Then, clip the inside of the key back together.

Remotes

Replacing a Lexus remote or fob can be an extremely complex process that requires skilled locksmiths equipped with the right tools as well as knowledge. Some models require that the transponder chip contained in the key be programmed in order to work with the immobiliser of the car.

Transponder chips are present in the key heads of a majority of new cars built since 1995. They can be used to disarm immobiliser systems. If you have a key with a chip inside, the head is covered with a plastic cover which can be pulled off to reveal an L-shaped metal key. A replacement key or fob that is made using a transponder chip is a multi-stage method that includes accurate cutting of the key replacements and programming the transponder chip to synch up with the vehicle's immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) which contains a set of windings (very fine wire twisted around the tube) that look like the ones found in an electric motor. These windings form a coded signal for the car to read. If the code is valid, then the car will allow you to start it.

There are two types of transponder chip, the one is known as the 80-bit while the other is known as the circle + (General Motors). The first kind is reusable, however it needs to be delocked using a specific machine to function on another compatible vehicle. The second type is more difficult to use due to the fact that the old keys can be broken, drilled, or thrown out when key cases are changed.

Immobiliser Systems

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

When your key or fob is installed in the ignition it transmits the code to a receiver in the ECU. The ECU compares this code with the one in its memory, and then activates both the fuel system as well as the ignition circuit if they match. If the codes don't match and the engine does not start even if the ignition circuit is short-circuited by a thief.

The procedure of replacing the fob or key requires a multi-stage process that includes cutting the new blade accurately and programming it so that it can be synced with the car's system. There are many different immobiliser systems that are used in different models and years, and each requires the use of a unique programming method.
