The head of a key that contains a transponder chip is able to be removed to reveal a metal L-shaped key. A transponder chip replacement key or fob is a multi-stage procedure. It involves cutting the keys accurately and programming the chip to connect with the vehicle immobiliser.
Transponders are electronic chip that has Non-Volatile Memory (NVM) that houses a set of windings (very fine wire twisted around the tube) that look like the ones found in an electric motor. The windings generate a coded message that the car read. If the code is correct the car will start.
There are two types of transponder chip. The first is called the 80-bit, while the second is called the circle + (General Motors).
