The front door has quit locking. For a few days, when you tried to lock the door, twisting the lock would catch half way. You could steady the door knob and it would lock. Well now it doesn't do anything. It will turn but the door never locks.
I went to Home depot to get a replacement knob and all of the knobs had life time warranties. It then occurred to me that maybe the current knob was also a life time warranty.
I came home to discover the knob may be made by Harloc. Googling it doesn't really come up with any warranty info or any way to contact Harloc. The guy at Home Depot said the company may no longer be in business.
I assumed since most of the building materials were high quality that the door knob was too. I took pictures of the knob. It doesn't really look like high quality at all.
I also googled how to repair a door lock, but didn't find any showing how to get to the lock itself.
