  • How to Protect Your Car Key Fob from Relay Attacks
Post Name
25.04.2025

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.

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?

Common Car Key Problems and Solutions Every Driver Should Know

There’s nothing quite as frustrating as standing outside your car, key in hand, only to realize something’s not working. Whether your key won’t turn, the remote isn’t responding, or the key itself has seen better days, car key problems seem to happen at the worst possible moment. The good news? Most of these issues are avoidable or fixable, and knowing what to expect can save you both time and stress. 1. Worn-Out Key Blades You might not notice it happening, but over time, your key blade wears down. Each time you insert it into the lock or ignition, tiny grooves and cuts on the blade experience friction. After years of use, the edges get smooth, and the key may stop fitting snugly. Suddenly, you find yourself jiggling or forcing it, risking more damage. The solution here is simple: if you start noticing that the key feels loose or takes a few tries to turn, it’s time to get a replacement cut based on the original code, not by copying the worn-out key. A fresh, precisely cut key blade will fit and function perfectly, preventing damage to your lock cylinder. 2. Dead Key Fob Battery Modern cars often come with remote keys or keyless entry systems, and while they offer convenience, they also rely on tiny batteries. One day, you press the button, and nothing happens—no lights, no unlock sound, no response. Before assuming the worst, check the battery. Typically, key fob batteries (like CR1620 or CR2032 types) are inexpensive and easy to replace. A quick change will often restore full functionality. Make it a habit to change your key battery every 1-2 years, especially if you notice reduced range or need to press the button multiple times. 3. Key Not Turning in the Ignition You get into your car, insert the key, and suddenly it won’t turn. You might try wiggling the steering wheel or pushing the key harder, but nothing works. More often than not, the problem is either with the steering lock mechanism being engaged or dirt buildup inside the ignition cylinder. First, try gently moving the steering wheel side-to-side while turning the key—sometimes the wheel locks under tension, and this simple trick unlocks it. If the problem persists, there could be debris inside the ignition. Using a can of compressed air to blow out dust and tiny particles can help, but if it continues, a professional cleaning or inspection might be necessary before the key or ignition gets damaged. 4. Broken or Bent Keys You might not think twice when you use your key to open a package or pry something open—but keys aren't made for multitasking. Over time, rough handling, bending, or dropping your key can weaken the metal. Eventually, you could end up with a bent key that struggles to fit, or worse, a snapped key stuck in your lock. If your key has visible bends or cracks, don’t wait. Replacing it before it breaks entirely can save you the headache of needing an extraction service. Also, always carry a spare key, just in case. 5. Key Programming Issues If your car uses a transponder key or a smart key, there’s more than just a metal blade involved. Inside is a chip programmed to communicate with your car’s immobilizer system. If your key loses synchronization—maybe after battery replacement, an electrical issue, or accidentally resetting your system—it can leave you unable to start your vehicle. In these cases, reprogramming the key is necessary. Some cars allow you to do this manually following specific sequences (like turning the ignition on and off), but others require specialized diagnostic tools. Familiarizing yourself with your car’s manual or researching the process beforehand helps avoid surprises. 6. Water Damage Dropped your key in water or left it exposed to rain? Electronics inside remote keys and smart keys aren’t waterproof. Moisture can short-circuit internal components, causing the key to stop functioning entirely. If this happens, act fast. Remove the battery immediately and dry out the key as thoroughly as possible. You can use silica gel packets or place the key in a bowl of rice overnight to absorb moisture. However, water damage isn’t always reversible, so keeping your key away from wet environments is the best precaution. Car key problems often feel like an emergency when they strike, but most of them are preventable or quickly fixable with a little know-how. Paying attention to the warning signs—whether it’s a key that’s worn, a fob that’s sluggish, or a key that won’t turn—allows you to act before things escalate. Understanding how your key works and handling it with care will save you from unnecessary stress (and unexpected expenses) down the road. So next time something feels off with your key, remember: a little attention now can prevent a major hassle later.

Over time, thieves have developed methods to bypass or pick mechanical locks, making them less effective for modern vehicle security. However, many vehicles still rely on these locks, and they remain a crucial part of the overall security system. Transponder Keys: A Step Up in Security In response to the vulnerabilities of mechanical key locks, the automotive industry introduced transponder keys in the 1990s. A transponder key is equipped with a microchip embedded inside the key fob. When the key is inserted into the ignition, the microchip sends a signal to the vehicle's engine control unit (ECU), verifying that the key is legitimate and authorized to start the car. Transponder keys significantly enhance vehicle security by making it much more difficult for thieves to clone the key. Without the proper code, the car won’t start, even if the thief has an exact replica of the physical key. This added layer of security has made transponder keys the industry standard in many vehicles. Keyless Entry Systems: Convenience Meets Security Keyless entry systems, also known as remote entry systems, are now common in modern vehicles. These systems allow you to unlock or lock your car without inserting a key. Instead, the car communicates wirelessly with a key fob, sending a unique signal that grants access. The key fob typically includes buttons to lock or unlock the doors and sometimes to start the engine remotely. The convenience of keyless entry is undeniable, but it also introduces certain vulnerabilities. Keyless entry systems rely on wireless signals, which can sometimes be intercepted or duplicated by thieves using sophisticated equipment. To counteract these risks, manufacturers have developed enhanced encryption protocols and rolling codes that change each time the system is used, making it more challenging to hack into the system. Smart Keys: The Next Level of Vehicle Security Smart keys represent the latest evolution in vehicle security. These keys go beyond the capabilities of traditional key fobs and keyless entry systems by offering features like proximity sensing and push-to-start functionality. Smart keys allow you to unlock and start your vehicle without physically touching the key fob. The system detects when the key fob is near the car and grants access automatically. Smart keys are highly secure, as they use advanced encryption methods and rolling codes to protect the vehicle from unauthorized access. In addition, the vehicle can be programmed to disable the engine if an unauthorized key is detected, providing an additional layer of security. International Security Standards for Vehicle Locks To ensure the security of vehicles globally, several international standards have been developed to guide manufacturers in creating secure key lock systems. Some of the most important standards include: ISO 9001 : This standard focuses on the quality management of products, including vehicle locking systems. It ensures that manufacturers meet specific quality control guidelines, which helps ensure the reliability and security of key lock systems. ISO 14298 : This is a more specific standard related to secure key management for vehicles, focusing on preventing unauthorized duplication and tampering with vehicle keys.
