Transponder car keys

Sales Galmier - Wednesday, September 16, 2015

Did you know that from 1996 the majority of Australian vehicles use a Transponder Car key. This key contains an electronic chip, that once a radio signal is sent from the cars computer the transponder key “responds” with the correct code, and the engine is then able to be started. If the car is attempted to be started with a key without a transponder chip, or it is the wrong key, the car will immobilize.

Sometimes it may be difficult to determine whether a car key contains a transponder chip. As it may appear to be the old style car key with a plastic head, but the chip is small and can only be detected with specialist equipment.

You may also not be aware that the buttons on the remote control for your car are actually separate to the transponder component of the key, and their purpose is to control the cars central locking.
