A transponder is an electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire that is wrapped around tubes) that resemble 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.

There are two kinds of transponder chips. One is known as the 80 bit, and the other referred to as a circle + (General Motors).

The chip inside the key responds with a unique code that must match the one in the vehicle to start. If the codes don't coincide, your engine will immediately shut down to stop theft.

When your key or fob is installed in the ignition it transmits the code to a receiver in the ECU. The ECU then compares it with the code stored in its memory and then activates the ignition and fuel system circuit if they match. If the codes do not match then the engine will not start, even when the ignition circuit is damaged by a thief.
