    How Can I Fix Stiff Door Locks?


    My front door’s lock has become very stiff recently when I try to turn the key in it to unlock it. However, it doesn’t seem to bad when locking the door. I’d like to solve this soon so I don't get locked out.
    It seems to have gone worse over time and is now consistently stiff, despite the door and lock only being a few years old.
    Is there anything I can do to make the lock a bit looser? Or is it more likely that I need to replace the door’s lock?
    If anyone has any ideas for what could have caused this, please let me know – as I don’t want any repeats of this in future.

    "It may need to be replaced or an adjustment to the fit. You could try a little spray oil but not too much, put some on tock lock bolt and lock and unlock it with the door open and just see if it works. If not, you will need to get a locksmith to have a look at it."

    "Squirt some WD40 in the lock. If it still persists then the lock needs changing."
