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. Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
  3. Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
  4. Reassemble and test from a short distance.

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.

Key with remote in the head

  1. Here the key blade and remote are one piece. You open the plastic head, not the blade.
  2. Work a thin flat tool into the seam near the blade and twist; go round slowly if it does not open at once.
  3. Inside you may find a small circuit board in a tray. Lift the board out if the cell is underneath, swap the cell with the same side up, and refit the board.
  4. Close the head, check there is no gap, and try the buttons.

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.

Keep spare coin cells away from small children. A swallowed coin cell can burn the throat within hours; if it happens, go to an emergency room at once.
