I’ve installed lots of new doorknobs and deadbolts and have never had this problem. Everything seems to work properly until it’s installed in the door. I’ve replaced the knob and deadbolt on this particular door several times, too. (It’s a rental unit). The old knob works fine but the tenant did not return the keys so I’m replacing it.
When I turn the knob the latch retracts fine, but gets stuck there. It won’t release when you let go of the knob. I’ve tried loosening the bolts a tiny bit, but not so much that the knob jiggles, thinking maybe it was all too tight, but that doesn’t help. It’s brand new so there’s plenty of lubricant. Is it just faulty and I should return it?
