The fob can be removed to reveal an indentation that is circular for the metal key, pop the battery out (using the paperclip) and then insert the new battery, making sure that it's pointing the right way up. Then clip the inside of the key back together.

Remotes

Replacing the Lexus remote or fob can be an extremely complex process that requires skilled locksmiths equipped with the right tools and expertise. Some models require that the transponder chip within the key be reprogrammed in order to work with the immobiliser system of the car. The lexus key fob replacement models employ different methods to program these chips. This is accomplished by using a specific device that sends a code chip to unlock the doors or start the engine.

Certain Lexus cars are equipped with a single unit that includes the key head and the remote, and these are more simple to replace since no separate chip is required. This type of key can also be a bit less expensive.

Whatever the type of key regardless of the type of key, all fobs eventually run out of battery power.

Transponder Chips

The majority of new cars built since 1995 have transponder chips inside the key head to disable the immobiliser system. The head of a key which contains a transponder chip is able to be removed to reveal a metal L-shaped key. A transponder chip replacement key or fob is a multi-stage procedure. It involves cutting the keys with precision and programming the chip to sync up with the vehicle immobiliser.

Transponders are chips that has Non-Volatile Memory. It is comprised of a set of windings, which are fine wires coiled around the tube. They look like those in an electric motor. These windings create a coded message that the car can read. If the code is correct it will allow the car to start.

There are two types of transponder chips. One is called the 80 bit and the other is known as a circle + (General Motors). The former is reusable but must be delocked with a special device to be used in a compatible vehicle. The second kind is more difficult to use because the old ones can be broken, drilled, or toss out when keycases are changed. They can be salvaged, however, to use with a service key that doesn't require batteries to function.

Immobiliser Systems

An immobiliser system is a digital security device that prevents thieves from starting your car. It operates by sending an electronic signal from your car to the key every time you attempt to start it. The electronic chip inside your key then responds with a unique code which must match the one found in the vehicle to start. If the codes don't match, your engine will immediately shut down to stop theft.

Modern smart keys and fobs are equipped with embedded transponder chips that stores security information in a format that cannot be easily duplicated. When the fob or key is inserted into the ignition, they send this code to the ECU. The ECU then compares it to the code in its memory and then activates the ignition and fuel system circuit if they match. If the codes do not match the engine won't start, even when the ignition circuit is short-circuited by a burglar.
