Law enforcement officials around the world are constantly facing new challenges when it comes to unscrupulous individuals taking other people’s stuff. The latest challenge for police is the Key Relay Deice that can be used to steal your car by transmitting its fob signal to open and start the car with almost no effort.
Security experts have been aware of the Key Relay Devices since 2011 but in recent years their use has become more wide spread. As you will see from the video below thieves using a key relay device are able to simply stand within the transmission range of your key fob and using a relay transmitter send the signal to another relay device held near your car and hey presto your car is opened. This isn’t a security flaw but a natural by-product of cars using a proximity sensor to unlock the car, if you must press an open the doors button on your fob your car isn’t susceptible to this attack.
