Changing the battery
Separate remote fob
- This remote is its own fob, separate from the metal key, which makes it one of the easier ones to open.
- 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.
- Swap the cell or cells, keeping the same side up as the old ones.
- 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.
Key with remote in the head
- Here the key blade and remote are one piece. You open the plastic head, not the blade.
- Many key heads split along the side seam. Start at the small notch and pry a little at a time.
- Replace the cell with the same face showing, and make sure the rubber keypad sits flat before closing.
- Press the head together until it clicks and test the buttons. The transponder chip that lets the car start is separate from the battery, so starting should not change.
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.
If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
