- 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.
- 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.
