While locking up our trailer I had one of those "something's not right" moments and sure 'nuf, found that the strike plate was mounted too high in the door jamb.
is a pretty good re-enactment of my deadbolt on repeated attempts!
After removing the strike plate, removing 3/8" of the door jamb with a Dremel cutting disc and re-mounting the plate we now have a functional deadbolt. A QC fail at the factory, but thankfully corrected at no cost.
