Where to Replace the Car Key Battery When It Runs Out?

[LucasDella]

When the car key runs out of battery, it is usually possible to purchase the battery and replace it yourself. Alternatively, you can go to a 4S shop and have the staff replace it for you. Most car keys use button batteries, and you only need to know the battery model to purchase and replace it yourself, which is very simple. As for the battery model, it will be indicated in the vehicle's user manual. The replacement method is also straightforward, with the general steps being: 1. Remove the mechanical key. 2. Open the key's outer shell. At this point, you can see the key's battery. 3. Remove the old battery and directly replace it with a new one. 4. Reassemble the key.
