Keys

Lexus keys are not simple to replace and require a professional locksmith to replace your car key to create a working spare. This is due to the fact that every lost lexus key key is equipped with an electronic chip that needs to be programmed to synchronise with your vehicle's immobiliser system If it is not, the car will not be able to start.

It takes a lot time and specialized equipment for this procedure to be executed correctly. Each model has its own specific programming process. Replacing remotes or keys is a pricey task that you should leave to professionals, unless equipped with the proper tools and knowledge.

You will have to replace the batteries in your smart key or standard key. Both keys operate by turning the barrel of the ignition. This can be done by yourself but you'll need an inexpensive Phillips Screwdriver, 20p coin and paperclip. There are one or two screws on the back of the fob of the key. Unscrew them, and then store them in a safe place (they are small and easy to lose). Take the fob off to reveal a circular indentation for the metal key, pop the battery out (using the paperclip) and then put in the new one ensuring it's the correct way up. Clip the the metal key back together.

Remotes

Lexus remotes and fobs aren't easy to replace and require locksmiths who are skilled and possess the appropriate tools. Certain models require that the chip inside the key be changed in order to work with the car's immobiliser system. These chips are programmed by different methods based on the model of Lexus. This is done with a special device that sends an indication to the chip which matches the code used to open the doors and start the engine.

Some Lexus automobiles are built with a single piece of hardware that includes the key head and the remote. They are more simple to replace since there is no separate chip. This kind of key is also less expensive.

All fobs eventually lose their battery power, no matter the kind of key. It can be very frustrating however with a little know-how you can get your Lexus back in operation. First, check the owner's manual to identify the type of battery you need and find an alternative. Find a small opening on the inside of your fob. Insert an amount of money (20p is a good choice) into the hole and then twist. The fob should be revealed as an unflattened area that you can make use of a paper clip to remove.

Then, take the old battery away and then insert the new one. Make sure that you insert the battery with the proper orientation. Clip the two sides of your fob to insert the key metal.

Transponder Chips

Transponder chips are found in the head of the key on almost all new cars built since 1995. They are used to disable immobiliser systems. The head of a key which is equipped with a transponder chip may be removed to reveal a steel L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage procedure. It involves cutting keys precisely and programming the chip to connect with the vehicle's immobiliser.

Transponders are electronic chip with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire that is wrapped around tubes) that look like the ones 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 chip, one known as the 80 bit, and the other referred to as a circle + (General Motors). The first kind is reusable, but must be unlocked using a special machine in order to work in a different vehicle that is compatible. The latter is a bit more difficult since the earlier ones are often broken, drilled through or thrown away when key cases are replaced. However they can be utilized with a service key that doesn't require a battery.

Immobiliser Systems

An immobiliser is a digital security device which prevents thieves from opening your vehicle. It works by sending an electronic signal from the car to the key each time you try to start it. The chip inside the key responds by sending a unique code which must match the one of the vehicle to allow it to start. If the codes do not match, your engine will stop immediately to stop theft.

Modern smart keys and fobs come with embedded transponder chips that stores electronic security in a format that cannot be duplicated. When your fob or key is inserted into the ignition, it transmits the code to a receiver within the ECU. The ECU analyzes this code in comparison to the one that is stored in its memory and activates the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine will not start - even if someone tries to short-circuit the ignition circuit.

Replacing a key or fob is a multi-stage procedure which involves precise cutting the new blade of the key and programming it to communicate with the immobiliser system of your vehicle. Each immobiliser system is unique and has its own programming procedure.
