Transponder Chips

Transponder chips are in the key heads of almost all new vehicles manufactured after 1995. They are used to disable immobiliser systems. If you've got a car key with a chip, the head is covered in a plastic cover which can be pulled off to reveal an L-shaped metal key. Having a replacement key or fob with a transponder chip is a multi-stage process which includes precise cutting of the replacement keys and programming of the transponder chip so that it can synch up with the vehicle's immobiliser system.

A transponder is a type of chip that has Non-Volatile Memory. It has a set windings that are delicate wires that are twisted around a tube. They look like those in an electric motor. These windings create a coded message that the car is able to read. If the code is correct then the car will allow you to start it up.

There are two kinds of transponder chips. One is called the 80 bit and the other one is called a circle + (General Motors).

Immobiliser Systems

An immobiliser system is an electronic security feature that deters thieves from starting your car. It works by sending a signal from your vehicle to the key whenever you attempt to start it.

If the codes don't match, the engine will stop immediately and stop the theft of your vehicle.

Modern smart keys and fobs contain an embedded transponder, which stores electronic security information in a format that cannot be easily copied. When the key or fob are inserted in the ignition, they send this code to the ECU. The ECU then compares it to the code in its memory, and activates the ignition system and fuel circuit if the two match. If the codes don't match the engine won't start, even when the ignition circuit has been damaged by a thief.
