A transponder is a type of chip with Non-Volatile Memory. It contains a set windings that are fine wires that are wrapped around the tube. They resemble the ones 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 chips. One called the 80 bit and the other known as a circle + (General Motors).

Immobiliser Systems

Immobiliser systems are electronic security devices that stop thieves from starting up your car. It operates by sending a signal from the vehicle to the key when you attempt to start it.

Modern smart keys and fobs have an embedded transponder, which stores electronic security information in a format which is not easily copied. When your fob or key is put into the ignition, it transmits this code to a receiver within the ECU. The ECU examines the code against the one in its memory and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes don't match, the engine will not start, even if the ignition circuit is cut off by a criminal.
