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. Turn it over: some older fobs use one small screw, newer ones just clip. Pry at the seam once any screw is out.
  3. Lift the old coin cell out and press the new one in with matching orientation.
  4. Snap the case shut and watch for the lights to flash when you press lock at the car.

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.

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.
