Transponder Chips

The majority of new cars built since 1995 have transponder chips in the head of the key to disable the immobiliser system. The head of a key which has a transponder chip can be removed to reveal a steel L-shaped key. Having a replacement key or fob made with transponder chips is a multi-stage process which involves precise cutting of replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser system.

A transponder is an electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire twisted around the tube) that look like the ones in an electric motor. The windings create a coded signal that the car can read. If the code is correct the car will start.

There are two kinds of transponder chips. The one is known as the 80-bit and the second is known as the circle + (General Motors). The former type is reusable but must be delocked by a machine that is specially designed to be used in a compatible vehicle. The latter type is more difficult because the previous keys are usually damaged and then drilled through or discarded after key cases are replaced. They can be salvaged, however and then used to create the service key, which doesn't require a battery in order to function.

Immobiliser Systems

An immobiliser is an electronic security feature which prevents thieves from opening your vehicle. It operates by sending an electronic signal from the vehicle to the key every time you try to start it. The electronic chip inside your key responds with an individual code that must match the one found in the vehicle in order to start. If the codes don't match, your engine will stop immediately and prevent theft of your car.

Modern smart keys and fobs have an embedded transponder chip that stores security information in a format that can't be easily duplicated. When the fob or key are inserted in the ignition, they transmit this code to the ECU. The ECU examines the code against the one in its memory, and activates the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine will not start - even if a thief tries to short-circuit the ignition circuit.

The replacement of keys or fobs involves a multi-stage process that includes cutting the new key blade with precision and programming it to ensure that it is compatible with your car's systems. There are a variety of immobilisers used in different years and models, and each requires an individual programming procedure.
