A transponder is a chip with Non-Volatile Memory. It is comprised of a set of windings, which are very fine wires that are wrapped around a tube. They look like the ones in an electric motor. These windings form a coded signal that the car can 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 is known as a circle + (General Motors).

Immobiliser Systems

An immobiliser is a digital security device that stops thieves from starting your car. It operates by sending an electronic signal from your car to your key each time you try to start it.

When your key or fob is put into the ignition, it transmits the code to a device within the ECU. The ECU is able to compare this code with the one it has stored in its memory, and activates both the fuel system as well as the ignition circuit if they match. If the codes don't match, the engine will not start - even if a burglar tries to short-circuit the ignition circuit.
