Changing the battery

Separate remote fob

  1. The remote is a small standalone unit. You will not need to touch the ignition key at all.
  2. 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.
  3. Lift the old coin cell out and press the new one in with matching orientation.
  4. Close the fob and test it. If it does not work, open it again and check the cell is seated flat.

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)

  1. Find the small release on the edge or back of the fob and hold it while you pull out the metal emergency key.
  2. 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.
  3. 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.
  4. Reassemble, refit the emergency key, and check that the car sees the fob when you press start.

Cadillac smart remotes commonly hide a key behind a side button. With it out, the case opens at the bottom slot.

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.

Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
