Remotes

Lexus remotes and fobs can be difficult to replace and require locksmiths who are experienced and possess the proper tools. Certain models require the transponder on the key to be programmed to work with the immobiliser system in the car. The chips are programmed with different methods based on the model of Lexus. This is accomplished by making use of a special device that sends a code to the chip to unlock the doors or start the engine.

Some Lexus models are built with a unit that combines the key head and the remote. They are simpler to replace since there is no chip that needs to be replaced. This kind of key is also a bit cheaper.

Transponder Chips

Transponder chips can be found in head of the key on almost all new cars produced since 1995. They are used to disable immobiliser systems. The head of a key that is equipped with a transponder chip may be removed to reveal a steel L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage procedure. It involves cutting the keys precisely and programming the chip to make it sync with the vehicle immobiliser.

A transponder is a device with Non-Volatile Memory. It has a set windings, which are very fine wires that are wrapped around the tube. They look similar to 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 types of transponder chips, the first is called the 80-bit and the other is called the circle + (General Motors). The first can be reused, but has to be removed using a special machine in order to work on a different vehicle compatible with it. The latter type is more difficult as the old keys are usually broken and drilled or thrown away when key cases are replaced. However they can be used with a service-key that does not require batteries.

Immobiliser Systems

An immobiliser system is an electronic security measure that deters thieves from starting your vehicle. It works by sending a signal from the vehicle to your key when you attempt to start it. The electronic chip inside the key responds by transmitting a unique code that must match that of the vehicle in order for it to start. If the codes don't match, the engine will stop immediately and prevent theft of your vehicle.


Modern smart keys and fobs have an embedded transponder, which stores electronic security information in a format that can't be copied easily. When the fob or key are inserted into the ignition, they send this code to the ECU. The ECU is then able to compare it with the code that is stored in its memory and activates the fuel system and ignition circuit if they coincide. If the codes don't match and the engine does not start even if the ignition circuit is short-circuited by a thief.

Replacing a key or fob is a multi-stage process that involves accurate cutting of the new key blade, and programming it to connect with the immobiliser system of your vehicle. Each immobiliser is unique and has its own unique programming procedure. We utilize Ross-Tech to ensure that the replacement key is correctly programmed.
