To determine if the issue is with your car battery or your key fob, try these steps: First, if your car has a push start button, put the key fob close to it and try to start the car. If the car starts, the battery might be fine, and your key fob could be the issue. Second, try unlocking the doors with the key fob. If it doesn’t work, the key fob battery likely needs replacement. If neither works, it’s more likely that the car battery is dead.
