Transponder Chips

The head of a key that has a transponder chip can be removed to reveal a steel L-shaped key. A replacement key or fob that is made using a transponder chip is a multi-stage process that includes accurate cutting of the replacement keys and programming of the transponder chip so that it can synch up with the vehicle's immobiliser system.

A transponder is an electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire that is wrapped around a tube) that look like the ones in an electric motor. The windings create a coded signal for the car to read. If the code is correct, the car will start.

There are two types of transponder chips. One known as the 80 bit and the other known as a circle + (General Motors).

If the codes do not match, your engine won't be able to start - even if an armed robber attempts to short-circuit the ignition circuit.
