I thought lock bumping was bullshit till I tried it on my doors. I bought better locks I seems medeco are the only locks that cannot be bumped and they are like $150 each minimum. Generally, any Assa Abloy lock is light years ahead of the traditional American door lock. |

Bilock.
http://www.bilock.com/doorlocks.html 1) They don't sell blank keys. 2) Scumbags can't swipe blanks from the local hardware store. While you're replacing your locks, replace the hinge and lockplate screws with stainless screws at least 3" long. Makes the door a little more resistant to 'door bumping' with a boot. BSW |

Alarms help with lockbumping too, they may open the door but the neighbors and the cops will know about it.
Best bet is to upgrade the locks with those $150 ones that are imervious to bumping AND get an alarm. Crooks will probably just walk next door and hit your neighbor that didn't do anything to protect himself. |

Ok, I'll be the first....what is lock bumping? Lock bumping |
This really reminds me that when it comes down to it, people are all pretty much on the honor system. It wouldnt have occurred to me to try to do that....since as the rightful owner of locks, I have the keys. Fucking criminal swine....(off to check my locks)

Thanks for posting this. I wasn't aware of it, and it's a good thing to know, both how to stop it and how to do it, if necessary. Is possession of a bump key illegal, as in possessing an 'instrument of crime?' Can be... though some states may have to prove intent. If you do get a charge, it's considered to be "possession of burglary tools." As far as the technique, it's been known to locksmiths and professional burglars for decades. It's dead-easy to do, and defeats the vast majority of common locks, particularly on residential homes. This is the downside of open-source information; trade secrets and weaknesses like this get disseminated to those who would misuse them, but would otherwise not be motivated/smart enough to seek out the knowledge on their own. Residential locks that are resistant to bumping don't have to be big bucks... the Smartkey series from Kwikset is reasonably-priced, and bump-proof. 
Those are mine... they're Bilocks, and they're all installed now. I got some grade-1 deadbolts (for exterior doors), and some grade-2 (for some other doors). |

I just bought a new lockset for my new front door. It was a kwikset and it was advertised as bump proof, but it was one of their more expensive sets.
ETA: it was their smartkey series http://kwikset.com/smartseries/smartkey.aspx |

Medeco or Primus. Once again, controlled keys are a plus. Although for the former, just found this on teh net.  , In addition to Schlage Primus, they recommend Kaba, Assa, Abloy, Mul-t-Lock.

It looks like the kwickset smart key models will do the job when it comes to keeping amateurs out of your home. I just did a preliminary search on the net, and it would appear as though they are very affordable in comparison to others listed in this thread. Yes... the Kwikset locks are very affordable. They're about half the price of the Bilocks... which are themselves almost half the price of the Medecos. |
| Locksmith chiming in here. Medico Bi-Axial and Schlage Primus with pattented/restricted keyways are the only way to be sure, however if your door and frame are not steel, a kick will het them in. Likewise windows are a weak link as well. Not to mention the cost of said systems. I still have the Kwickset locks in my house that it came with, even though I could have Primus cylinders and keys for free. I can not afford to harden the house against all other means. |

Most shitty locks sold here probaly aren't even able to be sold in most 1st world countries.
FWIU- In European countries the insurance compaines won't write you a policy if you don't have good locks and doors and frames. $15 kwik sets that can be-literally- picked in 5 seconds won't cut it. |

It's better to go with a whole-system approach. It makes little sense to spend big bucks on your doors, if there's a non-impact-resistant window five feet away. |

If someone is caught with one the cop "should" be able to articulate possession of burglary tools as that would be considered a burglary tool just as easily as gloves, screwdrivers etc. |

I agree, but:; My goal isn't to keep people that REALLY want into my house out, that's pretty much impossible. My goal is when the tweakers drive by looking for places to break into, they see my neighbors with locks that wouldn't keep out a angry toddler and that my front door doesn't have the same carp lock on it.

BSW The tweakers are simply going to kick in your door. They're more brute-force type 'o guys, eschewing even the minimum of finesse that lock-bumping requires. I'd say that as long as your frames are reinforced (strikemaster), your locks are quality (see above), your doors solid wood or steel, and your windows reinforced with mylar (armorcoat, 3M, etc), you've done all that can reasonably be expected to reinforce the exterior of your home (and not have it look like sh*t... because let's be honest, the wife has to like it too). If some guy has to spend five minutes bashing down your door, or completely obliterating your window & frame (which makes a hell of a racket, and is likely to be noticed by your neighbors), he's more likely to give it up and go elsewhere. Then again, nobody ever said tweakers were creatures of logic and reason.

I saw these lock bumping videos on youtube a couple years ago when I was searching for a good chain to lock my cycle.
Then last summer I go outside to mow the lawn and by habit locked the door between the house and garage "shit!". I normally keep a spare key in my wallet but it was in the house. I tried pushing and prying on the windows and doors as much as posible without breaking anything to no luck. Finally I remembered the bump videos I thought I would give it a try before breaking a window. I found an old key from when I put in new locks, used my bench grinder to grind 4 or 5 saw tooth shapes into it, I couldn't remember the exact pattern but understood how it worked. I lined my new key up in the opening, tapped it with a mallet and twisted at the same time, it took about 4 trys to get the timing down before the knob turned. I thought wow a vague idea of how it worked and literally 2 minutes of time and the door was unlocked with out a sound. I then searched the garage for any extra key shaped items and pitched in the garbage. I already keep my safe cracking tools -angle grinder, 2 die grinders, and big pry bar- in the safe, my bench grinder won't fit, I try not to supply criminals with tools. Until I put bars on the windows I see no point in spending $400 for bump proof door locks. |
