Remotes

Replacing the Lexus remote or fob can be difficult and requires skilled locksmiths who have the right tools as well as knowledge. Certain models require the transponder on the key to be programmed to work with the immobiliser of the vehicle. The Lexus models employ different methods to program these chips. This is accomplished using a specific device that sends a code chip to unlock the doors or to start the engine.

Certain Lexus vehicles are designed with a key head that is a combination of the key head and remote. These are easier to replace, as there is no separate chip to replace. This kind of key could also be a bit cheaper.

No matter what type of key regardless of the type of key, all fobs eventually run out of battery power.

Transponder Chips

More or less all new cars built since 1995 have transponder chips within the key head to disarm the immobiliser system. The head of a key which includes a transponder chips can be removed to reveal a metallic L-shaped key. A transponder-chip replacement key or fob is a multistage process. It involves cutting keys precisely and programming the chip to make it sync with the vehicle immobiliser.

A transponder is a chip with Non-Volatile Memory. It is comprised of a set of windings which are fine wires wrapped around a tube. They resemble the ones in an electric motor. These windings create a coded message that the car will read. If the code is correct the car will begin to move.

There are two types of transponder chips. One called the 80 bit and the other known as a circle + (General Motors). The first is reusable but it needs to be unlocked by a specific machine in order to work in another compatible vehicle. The second one is more difficult to use as the older ones could be broken, drilled or thrown out when key cases are changed. However they can be used with a service-key which doesn't require a battery.

Immobiliser Systems

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

Modern smart keys and fobs contain an embedded transponder that can store electronic security information in a format that can't be copied easily. When the key or fob is inserted into the ignition, they send this code to the ECU. The ECU analyzes this code in comparison to the one in its memory, and activates both the fuel system and the ignition circuit if they match. If the codes do not match, your engine won't start - even if a burglar tries to short-circuit the ignition circuit.

Replacing a lost or damaged key is a multi-stage procedure that involves accurate cutting of the new blade for the key and programming it to connect with the immobiliser system of your vehicle. There are many different immobilisers that are available in various models and years and each one requires an individual programming procedure.
