Replacing remotes or keys is a pricey task that should be left to professionals unless you are equipped with the proper tools and expertise.

Remove the fob and you will see an indentation with a circular shape that houses the key made from metal, take the battery out (using the paperclip) and insert the new one making sure that it's pointing the right way up. Clip the inside of the metal key back together.

Remotes

Replacing the Lexus remote or fob is a complicated process and requires skilled locksmiths who have the right tools and experience. Some models require the transponder inside the key to be programmed to allow it to communicate with the immobiliser system of the car. These chips are programmed using different methods, based on the model of Lost Lexus Keys. This is done with an electronic device that transmits an electrical signal to the chip that matches the code used to unlock the doors and start the engine.

Certain Lexus cars are equipped with a single unit that includes the key head as well as the remote. They are simpler to replace as no separate chip is required. This kind of key may also be a little cheaper.

Regardless of the key type any fob eventually runs out of battery power. This is a stressful experience, but it is possible to get your Lexus back up and running with a little knowledge.

Transponder Chips

Most new cars built since 1995 have transponder chips in the key head that allow it to deactivate the immobiliser system. If you've got keys that has a chip inside it, the head is covered with a plastic cover that can be taken off to reveal an L-shaped metal key. The process of getting a replacement key fob that is made using transponder chips is a multi-stage process which involves precise cutting of replacement keys and programming of the transponder chip so that it can synch up with the vehicle's immobiliser system.

A transponder is a device that has Non-Volatile Memory. It contains a set windings, which are fine wires coiled around a tube. They look like those 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 types of transponder chip. The one is known as the 80-bit and the other is called the circle + (General Motors). The first type 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 because the previous ones are often broken or drilled through, or thrown away when key cases are replaced. However, they can be used with a key-service that doesn't require a battery.

Immobiliser Systems

Immobiliser systems are electronic security measures which prevent thieves from starting your car. It works by sending an electronic signal from the vehicle to your key each time you attempt to start it. The electronic chip in the key responds by sending a unique code that must match that of the vehicle in order for 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 contain an embedded transponder which stores electronic security information in a format that can't be copied easily. When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU is then able to compare it with the code in its memory and activates the fuel system and ignition circuit if they coincide. If the codes don't match and the engine does not start, even in the event that the ignition circuit is short-circuited by a thief.

The procedure of replacing the fob or key involves an entire process that involves cutting the new key blade precisely and programming it so that it syncs with your car's system. There are a variety of immobilisers that are available in various models and years, and each requires its own unique programming procedure.
