Keys

Lexus keys aren't always easy to replace. A specialist locksmith is required to design an appropriate replacement that functions. This is because every Lexus key is equipped with an electronic chip that needs to be programmed to sync with the immobiliser of your vehicle - if not it will not start.

This process takes time and specialized equipment to complete correctly, and every model has a distinct programing procedure. Replacing a key or a remote fob can be a costly task and one you should leave to experts unless you have the right tools and know-how.

You can save money by doing it yourself but it will require the use of a small Phillips screwdriver as well as coins (a 20p piece works best) and a paperclip. On the side of the fob you will see two or more screws take them off and place them in a secure place (they're tiny and easy to lose). Remove the fob to reveal an indentation with a circular shape that houses the key made of metal. Take the battery out (using the paperclip) and then put in the new lexus key cost battery, making sure it's facing the right way up. Clip the inside of the metal key back together.

Remotes

Replacing the Lexus remote or fob can be complicated and requires skilled locksmiths with the right tools and knowledge. Certain models require that the transponder chip within the key be changed in order to work with the vehicle's immobiliser system. The Lexus models use different methods to program these chips. This is done by using an instrument that sends an electrical signal to the chip that matches the code used to open the doors and start the engine.

Some Lexus vehicles are designed with a unit that combines the key head and remote. These are easier to replace since there is no chip that needs to be replaced. This kind of key is also a bit less expensive.

All fobs eventually lose battery power, no matter the type of key. This is a stressful experience, but it is possible to get your lexus key cut back to normal with a little knowledge.

Then, find a small hole in the inside of the fob. insert an item of currency (a 20p piece works best) and twist. This should reveal a flat area that you can employ a paperclip to take away.

Next, pop the old battery out and insert the new one. Make sure that you insert the battery with the proper direction of operation. Finally, cut the inside of the fob back together, and re-insert the metal key.

Transponder Chips

More or less all new cars built since 1995 have transponder chips embedded in the key head to disable the immobiliser system. The head of a key which has a transponder chip can be removed to reveal a steel L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting the keys precisely and programming the chip to communicate with the vehicle immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that contains a set of windings (very fine wire coiled around the tube) which look similar to ones found in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct the car will start.

There are two types of transponder chips. One is called the 80 bit and the other known as a circle + (General Motors). The first is reusable, but it must be unlocked with a special machine to function on a different vehicle compatible with it. The second type is more difficult to use as the old ones can be broken, drilled, or removed when key cases are changed. They can be salvaged however and used with a service key that doesn't require batteries to function.

Immobiliser Systems

Immobiliser systems are electronic security measures which prevent thieves from starting up your vehicle. It operates by sending an electronic signal from your car to the key each time you attempt to start it. The electronic chip in the key responds by sending a unique code which must match the one of the vehicle to allow it to start. If the codes do not coincide, your engine will immediately shut down to stop theft.

Modern smart keys and fobs are equipped with an embedded transponder that stores electronic security information in a format that is not easily copied. When the key or fob are placed in the ignition, they send this code to the ECU. The ECU is then able to compare it with the code stored in its memory and then activates the fuel system and ignition circuit if they match. If the codes do not match and the engine does not start even in the event that the ignition circuit is damaged by a thief.

The procedure of replacing the fob or key involves a multi-stage procedure that includes cutting the new blade accurately and programming it so that it syncs with the car's system. Each immobiliser system is distinct and has its own unique programming procedure. We use Ross-Tech to ensure that the replacement key is programmed correctly. This will provide you with the highest performance and security.
