Transponder chips are in the keys of nearly all new cars built since 1995. They are used to disarm immobiliser systems. If you've got keys with a chip inside, the head comes with a cover that can be taken off to reveal an L-shaped key. A transponder-chip replacement key or fob is a multi-stage procedure. It involves cutting the keys with precision and programming the chip to make it sync with the vehicle immobiliser.

A transponder is a type of chip that has Non-Volatile Memory. It has a set of windings that are fine wires that are wrapped around a tube. They resemble the ones in an electric motor. The windings generate a coded message that the car read. If the code is valid, then the car will allow you to start it up.

There are two types of transponder chip, the first is called the 80-bit and the second is called the circle + (General Motors). The former can be reused but it needs to be unlocked by a specific machine in order to function in a compatible vehicle. The second kind is more difficult to use as the older keys could be broken, drilled, or thrown out when key cases are changed.

Immobiliser Systems

Immobiliser systems are electronic security devices that stop thieves from starting up your car. It operates by sending a signal from your vehicle to the key when you attempt to start it. The electronic chip in the key responds by sending a unique number of codes that must match the one of the vehicle to allow it to start. If the codes do not match, your engine will shut down immediately to stop theft.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format which cannot be easily copied. When your fob or key is installed in the ignition it transmits this code to a device within the ECU. The ECU is then able to compare it with the code stored in its memory and then activates the ignition and fuel system circuit if they coincide. If the codes don't match, your engine will not start, even if a burglar tries to short-circuit the ignition circuit.

Replacing a fob or a key is a multi-stage process that involves accurate cutting of the new blade of the key and programming it to connect with your car's immobiliser system. There are many different immobiliser systems that are used in different years and models, and each requires its own unique programming procedure.
