Dear Resident,

Modern vehicles, equipped with keyless entry systems, can unlock automatically when the key is within close proximity, even from inside a pocket or bag. However, this convenience has come with new risks—specifically, keyless car theft, also known as relay theft.

What is relay theft? Relay theft occurs when criminals use devices to intercept and amplify the signal from your car's key fob, tricking your vehicle into thinking the key is nearby. This allows thieves to unlock the car, start the engine, and drive off—often without leaving a trace. The danger lies in how easily these signals can be captured. Thieves only need to be within a few meters of your key fob to capture its signal, even if the fob is located inside your home, well out of sight.

We are seeing an increase in relay attacks across the West Midlands. Thieves are using relay devices near your car and your key fob, they can amplify that signal and unlock your vehicle. This means that even if your home and car are secure, your vehicle remains at risk as long as your key fob is within range.

How to safeguard your vehicle from relay theft

1. Store keys away from your vehicle
At home, ensure that your car keys, including spares, are kept at a safe distance from your car. Avoid leaving them near windows or doors where signals can be intercepted.

2. Use signal-blocking Pouches
Store your car key fob in a Faraday bag or a similar signal-blocking pouch when not in use. These pouches prevent the key fob's signal from being transmitted, ensuring that thieves cannot capture the signal from outside. Regularly check the effectiveness of these pouches, as some can degrade over time.

3. Reprogram your keys for used cars
If you purchase a second-hand vehicle, it's highly advisable to reprogram the keys. Previous owners may still have access to your car, leaving it vulnerable to unauthorised access.

4. Disable wireless signals on the fob
Some key fobs have the option to disable their wireless signals when not in use. If your key fob offers this feature, it’s a good practice to turn off the wireless signal when you’re not using it, reducing the chances of the signal being intercepted.

5. Layer up your security
While technology can help mitigate some of the risks, physical security devices such as steering wheel locks, immobilisers, or additional security systems remain crucial. These layers of protection can significantly reduce the likelihood of theft, even in the event of a successful relay attack.

6. Talk to your dealership or manufacturer
Many dealerships are now offering free or reduced security upgrades for vehicles made in a particular year.
