If your car key battery is dead, simply replace the battery. The method and precautions for battery replacement are as follows: Method to Replace the Key Battery: Gently press the small switch on the back of the key to remove the mechanical key. You can then use the mechanical key to open the key cover by inserting it into the slot next to the key and gently prying it open. Remove the key compartment cover, and you will see the position of the old battery. It is recommended to use a small flat-head screwdriver to more easily remove the old battery. Ensure the new battery is placed with the positive side facing up. Reinstall the key cover and mechanical key, and confirm that the key functions properly. Precautions for Battery Replacement: Do not use the wrong battery. The battery life of a smart car key is approximately one year.
