Changing the battery

Key with remote in the head

  1. This type has the buttons built into the key head. The cell is inside that head, between two clipped halves.
  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.

Separate remote fob

  1. A separate fob has no key blade inside, so it opens with nothing but a coin or a small screwdriver.
  2. Look for a screw on the back or a notch on the edge. Remove the screw if present, then twist a coin in the notch to split the case.
  3. Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
  4. Snap the case shut and watch for the lights to flash when you press lock at the car.

A CR2025 is 20 mm across and 2.5 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.

If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
