getting an ACS towbar key replacement is the easiest way to ensure you’re never stuck without the key to your adventures. Safe towing.

How to Take the Perfect Photo of Your Key for Easy Replacement

When you need a replacement key , taking a clear, detailed photo of your key can make the process much faster and more accurate. A high-quality image helps key makers understand the exact specifications, cuts, and dimensions of your key, which is especially important if you don’t have a spare. In this guide, we’ll walk you through the best practices for photographing your key so you can get an accurate replacement with ease. Why a Clear Key Photo Matters Photographing a key might sound simple, but it requires a bit of attention to detail. A well-taken photo captures the key’s grooves and unique cuts clearly, helping the key cutter replicate the exact pattern. Saves Time : A high-quality photo reduces the need for multiple attempts to cut a new key . Ensures Accuracy : Clear images help capture specific details, leading to a more precise fit. Convenient Process : With just a smartphone and a few tips, you can photograph your key from home without needing special equipment. Essential Tools for Photographing Your Key To take a clear photo of your key, you don’t need much beyond a few household items. Here’s what you’ll need: Smartphone or Camera : A phone camera is usually sufficient, but a standard digital camera works well too. Plain Background : Choose a neutral, solid-colored background like a piece of white paper or a smooth table surface. Good Lighting : Natural daylight or a bright room light helps capture details without shadows. Small Object for Elevation : A coin or similar item can lift the key slightly, making it easier to photograph. Step-by-Step Guide to Taking the Perfect Key Photo Follow these steps to take a photo that ensures clarity and accuracy for key replacement. 1. Set Up the Background Place a piece of plain white paper or another smooth, light-colored surface under your key. The solid color helps the details of the key stand out without any visual distractions. Tip : Avoid backgrounds with patterns or textures, as these can obscure the key’s features. 2. Position the Key Correctly Lay the key flat on the background, with the grooves and cuts facing up. The key should be positioned horizontally to allow a clear view of all its details. Side Profile : Make sure to capture the side profile that shows the cuts and grooves. Elevate Slightly : Place a coin or small object under one end of the key to angle it slightly toward the camera. This can help reduce shadows and improve focus on the cuts. 3. Adjust Lighting Good lighting is essential for capturing details. If possible, photograph your key in natural daylight near a window or use a well-lit room. Avoid Shadows : Ensure that no shadows fall across the key, as they can obscure details.

Focus and Zoom Make sure your camera or smartphone is focused directly on the key. You may need to tap the screen to bring it into sharp focus. Zoom in Carefully : If you’re using a smartphone, zoom in slightly to capture the details, but avoid over-zooming, which can blur the image. Test Multiple Angles : Sometimes a slight adjustment in angle can capture the cuts more effectively, so take a few shots from slightly different perspectives. 5. Capture Multiple Photos It’s always a good idea to take several photos to ensure you have the best one. Try different angles and lighting adjustments to capture as many details as possible. Close-Up of the Grooves : Take one close-up image focusing on the cuts and grooves of the key. Overall Image : Include one full-length photo that shows the entire key from end to end. Try Different Angles : Slightly tilt the key or move the camera to see which angle best captures the detail of the cuts. Common Mistakes to Avoid When Photographing Your Key To get the best results, steer clear of these common issues that can impact the quality of your key photo: Blurry Images : If your hand shakes, use a small tripod or prop your phone on a stable surface. Poor Lighting : Avoid taking photos in dim rooms; use bright light to ensure the key is clearly visible. Obstructed Details : Make sure the entire length of the key is visible, without any part being cut off or covered. Tips for Ensuring a Smooth Replacement Process Once you have a clear photo of your key, there are a few final steps to make the replacement process as efficient as possible. Check the Photos : Look over your photos before sending them to ensure that they’re clear and detailed. Label the Key : If you’re photographing multiple keys, label each one in the image or add a note to avoid confusion. Include Measurements : If possible, add the measurements of the key’s length and width in your notes for added accuracy. A clear, detailed photo of your key can save you time and effort when seeking a replacement. By following these simple steps, you’ll provide all the necessary details to ensure your new key is an accurate match. Remember, good lighting, focus, and capturing all the unique cuts are essential to achieving the best results. With these guidelines, you’re set to take a photo that will make your key replacement process smooth and hassle-free.

Do Car Keys Have GPS? What You Need to Know About Key Tracking

Do Car Keys Have GPS? What You Need to Know About Key Tracking

In an age where smartphones can locate us with pinpoint accuracy and lost luggage can be tracked halfway around the world, it’s easy to assume car keys are just as smart. But for many frustrated drivers, losing a car key feels like sending it into a black hole. The lack of a clear way to find them often leads to stress, wasted time, and sometimes costly replacements. So here’s the big question: Do car keys have GPS, and can they be tracked like other smart devices? This article explains the technology behind key tracking, compares GPS with Bluetooth, and offers practical ways to find lost keys in a connected world. The Truth About GPS in Car Keys While GPS technology has become common in many consumer devices, the vast majority of car keys do not include built-in GPS. Even the most modern remote key fobs, which allow for keyless entry and push-button start, generally lack the components necessary for GPS functionality. These components include a satellite GPS receiver, a data transmission module, and a sustainable power source—none of which are typically found in a key fob. The design of a car key prioritizes compactness, cost-efficiency, and low energy usage. Adding GPS would not only increase manufacturing costs but also introduce battery life challenges. That’s why most manufacturers have opted against including GPS tracking in car keys. GPS requires constant power and data transmission — something a small coin cell battery in a typical key fob can’t support." – Marcus Lee, Automotive Tech Analyst How Can Car Keys Be Tracked? Although your keys may not have GPS, there are other technologies that make it possible to track or locate them when they’re lost. These include Bluetooth trackers, crowdsourced networks, and GPS systems that track the vehicle instead of the key itself. 1. Bluetooth Trackers (Apple AirTag, Tile, Chipolo) These small, attachable gadgets can be added to your keychain and linked to a mobile app. They rely on Bluetooth to provide location data when within a certain range. If your keys are somewhere nearby—like in your home or office—these trackers can play a sound or show you their last known position on a map. The range is generally up to 120 meters (400 feet), and battery life can last up to a year, making them a practical, low-maintenance option for most users. 2. Crowdsourced Networks (Find My, Tile Network) If your Bluetooth tracker is out of range, some brands offer a smart workaround. Apple’s AirTag, for instance, uses the “Find My” network, which consists of millions of iPhones around the world. If someone with an Apple device passes near your lost keys, the location is anonymously and securely sent to your phone. This creates a global, decentralized tracking system that mimics GPS functionality without requiring satellites or cellular connections. 3. Car GPS Systems (Vehicle Only, Not the Key) Some high-end cars offer integrated GPS systems, but these track the vehicle, not the keys. Brands like Tesla, BMW, and Mercedes-Benz allow owners to locate their car through mobile apps. If your keys are left inside the car, you may be able to find them by locating the vehicle. However, once the keys are removed, they cannot be tracked unless equipped with a separate Bluetooth tracker. GPS vs Bluetooth: What’s the Difference? To better understand why GPS isn’t commonly included in car keys, it’s useful to compare the two technologies: GPS provides global, real-time tracking with high precision, but it’s power-intensive and costly. Bluetooth, while more limited in range, is ideal for small items and short distances, offering a cost-effective solution for everyday use. Global Perspectives on Key Tracking Around the world, the adoption of key tracking technologies differs based on privacy laws, tech infrastructure, and consumer behavior. In Japan and South Korea, smart home and car integration are advanced, yet GPS-enabled keys are still not the norm. In many parts of Europe, particularly in countries like Germany, Bluetooth solutions are favored due to strict data privacy regulations. In contrast, the U.S. market has embraced personal tracking devices like Apple AirTag and Tile, making them increasingly common accessories. These differences highlight how technology adoption often reflects broader cultural and legal norms, as well as the balance between convenience and privacy. Smart Tips to Keep Track of Your Keys Whether your keys have advanced tech or not, you can take simple steps to avoid losing them. Attaching a Bluetooth tracker is a great first line of defense. Keeping your keys in a consistent, designated place at home reduces the chances of misplacement. Many tracking apps also offer “left behind” alerts, which notify you if you leave your keys behind when moving out of range. It's also smart to keep a spare key somewhere safe and consider going keyless if your next car allows it. Implementing a few of these habits can save you time, frustration, and the cost of replacing a lost key. The Future of Key Tracking While car keys may not have built-in GPS, technology continues to evolve with practical alternatives. Bluetooth trackers, supported by app alerts and community networks, already provide effective ways to find lost keys. As innovation progresses, we can expect even more seamless solutions, such as Ultra Wideband (UWB) technology and Internet of Things (IoT) integrations, to become mainstream. As our tools become smarter, so must the way we use and manage them. With a little foresight and the right accessories, you'll never lose track of your keys again.

How to Install a Hydrogel Navigation Screen Protector

Nowadays car interiors rely heavily on touchscreens. Whether you drive a BMW 3 Series , VW Golf , Audi A4 , Mercedes A-Class , Peugeot 3008 , or Skoda Octavia , your infotainment display is the centre of navigation, settings, entertainment and safety features. But these screens are also fragile—prone to scratches , fingerprints , micro-abrasions , and glare . A hydrogel navigation screen protector is one of the best ways to protect your car touchscreen without affecting clarity or touch sensitivity. This guide shows you exactly how to install a hydrogel protector , step by step, with expert tips, mistakes to avoid, and a few insider tricks that most guides miss. What Is a Hydrogel Screen Protector? Hydrogel is a soft, self-healing, flexible material used widely in phone protection and now increasingly in automotive displays. Unlike tempered glass, it adapts to curved edges and eliminates small bubbles over time. For more technical background, you can read the scientific definition on hydrogels Hydrogel is ideal for infotainment screen protection because it: Reduces glare Absorbs micro-scratches Maintains full touch sensitivity Adapts to curved and angled car screens Self-heals small marks over 24–48 hours It’s especially useful for European cars where screens are large and glossy, such as: Mercedes MBUX screens (A-Class, C-Class, GLC) Volkswagen MIB systems (Golf, Passat, Tiguan) BMW iDrive displays (3 Series, X1, X3) Audi MMI touchscreens (A4, A3, Q5) Peugeot i-Cockpit models Renault Clio, Captur, Megane Skoda Octavia, Superb, Scala Curious which specific models benefit the most from hydrogel protection? Check out our full guide on which cars benefit most from hydrogel navigation protection . Before You Start: Essential Preparation Installing a hydrogel protector takes only a few minutes, but the preparation stage determines whether the final result looks factory-perfect .
