Key Programming

We have the facility to programme transponder ignition keys.

A transponder is a chip in the head of your car key which, when inserted into the ignition, sends a signal telling the Engine Control Unit (ECU) that it is okay for the car to start because the correct key has been used.

The transponder sends the signal from the chip in the key to the antenna around the ignition and then from the ignition antenna to the vehicles ECU. On receiving this coded message the ECU gives the go ahead to the starter motor, ignition and fuel systems.
