Changing the battery

Separate remote fob

  1. A separate fob has no key blade inside, so it opens with nothing but a coin or a small screwdriver.
  2. Find the slot along the edge and turn a coin in it. Go slowly so the clips do not snap.
  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.

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