Remotes

Replacing a Lexus remote or fob can be complicated and requires skilled locksmiths who have the right tools and expertise. Some models require the transponder within the key to be programmed so that it can work with the immobiliser of the vehicle. The Lexus models employ different methods to program these chips. This is done by using a special device which transmits a code to the chip to unlock the doors or to start the engine.

Certain Lexus cars are designed with a system that combines the key head and the remote. They are easy to replace, as there is no separate chip needed. This kind of key is also a bit less expensive.

All fobs eventually lose battery power, regardless of the kind of key. This could be a difficult experience, but it is possible to get your lexus key maker back up and running with a bit of know-how.

Insert the coin (20p works well) into the hole and twist. This should reveal a flat area that you can make use of a paper clip to take away.

Then, pull the old battery off and insert the new one. Make sure the new battery is in the correct direction of operation. Finally, clip the inside of the fob back together, and insert the key back into the metal.

Transponder Chips

Most new cars manufactured after 1995 have transponder chips in the key head to disable the immobiliser system. If you've got a key with a chip, the head comes with a cover which can be pulled off to reveal an L-shaped key. A transponder-chip replacement keys or fob is a multi-stage procedure. It involves cutting the keys accurately and programming the chip to connect with the vehicle immobiliser.

A transponder is an electronic chip that has Non-Volatile Memory (NVM) that houses a set of windings (very fine wire coiled around the tube) that resemble ones in an electric motor. These windings create a coded message that the car is able to read. If the code is correct, the car will start.

There are two types of transponder chip, the first is called the 80-bit, while the second is known as the circle + (General Motors). The first is reusable but needs to be unlocked by a special machine to function in a compatible vehicle. The latter is more difficult since the earlier ones are often broken, drilled through or discarded when key cases are replaced. They can be salvaged however for use with the service key, which doesn't require batteries to function.

Immobiliser Systems

Immobiliser systems are electronic security devices that stop thieves from starting up your car. It operates by sending an electronic signal from the vehicle to the key whenever you attempt to start it. The chip inside the key responds by sending a unique code which must match that of the vehicle to allow 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 are equipped with embedded transponder chips that stores security information in a format that cannot be easily duplicated. When the fob or key are inserted in 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 ignition system and fuel circuit if the two match. If the codes do not match, the engine will not start, even if a thief tries to short-circuit the ignition circuit.

The replacement of the fob or key involves an entire process that involves cutting the new key blade precisely and programming it so that it is compatible with your car's security system. Each immobiliser system is distinct and has its own unique programming procedure. We employ Ross-Tech to ensure that the replacement key is correctly programmed.
