I think there is something to this. I used to lock myself out of the house all the time and end up calling a locksmith. A lot of the locksmiths didn't even bother with your typical rake/pry, they just jammed a gun like mechanism, hit a button, and about 1/10th of a second later the door opened. Others, though, dragged it out into a 2-3 minute exercise - and I was always wondering whether they were trying to justify their $150 3:00 AM surcharge.
