Changing the battery
Separate remote fob
- The remote is a small standalone unit. You will not need to touch the ignition key at all.
- Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
- Replace the cell, keeping the + side where it was, and check the small metal tab still touches it.
- 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.
