Then, clip the outside of the key back together.

Remotes

lexus key cutting remotes and fobs can be difficult to replace and require locksmiths who are both knowledgeable and have the right tools. Some models require the transponder inside the key to be changed to allow it to communicate with the immobiliser system in the car. These chips are programmed using different methods based on the model of Lexus. This is accomplished by using an instrument that sends an electronic signal to the chip which matches the code used to open the doors and start the engine.

Some lexus replacement key cars are designed with a device that combines the key head and the remote. They are simpler to replace, as there is no separate chip required. This kind of key is also cheaper.

Transponder Chips

Transponder chips are found in the key heads of almost all new lexus key cars manufactured since 1995. They can be used to disable immobiliser systems. If you've got keys with a chip in it the head has a plastic cover which can be pulled off to reveal an L-shaped key. The process of getting a replacement key fob that is made using a transponder chip is a multi-stage procedure that includes precise cutting of key replacements and programming the transponder chip so that it can synch up with the vehicle's immobiliser system.

A transponder is an electronic chip with Non-Volatile Memory (NVM) that houses a set of windings (very fine wire wrapped around a tube) that look like the ones in an electric motor. These windings generate a signal that the car can read. If the code is valid, then the car will allow you to start it up.

There are two kinds of transponder chip. The one is known as the 80-bit and the second is called the circle + (General Motors).

When your fob or key is installed in 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 both the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine will not start even in the event that the ignition circuit is short-circuited by a thief.
