Keys

Lexus keys are not simple to replace and require a professional locksmith to replace your car key to make a working spare. This is because each Lexus key contains an electronic chip that needs to be programmed in order to synchronise with your vehicle's immobiliser in case it does not. If it doesn't, the vehicle will not start.

This process takes time and requires special equipment to perform correctly, and every model has a distinct procedure for programming. Replacing remotes or keys is a pricey task that you should leave to professionals, unless equipped with the right tools and knowledge.

You will need to replace the batteries in your smart or conventional key. Both keys function by turning the barrel of the ignition. This can be done by yourself, but you will need an inexpensive Phillips Screwdriver, a coin worth 20p and a paperclip. On the back of the fob you will see one or two screws take them off and place them in a safe location (they're small and easily lost). The fob is removed, revealing an indentation with a circular pattern where the key's metal part will be. The battery can be removed using the paperclip and insert the new battery, making sure that it is inserted correctly. Then clip the inside of the key back to the fob.

Remotes

Replacing a lexus smart key replacement remote or fob is complicated and requires skilled locksmiths who have the right tools and knowledge. Some models require the transponder on the key to be reprogrammed in order to function with the immobiliser system in the car. These chips are programmed using different methods, based on the model of Lexus. This is accomplished making use of a special device that sends a code to the chip to unlock the doors or start the engine.

Some Lexus cars are equipped with a single piece of hardware that incorporates the key head and the remote. They are easier to replace since there is no separate chip. This kind of key is also a bit cheaper.

Whatever the type of key, all fobs eventually run out of battery power. It can be quite frustrating however with a bit of knowledge you can get your lexus replacement keys up and running again. Start by reading the owner's manual to identify the type of battery you need and find an alternative. Find a small hole in the inside of the fob, and insert coins (a 20p piece works best) and twist. You should be able to see a flat area which you can easily remove using a paperclip.

Then, take out the old battery and replace it with the new one. Be sure to insert the battery in the proper orientation. Finally, cut the inside of the fob back and re-insert the metal key.

Transponder Chips

More or less all new cars built since 1995 have transponder chips in the key head to disarm the immobiliser system. If you have a key that has a chip inside it, the head is covered with a plastic cover that can be pulled off to reveal an L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting keys precisely and programming the chip to connect with the vehicle's immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that contains a set of windings (very fine wire that is wrapped around the tube) that resemble ones found in an electric motor. The windings are coded to create a signal that the car can read. If the code is correct, then the car will allow you to start it.

There are two types of transponder chip. The first is called the 80-bit and the second is known as the circle + (General Motors). The former can be reused but it needs to be unlocked by a specific machine in order to work in another compatible vehicle. The second is more difficult to use as the old ones can be broken, drilled or taken away when key cases are changed. They can be salvaged however and then used to create an ad-hoc key that doesn't require batteries to function.

Immobiliser Systems

An immobiliser system is an electronic security measure that deters thieves from starting your car. It works by sending an electronic signal from the vehicle to the 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 do not match, the engine will shut off immediately to stop theft.

Modern smart keys and fobs come with an embedded transponder chip that stores security information in a format that can't be duplicated. When the fob or key is inserted into the ignition, they send this code to 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 they coincide. If the codes do not match then the engine will not start even in the event that the ignition circuit is cut off by a criminal.

Replacing a fob or a key is a multi-stage procedure that requires precise cutting of the new key blade, and programming it to connect with the immobiliser system of your vehicle. There are a variety of immobiliser systems that are used in different years and models and each needs its own distinct programming process. We employ Ross-Tech to ensure that the replacement key is correctly programmed. This will ensure the best performance and security.
