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.
- 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.
- 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 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)
- Find the small release on the edge or back of the fob and hold it while you pull out the metal emergency key.
- Look inside the empty key slot for a notch. Put the tip of the metal key or a small flat screwdriver wrapped in tape there and twist gently until the shell splits.
- Pop the old battery out with a toothpick or plastic pick, not a metal blade, and seat the new one with the + side matching the old one.
- Close the case until it clicks all the way round, put the metal key back, then try the buttons and a push-button start.

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