Replacing it is easy with using a paperclip. Pop the battery that is in use, insert the new one (refer to the owner's guide to see which type of battery you need) and then clip it back in place.

Keys

Lexus keys are not easy to replace and require a specialist locksmith for car keys to make a functioning spare. Every Lexus key comes with an embedded microchip that must be programmed to communicate with the immobiliser system of your vehicle.

You can save money by doing it yourself, but it will require a small Phillips screwdriver and the coin (a 20p piece works best) and a paperclip. You will find two or three screws on the back of the key fob. Remove them and store them securely (they are small and easy to lose). The fob can be removed to reveal an indentation of circular shape for the metal key, pop the battery out (using the paperclip) and then insert the new one, making sure it's facing the right way up. Clip the the metal key back together.

Remotes

Replacing a lexus key replacement near me remote or fob can be difficult and requires skilled locksmiths equipped with the right tools as well as knowledge. Some models require the transponder inside the key to be programmed to allow it to communicate with the immobiliser systems of the car. These chips are programmed by different methods based on the model of lexus car key. This is done with a special device that sends an electrical signal to the chip that is compatible with the code used to open the doors and start the engine.

Some Lexus cars are designed with a key head that is a combination of the key head and the remote. They are simpler to replace, since there is no chip that needs to be replaced. This kind of key may also be a little cheaper.

Transponder Chips

More or less all new cars since 1995 have transponder chips inside the key head to disarm the immobiliser system. If you've got keys with a chip, the head is covered in a plastic cover that can be taken off to reveal an L-shaped metal key. Making a replacement key, or fob that is made using a transponder chip is a multi-stage process that involves precise cutting of replacement keys and programming of the transponder chip in order to synch up with the vehicle's immobiliser.

A transponder is an electronic chip with Non-Volatile Memory (NVM) that has a set of windings (very fine wire coiled around the tube) that look like the ones found in an electric motor. The windings generate a coded message that the car can read. If the code is correct, then the car will allow you to start it up.

There are two kinds of transponder chip, one known as the 80 bit, and the other is known as a circle + (General Motors). The first one can be reused, but has to be unlocked using a special machine in order to work on a different vehicle compatible with it. The latter one is more difficult because the previous ones are often broken and drilled or discarded after key cases are replaced. They are able to be salvaged however for use with an ad-hoc key that doesn't need a battery to operate.

Immobiliser Systems

Immobiliser systems are electronic security measures that deter thieves from starting your car. It works by sending an electronic signal from the car to the key whenever you attempt to start it. The electronic chip inside your key then responds with an unique code that must match that in the vehicle to start. If the codes do not match, the engine will shut down immediately to stop theft.

Modern smart keys and fobs feature an embedded transponder chip that stores security information in a format that cannot be duplicated. When the key or fob are placed in the ignition, they transmit this code to the ECU. The ECU is able to compare this code with the one in its memory and activates the fuel system and the ignition circuit if they are compatible. If the codes don't match, your engine will not start - even if an armed robber attempts to short-circuit the ignition circuit.

Replacing a fob or a key is a multi-stage process that involves precise cutting of the new blade of the key and programming it to synch with the immobiliser system of your vehicle. Every immobiliser system is unique and has its own unique programming procedure. We employ Ross-Tech to ensure that the replacement key is correctly programmed. This will ensure the best performance and security.
