Short answer:
Yes. You can order a replacement car key online in the UK and have it delivered in 3–4 days. Choose the right key type, provide a photo or key code for cutting, and have a local locksmith program it when it arrives.

Why trust this guide:
With over 25 years in the locksmith trade and more than 650,000 satisfied customers, Mr-Key explains exactly how online key replacement works — clearly, securely, and step by step.

When online replacement works (and when it doesn’t)

Ordering online is ideal if you need a spare, a like-for-like remote, or a replacement for a lost or damaged key. It’s the fastest and most convenient way to get OEM-grade parts delivered to your door.

You simply order the correct key, have it cut from a photo or key code, then let a local locksmith program it to your vehicle.

Online ordering doesn’t replace immobiliser pairing. Modern vehicles still require professional programming once the key arrives.

 

Key types explained

Transponder keys
These have a mechanical blade and an electronic chip that communicates with your car’s immobiliser.

Remote fobs
Include lock/unlock buttons plus a built-in transponder. We supply the pre-cut blade (if requested) and tested electronics.

Proximity or smart keys
Keyless entry and push-start units. Delivered ready for your locksmith to pair with the car.

Key shells & batteries

What You Need To Know About BMW  Swirl Flaps and How To Solve The Problem With Them

Swirl flaps are a BMW system that has been introduced to help burn the fuel mixture in the cylinder better due to the fact that diesel engines do not have throttle valves and it is not possible to adjust the air-fuel ratio. A diesel engine without vortex valves operates between a poor and a rich fuel mixture, because the only way to regulate it is through fuel injection. Design of the first generation swirl flaps that are made of made of metal. Unfortunately, swirl flaps are responsible for countless damaged engines and costly repairs due to design errors or metal fatigue. Once damaged, the cylinder sucks them in and causes great damage. This is how damaged valves damage the cylinder. Typical swirl flaps suction damage. The vortex valves are positioned in the inlet and are controlled by vacuum (DDE 4.0) or electrically (DDE5.0 / DDE6.4) by the engine ECU. Effects of malfunctioning valves: Swirl valves are stuck in open position: Deterioration of exhaust gas performance at lower speeds. Swirl valves are stuck in closed position: Approximate power loss of 10% at high engine speeds. How swirl flaps work: Performance characteristics: The vortex valves are in the closed position, at low engine speeds and small amounts of fuel injected (controlled by the ECU card). They open under the following conditions: coolant temperature <14 ° C OR * fuel quantity> 24 mg OR 2. engine speed 2250 rpm OR 3. inlet air temperature <-5 ° C. BMW and Pierburg have decided to produce diesel engines with metal vortex valves. The speed at which the pistons in the diesel engine operate is at least 60 rpm, so a sucked vortex valve will break and cause a number of damages inside the engine. In most cases, one or more pistons are severely damaged, as a bonus you get valves, in some cases a head or turbocharger. And this combination with a BMW engine is like a cumulative jackpot 🙂 In 2004, BMW began work on the problem and improved the design, however, a number of owners reported ongoing problems in this area. The solution to this problem is by removing the vortex valves and plugging, which does not affect the performance of the engine and at the same time, you can safely pass the exhaust test. Engines: M47 (136hp VP44 fuel pump) has no valves. M47N common rail engine (including M47N / M47TU / M47TUD20) (150hp. Face lift model from 2001 -) has valves. M57 engines (M57D) (525d & 187hp. 330d) cars with manual transmission do not have valves, but those with automatic have. M57N engines (M57TUD) (525d & 330d 204hp) have vortex valves. Ruined swirl flapss: The plugs that replace the vortex valves are easy to find on the internet, but you can also find them here on our website. Typical plugs: Disassembly of vortex valves: The vortex valves can be safely dismantled and in most cases if they are removed properly no loss of power is felt. Final list of models for which vortex valves are installed: Engine: M47N/M47TU/M47TUD20 Applications: * 110 kW (148 hp) and 330 N·m (243 lb·ft) o E46 320d 2001-2005 o E83 X3 2.0d (up to end of 2006) Engine: M47TU2D20 The engine was updated again in 2004 as the M47TU2D20.

How to Rescue Your Car Key After It Gets Wet: A Practical Guide

The Modern Dilemma: Wet Car Keys and How to Fix Them Imagine this: you’re caught in an unexpected downpour, and your car key slips from your hand, landing straight into a puddle. Or perhaps you accidentally leave your keys in your pocket while diving into a swimming pool. Whatever the scenario, the moment you realize your car key has been submerged in water can be panic-inducing. With modern car keys embedded with electronic chips and sophisticated technology, exposure to moisture can mean more than just a temporary inconvenience—it could leave you locked out or facing expensive repairs. But before you rush to replace your key, there are several steps you can take to salvage it. Understanding the Risks: What Happens When a Car Key Gets Wet? Car keys today are more than just metal; many include electronic transponders and remote control systems that communicate with the vehicle’s ignition. Water exposure can lead to: Short circuits: Moisture can cause electronic components to malfunction or fail entirely. Corrosion: Over time, water can lead to rust and degradation of internal circuits. Battery failure: Many car keys contain small batteries, and water exposure can lead to leakage or loss of function. While traditional metal keys are less affected by water, smart keys and key fobs are vulnerable. Acting quickly can often save your key from irreparable damage. Immediate Steps to Take When Your Car Key Gets Wet If your car key has been exposed to water, time is of the essence. Here’s what you need to do: Retrieve the key from the water as quickly as possible and wipe off excess moisture using a dry, absorbent cloth or paper towel. Remove the battery if possible since many car key fobs have removable batteries; check your car manual for instructions. If the battery is wet, replace it with a new one rather than attempting to dry and reuse it. Disassemble the key fob if safe to do so, carefully opening the casing to allow internal components to dry. Avoid using force or tools that might damage delicate parts. Use silica gel or rice for drying—place the key fob in a container of silica gel packets (often found in new shoe boxes or electronics packaging) for 24-48 hours; if silica gel is unavailable, uncooked rice can work as an alternative, though it may not be as effective. Avoid using direct heat—do not use hairdryers, microwaves, or ovens to speed up drying, as high temperatures can warp plastic components and damage circuits; instead, allow the key to air dry naturally in a warm, ventilated space. Finally, test the key once you’re confident it is dry by reinserting the battery and testing it on your car; if the key does not work, it may require reprogramming or replacement. When to Seek Professional Help If your key remains unresponsive despite thorough drying, it may have suffered internal damage. In such cases, consider these options: Contact your car manufacturer or dealership—they can provide a replacement key or attempt to reprogram the existing one. Visit a professional locksmith—many automotive locksmiths specialize in repairing and reprogramming electronic keys at a lower cost than dealerships. Check your car insurance policy—some policies cover lost or damaged keys, potentially reducing replacement costs. Global Trends in Key Fob Durability and Waterproofing Car manufacturers are increasingly designing key fobs to withstand water exposure. For example, Tesla’s Model 3 key card eliminates the need for traditional keys by using a waterproof RFID card, Toyota and BMW have introduced water-resistant key fobs, minimizing the risk of damage, and future innovations may include biometric key technology, reducing dependency on physical devices altogether. As technology advances, water-resistant key designs may become the norm, reducing the stress of accidental spills or submersion. Preventative Measures: How to Protect Your Car Key from Water Damage To avoid future incidents, consider these preventative steps: Use a waterproof key case: Available online, these cases provide a protective barrier against water exposure. Designate a dry storage spot: Avoid leaving keys in pockets that may go through the wash or near pools and sinks. Invest in a spare key: Having a backup key can be a lifesaver if your primary key is damaged beyond repair. Check for manufacturer upgrades: Some car brands offer upgraded, water-resistant key fobs for an additional fee. Act Quickly to Save Your Key A wet car key doesn’t necessarily mean it’s the end of the road. By acting swiftly and following proper drying techniques, you may be able to rescue your key without costly replacements. As car technology evolves, so too will key durability, but for now, a little caution and quick thinking can go a long way. If you frequently find yourself around water, taking preventative measures can save time, money, and frustration.

How to Protect Your Car Key Fob from Relay Attacks
25.04.2025

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’s the Difference Between Immobilizer, Transponder Chip, and Key Fob?
02.05.2025

What’s the Difference Between Immobilizer, Transponder Chip, and Key Fob?

In modern vehicles, the once simple car key has evolved into a sophisticated piece of technology. With built-in electronics, anti-theft features, and remote functions, today’s car key is part of a broader ecosystem designed for both convenience and security. Yet with all this advancement comes confusion. Many drivers aren’t sure what terms like immobilizer , transponder chip , and key fob actually mean—or how they relate to one another. This guide breaks down these components in detail, explains how they work together, and clarifies why it matters when you’re replacing, reprogramming, or troubleshooting your car key. What Is an Immobilizer? An immobilizer is an electronic security device installed in most modern cars. Its purpose is to prevent the engine from starting unless the correct key—specifically, the correct coded signal—is detected. When you attempt to start your vehicle, the system searches for a signal from a registered transponder chip. If that signal is missing or incorrect, the immobilizer blocks the ignition system. This means the engine won’t crank or turn over, even if the physical key fits. Immobilizers are embedded in the car’s engine control unit (ECU) and became standard in vehicles after the late 1990s in many countries, in response to rising car theft. They offer a silent, invisible layer of protection against common theft techniques like hotwiring. Without the correct digital authentication, the car simply will not start. What Is a Transponder Chip? The transponder chip is a small electronic microchip located inside the car key or key fob. The word “transponder” is a combination of “transmitter” and “responder.” It is designed to emit a unique code that the car's immobilizer can recognize. When you insert the key into the ignition or bring a key fob close to a push-start system, the chip sends a signal to the car’s ECU. If the code matches the one stored in the car’s database, the immobilizer disables itself and allows the engine to start. Transponder chips are passive. They do not require a battery and are activated by electromagnetic energy from the ignition coil or receiver unit inside the vehicle. Without a functioning or correctly programmed transponder chip, your car will not start—even if the metal key turns in the ignition. What Is a Key Fob? A key fob is the remote control device you carry that allows you to perform functions like locking or unlocking your car, opening the trunk, and activating panic alarms. In modern vehicles, key fobs may also control remote start or proximity-based unlocking features. While key fobs often include a transponder chip inside them, they serve a different function. The key fob operates remote commands via short-range radio signals. The transponder chip, on the other hand, is responsible for enabling or disabling the engine. Smart key fobs, found in many recent vehicles, don’t require insertion into the ignition. Instead, the car detects the fob nearby and permits the engine to start with a button press. If your key fob battery dies, you might still be able to start the car manually if the transponder chip is present and recognized. Most fobs also have a hidden mechanical key inside, which can be used to unlock the door if the electronics fail. How They Work Together Although they are distinct components, the immobilizer, transponder chip, and key fob all work in harmony to secure and operate your vehicle. The immobilizer controls whether the engine is allowed to start. The transponder chip provides the digital identity that must be verified by the immobilizer. The key fob provides wireless control of non-engine functions like locking, unlocking, and trunk access. In most modern cars: You approach the vehicle with the key fob. The fob unlocks the doors. When you start the vehicle, the transponder chip sends a signal to the immobilizer. If the code matches, the engine is authorized to start. If the code doesn’t match, or if the chip is missing or damaged, the engine remains disabled—even if the rest of the key’s functions work perfectly. Why This Knowledge Matters Understanding how your car key works is essential when: Replacing a lost or broken key Buying a spare or duplicate Diagnosing why your car won’t start Choosing between locksmith and dealership services For example, if your key fob unlocks your car but won’t start it, the issue may lie with the transponder chip, not the battery. Conversely, if your fob doesn’t lock or unlock the car remotely, the chip may still be functional, and the issue could simply be a dead battery. Replacing a key without properly programming the transponder chip will result in a non-starting vehicle, even if the key physically fits and the remote works. For reliable replacement keys, fobs, batteries, and accessories, visit our Car Key Collection. Car keys are no longer just mechanical tools. They’re complex, multi-function devices that combine security, convenience, and connectivity. By understanding the role of the immobilizer , transponder chip , and key fob , you’ll not only protect your vehicle better, but also avoid costly mistakes when dealing with repairs or replacements. Whether you’re troubleshooting a non-starting car or simply trying to replace a damaged key, knowing the difference between these three elements gives you the clarity and confidence to take the right action.
