Keys

Lexus keys aren't simple to replace and require a specialist locksmith for replacing car keys to create a spare working. Every Lexus key has an embedded microchip that must be programmed in order to sync with the immobiliser system of your vehicle.

On the side of the fob you will see two or more screws remove them and place them somewhere safe (they're small and can be lost). Remove the fob, revealing an indentation that is circular where the metal key will be.

Remotes

lexus key cutting remotes and fobs can be difficult to replace and require locksmiths who are knowledgeable and have the right tools. Certain models require that the transponder chip contained in the key be reprogrammed to function with the car's immobiliser system. The chips are programmed using different methods, based on the model of Lexus. This is accomplished making use of a special device that transmits a code to the chip to unlock the doors or start the engine.

Certain duplicate lexus key vehicles are designed with a unit that combines the key head and remote. They are easy to replace, as there is no chip that needs to be replaced. This kind of key could also be a little less expensive.

Transponder Chips

Transponder chips are found in the keys of nearly all new cars produced since 1995. They can be used to disarm immobiliser systems. The head of a key that contains a transponder chip is able to be removed to reveal a steel L-shaped key. Making a replacement key, or fob that is made using a transponder chip is a multi-stage process which includes accurate cutting of the replacement keys and programming of the transponder chip to synch up with the vehicle's immobiliser.

Transponders are chips that has Non-Volatile Memory. It has a set windings, which are very fine wires wrapped around the tube. They resemble the ones in an electric motor. These windings form a coded signal that the car can read. If the code is correct the car will start.

There are two kinds of transponder chip. The one is known as the 80-bit and the second is called the circle + (General Motors). The first is reusable but it needs to be unlocked by a machine that is specially designed to function in a compatible vehicle. The latter is a bit more difficult, as the older ones are often broken and then drilled through or discarded after key cases are replaced. They can be salvaged, however, to use with the service key, which doesn't require a battery in order to operate.

Immobiliser Systems

An immobiliser system is a digital security device that deters thieves from starting your vehicle. It works by sending a signal from the vehicle to the 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 to allow it to start. If the codes do not match, your engine will shut off immediately to stop theft.

Modern smart keys and fobs come with an embedded transponder which stores electronic security information in a format that cannot be easily copied. When your fob or key is placed in the ignition, it transmits this code to a receiver in the ECU. The ECU is then able to compare it with the code stored in its memory. It then activates the ignition and fuel system circuit if they match. If the codes don't match the engine won't start even in the event that the ignition circuit is short-circuited by a burglar.

Replacing a key or fob is a multi-stage process that involves accurate cutting of the new blade of the key and programming it to synch with your car's immobiliser system. Each immobiliser is unique and has its own unique programming procedure.
