Lexus Key Replacement – Replacing a Remote Or Fob No matter if you have a standard Lexus key that turns in the ignition, or a smart key for your car that starts with the push of a button, eventually the battery inside your fob will die. It's easy to replace it with an ordinary paperclip. Simply remove the old battery, replace it with the new one (refer to the owner's manual to determine the type of battery that you require) and then clip it back into place. Keys Lexus keys aren't always easy to replace. A professional locksmith is required to create an original replacement that works. This is because each Lexus key is equipped with a microchip that needs to be programmed to sync with your vehicle's immobiliser system and if it's not, it'll not start. It requires a lot of time and specialized equipment to allow this procedure to be executed correctly. Each model has its own procedure for programming. Replacing a key or a remote fob can be a costly task and one you should leave to professionals unless you have the proper tools and knowledge. You will have to replace the batteries in your smart key or traditional key. Both keys work by turning the barrel of the ignition. You can save money by doing this yourself but it will require only a small Phillips screwdriver as well as an old coin (a 20p piece works best) and a paperclip. There are one or two screws on the back of the key fob. Unscrew them, and then store them in a safe place (they are small and easy to lose). The fob can be removed to reveal an indentation with a circular shape that houses the metal key, pop the battery out (using the paperclip) and insert the new one making sure it's facing the right way up. Then clip the inside of the key back to the fob. Remotes Lexus remotes and fobs can be difficult to replace and require locksmiths who are both well-versed and have the proper tools. Certain models require that the chip inside the key be programmed in order to work with the immobiliser system of the car. These chips are programmed using different methods based on the model of Lexus. This is done using a special device which sends a code chip to unlock the doors or start the engine. Some Lexus cars are designed with a device that combines the key head and the remote. These are easier to replace, since there is no separate chip to replace. This kind of key is also a bit less expensive. No matter what type of key no matter what type of key it is, all fobs eventually run out of battery power. This is a stressful experience, but it is possible to get your Lexus back up and running with a little knowledge. First, consult the owner's manual to identify the type of battery you need and find the replacement. Find a small hole on the inside of your fob. Insert a coin (20p works well) into the hole and then twist. This should reveal an unflattened area that you can make use of a paper clip to take away. Then, take out the battery that was used and replace it with the new one. Make sure that the new battery is inserted with the proper polarity. Then, clip the outside of the fob back together and reconnect the key to the metal. Transponder Chips Transponder chips are in the key heads of a majority of new cars manufactured since 1995. They are used to disable immobiliser systems. If you've got keys with a chip inside, the head is covered in a plastic cover that can be pulled off to reveal an L-shaped key. Making a replacement key, or fob with a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys and programming the transponder chip in order to synch up with the vehicle's immobiliser system. Transponders are electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire that is wrapped around tubes) that look like the ones found in an electric motor. The windings generate a coded message that the car read. If the code is correct then the car will allow you to start it. There are lexus car key of transponder chips. One is known as the 80 bit and the other one is called a circle + (General Motors). The first kind is reusable, but must be delocked using a specific machine in order to work on another compatible vehicle. The second kind is more difficult to use as the older keys could be damaged, broken or thrown out when key cases are changed. They can be salvaged, however and used with an ad-hoc key that doesn't require batteries to operate. Immobiliser Systems Immobiliser systems are electronic security devices which prevent thieves from starting your car. It works by sending a signal from your vehicle to the key whenever you attempt to start it. The electronic chip in the key responds by sending a unique code which must match that of the vehicle in order for it to start. If the codes don't match, the engine will shut down immediately and stop the theft of your vehicle. Modern smart keys and fobs are equipped with embedded transponder chips that stores security information in a format that cannot be duplicated. When the fob or key are inserted into the ignition, they transmit this code to the ECU. The ECU compares this code with the one stored in its memory, and activates both the fuel system as well as the ignition circuit if they match. If the codes do not match and the engine does not start even if the ignition circuit is damaged by a thief. The process of replacing a key or fob involves a multi-stage procedure that includes cutting the new blade with precision and programming it to ensure that it is compatible with your car's security system. There are a variety of immobilisers that are available in various models and years, and each requires the use of a unique programming method. We utilize Ross-Tech to ensure that the replacement key is correctly programmed. This will give you the highest level of performance and security.
