Some models require the transponder in the key to be changed to allow it to communicate with the immobiliser systems of the car. The lexus new key models use different methods to program these chips. This is done making use of a special device that sends a code to the chip to unlock the doors or to start the engine.

Transponder Chips

Transponder chips are present in the keys of nearly all new cars produced since 1995. They are used to disable immobiliser systems. The head of a key that contains a transponder chip is able to be removed to reveal an L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage procedure. It involves cutting the keys precisely and programming the chip to communicate with the vehicle immobiliser.

Transponders are electronic chip 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. The windings generate a coded message that the car can read. If the code is correct the car will start.

There are two types of transponder chips. One known as the 80 bit and the other one is called a circle + (General Motors). The first type is reusable, however it needs to be unlocked using a special machine in order to work in a different vehicle that is compatible. The latter is a bit more difficult because the previous keys are usually broken and then drilled through or discarded when key cases are replaced.

Immobiliser Systems

Immobiliser systems are electronic security devices that deter thieves from starting your vehicle. It works by sending an electronic signal from the vehicle to the key every time you try 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, your engine will stop immediately to stop theft.

Modern smart keys and fobs come with an embedded transponder chip that stores security information in a format that can't be easily duplicated. When your key or fob is placed in the ignition, it transmits this code to a receiver inside the ECU. The ECU compares this code with the one that is stored in its memory, and activates both the fuel system and the ignition circuit if they are compatible. If the codes don't match, your engine won't be able to start - even if a burglar tries to short-circuit the ignition circuit.

The procedure of replacing the fob or key involves a multi-stage procedure that includes cutting the new blade with precision and programming it so that it syncs with your car's system.
