Your locks are not secure.

Recommended Posts

I seem to have an odd fascination with locks and how they work. I work in a hardware store as their master keycutter. I've cut safe keys that had snapped in half from boat keys that I'm not even supposed to have. The job takes me down interesting walkways where I get to explain the internal mechanisms of locks to customers who think they're getting a secure lock in my store. That's just not going to happen. Anyone who really wants to get in has more ways than you'd think to get into your belongings. Just placing a lock on whatever it is you want to lock, like a masterlock combination lock, is only going to stop a person for a few seconds.

 

One of those combination bicycle locks are childsplay to unlock and you don't even need any tools for it. You can unlock a masterlock padlock using a knife and an empty soda can. It's called a "lock shim." I've had people who were buying boltcutters tell me they've looked it up but were too lazy to make one. Sadly, boltcutters aren't returnable in my store. Too bad for them. There's also a thing called a "bump key" where it's a default key blank with very general teeth cut at the default distances. You insert the key, give it a slight turn, and gently bang the knob repeatedly with a hammer or other hard object. The pins will "form around" the teeth and then it'll just open.

 

Anything that I'm saying here is easy to google for yourself. I'm not ruining anyone's day or suggesting someone go do something illegal.

 

 

Behold. Here we have a video on how to open you average lock with a cat food lid. And a torque wrench and a file of course. It's a lot more impressive if you don't mention the last two things. :P Then here's one opened with a zip tie.

Also, just for fun, here's what the inside of a lock cylinder looks like. It's good to know.

I am a hobbyist lock picker myself. I concur what is being said by @Raijun in that the average door locks are totally insecure and unfit for use. The entire idea of using pin tumblers for locking systems is, in my idea, outdated and makes for a very insecure lock. Commercial door locks have various 'traps' for pickers such as security pins and other such nonsense but are generally just as insecure. Electronic locks are significantly more secure but are far less reliable as electronic components can fail, meaning there is still a need for a key over-ride.

 

While no system is totally secure, I am impressed by the following security concepts:

 

Abloy Protec 2 - A high security disk detainer lock, made by ASSA Abloy. These are extremely difficult to pick, and it is probably my favorite locking system.

EVVA MCS - A high security locking cylinder that uses magnetics. I have not personally put my hands on one of these, but the concept looks solid and rather secure.

EEVA 3KS Plus - A high-security cylindar. I am mainly interested in this for the keyway, but cannot personally vouch for it's security as I have not put my hands on one.

 

There also exists lock shields to prevent physical damage or tampering to actual locking components. I personally like the Geminy Shield for this. As you can see if you google prices, it would be rather expensive to setup protec 2 cylinders and Geminy Shields on, but it provides the utmost security for the paranoid. I am crazy enough to have a lot of these dead bolts, as well as biometric door latches. :)

The lockers at my middle school were such a joke. All it took was a ruler to break into whomever's locker I wanted to. This came really in handy when my friends accidentally locked themselves inside of their lockers. This is a thing that actually happened. Gosh I love my friends. We're a huge beautiful mess.

I haven't picked many locks but the one I could never get open was my parent's gumball machine. They lost the key and asked me to pick it since I'm usually pretty good at doing all sorts of weird things but it had two sets of pins and I could never get both of them to go in at the same time.

I've never picked a lock (besides the 'ol using a card to get back into my house after accidentally locking myself out) but, I definitely agree that a majority of all locks are almost useless. They probably seem intimidating to a normal person, but anyone who can pick a lock knows, obviously, that it's extremely easy to get past them. I've had shifts who are skilled at picking locks (Neal Caffrey) but that's as close as I'll ever get.

Holy crap I had no idea locks were so easy to pick. Like I've seen a many lockpicking videos in my lifetime but I never really thought it would be so easy. Good to know. So note to self, locked houses during a zombie apocalypse are fair game!

 

How are the chains on doors? I know there are ways around them but I imagine that when someone picks our lock, unless they're a very skilled burgular which I would imagine would completely avoid our houses because it doesn't look like we have much at all and aren't in the richy neighborhood, would pretty much alert us when they go to open the door and we hear the chains. As an alert system, I don't see them as being the worse but as a hey burglars you can't get in here system, they're pretty easy to get around.

A lot of these effective defenses work best when you're already on the inside of the house. :P A chain across the door is only as strong as the door's hinges that can withstand a heavy force. Imagine how strong a window would be if someone wanted to get in. It's glass and a fiberglass or aluminum fabric. Big deal. I break those by accident.

 

Also view the

and the
videos.

 

I find them awesome yet disturbing. Very intimidating to conceptualize.

I have had 3 bikes stolen over the 4 years I went to college. I've had the best luck with a combination U lock. Must just be luck after seeing the video. lmao

Safety in a house is such an illusion. If someone really wants in they will get in.

I had a guy walk in through the front door, past my room mates and directly into my room. He had an attitude that he was supposed to be there and they never questioned this strange guy. I had to talk him out of the room and escort him out of the house.

Good to know. The last thing I need is someone breaking into my apartment. Fortunately, there are two doors they'd have to get through. But these locks are old fashioned and not all that great. They get stuck far too often. At least I know that nobody's going to manipulate my buzzer; the people who are hired to fix it can't even get it to work.

By the way, just for kicks and giggles, I just had to use "that old credit card trick" to get into a building that an old family friend had locked himself out of. It was exactly as simple as it sounds, and I'm sorry that that's how simple it was. It saved us a night of aggravation, but if it wasn't someone with good intentions, the lock is still super-easy to bypass. What a shame.

 

So don't forget your keys. Hide a copy in a really really weird place; somewhere nobody would ever even begin to think to look. Though the best thing to do is to not hide a copy of a key at all. Give it to your neighbor to hide, and have him give you a copy to his house. Mutually assured destruction.
