How to Replace a Dead Car Key Battery?
1 Answers
Here are the steps to replace the battery: 1. If the key is foldable, after flipping out the mechanical key, you can see the clasp at the folding position. Use a tool to press the clasp, and you can remove the outer shell. 2. If it's a hidden mechanical key, after opening the key shell, remove the old button battery. Check if the model of the new battery matches the old one, then replace it with a new button battery of the correct specification. Pay attention to the installation position and make sure not to install it backwards. Below is related information about the functions of car keys: 1. Automatic unlocking: The chip in the smart card carried by the owner automatically senses and unlocks the door. When the owner approaches the car, the key and the car begin to exchange preset command information via radio waves. Subsequently, the car's locking system, security system, and engine control system are all activated. 2. Smart ignition: The driver needs to insert the key into the ignition keyhole to start the engine. The keyless start feature of smart keys makes this process more convenient. 3. Owner identification: Each smart key has a unique ID code corresponding to the vehicle's ID code. Even if the key is duplicated, the vehicle cannot be started without the ID code.
