Changing the battery
Separate remote fob
- The remote is a small standalone unit. You will not need to touch the ignition key at all.
- Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
- Swap the cell or cells, keeping the same side up as the old ones.
- Close the fob and test it. If it does not work, open it again and check the cell is seated flat.
A CR1616 is 16 mm across and 1.6 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.
