Top 9 Links and Videos On Lock Bumping and Bump Keys via

Oh BuzzFeed you read my mind. I was just thinking about lock picking and or bumping.  I’ve practiced on my own door locks but I can’t get it to work as well as the guys in these links.

Wow, those really are the best 9 links I’ve seen on “Lock Bumping” or “Bump Keys”.  The really hard part is grinding down the tip and the shoulders of the key you are going to use as your bump key.  The easy part is getting the basic key cut with all settings on max or 9, depends on the key/lock that you want to bump.  Just go to whatever locksmith/keycutter nearest to you that won’t ask any questions.  Most won’t, some will laugh because they know what you are trying to do, but there is the occaisional asshole who thinks he’s friggin Judge Dread and won’t do it.  Its not illegal to posses or have bump keys cut, but it is illegal to use them on anything but your own property so stick to your own front door.  As for grinding down the shoulders and the tip of your key, a dremmel tool will do, but if you have access to something more accurate then use that instead.  Lastly you’ll need the “tomohawk” or basically a flexible plastic ruler with an eraser on the end.  That’s the part that you use to actually “bump” or hit the key while its in the lock.  My advice is to watch all the videos and read up, its not as easy as some make it out to be.

Happy Bumping!!

What makes lock bumping so problematic is that the insurance companies usually won’t pay because there is no sign of forced entry. Lock Jaw requires that you are in the house because you have to clip it to the deadbolt latch inside. I ordered some locks that guard against lock bumping from Antibump Locks.

Lock Jaw Security ( does require engaging from inside. The reason is because it is also portable…can even be installed with double-stick tape. Try that with door chains and door guards that also engaged once you’re inside. It doesn’t clip though, or at least that’s not how the ones we bought work. It’s a simple design that prevents the throw bolts from retracting through the strike plate on the door jam / frame. It basically has three mechanisms that work together. The door chains and door guards also engaged once you’re inside. With all the home invasions that’s what we were most concerned about. Regardless, Lock Jaw Security is effective AND affordable.
