Some models require that the chip inside the key be programmed to function with the car's immobiliser system. These chips are programmed by different methods, based on the model of Lexus. This is accomplished making use of a special device that sends a code to the chip to unlock the doors or start the engine.

Some Lexus cars are equipped with a single piece of hardware which includes the key head and remote. These are easier to replace since there is no separate chip. This kind of key could also be a bit cheaper.

Transponder Chips

Transponder chips can be found in keys of nearly all new vehicles manufactured after 1995. They can be used to disable immobiliser systems. If you've got keys with a chip in it the head is covered in a plastic cover that can be taken off to reveal an L-shaped metal key. A replacement key or fob made of transponder chips is a multi-stage process which includes precise cutting of replacement keys as well as programming the transponder chip to synch up with the vehicle's immobiliser.

A transponder is an electronic chip with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire wrapped around the tube) that look like the ones in an electric motor. The windings create a coded signal for the car to read. If the code is valid, then the car will allow you to start it.

There are two kinds of transponder chips. The one is known as the 80-bit, while the second is known as the circle + (General Motors). The first kind is reusable, but it must be delocked using a specific machine in order to work in a different vehicle that is compatible. The latter is more difficult as the old ones are often broken lexus key or drilled through, or discarded when key cases are replaced. They can be salvaged however and then used to create the service key, which doesn't require a battery in order to function.

Immobiliser Systems

Immobiliser systems are electronic security devices that prevent thieves from starting up your vehicle. It operates by sending an electronic signal from the car to the key each time you try to start it. The electronic chip inside your key responds by sending a unique code that must match that of the vehicle to start. If the codes aren't compatible, the engine will shut down immediately and prevent theft of your vehicle.

Modern smart keys and fobs come with embedded transponder chips that stores security information in a format that cannot be easily duplicated. When your fob or key is placed in the ignition, it transmits this code to a receiver inside the ECU. The ECU is then able to compare it with the code in its memory and then activates the ignition and fuel system circuit if the two coincide. If the codes do not match, the engine won't be able to start - even if someone tries to short-circuit the ignition circuit.

The procedure of replacing keys or fobs involves an entire process that involves cutting the new key blade with precision and programming it to ensure that it syncs with your car's security system.
