Not with one of these cheap and awful master lock padlocks. I’ve seen people pick, or more accurately rake, them open in about 7 seconds. Not sure about he door bolt though.
Well they did say it requires about 5 minutes in nitrogen to cool the metal down enough fot it to be that brittle, but also the argument could be made about picking the door lock would probably be faster, as well as cutting the shackle on the other lock, it is still recommended not to do so for any other reason than testing, showing off and most importantly, with locks that are put in places only for said demonstrations.
I got that. I'm just saying that pouring liquid nitrogen on a door doesn't attract as much attention. I mean if you did it in the back yard with a privacy fence no one would notice that part. But people are going to hear BANG! BANG! BANG!
matter of fact, you dont need the gloves for anything really other than to hide your fingerprints at most, liquid nitrogen slides off your skin faster than it can burn you, unless it gets stuck say in a crevice if you were cupping liquid nitrogen in your palm kinda deal
Dr.Halloween Even that is fine in most cases (leidenfrost effect). there are rubber/latex/whatever gloves made for handling such cool liquids and esp. metals which are a good idea. because if you cool down say a lock or other metal parts and touch that, it will cause frost burns pretty damn fast
As I recall the reason to use CO2 to break a lock had nothing to do with time, but sound in fact after you freeze the lock you want to be careful what instrument you use to "break" the lock cause while the liquid Nitrogen does give you a quieter way in if you use something too heavy it makes a loud sound and you just defeated the purpose.
they do have custom cylinders that inject liquid nitrogen into the lock cylinder for the sole purpose of super freezing the pins, at which point you insert the forged shim attached to the cylinder and snap/twist to the right or left. the pins shear and the lock just becomes a pretty accessory.
I'd like to see a race against an experienced lockpicker. Chances are, a lockpicker could make it through in even less time than even the brittle-ized lock. Heck, even a bump key would probably be faster, if it works.
surely they did try it on a flimsy door and yes, kicking it in would've been a lot easier. but what about security doors? my idea is that the locking mechanism is still way more fragile than the door itself, at that point, thinking to bash it once froze over, it's not that much of a crazy idea
nuutti tuulosniemi, freon is only cold at liquid state. once exposed to oxygen or air, it changes to a gas state. and the gas state is actually hot. freon is only cold as a liquid. that is why for example a outdoor ac unit on a house blows hot air out of it to change back to a liquid. just thought I'd share that.
I'm surprised they didn't try the drill method. If you drill in the right place with a hardened drill bit, you can destroy the tumbler mechanism and just use a flathead screwdriver to turn the lock.
Kari: Yeah, it’s probably not gonna catch on. Mr. Freeze: Woah, watching that gave me *chills*. That’s a *cool* idea that will let me break the *ice* on my next *cold* caper.
5 minutes and 37 seconds without liquid nitrogen and 1 minute 4 seconds with, but they failed to add the 4 ½ minutes of exposing the lock to the liquid nitrogen! Anyone using liquid nitrogen to break in through a lock would have to include that time, because the locks obviously don't come, "pre-frozen," lol so they should have included the freezing time to their overall test times here, too.
1. thermal insulated vat of liquid nitrogen 2 .large amount of safety stuff 3. on for 5 min 4.3 people suck that 1. like 1 or 2 cans of air 2 .welders gloves or leather gloves 3 turn upside down and spray 4 just you
They do know that there’s a difference between picking a lock and boot force opening a door right, I was expecting them to do a control of someone picking a lock with a lock picks
How are they not counting the time it takes to use the liquid nitrogen? How is that a fair test. Lets just ignore the guy standing at the door with a tank of liquid nitrogen for 5 minutes until he hits it with a hammer then we will get suspicious
yeah that is exactly what I was thinking, the application time should be included since it is part of the process. unless you can get it opened without making the same loud sound there is no point.
I had my magically delicious Lucky Charms locked up and someone stole all of it by using this damn method... thanks, MythBusters, Now I will starve to death.
You're missing the point. The question was not what's the best way to get through a locked door, that's with the key. The question was will freezing a lock make it easier to break.
How is this confirmed? The control took 5:37 seconds. The final test took ~6 min counting the time for cooling the lock with liquid nitrogen & actually breaking in.
Iosif I Why not? The time it takes to cool the lock adds to the total time it take to get through the door. Oh I think the proper protocol calls for me to make some insulting comment about your intelligence now in response to your comment. However I just don't care.
mkohlhorst The reason you don't count it towards the time is because these procedures don't really make any noises. As someone living next door the first thing you would hear is the first hit with the hammer and by that time the lock is already shattered. I guess if you just want to run in and steal some guy's TV, a 2-3 minute advantage is a pretty big one.
argh1989 If I was living next door the first thing I would notice would be 3 people dragging a heavy clanking gas cylinder up to the door. I think if it was me I'd go for the window instead.
Lol, Kary said did ductility. I think what she was actually thinking of is malleability. Ductility is the ability of a metal to be easily formed into a wire.
I used to work as security at a car dealership in the new car storage depot. When I locked up, it was only a single large padlock for the gates. Although there's CCTV, it wasn't monitored at night. EASILY break in now! We stored Porsches, Saabs and Audis. Petty I can't afford to be caught but for those in a life of crime....very tempting. Not to mention that as a minimum wage security guard, I had access to ALL keys, including the cars.
Masterlock can be picked that fast, without evidence of tampering (see @BosnianBill videos). Pity they didn't choose a lock with a better reputation for quality, as opposed to just one with a reputation for cheapness. And despite their electric tape attempts at hiding the brand, yeah, that first one had to be Masterlock.
In minus 50 degrees Fahrenheit the lock on my 53 foot dry van froze and the key would not work. Customer was waiting to get the parts I had on board to mlm eet a deadline. I took an 8 pound hand sledge hammer and broke it off. I hated -50. This was outside Chicago and I'm from the Pacific Northwest and it don't get that cold here!
I knew the myth a bit different. If you use a deodorant, so it goes, and you freeze the loxk with it it would become brittle enough to shatter when you smash it. I wished they had tried it with this method as well, since this is a totally possible and cheap way. Getting your hands on liquid nitrogen and transporting it to the object would not only be pretty expensive and difficult but you would be stopped by suspicious cops in action. It's not very unobtrusive
You do not need any of those things - a can of pressurized freon is the choice tool. And you use a different kind of pick. A poorly trained burglar can go through a like in about 15 seconds and a well trained guy can do it in under five. The bigger the lock, the easier it is.
I wonder how PAYDAY 2’s take on the myth would hold? Drill two holes in a bank vault door, fill the holes with liquid nitrogen, then detonate them using C4. Ah, who am I kidding? The drills would keep jamming. Busted.
Is there a reason they aren't counting the 4 minutes it takes to introduce the liquid nitrogen to the lock in the time it takes to break open? both times they said "oh it's so much faster" having taken an extra 4 minutes already on top.
ok, all you have to do is break the outer shell, then put a number 2 philips screwdriver in the hole where the deadbolt tailpiece once went through and turn it to retract to bolt.. use of unecessary force once the outer shell was gone.
Grant is wrong about all but one of his reasons this in impractical, you do not need safety equipment (at least not any more than you should have when not using nitrogen) you do not need 3 people, you do not need a giant vat of liquid nitrogen, just a thermos. His only valid argument is the time it takes to use the nitrogen
if you liquid nitrogen in a can, just get a air spray, they clean the dust from the older keyboards, turn that shit upside down and boom, liquid nitrogen, plus its not just on the outside. you can spray it directly into the lock and it freezes both sides instead of one side like this
how is the myth confirmed with liquid nitrogen and the deadbolt? It took ~5.5 minutes to break the lock at normal temperatures, and with liquid nitrogen, it would take 4 minutes of pouring PLUS ~1.5 minutes of hammering. So, it takes the same amount of time to break the deadbolt.
There are associations which do lock picking as a sport and can open regular cylinder locks in less than a minute without breaking the lock, using a hammer or even nitrogen seems like a pretty clumsy approach. The nitrogen-method may be the faster brute-force method, but it doesn't beat a burglar with the right equipment (which fits in a pocket, unlike liquid N2) and some training.
+Radonatos +Atl essa People would be shocked if they knew how easy it is to open a lock. Several seconds of jiggling a skeleton key along with a twisted L pick.
+Radonatos Burglars don't seem to be keen on "fidgeting" with a lock at all. I'd say they go for the MUCH weaker points (e.g. a window left unlocked, also a window frame in a hard-to-see spot of the house is almost always easier to pry open than a door). The only people who would take the pain of picking the lock would be private detectives and secret agents i.e. anybody who would want to hide the fact that they've been there and perhaps locksmiths (the police wouldn't do this, they always come with a warrant and besides they're too dumb and inept for this technique anyway).
I wonder if by spraying the liquid nitrogen into the lock, if you could unlock the door forcefully with a flat head screw driver. Using a compressed air canister would be really easy to spray the liquid inside the lock (they usually come with a small straw like nozzle)
Complely disregard the last part....you can get a can of that key board cleaner stuff....its liquid nitrogen...get a glove or even a sock if need be...and spray on the lock for about thirty seconds....and hit with hammer....and u have to turn the can upside down for it to work this fast.....and DO NOT SHAKE IT BEFORE USING IT!!!!!!!!!!
Ok so the first time on the door lock they had 5 mins 37, but the second time they needed to use the liquid nitro on it for 4 mins and did another 1m04 sec, so if u take the 4+1m04 its kinda 5m04 instead of 1m04, so it's not even close to way less then half the time :p, it's only like half a minute faster not to mention carrying the liquid nitro around and their safety suits. I dunno, but not rlly convinced about he faster lock picking.
This myth is not totally confirmed. You had to expose the liquid nitrogen to the lock for 4 minutes, plus you could tell they had set up a small basin so that it could soak in it. Doors don't have those, so you would have to sit there for upwards of 4 minutes, constantly pouring liquid nitrogen over the lock before you could even attempt to get in.
I only ever watch Mythbusters after the fact, but why are the two main guys sometimes gone and they leave these interns to do episodes? Is that why they got canceled?
of course lock making companies arent concerned with the pins, theyre just concerned with the exoskeleton, since this nitrogen method isnt used by the normal burglar. i prefer lockpicks and the timesaving "raking method"
because freezing isn't loud, as soon as you make much noise they expect that people get attention towards the noise and eventually call the cops after a time, that's why your car does not explode when opened without the key but makes big ass noise
In addition to the explanation given above, I think they mentioned that they soaked the deadbolt for 4 minutes. So, even if you include that time, it totals to 5 minutes and 4 seconds. Still quicker than normal.
Exactly like you said though.. That's not the average person, nor is it the average burglar... So how is any of that a real threat? Liquid Nitrogen wouldn't work for those types of burglars because they are going after the types of people who use locks that are resistant to it....
They should have a compressed nitrogen pump that gives deep into the lock. Then i bet if you snap something sharp into the keyhole, you can break it silently. But its not a good idea for a television show to give ideas like that
