My Tips for Replacing the Battery
When I replace my key fob battery, I handle the fob carefully so I don’t damage the case or internal parts. I use a small flat tool or coin to open it gently, then I swap the battery with the correct side facing the right direction. After that, I test the fob right away to make sure it works.
