If you've got a key with a chip in it the head is covered with a plastic cover that can be pulled off to reveal an L-shaped metal key. A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting keys precisely and programming the chip to make it sync with the vehicle's immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire coiled around tubes) that look like the ones found in an electric motor. These windings transmit a message that the car is able to read. If the code is correct the car will start.

There are two kinds of transponder chip. The first is called the 80-bit while the other is known as the circle + (General Motors). The first one is reusable, but must be delocked using a specific machine to function on another compatible vehicle. The second kind is more difficult to use due to the fact that the older ones could be broken, drilled or toss out when keycases are changed. They can be salvaged, however, to use with an ad-hoc key that does not require a battery to operate.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology that deters thieves from starting your vehicle. It works by sending a signal from your vehicle to the key whenever you attempt to start it. The chip inside your key responds by sending a unique code which must match the one in the vehicle in order to start. If the codes don't match, the engine will shut down immediately, preventing theft of your car.

Modern smart keys and fobs feature an embedded transponder chip that stores security information in a format that cannot be duplicated. When your fob or key is installed in the ignition it transmits this code to a receiver within the ECU. The ECU then compares it to the code that is stored in its memory and then activates the ignition and fuel system circuit if the two coincide. If the codes do not match and the engine does not start, even when the ignition circuit has been damaged by a thief.
