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.
- Turn it over: some older fobs use one small screw, newer ones just clip. Pry at the seam once any screw is out.
- Lift the old coin cell out and press the new one in with matching orientation.
- 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.
A CR2450 is 24.5 mm across and 5.0 mm thick, much fatter than a CR2032. A thinner cell will rattle and lose contact, so buy the exact size.
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.
- 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.
- 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.
- Close the case until it clicks all the way round, put the metal key back, then try the buttons and a push-button start.
On many recent GM smart remotes a button on the side releases the key; the slot at the bottom is where the case opens.
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.
