Changing the battery
Key with remote in the head
- Here the key blade and remote are one piece. You open the plastic head, not the blade.
- Find the seam around the head. Twist a coin or small flat screwdriver in the notch at the blade end or side until the halves part.
- 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 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.
If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
