Post Name

Regular lock maintenance is essential to prevent key jamming or lock failure. Proper lubrication reduces wear and tear, ensures smooth operation, and extends the lifespan of your locks. A well-lubricated lock decreases the risk of your key getting stuck or breaking inside the lock—an inconvenient and costly problem. At MR-KEY, we understand the importance of well-maintained locks and want to help you keep yours in top condition.

 

How Often Should You Lubricate Your Locks?

 

For most locks, lubricating them every three to six months is sufficient. However, locks exposed to extreme weather conditions—such as those on towbars, roof racks, or outdoor gates—require more frequent maintenance. Rain, dust, and freezing temperatures can cause internal components to stick, making it difficult to insert or turn the key. If you notice resistance when using a lock, it’s time for lubrication.

 

What Lubricant Should You Use for Locks?

 

Choosing the right lubricant is crucial for long-term lock performance. Here are the best options:

• Teflon-based (PTFE) spray – Forms a protective film inside the lock, reducing friction and repelling dust buildup.

• Dry silicone spray – Excellent for outdoor locks as it resists moisture without attracting dirt.

• WD-40 Specialist Dry PTFE or White Lithium Grease – Unlike regular WD-40, these provide long-lasting lubrication and protection against corrosion.

• Graphite powder – A great choice for older locks but should not be used if there’s oil residue inside the lock.

 

While WD-40 Multi-Use is a quick fix for stuck locks, it is primarily a cleaner rather than a long-term lubricant. If used, follow up with a dry lubricant to prevent dirt accumulation inside the lock.

 

How to Lubricate a Lock

 

If your lock is functioning properly but feels slightly stiff, follow these steps:

1. Clean the Lock – Insert and remove the key a few times to dislodge debris, wiping it clean each time.

2. Apply the Lubricant – Insert the spray straw into the keyhole and apply two short bursts of lubricant.

3. Work the Lock – Insert and turn the key multiple times to distribute the lubricant inside.

4. Wipe Excess Lubricant – Remove any residue from the key and lock exterior to prevent dirt buildup.

 

For graphite powder, follow the manufacturer’s specific instructions, as overapplication can lead to clumping inside the lock.

 

Special Care for Towbar and Roof Rack Locks

 

Locks on towbars and roof racks are exposed to harsher conditions than typical door locks. To keep them in good shape:

• Regularly inspect them for stiffness or corrosion.

• Apply dry silicone spray or PTFE lubricant for lasting protection.

• If the lock is exposed to frequent moisture, white lithium grease offers superior water resistance.

 

Lock It in: The Key to Long-Lasting Security

 

Regular lock maintenance is a small effort that prevents big problems. By keeping your locks clean and properly lubricated—especially those exposed to the elements—you can avoid costly repairs and ensure they function smoothly for years.

How to Protect Your Car Key Fob from Relay Attacks

How to Protect Your Car Key Fob from Relay Attacks

Car theft has entered the digital age — and unfortunately, so have the thieves. As car manufacturers move toward keyless technology, a new type of threat has emerged: the relay attack. Unlike traditional break-ins, this high-tech method allows criminals to steal a vehicle without touching the keys — or even breaking a window. Imagine this: your car is parked safely outside your house. Your key fob is inside, hanging on a hook by the front door. You're fast asleep. But outside, two individuals with small electronic devices are working together. One stands near your front door, scanning for a signal from your key fob. The other waits by your car. Within seconds, your key’s signal is captured, extended, and transmitted to your car. It unlocks, starts, and drives away — and you might not notice until morning. This is not science fiction. It's called a relay attack , and it's one of the fastest-growing vehicle theft methods worldwide. Why Relay Attacks Are So Effective The key to this technique is exploiting the constant communication between your car and its fob. Most keyless entry systems are designed for convenience — you don’t even need to press a button. The car automatically detects the presence of the key fob and unlocks when you approach. This convenience is exactly what makes it vulnerable. Relay devices — which are cheap, portable, and easy to use — can mimic the signal and trick the car into thinking the key is nearby, even when it’s inside your home. Security experts have raised the alarm about this method for years, but many drivers still don’t realize how easily their vehicles can be accessed. In the UK alone, keyless car theft now accounts for more than 90% of vehicle thefts involving high-end models, according to the AA. And with the rise of online tutorials and black-market tools, the problem is growing globally. So, What Can You Do to Stay Safe? Fortunately, protecting your vehicle doesn’t require advanced tech or a huge investment — just awareness and a few smart habits. One of the most effective ways to block relay attacks is also the simplest: store your keys in a signal-blocking container . Often called a Faraday pouch or Faraday box, this lined case prevents radio signals from escaping. When your keys are stored inside, they can’t be scanned or cloned, no matter how close a thief gets to your home. Placement also matters. Many drivers leave their keys near the front door or on an entryway table — spots that are easy to access from outside. Moving your keys to the center of your home, an upper floor, or even a metal box can reduce signal exposure dramatically. Some newer key fobs allow you to manually disable the signal when it’s not in use. This feature is often hidden in the manual and rarely mentioned by dealers. Taking a moment to learn whether your key supports this — and how to activate it — can make a big difference. It’s also worth checking whether your vehicle’s software is up to date. Many automakers periodically release firmware updates that strengthen encryption or reduce signal range. In some cases, updates can even detect and block suspicious unlock attempts. And while it may seem old-fashioned, physical security still works . Devices like steering wheel locks or gear shift immobilisers can be powerful visual deterrents. Even if a thief manages to unlock your vehicle, the sight of a bulky lock inside may be enough to send them looking for an easier target. If you're looking for practical solutions beyond GPS , check out our blog: Do Car Keys Have GPS? What You Need to Know About Key Tracking . In summary, here are a few key takeaways to keep your keys and vehicle safer: Store your fob in a signal-blocking pouch or metal container Keep keys away from entry points like doors or windows Disable keyless signals if your fob supports it Update your car’s firmware regularly Use visible anti-theft devices as a deterrent Looking Ahead: Smarter Cars, Smarter Drivers Relay attacks are part of a larger trend — one where modern technology makes life more convenient, but also creates new risks. Just like we’ve learned to secure our phones and passwords, we now need to think about how we secure our vehicles. As carmakers explore more secure solutions — like Ultra Wideband (UWB) tech and biometric verification — drivers still need to take responsibility for their vehicle’s safety. The tools are already out there, and many of them cost less than a meal out. It’s not just about avoiding theft; it’s about peace of mind. So next time you get home, before tossing your keys on the hallway table, take a second to think: are they really safe there?

What to Do If You Lose Your Car Keys While Travelling?
10.11.2025

What to Do If You Lose Your Car Keys While Travelling?

1. Why this happens and why you must act fast Losing car keys while travelling is more common than you might assume. Whether it’s slipping out of a beach bag, leaving them at a café or dropping in transit, your vehicle becomes vulnerable. In addition, modern keys increasingly contain electronic transponders , chips or fobs—meaning replacement cost and complexity shoot up. When you’re away from home, both the stress and the stakes increase: you may face towing, expensive replacements or worse — being stranded. The sooner you act the less time you give for theft, theft-of-opportunity or further cost escalation. 2. Immediate steps when you realise your keys are missing a) Stay calm and retrace your steps Start by pausing. Panic hampers clear thinking. Consider the last time you remember using your keys: in the car, on unloading luggage, at hotel reception. Retrace your route slowly. As RAC advise, this step often resolves the problem without cost. b) Search systematically Check all pockets, bags, seats, coat hangers, beach bags, under cushions, in and around your car. If you’re staying somewhere temporarily, check hotel rooms, fuelling stations, parking lots. As one travel-site suggests: “Go through all your pockets… look around all surfaces in your hotel room”. c) Contact places you visited Call restaurants, cafés, shops, airport parking or hotels where you parked the vehicle. Key finders are often handed in. d) Assess risk of theft If you suspect the keys were stolen (pick-pocket, hotel burglary or unattended vehicle) you should alert local police and your insurance provider—once a key is missing, your vehicle security is compromised. e) Secure the vehicle If the vehicle is parked in an insecure location, consider moving it (if possible) or arranging towing. Leaving it locked but unattended increases theft risk. 3. How to use replacement key delivery services Replacement key delivery refers to services that cut and program a new car key and deliver it (or have it fitted) to your location—whether your holiday base, airport car park or home driveway. Steps to follow: Have vehicle details ready: make, model, year, registration number, VIN if available. Choose service: For UK and travel users, many auto-locksmiths offer mobile services that come to you. Confirm delivery logistics: Where is the vehicle parked? Will you be present when the key is delivered or fitted? If abroad, is the company able to support your location? Understand key type: Basic mechanical, transponder chip key, keyless fob—all vary in price and logistics. Check old key de-activation: A top provider will delete the lost key’s code so it cannot be used in future—critical for security. Why this is often your best path while travelling Going via your vehicle manufacturer dealer is often slower and pricier — as UK guide notes: “The quickest and least expensive way … is via an auto locksmith.” In a foreign locale, a mobile specialist or key-delivery service saves towing the vehicle and waiting for factory part shipment. 4. Hiring an emergency locksmith: what to look for When you’re locked out or stranded, an emergency locksmith (24-hour) can be your lifeline. But not all are equal. Checklist: Confirm they specialise in auto locksmith / car key replacement , not just domestic locks. Ask for credentials (affiliation with industry body). Insist on proof they will delete/pair the key to your vehicle (so lost key becomes useless). Understand travel/overseas call-out charges. Before arrival, ask for an estimate and payment process (card, cash etc.). Some holiday locales only accept cash. Stay with your vehicle in a safe public place. If you are on a remote vacation site, move to well-lit area before the locksmith arrives. Typical process: The locksmith arrives, verifies ownership (ID + logbook/V5C). They cut and/or program a key, or fix the lock/immobiliser if required. You pay for service and receive the new key — vehicle is back on the road. 5. Insurance, roadside cover and overseas travel issues Insurance/key cover Do you have lost key cover? Most UK car insurance policies don’t include lost keys as standard. You might need a premium add-on. If you claim, your no-claims bonus may be affected. Breakdown/roadside assistance Your breakdown provider (e.g., Motorway or RAC ) may offer key services, but often their vans don’t carry full key-programming equipment. So an auto locksmith still may be needed. Travelling abroad Check if your insurance/cover extends to the country you’re in. Confirm language support and local currency charges with any service you call. If you rented the car: contact the rental company immediately — they may have specific protocols for lost keys (often expensive). 6. Special cases: rental vehicles, keyless entry & fobs Rental vehicles When you lose the keys to a hire car abroad, you are likely to be liable for high fees. Rental companies will likely charge for towing and replacement, not just the locksmith. According to travel forums: “We do not offer coverage for lost keys… The replacement fee of $125 for lost key.” Call the rental agency, follow their instructions, and keep all receipts. Keyless / smart keys & modern cars Most vehicles since 2000 use transponder chips or keyless systems. Replacement these can cost several hundred pounds—UK guides show typical range from £100–£300 or more depending on brand. When you lose a keyless fob, you may need the original still in possession or need the vehicle brought to the dealer. Factor this potential delay into your travel plans. Single key left If you only have one remaining key, treat it as your last key. Get a spare made ASAP once you’re home so you’re not in the same situation again. 7. Preventative measures for your next trip Always carry a spare key at home or with a trusted person. Use a tracker (such as an AirTag or Bluetooth key-tracker) on your keyring. UK blogs suggest this simple tech helps locate lost keys. Establish a routine spot where you place your keys at the start of every journey. If you have old keys (house + car), don’t mix them during travel. Note down your vehicle details (make, model, registration, VIN) in your phone before travelling—so you’re ready if you need a replacement. For holiday car hire, take a photo of the key and keep the rental company’s emergency phone number saved. FAQ Q: What happens if I lose my only car key and I’m abroad? A: You’ll need to contact an auto locksmith or dealer who can cut and program a new key. Have vehicle details ready. Expect cost and waiting time to increase since you have no spare. Q: Can I just use a dealer to replace the key? A: Yes, but often it’s slower and more expensive . UK guides claim mobile auto locksmiths are typically faster and cheaper. Q: How long does replacement take? A: For many modern cars, the physical key can be cut quickly, but programming and blank arrival may take days. Dealers might take up to weeks. Q: Will my car insurance cover a lost key? A: Only if you have key-cover added or your insurance includes it—not standard. Check your policy. Claiming may affect your no-claims status. Q: What should I do if I lose the key and my car is locked in a remote place? A: First make sure you are safe. Then use your breakdown/roadside cover to move the vehicle to a safe area if needed. Then call an emergency auto locksmith to attend and provide a replacement. Need a reliable solution now?

How to Program a Car Key: A Step-by-Step Guide

Lost Your Car Key Programming? Here's What to Do Have you ever lost your car keys or found yourself with a spare key that doesn’t start your vehicle? While the process of programming a car key might seem intimidating, it’s often simpler than you’d expect. In many cases, car owners can program keys themselves without needing a visit to a dealership. This guide walks you through the essentials of car key programming, helping you save time, effort, and potentially a significant amount of money. Understanding Car Key Programming: The Basics Car key programming is the process of syncing a key with a car's internal computer so it can communicate securely. Modern vehicles use transponder keys or smart keys equipped with chips that emit a unique signal. Without proper programming, these keys won’t function, even if they fit perfectly into the ignition. While older mechanical keys didn’t require programming, today’s advanced systems add a layer of security, reducing the risk of car theft. However, this added sophistication means that replacing or reprogramming a key is no longer as simple as cutting a piece of metal. Quick Tip: Check your vehicle’s owner manual to see if programming your car key is a DIY-friendly process, as some models allow self-programming, while others require professional tools. Step-by-Step Guide to Programming a Car Key Before starting, ensure you have all necessary tools and information: The vehicle’s owner manual. All keys that need programming, including the functional ones. Step 1: Access Programming Mode Start by sitting in the driver’s seat with all the doors closed. Insert the already functional key into the ignition and turn it to the “on” position (do not start the engine). Some vehicles require you to cycle the key between “on” and “off” positions a specific number of times to enter programming mode. Step 2: Add the New Key Once in programming mode, remove the functional key and quickly insert the new key into the ignition. Turn it to the “on” position. The vehicle’s security light may flash to indicate the key has been successfully programmed. Step 3: Test the Key After programming, remove the new key and test it to ensure it can start the car and unlock the doors. Note: Each car manufacturer has unique programming steps. Be sure to consult your owner’s manual or the manufacturer’s website for specific instructions. When Professional Help Is Needed While many vehicles allow for DIY key programming, others require specialized equipment or software that only dealerships or locksmiths can access. This is particularly true for luxury or high-end cars with advanced encryption and security features. If your DIY efforts fail, it’s best to seek help from a certified professional. Visiting a dealership is a reliable, albeit more expensive, option. Alternatively, professional locksmiths often provide programming services at a lower cost, making them a practical choice for many drivers. Costs and Considerations The cost of programming a car key varies significantly based on the vehicle’s make and model. For basic models, self-programming might cost nothing if you already have a functional key. However, professional programming can range from $50 to $300 or more, especially for smart keys or proximity fobs. To minimize costs: Have a spare key : Always keep a functional spare to simplify programming if a replacement is needed. Research costs : Call local locksmiths or dealerships to compare pricing. Empower Yourself with Knowledge Programming a car key doesn’t have to be a daunting task. With the right tools and information, many car owners can handle the process themselves, saving time and money. However, it’s essential to recognize when professional assistance is necessary, particularly for complex key systems. By understanding the basics of car key programming and following a step-by-step approach, you can ensure your vehicle remains secure and functional. So, whether it’s a spare key or a replacement, you now have the confidence to tackle the task or know where to turn for help.

TSA Locks: Why They Matter for Car Owners

TSA Locks: Why They Matter for Car Owners

TSA Locks: Why They Matter for Car Owners As a car owner, you may not immediately consider the importance of a TSA-approved lock for your vehicle, especially when it comes to travel. However, these specialized locks can offer an added layer of security and convenience, particularly when you’re transporting your vehicle or luggage through airports, shipping services, or even while storing it during a trip. But what exactly is a TSA lock, and why should you, as a car owner, care about it? In this article, we break down everything you need to know about TSA locks, how they work, and why they could be beneficial for both you and your vehicle. What is a TSA Lock? A TSA lock is a special type of lock that has been designed to meet the standards set by the Transportation Security Administration (TSA). These locks are typically used for luggage, but their benefits extend to car owners who want to secure their valuables during travel. What sets TSA locks apart from standard locks is their unique feature: TSA agents can unlock these locks using a master key. This allows them to inspect your belongings if needed without damaging your lock or luggage. These locks are often used for suitcases, travel bags, and in some cases, for securing items inside a vehicle while it's being shipped or stored. Why Should Car Owners Consider TSA Locks? While TSA locks are primarily used for luggage, there are several ways car owners can benefit from them: 1. Convenience for Travel If you're shipping your car or using long-term parking at an airport, you may want to secure your vehicle's trunk or compartments. TSA-approved locks give you peace of mind knowing that any inspections required by airport security or shipping agents won't result in your lock being broken. 2. Extra Layer of Security When you’re transporting your vehicle across state lines or internationally, you’ll likely want to keep valuables like electronics, tools, or personal items in the car. A TSA-approved lock ensures that, should security personnel need to access your vehicle, they can do so without causing damage. 3. Compliance with Shipping Regulations Certain vehicle shipping services may require TSA-approved locks as part of their protocols. These locks provide an easy way for shipping carriers to inspect your vehicle without having to call you for permission every time an inspection is necessary. By using TSA-approved locks, you comply with industry regulations and simplify the process. How Do TSA Locks Work? TSA locks are equipped with a special mechanism that allows TSA personnel to unlock them using a universal key. When you use a TSA-approved lock, you set your own combination or use a key for the lock. The TSA agents have access to a master key that fits all TSA locks, allowing them to inspect the contents of your luggage or vehicle safely. These locks are typically used for things like bags, briefcases, or car storage compartments. They provide the added benefit of security, knowing that your belongings are locked but still accessible for inspection when necessary. How to Choose the Right TSA Lock for Your Vehicle If you’re considering a TSA lock for your car, there are a few things to keep in mind: Size and Fit : Make sure the TSA lock fits the compartments or storage areas you intend to secure, whether it’s the trunk, glove box, or internal storage. Durability : Look for locks made of high-quality materials, such as stainless steel or reinforced plastic, to ensure they stand up to wear and tear during transit. Ease of Use : Choose a lock that you can easily open and close but that remains secure against tampering. Approval : Always ensure that the lock you purchase is TSA-approved. You can usually find the TSA logo on the packaging or lock itself. Are TSA Locks Necessary for Every Car Owner? While TSA locks offer multiple benefits, they aren’t absolutely necessary for every car owner. If you rarely travel with your car or if you don’t need to transport it across borders, a standard lock might be sufficient for your needs. However, for those who ship their car regularly or for long-term travelers, TSA-approved locks are a great investment. Whether you're shipping your vehicle, storing it during travel, or just want an extra layer of security, TSA locks can provide the assurance that your belongings remain secure—and that airport security or shipping agents can access your vehicle if needed without causing damage. TSA locks may seem like a small detail, but for car owners who frequently travel, ship their vehicles, or store valuable items inside their cars, they can make a big difference. With the convenience, security, and compliance they offer, TSA-approved locks provide peace of mind, knowing your car and belongings are safe during the travel process. Next time you're preparing for a trip, consider investing in a TSA-approved lock to make your journey a little easier and a lot more secure. This revised blog provides an informative, engaging overview of TSA locks and their relevance to car owners. It emphasizes both convenience and security while addressing the potential benefits for those who travel or ship their vehicles regularly.
