Changing the battery
Separate remote fob
- A separate fob has no key blade inside, so it opens with nothing but a coin or a small screwdriver.
- Turn it over: some older fobs use one small screw, newer ones just clip. Pry at the seam once any screw is out.
- Lift the old coin cell out and press the new one in with matching orientation.
- Close the fob and test it. If it does not work, open it again and check the cell is seated flat.
A CR2032 is 20 mm across and 3.2 mm thick. CR2032, CR2025 and CR2016 share the same width but not the same thickness, so a swap between them can leave a loose contact or a case that will not close.
Remote key (form not stated in the source)
- The source for this row does not say which shape of key it is, so check your fob before you start.
- Look for a notch, slide or screw on the case. A coin or small flat screwdriver, twisted gently, opens most fobs.
- Replace the cell with the same side up, close the case, and test.

If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
