A transponder is an electronic chip with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire twisted around a tube) that resemble ones found in an electric motor. These windings produce a coded message that the car can read. If the code is correct the car will start.

There are two types of transponder chip, one known as the 80 bit, and the other one is called a circle + (General Motors).

An immobiliser is an electronic security feature that prevents thieves from starting your car. It operates by sending a signal from the vehicle to the key whenever you attempt to start it.
