A transponder is an electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire wrapped around tubes) which look similar to ones found in an electric motor. These windings create a coded message that the car can read. If the code is correct the car will begin to move.

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