Changing the battery

Separate remote fob

The remote is a small standalone unit. You will not need to touch the ignition key at all.
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.
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.

This key takes two CR2016 cells. Change both at the same time and stack them the way the old pair sat; mixing a fresh cell with a tired one shortens the life of the new one.

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.
Use the slot where the metal key sat. Twist, do not lever hard, and work along the seam until the halves separate.
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.
Reassemble, refit the emergency key, and check that the car sees the fob when you press 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.

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.

Keep spare coin cells away from small children. A swallowed coin cell can burn the throat within hours; if it happens, go to an emergency room at once.
