Using a phillips head screwdriver tighten all door hinges so that none is loose.
They dont make my door handle anymore.
A very common problem that is associated with door knobs is that they do not latch properly.
Tap the end of a chisel under the door stop on the striker side of the jamb.
Shut the door and try to lock it.
Door lock doesn t latch properly when a door latch doesn t click into position it usually means the latch and the strike plate are out of alignment.
Sure you could do this yourself each time you close the door e g lift up on the door as you close it to force the latch bolt up into the latch bolt hole but let s do the right fix and do it one time.
Key will not work if you ve had a new spare key cut recently it could be a poorly cut key causing the problem.
Tighten the hinge screws and then try adjusting the strike plate by loosening its screws and shifting it slightly.
Pry up on it until it comes loose and remove it.
If it won t lock open the door.
Now try closing the door and give it a push.
When this happens the door does not shut and opens up at any time.
