Remotes
Lexus remotes and fobs can be difficult to replace and require locksmiths who are both well-versed and have the proper tools. Some models require that the transponder chip within the key be programmed in order to work with the car's immobiliser system. The chips are programmed with different methods, based on the model of Lexus. replacement lexus key www.g28carkeys.co.uk is accomplished by using a special device that sends a signal to the chip which matches the code used to open the doors and start the engine.
Some Lexus vehicles are designed with a key head that is a combination of the key head and remote. These are easier to replace because there is no chip that needs to be replaced. This kind of key is also a bit cheaper.

Transponder Chips
Transponder chips are in the keys of nearly all new cars produced since 1995. They can be used to disable immobiliser systems. The head of a key which contains a transponder chip is able to be removed to reveal a metallic L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting the keys with precision and programming the chip to make it sync with the vehicle immobiliser.
A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire coiled around the tube) that look like the ones found in an electric motor. These windings form a coded signal for the car to read. If the code is correct it will allow the car to start.
There are two types of transponder chips. One is known as the 80 bit, and the other one is called a circle + (General Motors). The first can be reused, but has to be removed using a special machine in order to work in a different vehicle that is compatible. The second type is more difficult to use due to the fact that the older ones could be broken, drilled or taken away when key cases are changed. However, they can be used with a key-service that does not require a battery.
Immobiliser Systems
An immobiliser system is an electronic security measure that prevents thieves from starting your vehicle. It operates by sending a signal from your car to the key when you attempt to start it. The electronic chip in the key responds by sending a unique code that must match the one of the vehicle to allow it to start. If the codes don't match, your engine will shut down immediately to stop theft.
Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format that cannot be easily copied. When the fob or key is inserted into the ignition, they send this code to the ECU. The ECU is then able to compare it with the code in its memory and activates the fuel system and ignition circuit if they coincide. If the codes do not match, your engine will not start - even if a burglar tries to short-circuit the ignition circuit.
Replacing a lost or damaged key is a multi-stage process that involves precise cutting of the new key blade and programming it to communicate with the immobiliser system of your vehicle. There are many different immobilisers used in different years and models and each has an individual programming procedure.
