I need to replace door lock upvc what has no keys Ive tried unscrewing retaining screw on side of door, screw head sheared off so used a screw extractor to no avail, its to go on my shed in garden, so no threat to home, anyone help, cheers.
If the lock sticks out 5mm on either side of the door get a pair of pliers and grap the lock and waggle side to side so the lock will snap in the middle.
