Changing the battery

Separate remote fob

  1. This remote is its own fob, separate from the metal key, which makes it one of the easier ones to open.
  2. Turn it over: some older fobs use one small screw, newer ones just clip. Pry at the seam once any screw is out.
  3. Swap the cell or cells, keeping the same side up as the old ones.
  4. Reassemble and test from a short distance.

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.

A CR2025 is 20 mm across and 2.5 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.

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