The first step in fixing a door lock is that you should know where the problem exists. When you find the exact issue, it will be easy for you to sort it out. For this task, you should have sufficient time and patience too.

Tight the set of screws

If your knob of the door moves but the door does not open, this means that problem is with the loose set screw. This is the screw that supports the knob to the spindle and connects the interior and exterior knobs. Research shows that 58.3 of home break-ins occur when your door locks are loose, and this problem makes the task easy for burglars to play with the door lock issues. 

Follow the steps to fix a knob that twists but won’t open.

  • Some types of locks have apparent set screws located under the knob or on the neck of knobs. If you can’t see any screws, you should take the faceplate to reach the screws. 
  • With the screwdriver, tighten the loose screws, and spray the dry lubricant on them to make them run evenly.

Lubricate the lock mechanism

When you twist the knob and the deadbolt does not withdraw completely, it means there is a fault in the lock mechanism in the jammed locks. The spring mechanism makes the twisting of the knob easy for opening and closing the door.

  • Expose the spindle, and disassemble the knob because it is the central part of the locking mechanism.
  • Now spray the lubricant on the spring and spindle when you turn the knob. This will help in unbinding the spring locking mechanism, and the deadbolt will run smoothly. 
  • Remove the knob, and tight the screws well.

Fix the problem with jammed lock key won’t turn

The main reasons the jammed lock key won’t turn are insufficient lubrication, elevations on the key, and the cold weather. 

  • There may be elevations on the key that stops the key from turning. To make it smooth, apply a tiny amount of granite powder on the ticket, place it in the keyhole, hang it, and take it out. It would help if you filled the parts of the lock without granite on them to make it easy to rub against the locking mechanism. The key should go into the vital hole evenly, and it will unjam the lock.
  • If the deadlock does not twist in the open position, try to lubricate the key and keyhole to remove the rust that may be the cause of binding the lock.

Repair a broken door lock mechanism

To repair a broken door lock mechanism, you will need a unique tool known as a key extractor.

  • Pour the lubricant into the keyhole, then place the sharp end of the extractor into the keyhole. The elevations on the extractor should be in the direction of the peaks on the key. 
  • Now slip the extractor in and out direction until it interlocks in the keyhole grooves. After this, take out the extractor from the keyhole to remove the key. 

Bring into line the strike plate with the deadbolt

Due to some reason, the striker plate might slip, thus stopping the deadbolt from falling into the hole and locking the door. If the case is so, you should see the striker plate into the correct position and bring it to the level of the deadbolt.

  • To make it in a moving position, at the lower tip of the strike plate, place a chisel, and tap it with the hammer. The strike plate should move up to 1/8 inch in the downward direction so that the handle can slide easily.
  • You should try enlarging the strike plate hole if the door is still jammed. With the screwdriver from the jamb, remove the strike plate, and file down the lower tip of the strike plate with the metal file. Remove the most significant amount of metal for the deadbolt latch to slide easily into the hole. Now remove the strike plate. 
  • If enlarging or removing the strike plate does not give the right solution, and try to change its position. Now remove the plate from the lock, and replace it about 1/8 inch downs the old screw hole. The plate should now hold the latch and unlock the lock.
