Car Remotes / Keyless Lock Systems
A Keyless Entry System comprises a remote fob or key and a receiver unit in the vehicle which operates the doors/boot.
The remote contains a short-range radio transmitter and depending on make, may work between 5 - 20 meters of the vehicle. When a button is depressed, it sends a code signal to the receiver which locks or unlocks the vehicle. Most Keyless Entry Systems operate on a frequency of 315MHz for North American cars and 433.92MHz for European, Japanese and Asian cars.
Since the mid 1990's encryption has been added to prevent car theives from unlocking vehicles through interception or spoofing of the signal. Some early systems use Infrared instead of Radio Frequencies to transmit the signal.
Remote keys usually include transponder technology.
