Certain models require that the chip inside the key be reprogrammed in order to work with the immobiliser of the car. The Lexus rx300 Key models employ different methods to program these chips.

Transponder Chips

Transponder chips are present in the head of the key on almost all new cars manufactured since 1995. They are used to disarm immobiliser systems. If you have a key with a chip in it the head is covered in a plastic cover which can be pulled off to reveal an L-shaped metal key. A transponder-chip replacement key or fob is a process that involves multiple stages. It involves cutting keys precisely and programming the chip to communicate with the vehicle immobiliser.

Transponders are electronic chip with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire that is wrapped around tubes) that look like the ones in an electric motor. These windings form a coded signal that the car can read. If the code is correct then the car will allow you to start it up.

There are two types of transponder chips, the one is known as the 80-bit and the other is known as the circle + (General Motors). The former is reusable but needs to be unlocked with a special device to function in a different compatible vehicle. The latter is a bit more difficult, as the older keys are usually broken or drilled through, or discarded when key cases are replaced. However they can be used with a key-service that does not require batteries.

Immobiliser Systems

An immobiliser is an electronic security measure that deters thieves from starting your car. It operates by sending an electronic signal from the vehicle to your key each time you try to start it. The electronic chip in the key responds with a unique code which must match that in the vehicle in order to start. If the codes don't match, the engine will shut down immediately and prevent theft of your vehicle.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format which cannot be easily copied. When the fob or key are inserted into the ignition, they transmit this code to the ECU. The ECU analyzes this code in comparison to the one stored in its memory, and then activates both the fuel system as well as the ignition circuit if they match. If the codes do not match, the engine will not start even when the ignition circuit is short-circuited by a burglar.

Replacing a key or fob is a multi-stage process that involves precise cutting of the new blade of the key and programming it to work with the immobiliser system of your vehicle.
