Some models require the transponder within the key to be reprogrammed in order to function with the immobiliser of the vehicle. The Lexus models employ different methods to program these chips. This is accomplished by using a special device that sends an electrical signal to the chip which matches the code used to open the doors and start the engine.

Certain lexus car key copy vehicles are designed with a unit that combines the key head and the remote. These are easier to replace, since there is no separate chip needed. This kind of key may also be a bit cheaper.

Transponder Chips

Transponder chips are in the keys of nearly all new cars built since 1995. They are used to disable immobiliser systems. If you've got a key with a chip in it the head has a plastic cover that can be pulled off to reveal an L-shaped metal key. The process of getting a replacement key fob with transponder chips is a multi-stage process that includes precise cutting of the replacement keys and programming of the transponder chip to link up with the vehicle's immobiliser.

A transponder is a chip that has Non-Volatile Memory. It is comprised of a set of windings that are fine wires coiled around the tube. They look like the ones in an electric motor. These windings create a coded message that the car is able to read. If the code is correct, then the car will allow you to start it up.

There are two kinds of transponder chip, 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 specific machine in order to work in another compatible vehicle. The latter one is more difficult as the old keys are usually damaged and drilled or thrown away when key cases are replaced. They are able to be salvaged however, to use with the service key, which doesn't need a battery to operate.

Immobiliser Systems

An immobiliser is an electronic security measure that stops thieves from starting your vehicle. It works by sending an electronic signal from the car to the key each time you try to start it. The chip inside the key responds with an individual code that must match that of the vehicle to start. If the codes do not match, the engine will shut off immediately to prevent theft.

Modern smart keys and fobs contain an embedded transponder, which stores electronic security information in a format which can't be copied easily. When your fob or key is inserted into the ignition, it transmits the code to a device within the ECU. The ECU analyzes this code in comparison to the one that is stored in its memory, and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes do not match, the engine will not start, even in the event that the ignition circuit is cut off by a criminal.
