To replace the housing of your keyfob:
- Stick a very small flat-head screwdriver into the small opening as shown in the video. Pry apart until it snaps open. Then use fingers to open it completely.
- Take the circuit board out of your old remote. Since you are doing this, you might as well replace the battery with a new one.
- Put it in the new case making sure the battery is facing the correct direction.
- Close the top and bottom shells.
