It's simple to replace it using the help of a paperclip. Simply take out the battery that was in use, and then insert the new battery (refer to the owner's manual for the type of battery that you require), then clip it back into the appropriate spot.

Keys

Lexus keys are not simple to replace and require a professional car key replacement locksmith to create a working spare. Each Lexus key is equipped with a microchip which must be programmed to communicate with the immobiliser system in your vehicle.

It takes a lot time and special equipment for this process to be carried out correctly. Each model has its own procedure for programming. Replacing keys or remotes is a pricey task that should be left to experts, unless equipped with the proper tools and know-how.

Remotes

Replacing a Lexus remote or fob is an extremely complex process that requires skilled locksmiths equipped with the right tools as well as knowledge. Some models require that the transponder chip in the key be reprogrammed to function with the car's immobiliser system. These chips are programmed using different methods, based on the model of Lexus. This is done using a special device that sends an electrical signal to the chip that is compatible with the code used to open the doors and start the engine.


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

Transponder Chips

Transponder chips can be found in key heads of almost all new cars manufactured since 1995. They are used to disarm immobiliser systems. The head of a key that is equipped with a transponder chip may be removed to reveal a metal L-shaped key. A transponder-chip replacement key, also known as a fob is a multistage process. It involves cutting the keys precisely and programming the chip to connect with the vehicle immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire wrapped around the tube) which look similar to ones in an electric motor. These windings form a coded signal that the car can read. If the code is correct, the car will start.

There are two types of transponder chip. The first is called the 80-bit and the other is known as the circle + (General Motors). The first one can be reused, but has to be unlocked with a special machine to function on a different vehicle compatible with it. The latter is a bit more difficult since the earlier keys are usually broken and then drilled through or thrown away when key cases are replaced. However they can be used with a service-key which does not require a battery.

Immobiliser Systems

Immobiliser systems are electronic security devices that prevent thieves from starting up your car. It operates by sending a signal from the vehicle 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 in order for it to start. If the codes aren't compatible, the engine will stop immediately, and stop theft of your vehicle.

Modern smart keys and fobs contain an embedded transponder, which stores electronic security information in a format which cannot be easily copied. When your fob or key is put into the ignition, it transmits the code to a receiver within the ECU. The ECU then compares it with the code that is stored in its memory and activates the fuel system and ignition circuit if the two coincide. If the codes don't match, the engine will not start, even if a burglar tries to short-circuit the ignition circuit.

Replacing a key or fob is a multi-stage process which involves precise cutting the new key blade, and programming it to communicate with your car's immobiliser system. There are many different immobilisers that are available in various models and years, and each requires the use of a unique programming method.
