Changing the battery
Separate remote fob
- A separate fob has no key blade inside, so it opens with nothing but a coin or a small screwdriver.
- Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
- Lift the old coin cell out and press the new one in with matching orientation.
- 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
- Open the flip blade. Never force the hinge sideways, since the spring and pin are the weak part of a flip key.
- 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.
- Take out the old cell, noting which side faced you, and fit the new one the same way.
- Press the halves together until no gap shows, then try every button.

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