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. Lift the old coin cell out and press the new one in with matching orientation.
  4. Snap the case shut and watch for the lights to flash when you press lock at the car.

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.

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. Find the seam or small slot on the body (often at the end away from the blade) and twist a coin or small flat screwdriver in it until the cover lifts.
  3. Swap the coin cell, keeping the same face up as the one you removed, and do not bend the metal contact tab.
  4. Press the halves together until no gap shows, then try every button.

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.
