Transponders are electronic chip that has Non-Volatile Memory (NVM) that houses a set of windings (very fine wire wrapped around a tube) which look similar to ones found in an electric motor. These windings produce a coded message that the car can read. If the code is correct, then the car will allow you to start it.

Immobiliser Systems

An immobiliser system is a digital security device which prevents thieves from opening your car. It operates by sending an electronic signal from the car to the key whenever you try to start it.

If the codes don't match, the engine won't be able to start - even if a burglar tries to short-circuit the ignition circuit.
