Lexus keys aren't easy to replace. A specialist locksmith is needed to make a spare that works. This is due to the fact that every Lexus key contains an electronic chip that needs to be programmed to sync with your vehicle's immobiliser - if not it will not start.

Remotes

Lexus remotes and fobs can be difficult to replace and require locksmiths who are both knowledgeable and have the right tools. Some models require that the transponder chip contained in the key be changed in order to work with the immobiliser system of the car. The chips are programmed with different methods depending on the model of Lexus. This is done by using an electronic device that transmits an electrical signal to the chip that is compatible with the code used to unlock the doors and start the engine.

Certain Lexus cars are constructed with a single piece of hardware that incorporates the key head and the remote, and these are simpler to replace as no separate chip is required. This type of key can also be a bit cheaper.

Transponder Chips

Transponder chips are found in the key heads of a majority of new cars produced since 1995. They are used to disable immobiliser systems. If you have a key with a chip inside, the head has a plastic cover that can be taken off to reveal an L-shaped metal key. A transponder chip replacement key or fob is a multi-stage procedure. It involves cutting keys precisely and programming the chip to make it sync with the vehicle immobiliser.

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

There are two kinds of transponder chips. One is known as the 80 bit and the other known as a circle + (General Motors). The first is reusable but needs to be unlocked by a special machine to work in another compatible vehicle.
