Fixing Door Locks and Door Knobs

What to do when your door locks are stuck or keys don’t work, and latches that don’t latch

Most door lock and knob problems can still be amended before your lockset gives up. The usual root of the trouble is a faulty latch assembly or lock system. Sometimes, a malfunctioning latch is due to an ill-fitting door. But there are times that locks fail to work usually because of dirt. It simply needs a clean or graphite lubricant. But for complex lock problems, it is best to call a locksmith to resolve the mechanical issue or to change the lock completely.

If is normal for doorknobs to become loose over time. There are ways to tighten door knobs depending on what type of lockset they are. An ordinary interior mortise lockset can be tightened by:

1) Easing the set screw on the knob’s shank;

2) Keep the knob on the other side of the door steady, and try to wind the slacking knob clockwise until it fits well. Fasten the screw till it sits against the flat side of the spindle. The knob should round smoothly;

3) If number 2 doesn’t work, pull out the knob and do a spindle check; if the spindle is worn-down, it is time to replace. But if the entire lockset is timeworn, it is best to get a new lockset.

You can try cutting some blade from a coping saw to hook and drag the key out. If this still doesn’t work, you can remove the cylinder. Stick a stiff wire into the cam slot at the back of the cylinder and push the key out. Or get the cylinder to a locksmith.
