Changing the battery
Separate remote fob
- This remote is its own fob, separate from the metal key, which makes it one of the easier ones to open.
- Turn it over: some older fobs use one small screw, newer ones just clip. Pry at the seam once any screw is out.
- Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
- Close the fob and test it. If it does not work, open it again and check the cell is seated flat.
No battery to replace for these years, per the source shown.
If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
