A transponder is an electronic device with Non-Volatile Memory (NVM) that has a set of windings (very fine wire wrapped around tubes) that resemble ones found in an electric motor. These windings transmit a 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 chip, the first is called the 80-bit, while the second is known as the circle + (General Motors).

When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU will then check it against the code that is stored in its memory and then activates the ignition and fuel system circuit if they match. If the codes don't match, the engine will not start even when the ignition circuit has been short-circuited by a burglar.
