You can also use the piece of awing to slip in between the doorframe and door latches (not the bolt type) to unlock house doors. Back in the day, I didn’t have a house key so used various items like that to get into my house after school. Just as quick as a key and didn’t have to worry about losing a key. My parents never understood just how unsecured the house really was.

I've done the same with a pocket knife. Never tried anything else, because I always have a pocket knife.
