deadbolt that sometimes jams, what is problem?
I have a Schlage deadbolt installed in an exterior door, 5 yr old, that occasionally will only partially open. At these times, I can't turn the key further - it seems to be stopping on something. If I continue to turn it out and in, I have eventually been able to get it to withdraw totally, at which point it functions normally for another day or couple of weeks. I fear at some point it will remain in the locked position, effectively isolating me from my garage.
Anyone know what might be causing this and how to fix? Should I disassemble the lock and look for something that is being caught?
