Why Lexus Car Key Is Right For You?
Lexus Key Replacement - Replacing a Remote Or Fob
The battery inside the key fob will eventually run out, whether you own an ordinary Lexus Key that turns the ignition or an intelligent key for your vehicle that can start by pressing a button. Replacing it is as simple as using a paperclip. Pop the existing battery out, insert the new one (refer to the owner's manual to determine which kind of battery you require) and then secure it back into place.
Keys
Lexus keys aren't always easy to replace. A specialist locksmith is required to create an original replacement that works. This is because each Lexus key contains a microchip that needs to be programmed to sync with your vehicle's immobiliser system - if not it will not be able to start.
It requires a lot of time and equipment that is specially designed for this procedure to be completed correctly. Each model has its own programming procedure. Replacing keys or remotes is a costly task that should be left to professionals, unless you are equipped with the right equipment and know-how.
If you have a traditional key that is turned on in the ignition barrel, or an electronic key that starts the car at the push of an arrow Both will eventually require their batteries replaced. You can save money by doing it yourself, but it requires a small Phillips screwdriver and an old coin (a 20p piece is a good choice) and a paperclip. There are two or three screws on the back of the fob of the key. Unscrew them and store them securely (they are small and easy to lose). Remove the fob to reveal a circular indentation for the key made of metal. Pop the battery out (using the paperclip) and insert the new one ensuring it's the correct way up. Then clip the inside of the key back together.

Some models require that the chip inside the key be programmed to function with the vehicle's immobiliser system. The chips are programmed using different methods based on the model of Lexus. This is done using a specific device that sends a code chip to unlock the doors or to start the engine.
Some Lexus cars are equipped with a single piece of hardware that incorporates the key head and remote. These are easier to replace since no separate chip is required. This type of key is also a bit cheaper.
All fobs eventually lose their battery power, regardless of the kind of key. It can be very frustrating however, with a little know-how you can get your Lexus back to normal. The first step is to consult the owner's manual for the type of battery you need and locate a replacement. Find a small opening on the inside of the fob. Insert an amount of money (20p works well) into the hole and then twist. You should see a flat surface that you can get rid of using a paperclip.
Then, take out the battery that was used and replace it with the new one. Make sure that you insert the battery in the proper direction of operation. Clip the inside of your fob together and insert the key made of metal.
Transponder Chips
More or less all new cars built since 1995 have transponder chips in the head of the key to disable the immobiliser system. If you've got a car key with a chip inside, the head comes with a cover that can be pulled off to reveal an L-shaped key. Making a replacement key, or fob made with a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys as well as programming the transponder chip to synch up with the vehicle's immobiliser system.
A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire twisted around a tube) which look similar to ones in an electric motor. These windings form a coded signal that the car can read. If the code is correct the car will begin to move.
There are two types of transponder chip, the one is known as the 80-bit and the second is known as the circle + (General Motors). The former is reusable but needs to be unlocked by a special machine to function in a compatible vehicle. The latter one is more difficult since the earlier keys are usually broken and then drilled through or discarded when key cases are replaced. They can be salvaged, however and used with a service key that does not require a battery to function.
Immobiliser Systems
Immobiliser systems are electronic security measures that deter thieves from starting your vehicle. It works by sending an electronic signal from the car to the key every time you attempt to start it. The electronic chip inside the key responds by sending a unique number of codes that must match the one of the vehicle to allow it to start. If the codes don't match, your engine will stop immediately to prevent theft.
Modern smart keys and fobs have embedded transponder chips that stores electronic security in a format that can't be duplicated. When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU is able to compare this code with the one that is stored in its memory, and activates both the fuel system and the ignition circuit if they are compatible. If the codes don't match, your engine will not start, even if a burglar tries to short-circuit the ignition circuit.
Replacing a key or fob is a multi-stage process that involves precise cutting of the new key blade, and programming it to synch with your car's immobiliser system. Every immobiliser system is unique and has its own programming procedure. We employ Ross-Tech to ensure that the replacement key is programmed correctly. This will ensure the highest performance and security.
