It is simple to replace it with the help of a paperclip. Simply take out the battery that was in use, and then insert the new one (refer to the owner's manual for the type of battery you require) and then secure it back in the correct position.

Keys

Lexus keys can be difficult to replace. A specialist locksmith is needed to make a spare that works. Each Lexus key comes with a microchip that needs to be programmed to connect with the immobiliser system of your vehicle.

This process takes time and special equipment to do correctly, and every model has its own unique procedure for programming. Replacing a key or remote fob is a costly job and should be left to professionals unless you possess the right tools and know-how.

If you have a traditional key that turns on the ignition barrel, or a smart key that starts the car at the push of a button, both will eventually need their batteries replaced. You can save money by doing it yourself, but it will require an inexpensive Phillips screwdriver, an old coin (a 20p piece works well) and a paperclip. On the side of the fob you will see two or more screws take them off and place them in a safe location (they're small and easy to lose). Take the fob off, revealing a circular indentation where the key's metal part will be. The battery can be removed with the paperclip, and then insert the new battery, making sure that it's inserted correctly. Then, clip the inside of the key back together.

Remotes

Lexus remotes and fobs can be difficult to replace and require locksmiths who are well-versed and have the proper tools. Certain models require the transponder inside the key to be changed so that it can work with the immobiliser system of the car. The Lexus models employ different methods to program these chips. This is accomplished using a special device which transmits a code to the chip to unlock the doors or start the engine.


Certain Lexus vehicles are equipped with a unit that combines the key head and remote. They are much easier to replace since there is no chip that needs to be replaced. This kind of key is also a bit cheaper.

Transponder Chips

The majority of new cars built since 1995 have transponder chips in the head of the key to disable the immobiliser system. The head of a key that 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 communicate with the vehicle's immobiliser.

A transponder is a type of chip that has Non-Volatile Memory. It is comprised of a set of windings that are fine wires that are wrapped around the tube. They resemble the ones in an electric motor. The windings generate a coded message that the car will read. If the code is correct the car will start.

There are two kinds of transponder chips. The one is known as the 80-bit and the other is called the circle + (General Motors). The first type is reusable, but it must be removed using a special machine in order to work on a vehicle that is compatible with the. The second type is more difficult to use due to the fact that the older keys could be damaged, drilled or toss out when keycases are changed. They can be salvaged, however for use with a service key that doesn't need a battery to operate.

Immobiliser Systems

An immobiliser is an electronic security measure which prevents thieves from opening your vehicle. It works by sending an electronic signal from the vehicle to your key each time you try to start it. The electronic chip inside the key responds by sending a unique number of codes that must match that of the vehicle to allow it to start. If the codes don't match, the engine will shut down immediately to stop theft.

Modern smart keys and fobs come with an embedded transponder that stores electronic security information in a format that can't be copied easily. When the fob or key are inserted into the ignition, they transmit this code to the ECU. The ECU then compares it with the code stored in its memory, and activates the ignition and fuel system circuit if the two coincide. If the codes don't match, your engine won't start - even if a burglar tries to short-circuit the ignition circuit.

Replacing a key or fob 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 that are available in various years and models, and each requires an individual programming procedure.
