Ordinary pin-tumbler locks with some wear on them are embarrassingly easy to pick. Raking or bumping usually works. Just apply some tension and stick in something that lets you move the pins.
There's a marketing reason for this. If you design a lock that wears out into a locked condition, customers eventually get locked out and are angry. If you design a lock that wears into an easier to unlock condition, customers don't notice.
So I just treat it as a useful skill to have in emergencies. I leave a set of picks in my cars' glove compartments and a very crude set (a very basic tensioner and a bunch of hairpins) in my yard. Has come in handy a couple of times when I've locked myself out.
I was able to open padlocks effortlessly, but my front door deadbolt kicked my butt.
