Changing the battery

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. 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.
  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. Snap the halves back together, slide the metal key home, and press each button, then try the start button from the driver's seat.

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

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.
