In college, my friend (who was by no means an expert) picked the lock on the elevator with a paperclip and a shim. These "locks" are only designed to keep out the honest people.
I remember in my teens picking old locks simply with two paperclips. All locks sold in normal stores can be picked with very basic tools. Any house lock can be very quickly unlocked by a professional. There are plenty of videos on YouTube showing just how much of a joke most all locks are. Deadbolts can be picked with household items. Those sliding locks with chains can be defeated with just a rubber band.
That's funny. My workplace has a lot of very very expensive gear, and I never got a key. The roller grill is the type you see in malls and arcades. Any small key will get me in, and once a small spoon did too.
