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. Swap the cell or cells, keeping the same side up as the old ones.
  4. Reassemble and test from a short distance.

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.

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)

  1. Most push-button fobs hide a metal backup key. Press or slide its catch and draw the key out first.
  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. Note which side of the old coin cell faces up (usually the side with the writing), lift it out with a plastic tool, and press the new one in the same way.
  4. 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.
