Changing the battery
Separate remote fob
- The remote is a small standalone unit. You will not need to touch the ignition key at all.
- Turn it over: some older fobs use one small screw, newer ones just clip. Pry at the seam once any screw is out.
- Lift the old coin cell out and press the new one in with matching orientation.
- Close the fob and test it. If it does not work, open it again and check the cell is seated flat.
A CR1620 is 16 mm across and 2.0 mm thick. It is easy to confuse with the 20 mm CR20xx sizes, which will not fit.
If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
