Changing the battery

Flip key

  1. Open the flip blade. Never force the hinge sideways, since the spring and pin are the weak part of a flip key.
  2. Some flip keys have a screw on the back; others just clip. Remove the screw if there is one, then pry gently at the seam.
  3. Take out the old cell, noting which side faced you, and fit the new one the same way.
  4. Clip the body closed, fold the blade, and test the buttons from a few steps away.

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. The remote electronics sit in the plastic head of the key itself, so there is no separate fob to open.
  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 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.

Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
