Keys

Lexus keys are not easy to replace and require a professional locksmith for replacing car keys to make a functioning spare. This is because every Lexus key has microchips that need to be programmed in order to synchronise with your vehicle's immobiliser in case it does not. If it doesn't, the vehicle will not be able to start.

You will find one or two screws on the back of the fob for the key. Unscrew them and store them securely (they are small and easy to lose). The fob is removed, revealing an indentation of a circular shape where the metal key will be.

Remotes

Certain models require that the transponder chip within the key be programmed to function with the immobiliser of the car. These chips are programmed by different methods, based on the model of lost lexus key. This is done by making use of a special device that transmits a specific code to the chip to unlock the doors or to start the engine.

Some lexus key cutting automobiles are built with a single piece of hardware that includes the key head and remote. These are easier to replace since there is no separate chip. This type of key can also be a bit cheaper.

Transponder Chips

Transponder chips are in the key heads of a majority of new cars built since 1995. They are used to disable immobiliser systems. If you have a key with a chip in it the head is covered with a plastic cover which can be pulled off to reveal an L-shaped metal key. Making a replacement key, or fob made of transponder chips is a multi-stage process that includes precise cutting of key replacements and programming the transponder chip to synch up with the vehicle's immobiliser.

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

There are two kinds of transponder chip. The first is called the 80-bit and the second is known as the circle + (General Motors). The former is reusable but needs to be unlocked by a specific machine in order to function in a different compatible vehicle. The latter is a bit more difficult, as the older ones are often broken and drilled or discarded after key cases are replaced. They are able to be salvaged however and then used to create the service key, which doesn't need a battery to operate.

Immobiliser Systems

Immobiliser systems are electronic security measures that prevent thieves from starting your car. 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 with an individual code that must match that of the vehicle in order to start. If the codes do not match, the engine will shut down immediately and stop the theft of your car.

Modern smart keys and fobs have embedded transponder chips that stores security information in a format that can't be duplicated. When the fob or key are inserted into the ignition, they send this code to the ECU. The ECU compares this code with the one it has stored in its memory and activates both the fuel system and the ignition circuit if they match. If the codes do not match, your engine will not start, even if an armed robber attempts to short-circuit the ignition circuit.

Replacing a fob or key is a multi-stage process that requires precise cutting of the new key blade, and programming it to work with your car's immobiliser system. There are a variety of immobiliser systems used in different years and models and each one requires its own unique programming procedure.
