Certain models require the transponder in the key to be programmed to work with the immobiliser of the vehicle. The lost lexus key models use different methods to program these chips. This is accomplished using a special device which transmits a code to the chip to unlock the doors or start the engine.

Some Lexus vehicles are designed with a unit that combines the key head and remote. They are simpler to replace, as there is no separate chip to replace. This type of key can also be a bit less expensive.

The head of a key that is equipped with a transponder chip may be removed to reveal a metal L-shaped key. Having a replacement key or fob that is made using transponder chips is a multi-stage process which involves precise cutting of replacement keys as well as programming the transponder chip so that it can synch up with the vehicle's immobiliser system.

Transponders are chips that has Non-Volatile Memory. It has a set windings which are fine wires coiled around a tube. They look like those in an electric motor. These windings transmit a message that the car is able to read. If the code is correct, then the car will allow you to start it.

There are two types of transponder chip, the one is known as the 80-bit and the other is called the circle + (General Motors).

Immobiliser Systems

An immobiliser is a security measure that uses electronic technology that stops thieves from starting your car.

Modern smart keys and fobs feature an embedded transponder chip that stores electronic security in a format that can't be easily duplicated. When your fob or key is inserted into the ignition, it transmits the code to a receiver in the ECU. The ECU examines the code against the one that is stored in its memory, and it activates the fuel system and the ignition circuit if they are compatible. If the codes do not match then the engine will not start even when the ignition circuit has been short-circuited by a burglar.
