Changing the battery
Separate remote fob
- A separate fob has no key blade inside, so it opens with nothing but a coin or a small screwdriver.
- 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.
- Lift the old coin cell out and press the new one in with matching orientation.
- 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.
If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
