Door to the garage suddenly stopped closing with just a push. The bolt is sticking against the strike and the knob has to be turned to retract the bolt before the door can be closed. (Schlage F lockset.) Does something need lubrication, or is it time for a new lockset? A little grease on the beveled edge of the bolt didn't help.
I've been meaning to change all the F locksets in the house when my pin money comes back up to snuff, but a few unexpected expenses have tightened the budget (and my own limited knowledge doesn't suggest replacement will fix it anyway).
