Remotes

Transponders

Transponders are installed on many modern cars to help protect against theft of cars. These small devices, that are attached to the key fob include a chip and can communicate with the car when it is within the range. These chips utilize a number to identify the car and key.

The chip transmits the signal which is detected by coils that are positioned around the ignition barrel in the vehicle. The coils activate when the key is within reach and send a signal of electromagnetic energy to the transponder chip. The chip responds by sending an identification code unique to the car. The unique code can then be used to unlock doors or start the car.

Immobilisers
