A transponder is a type of chip with Non-Volatile Memory. It has a set of windings that are fine wires coiled around the tube. They look like those in an electric motor. These windings form a coded signal for the car to read. If the code is correct it will allow the car to start.

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