Yesterday on HackADay there was a post linking to lock bumping. A very interesting technique for opening most of the current door locks.
It is a security vulnerability that is so severe because it is so terribly simple that it looks nearly like magic. A guy inserts a self made key into a lock, hits it with the head of a screwdriver and the lock pops open. Having only 10 most common bump keys you can open about 90% of the current door locks.
You can see a full video about lock bumping on the Toool home page here recorded on WTH this year. There is also a list of locks that are not vulnerable to the bumping attack.
I really encourage you to check if your door lock is vulnerable and get a new one if you can. The only real problem is that there are not many good lock under 100Eur level. But everyone knows how much security is important for him.
