Remotes
Lexus remotes and fobs aren't easy to replace and require locksmiths who are knowledgeable and have the right tools. Some models require that the transponder chip within the key be changed in order to work with the vehicle's immobiliser system. The Lexus models employ different methods to program these chips. This is done using a specific device that sends a code chip to unlock the doors or to start the engine.
Some Lexus cars are designed with a single unit that consists of the key head and the remote, and these are simpler to replace as no separate chip is required. This kind of key could also be a little less expensive.

Transponder Chips
Transponder chips can be found in key heads of almost all new cars manufactured since 1995. They can be used to disable immobiliser systems. If you have a key with a chip, the head is covered with a plastic cover that is able to be pulled off to reveal an L-shaped key. The process of getting a replacement key fob with a transponder chip is a multi-stage process which involves precise cutting of replacement keys and programming the transponder chip in order to synch up with the vehicle's immobiliser system.
A transponder is a device with Non-Volatile Memory. It contains a set windings which are fine wires coiled around a tube. They resemble the ones in an electric motor. The windings create a coded signal that the car can read. If the code is valid, then the car will allow you to start it up.
There are two kinds of transponder chip, the one is known as the 80-bit and the other is known as the circle + (General Motors). The former type is reusable but must be delocked by a special machine to function in a different compatible vehicle. The latter one is more difficult, as the older keys are often damaged and drilled or thrown away when key cases are replaced. However, they can be used with a service-key that does not require a battery.
Immobiliser Systems
Immobiliser systems are electronic security measures which prevent thieves from starting your vehicle. It operates by sending a signal from the vehicle to the key when you attempt to start it. The chip inside 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, the engine will stop immediately, and stop theft of your vehicle.
Modern smart keys and fobs have an embedded transponder that can store electronic security information in a format which cannot be easily copied. When your fob or key is installed in the ignition it transmits this code to a device within the ECU. The ECU compares this code with the one stored in its memory, and activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine will not start, even in the event that the ignition circuit is short-circuited by a thief.
The process of replacing a key or fob involves an entire process that involves cutting the new blade precisely and programming it to ensure that it is compatible with your car's system. There are many different immobilisers used in different models and years and each has an individual programming procedure. We use Ross-Tech software to ensure that your replacement key is programmed correctly to ensure optimum performance and maximum security.
