Car key batteries are available in supermarkets. Car keys typically use button batteries, which are generally sold in most large and medium-sized supermarkets. The method and precautions for battery replacement are as follows: Method for replacing the key battery: Gently press the small switch on the back of the key to remove the mechanical key. Then, use the mechanical key to open the key cover by inserting it into the notch beside the key and gently prying it open. Remove the key compartment cover to reveal the position of the old battery. It is recommended to use a small flat-head screwdriver for easier removal of the old battery. Ensure the new battery is installed with the positive side facing up. Reattach the key cover and mechanical key, and confirm 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. Battery consumption varies depending on the frequency of key usage. Different distances when using the car key will also affect power consumption. Be very cautious when replacing the battery of a smart car key, as any mistake can damage the circuit board inside the key.
