Your car can be stolen in seconds !

Relay attack is a form of keyless car theft. Criminals bypass the keyless entry security by extending the signal of the car key from inside the home. This happens silently and very quickly.

Automobile associations, insurance companies and many other car experts warn of safety problems in cars with a Keyless Entry system. Thousands of cars are stolen by Relay Attack every year and this type of Keyless Entry theft is increasing daily.
