It's scary fast even for me and I'm really just a dabbler. I came home one day and my wife had gone out unexpectedly. I hadn't brought my house keys because I didn't think I'd need them. I happened to have a small screwdriver and paperclip in the car. I bent up the paperclip a bit and used the screw driver as a tension bar. I literally took 2-3 SECONDS to open my locked house door.
Needless to say, I replaced the lock but even so, locks really just keep the polite people out.
