Certain models require the transponder within the key to be programmed so that it can work with the immobiliser system in the car. The Lexus models employ different methods to program these chips. This is done by using a special device which sends a code to the chip to unlock the doors or to start the engine.

Some Lexus vehicles are equipped with a system that combines the key head and remote. They are easy to replace, since there is no separate chip required. This kind of key is also cheaper.

Transponder Chips

Transponder chips are present in the key heads of almost all new cars built since 1995. They can be used to disarm immobiliser systems. The head of a key which is equipped with a transponder chip may be removed to reveal an L-shaped key. Having a replacement key or web.skku.edu fob with a transponder chip is a multi-stage method that includes precise cutting of key replacements and programming the transponder chip in order to synch up with the vehicle's immobiliser.

Transponders are electronic device with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire wrapped around the tube) that resemble ones found in an electric motor. These windings transmit a message that the car is able to read. If the code is valid, then the car will allow you to start it.

There are two kinds of transponder chips. One known as the 80 bit, and the other one is called a circle + (General Motors). The first kind is reusable, but it must be unlocked using a special machine to function on a different vehicle compatible with it. The latter is a bit more difficult because the previous keys are usually broken and drilled or discarded when key cases are replaced. They are able to be salvaged however, to use with the service key, which doesn't require a battery in order to operate.

Immobiliser Systems

An immobiliser is a digital security device which prevents thieves from opening your car. It operates by sending an electronic signal from the car to your key each time you attempt to start it. The electronic chip in the key responds by transmitting a unique code that must match that of the vehicle to allow it to start. If the codes aren't compatible, the engine will stop immediately, preventing theft of your car.

Modern smart keys and fobs feature an embedded transponder chip that stores electronic security in a format that cannot be easily duplicated. When your fob or key is inserted into the ignition, it transmits the code to a receiver in the ECU. The ECU is then able to compare it with the code that is stored in its memory. It then activates the fuel system and ignition circuit if they coincide. If the codes do not match then the engine will not start, even when the ignition circuit is short-circuited by a thief.

The process 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 is compatible with your car's security system. There are many different immobiliser systems that are used in different models and years and each one requires its own unique programming procedure. We utilize Ross-Tech software to ensure that your replacement key is programmed correctly for optimal performance and security.
