Transponders are electronic chip equipped with Non-Volatile memory (NVM) which contains a set of windings (very fine wire twisted around the tube) that look like the ones in an electric motor. These windings form a coded signal that the car can read. If the code is valid, then the car will allow you to start it.

If the codes do not match, your engine will not start - even if an armed robber attempts to short-circuit the ignition circuit.
