I had one of those days yesterday.
1st job....open Kwikset deadbolt & leverset I rekeyed 1 month before.
Picked deadbolt easily but leverset wouldnt budge.
ended up guessing combination and finding a key in the truck to modify...as it wouldnt pick or bump.
2nd job....replace kwikset knobset...customer wouldnt spring for new one so had to use a second handy I had prepared for a demo on bumping (for an insurance company).
3rd job...install safe....simple but boring...
4th job....repair door that wouldnt close properly....some people are so lazy...and just cant think for some reason.
(enough venting)....roll on weekend.
