Some models require that the chip inside the key be changed to function with the car's immobiliser system. These chips are programmed by different methods based on the model of Lexus. This is done by using an instrument that sends an indication to the chip that matches the code used to open the doors and start the engine.

Transponder Chips

Transponder chips are present in the key heads of a majority of new cars manufactured since 1995. They can be used to disable immobiliser systems. The head of a key which contains a transponder chip is able to be removed to reveal an L-shaped key. A transponder-chip replacement key or fob is a multistage process. It involves cutting the keys with precision and programming the chip to communicate with the vehicle immobiliser.

Transponders are chips with Non-Volatile Memory. It has a set windings that are fine wires wrapped around the tube. They look like the ones in an electric motor. The windings create a coded signal that the car can read. If the code is correct, the car will start.

There are two kinds of transponder chips, one called the 80 bit and the other is known as a circle + (General Motors). The former is reusable but must be delocked by a machine that is specially designed to function in a different compatible vehicle. The second one is more difficult to use since the old ones can be damaged, drilled or toss out when keycases are changed.

Immobiliser Systems

Immobiliser systems are electronic security measures that stop thieves from starting your vehicle. It works by sending a signal from your vehicle to the key whenever you attempt to start it. The electronic chip in your key then 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 shut off immediately to prevent theft.

Modern smart keys and fobs come with an embedded transponder, which stores electronic security information in a format which cannot be easily copied. When the key or fob is inserted into the ignition, they send this code to the ECU. The ECU examines the code against the one in its memory, and activates the fuel system and the ignition circuit if they match. If the codes do not match, your engine will not start, even if someone tries to short-circuit the ignition circuit.
