Remotes

Certain models require the transponder inside the key to be changed to work with the immobiliser systems of the car. The chips are programmed using different methods based on the model of Lexus. This is done by using a special device that sends a code to the chip to unlock the doors or start the engine.

The head of a key that is equipped with a transponder chip may be removed to reveal a metallic L-shaped key. A replacement key or fob that is made using transponder chips is a multi-stage procedure that includes precise cutting of replacement keys as well as programming the transponder chip in order to synch up with the vehicle's immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire that is wrapped around tubes) that resemble ones 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 types of transponder chips, one known as the 80 bit, and the other is known as a circle + (General Motors). replacement lexus car key is reusable, but it must be unlocked with a special machine to function on a different vehicle compatible with it.

Immobiliser Systems

Immobiliser systems are electronic security measures which prevent thieves from starting your car. It works by sending an electronic signal from the car to the key whenever you attempt to start it. The electronic chip in the key responds by sending a unique number of codes that must match that of the vehicle in order for it to start. If the codes don't match, the engine will shut down immediately to stop theft.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format which cannot be easily copied. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU compares this code with the one that is stored in its memory, and it activates both the fuel system and the ignition circuit if they match. If the codes do not match the engine won't start, even when the ignition circuit has been short-circuited by a thief.

The replacement of the fob or key requires a multi-stage procedure that includes cutting the new key blade accurately and programming it so that it works with your car's system.
