Certain models require the transponder on the key to be changed in order to function with the immobiliser of the vehicle. The lexus rx300 key cutting models employ different methods to program these chips. This is accomplished by using a special device which transmits a specific code to the chip to unlock the doors or to start the engine.

Some Lexus automobiles are built with a single piece of hardware which includes the key head and remote. These are easier to replace since no separate chip is required. This type of key can also be a little less expensive.

If you've got a key that has a chip inside it, the head comes with a cover that is able to be pulled off to reveal an L-shaped key. A transponder-chip replacement 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's immobiliser.

Transponders are chips with Non-Volatile Memory. It has a set of windings which are fine wires wrapped around a tube. They look like those in an electric motor. These windings transmit a message that the car is able to read. If the code is correct it will allow the car to start.

There are two kinds of transponder chips, one known as the 80 bit, and the other is known as a circle + (General Motors).

Immobiliser Systems

An immobiliser system is an electronic security measure that deters thieves from starting your vehicle. It operates by sending a signal from the vehicle to the key whenever you attempt to start it. The electronic chip inside your key responds by sending an unique code that must match that in the vehicle to start. If the codes do not match, the engine will shut off immediately to prevent theft.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format which is not easily copied. When your fob or key is placed in the ignition, it transmits the code to a receiver in the ECU. The ECU is able to compare this code with the one that is stored in its memory, and activates the fuel system and the ignition circuit if they are compatible. If the codes do not match the engine won't start even in the event that the ignition circuit is short-circuited by a thief.

Replacing a key or fob is a multi-stage process that requires precise cutting of the new blade for the key and programming it to communicate with your car's immobiliser system. There are many different immobilisers used in different models and years and each has its own distinct programming process.
