Separate remote fob
- This remote is its own fob, separate from the metal key, which makes it one of the easier ones to open.
- Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
- 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.
A CR1620 is 16 mm across and 2.0 mm thick. It is easy to confuse with the 20 mm CR20xx sizes, which will not fit.
If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
