Changing the battery

Separate remote fob

  1. The remote is a small standalone unit. You will not need to touch the ignition key at all.
  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. 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.

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