Lexus Key Replacement - Replacing a Remote Or Fob If you have a traditional Lexus key that is used to turn on the ignition, or a smart key for your car that begins with the push of an arrow, eventually the battery in your fob will run out. Replacing lexus spare key is as simple as a paperclip: Take the existing battery out and then insert the new one (refer to the manual for your owner to determine the type of battery you need) and then clip it back into place. Keys Lexus keys aren't always easy to replace. A professional locksmith is required to design an appropriate replacement that functions. This is due to the fact that every Lexus key has an embedded microchip that must be programmed to sync with the immobiliser of your vehicle If it is not, the car will not be able to start. This process takes time and special equipment to do right, and each model has a distinct procedure for programming. Replacing keys or remotes is a cost-effective service that should be left to experts, unless equipped with the proper equipment and know-how. No matter if you're using a conventional key that rotates in the ignition barrel, or a smart key that will start the car with the click of the button they will both eventually need their batteries replaced. You can save money by doing it yourself, but you'll need the use of a small Phillips screwdriver and coins (a 20p piece works best) and a paperclip. On the back of the fob, you will find two or more screws loosen them and place them in a safe location (they're small and easily lost). Remove the fob and you will see an indentation that is circular for the key made of metal. Take the battery out (using the paperclip) and insert the new one ensuring that it's pointing the right way up. Clip the inside of the key to secure it. Remotes Lexus remotes and fobs aren't easy to replace and require locksmiths who are knowledgeable and have the right tools. Some models require that the transponder chip in the key be programmed in order to work with the car's immobiliser system. The Lexus models use different methods to program these chips. This is done using a specific device that sends a code chip to unlock the doors or start the engine. Certain Lexus models are built with a key head that is a combination of the key head and remote. They are much easier to replace since there is no separate chip required. This kind of key is also cheaper. All fobs eventually lose their battery power, regardless of the kind of key. This can be a very frustrating experience, but it is possible to get your Lexus back in operation with a bit of know-how. First, check the owner's manual to identify the type of battery you need and locate a replacement. Locate a small hole on the inside of your fob. Insert an amount of money (20p is a good choice) into the hole and then twist. There should be a flat surface that you can remove with an ordinary paperclip. Next, pop the old battery off and insert the new one. Make sure that the replacement battery is inserted with the correct the polarity. Clip the two sides of your fob to insert the key in the metal. Transponder Chips Nearly all new cars manufactured after 1995 have transponder chips in the key head to disable the immobiliser system. If you have a key with a chip inside, the head comes with a cover that can be taken off to reveal an L-shaped metal key. A transponder-chip replacement key or fob is a process that involves multiple stages. It involves cutting the keys accurately and programming the chip to sync up with the vehicle's immobiliser. A transponder is a type of chip with Non-Volatile Memory. It has a set windings that are fine wires wrapped around a tube. They resemble the ones in an electric motor. These windings transmit a message that the car is able to read. If the code is valid, then the car will allow you to start it up. There are two types of transponder chip, the first is called the 80-bit, while the second is called the circle + (General Motors). The former type is reusable but needs to be unlocked by a specific machine in order to be used in a compatible vehicle. The latter is a bit more difficult, as the older ones are often broken and then drilled through or thrown away when key cases are replaced. They are able to be salvaged however and then used to create the service key, which does not require a battery to function. Immobiliser Systems An immobiliser system is an electronic security measure that stops thieves from starting your car. It operates by sending a signal from the car to the key when you attempt to start it. The electronic chip in your key responds by sending a unique code that must match the one found in the vehicle to start. If the codes don't match, the engine will stop immediately, preventing theft of your car. Modern smart keys and fobs are equipped with an embedded transponder that can store electronic security information in a format which cannot be easily copied. When your key or fob is inserted into the ignition, it transmits this code to a receiver in the ECU. The ECU is then able to compare it with the code in its memory. It then activates the ignition and fuel system circuit if they match. If the codes do not match the engine won't start, even when the ignition circuit is short-circuited by a burglar. Replacing a lost or damaged key is a multi-stage process that involves accurate cutting of the new key blade, and programming it to connect with your car's immobiliser system. Every immobiliser system is unique and has its own programming procedure.
