Remotes

Lexus remotes and fobs can be difficult to replace and require locksmiths who are skilled and possess the appropriate tools. Certain models require the transponder within the key to be reprogrammed so that it can work with the immobiliser systems of the car. These chips are programmed by different methods depending on the model of Lexus. This is accomplished using a specific device that transmits a specific code to the chip to unlock the doors or start the engine.

Transponder Chips

Most new cars since 1995 have transponder chips within the key head that allow it to deactivate the immobiliser system. The head of a key that contains a transponder chip is able to be removed to reveal a steel L-shaped key. Having a replacement key or fob with a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys as well as programming the transponder chip to link up with the vehicle's immobiliser system.

A transponder is an electronic chip with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire coiled around tubes) that look like the ones in an electric motor. The windings generate a coded message that the car can read. If the code is correct, then the car will allow you to start it up.

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

The chip inside the key responds by transmitting a unique code that must match that of the vehicle to allow it to start. If the codes don't match, your engine will stop immediately and prevent theft of your car.

Modern smart keys and fobs are equipped with an embedded transponder which stores electronic security information in a format that cannot be easily copied. When your key or fob is installed in the ignition it transmits this code to a device within the ECU. The ECU then compares it with the code that is stored in its memory, and activates the ignition system and fuel circuit if the two match. If the codes don't match and the engine does not start even if the ignition circuit is short-circuited by a burglar.
