Some models require that the transponder chip within the key be reprogrammed to function with the immobiliser of the car. The Lexus models use different methods to program these chips. This is accomplished by making use of a special device that transmits a specific code to the chip to unlock the doors or start the engine.

Transponder Chips

More or less all new cars made since 1995 include transponder chips embedded in the head of the key to disable the immobiliser system. If you've got a key that has a chip inside it, the head is covered with a plastic cover that can be pulled off to reveal an L-shaped key. A transponder chip replacement key or fob is a multistage process. It involves cutting the keys with precision and programming the chip to make it sync with the vehicle's immobiliser.

A transponder is a device that has Non-Volatile Memory. It has a set windings which are fine wires coiled around a tube. They look similar to those in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct then the car will allow you to start it.

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 first is reusable, but it must be unlocked using a special machine to function on a different vehicle compatible with it. The latter is more difficult because the previous keys are usually damaged and drilled or thrown away when key cases are replaced.

Immobiliser Systems

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