One common problem is the screws in the top hinge of the door have become loose. This allows the door to hang crooked in the frame affecting where the deadbolt extends. Try tightening the screws in the hinges and give the deadbolt a try again.
Also asked, why is my door lock loose?
Lining up the Doorknobs In most cases, a door lock becomes loose simply due to the over-and-over torquing of turning the knobs. Over time, the screws work loose. You will need to line up the two halves of the doorknob assembly to make it easier to tighten the screws.
In this regard, can you use wd40 on a deadbolt?
It is not recommended to use WD-40 in or on any type of door locks or deadbolts. The WD-40 lubricant will work for a short time to lubricate but will eventually gum up the pin tumblers and cause them to stick in the chamber therefore making it difficult to unlock the door.
How to Fix a Misaligned Door
- Open and close the misaligned door to look for areas where it sticks or doesn't line up correctly.
- Check where the latch on the door hits the strike plate on the frame.
- Tighten the screws on the hinge plate that holds the door onto the frame.
