A couple personal experiences:
-- A friend who was handy with locks showed me how easy it was to "pick" locks - he had a dozen different ones open in less than 30 seconds each, including the front door & assorted locks at the wash. He showed me how to do it and I got a few basic locks open within a few minutes. Rather disconcerting. Home Depot locks, never again for me.
-- When someone literally kicked the ER door in at my wash 20+ years ago, I replaced the door and put in ASSA deadbolts - supposedly among the best out there. A couple years ago when I got robbed, they spent 1/2 hour on the assa deadbolts and couldnt get in. So they eventually had to literally cut the door (power tools) around the deadbolts to get in.
Very expensive, but worth it IMO, so thats what I have.
I have a "push bar" on the inside of the door so I can easily open from the inside when my hands are full of
vending supplies. The outer door knob is the handle type that I can push down with my monkey dexterous foot when my hands are full. As opposed to a round knob. It does have an assa cylinder in it (key matched to the deadbolts) that I could
lock from the inside so it would automatically
lock the door when the door closes, but I generally dont use that. Yes I also put in an auto-door-closer which is quite handy.
