Keys

Lexus keys aren't simple to replace and require a professional locksmith to replace your car key to make a functioning spare. Each lexus key replacement key has an embedded microchip that must be programmed to connect with the immobiliser system of your vehicle.

It requires a lot of time and equipment that is specially designed for this process to be carried out correctly. Each model has its own specific programming process.

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

Remotes

Replacing a Lexus remote or fob is a complicated process and requires skilled locksmiths who have the right tools and experience. Some models require that the transponder chip contained in the key be programmed in order to work with the immobiliser system of the car. The Lexus models use different methods to program these chips. This is done by using a special device that transmits a code to the chip to unlock the doors or to start the engine.

Certain Lexus cars are constructed with a single piece of hardware that incorporates the key head and remote. They are more simple to replace since no separate chip is required. This type of key can also be a little less expensive.

All fobs eventually lose battery power, no matter the type of key. It can be a frustrating experience but with a little bit of knowledge you can get your Lexus up and running.

Transponder Chips

Transponder chips are in the key heads of a majority of new vehicles manufactured after 1995. They are used to disarm immobiliser systems. The head of a key which contains a transponder chip is able to be removed to reveal a steel L-shaped key. Having a replacement key or fob that is made using transponder chips is a multi-stage procedure that includes precise cutting of the replacement keys and programming of the transponder chip in order to synch up with the vehicle's immobiliser system.

A transponder is an electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire twisted around the tube) that look like the ones in an electric motor. These windings generate a signal that the car can read. If the code is correct the car will start.

There are two types of transponder chips, the first is called the 80-bit, while the second is called the circle + (General Motors). The former can be reused but needs to be unlocked by a machine that is specially designed to function in a different compatible vehicle. The second one is more difficult to use because the older keys could be broken, drilled or thrown out when key cases are changed. However, they can be used with a service-key that does not require batteries.

Immobiliser Systems

An immobiliser is an electronic security feature that deters thieves from starting your car. It operates by sending an electronic signal from the vehicle to the key every time you try to start it. The electronic chip inside the key responds by transmitting a unique code that must match that of the vehicle in order for it to start. If the codes do not match, your engine will shut off immediately to stop theft.

Modern smart keys and fobs come with embedded transponder chips that stores electronic security in a format that cannot be easily duplicated. When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU analyzes this code in comparison to the one in its memory, and then activates the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine will not start, even if the ignition circuit is short-circuited by a burglar.

The replacement of the fob or key involves a multi-stage procedure that includes cutting the new blade precisely and programming it so that it works with the car's system. There are many different immobilisers that are available in various models and years and each needs its own unique programming procedure. We employ Ross-Tech to ensure that the replacement key is programmed correctly. This will give you maximum performance and security.
