If you have a key with a chip inside, the head is covered in a plastic cover that is able to be pulled off to reveal an L-shaped key. A transponder-chip replacement key or fob is a process that involves multiple stages. It involves cutting the keys with precision and programming the chip to sync up with the vehicle's immobiliser.

A transponder is an electronic device with Non-Volatile Memory (NVM) that houses a set of windings (very fine wire twisted around tubes) that resemble ones in an electric motor. These windings generate a signal for the car to read. If the code is correct the car will begin to move.

There are two kinds of transponder chips. The one is known as the 80-bit, while the second is called the circle + (General Motors). The former type is reusable but needs to be unlocked by a machine that is specially designed to function in a different compatible vehicle.

Immobiliser Systems

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