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.
- Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
- Reassemble and test from a short distance.
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.
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.
- Work a thin flat tool into the seam near the blade and twist; go round slowly if it does not open at once.
- 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.
- Close the head, check there is no gap, and try the buttons.
A CR1616 is 16 mm across and 1.6 mm thick. It is easy to confuse with the 20 mm CR20xx sizes, which will not fit.
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.
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.
- Use the slot where the metal key sat. Twist, do not lever hard, and work along the seam until the halves separate.
- Before you take the old cell out, look at its face. Put the new cell in with the same side showing, and avoid touching both faces at once.
- Reassemble, refit the emergency key, and check that the car sees the fob when you press start.
Honda smart keys typically have a release lever for the built-in key. Twist a coin or the key tip in the slot it exposes to split the case.
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.
