A transponder is a device with Non-Volatile Memory. It contains a set windings, which are delicate wires that are twisted around the tube. They look like the ones in an electric motor. These windings generate a signal for the car to read. If the code is valid, then the car will allow you to start it.

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