Some models require the transponder within the key to be reprogrammed to allow it to communicate with the immobiliser systems of the car. The chips are programmed with different methods based on the model of Lexus. This is done by making use of a special device that transmits a code to the chip to unlock the doors or to start the engine.

Certain Lexus cars are designed with a single piece of hardware that consists of the key head as well as the remote. These are much easier to replace because there is no separate chip. This type of key is also a bit cheaper.

More or less all new cars built since 1995 have transponder chips in the key head to disarm the immobiliser system. If you've got a car key with a chip inside, the head is covered with a plastic cover that can be pulled off to reveal an L-shaped metal key. A transponder-chip replacement lexus key key, also known as a fob is a multi-stage procedure. It involves cutting keys precisely and programming the chip to sync up with the vehicle immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire that is wrapped around the tube) that resemble ones found in an electric motor. These windings produce a coded message that the car is able to read. If the code is correct, the car will start.

There are two types of transponder chip, the one is known as the 80-bit and the second is called the circle + (General Motors). The first is reusable but it needs to be unlocked by a machine that is specially designed to work in another compatible vehicle.

Immobiliser Systems

Immobiliser systems are electronic security devices that stop thieves from starting your vehicle. It operates by sending a signal from the vehicle to the key when you attempt to start it. The chip inside your key responds with an individual code that must match the one found in the vehicle to start. If the codes don't match, the engine will stop immediately to prevent theft.

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