Lexus Key Replacement - Replacing a Remote Or Fob
No matter if you have a standard Lexus key that switches on the ignition or a smart key for your car that activates with the push of a button, in time the battery inside your key will go out. It's easy to replace it with using a paperclip. Pop the existing battery out and then insert the new one (refer to the owner's guide to see which type of battery you require) and then clip it back in place.
Keys
Lexus keys are not easy to replace and require a professional locksmith for car keys to create a spare working. Each Lexus key is equipped with an embedded microchip that must be programmed to work with the immobiliser system of your vehicle.
The process takes time and special equipment to execute properly, and each model has its own unique procedure for programming. Replacing remotes or keys is a cost-effective service that should be left to professionals unless you are equipped with the proper tools and knowledge.
You'll need to replace the batteries in your smart key or conventional key. Both keys operate by turning the barrel of the ignition. This can be done yourself, but you will need the smallest Phillips Screwdriver, a 20p coin and a paperclip. You will find two or three screws on the back of the fob of the key. Unscrew them, and store them safely (they are small and easy to lose). Remove the fob, revealing an indentation that is circular where the metal key will be. Take the battery out with the help of a paperclip. Insert the new battery, ensuring that it is inserted correctly. Then, clip the outside of the key back to the fob.
Remotes
Lexus remotes and fobs aren't easy to replace and require locksmiths who are skilled and possess the appropriate tools. Certain models require that the transponder chip within the key be reprogrammed to function with the immobiliser system of the car. These chips are programmed by different methods based on the model of Lexus. This is done with a special device that sends a signal to the chip that matches the code used to open the doors and start the engine.
Certain Lexus cars are constructed with a single piece of hardware that includes the key head as well as the remote. These are simpler to replace as there is no separate chip. This kind of key is also a bit less expensive.
Regardless of the key type no matter what type of key it is, all fobs eventually run out of battery power. It can be frustrating, but with a bit of knowledge you can get your Lexus back in operation. First, consult the owner's manual to identify the kind of battery you need and find the replacement. Find tiny holes on the inside of the fob. insert the coin (a 20p piece is ideal) and twist. There should be an area flat which you can easily remove using an ordinary paperclip.
Next, pop the old battery out and insert the new one. Be sure to insert the battery in the correct polarity. Clip the inside of the fob together, then insert the metal key.
Transponder Chips
Transponder chips are found in the keys of nearly all new cars built since 1995. They are used to disable immobiliser systems. If you've got a car key that has a chip inside it, the head comes with a cover that is able to be pulled off to reveal an L-shaped key. A replacement key or fob made with transponder chips is a multi-stage process that includes precise cutting of replacement keys as well as programming the transponder chip to link up with the vehicle's immobiliser.
Transponders are electronic chip that has Non-Volatile Memory (NVM) that has a set of windings (very fine wire that is wrapped around a tube) that resemble 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, the one is known as the 80-bit while the other is known as the circle + (General Motors). The former is reusable but must be delocked by a specific machine in order to function in a different compatible vehicle. The latter one is more difficult since the earlier keys are usually damaged and drilled or discarded when key cases are replaced. However they can be utilized with a service key that doesn't require a battery.
TheKeyLab is a security measure that uses electronic technology which prevents thieves from opening your vehicle. It works by sending a signal from your car to the key when you attempt to start it. The chip inside the key responds by transmitting a unique code that must match the one of the vehicle in order for it to start. If the codes do not match, the engine will stop immediately, preventing theft of your vehicle.
Modern smart keys and fobs come with an embedded transponder that can store electronic security information in a format that can't be copied easily. When your key or fob is placed in the ignition, it transmits the code to a receiver in the ECU. The ECU examines the code against the one stored in its memory, and then activates the fuel system and the ignition circuit if they match. If the codes do not match then the engine will not start, even when the ignition circuit is short-circuited by a burglar.
Replacing a lost or damaged key is a multi-stage process which involves precise cutting the new key blade and programming it to synch with your car's immobiliser system. There are many different immobiliser systems used in different years and models and each one requires an individual programming procedure. We use Ross-Tech software to ensure that your replacement key is programmed correctly to ensure optimal performance and security.
