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.
- 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 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.
Smart key (push-button start)
- Most push-button fobs hide a metal backup key. Press or slide its catch and draw the key out first.
- The gap left by the metal key usually has a pry point. A slow twist with a thin flat tool (tape on the tip saves the plastic) opens the two halves.
- Note which side of the old coin cell faces up (usually the side with the writing), lift it out with a plastic tool, and press the new one in the same way.
- Reassemble, refit the emergency key, and check that the car sees the fob when you press start.

Key with remote in the head
- This type has the buttons built into the key head. The cell is inside that head, between two clipped halves.
- Many key heads split along the side seam. Start at the small notch and pry a little at a time.
- The coin cell is usually under or on the back of a small board. Keep the rubber button pad in place while you swap the cell.
- Snap it closed and press each button. The car still starts with a dead remote battery on most of these keys, because the start chip needs no battery.
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.
Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
