Keys

Lexus keys aren't easy to replace and require a professional locksmith for replacing car keys to create a spare working. Every Lexus key is equipped with an embedded microchip, which needs to be programmed to sync with the immobiliser system in your vehicle.

Then, you can clip the inside of the key back together.

Remotes

Lexus remotes and fobs aren't easy to replace and require locksmiths who are both knowledgeable and have the right tools. Some models require the transponder within the key to be programmed to work with the immobiliser system of the car. The Lexus models employ different methods to program these chips. This is done using an instrument that sends an electrical signal to the chip that matches the code used to open the doors and start the engine.

Some Lexus cars are designed with a single piece of hardware which includes the key head and remote. These are simpler to replace as there is no separate chip. This kind of key is also less expensive.

Transponder Chips

Transponder chips are present in the key heads of a majority of new vehicles manufactured after 1995. They are used to disable immobiliser systems. The head of a key that has a transponder chip can be removed to reveal a steel L-shaped key. A replacement key or fob made of a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys as well as programming the transponder chip to link up with the vehicle's immobiliser.

Transponders are chips that has Non-Volatile Memory. It contains a set windings which are fine wires coiled around a tube. They look similar to those in an electric motor. These windings produce a coded message that the car can read. If the code is correct then the car will allow you to start it.

There are two types of transponder chips, one known as the 80 bit, and the other referred to as a circle + (General Motors). The first is reusable, but it must be unlocked with a special machine in order to work in a different vehicle that is compatible. The latter is more difficult since the earlier keys are usually damaged and drilled or thrown away when key cases are replaced. However, they can be utilized with a service key that does not require batteries.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology that deters thieves from starting your car. It operates by sending an electronic signal from your car to your key each time you try to start it. The electronic chip inside the key responds with an unique code that must match that in the vehicle in order to start. If the codes don't match, your engine will shut off immediately to stop theft.

Modern smart keys and fobs feature an embedded transponder chip that stores electronic security in a format that cannot be easily duplicated. When your fob or key is inserted into the ignition, it transmits this code to a device within the ECU. The ECU analyzes this code in comparison to the one that is stored in its memory, and then activates both the fuel system and the ignition circuit if they match. If the codes do not match, the engine will not start, even when the ignition circuit is damaged by a thief.

The procedure of replacing the fob or key requires a multi-stage process that includes cutting the new blade precisely and programming it to ensure that it works with your car's security system. Each immobiliser is unique and has its own programming procedure. We use Ross-Tech to ensure that the replacement key is correctly programmed. This will ensure maximum performance and security.
