The head of a key that contains a transponder chip is able to be removed to reveal a steel L-shaped key. Having a replacement key or fob made of a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys and programming of the transponder chip to synch up with the vehicle's immobiliser.

A transponder is an electronic chip with Non-Volatile Memory (NVM) that houses a set of windings (very fine wire twisted around tubes) which look similar to ones in an electric motor. These windings create a coded message that the car will read. If the code is correct, the car will start.

There are two types of transponder chip. The one is known as the 80-bit, while the second is called the circle + (General Motors). The first one is reusable, however it needs to be delocked using a specific machine in order to work on a different vehicle compatible with it. The second one is more difficult to use because the old ones can be broken, drilled, or removed when key cases are changed. However they can be used with a service-key that does not require a battery.

Immobiliser Systems

An immobiliser is an electronic security measure which prevents thieves from opening your car. It works by sending a signal from your vehicle to your key when you attempt to start it.

If the codes don't match, your engine will shut down immediately, preventing theft of your vehicle.

Modern smart keys and fobs have embedded transponder chips that stores electronic security in a format that can't be duplicated. When the fob or key is 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. It then activates the ignition and fuel system circuit if the two match. If the codes do not match, your engine will not start, even if an armed robber attempts to short-circuit the ignition circuit.
