This lock can not be opened even with a key!

Good day, dear the inhabitants of our site!
In this article, the Lefty channel will show the whole process of creating a lock with a secret.

The author will make a small padlock, it is easy to open, but you need to guess how.
The author will make some of the details himself, and part will be taken from a ready-made, purchased lock.

The body will be made of aluminum ingots.

The uneven edge of the blank is grinding.

It will consist of two parts, with milling inside.

From the side of the future bow, part of the body must be cut off. For this, a disk mill is installed.

A milling superstructure is also installed.

In the add-in, it clamps both halves at once, because they must be the same.


And cuts off.


The end mill marks the places where it will be necessary to grind a groove for the arch.

In a cartridge with independent cams, the part can be shifted relative to the center.

In each half of the body, a groove is pierced by half the diameter of the arch.

And trying on a bow.

When the lock is closed, it seems that the handle has a standard U-shape.


The author traveled around the city floor and found such a welded stainless steel ring.

It must be carefully cut at the place of welding.

It was not so difficult to disassemble a store padlock. It is necessary to drill several holes from the end.

After that, the entire mechanism is removed from there.


From the purchased castle you just need a larva. This is the part into which the key is inserted.

And for her, a hole is drilled in the bottom of a new building.

The key hole in this case is only required in order to confuse the cracker.
And the remaining details of the mechanism are essentially not needed. Therefore, the back of the locking mechanism - the larva - is drained.

For the stopper, in the back of the larva, an annular groove is pierced.

In one half of the body, a recess is milled into which the stopper will engage.

It is needed so that the larva does not fall out, but rotates, thereby simulating the operation of the mechanism.

Trying on the larva to the stopper.

And in this place there will be a real locking mechanism. But it will be completely hidden in the case.

A part is turned out of the metal that is magnetized, which will be a stopper for the bow.

Establishes a spring and a stopper in their place.


The most difficult moment here was to pick up a spring of necessary rigidity. Closed state.

Under the influence of the magnet, the spring is compressed, and the stopper sits lower.

Then the bow - the ring rotates.

In the key, drills a hole for the diameter of a small neodymium magnet.

Replaces the magnet. Thus, the key will perform its direct function.

The author trims the larva a little.

And he drills holes for the screws holding two halves in the body.

It cuts the thread, checks all the holes so that there are no displacements.

Of course, the body could be welded and glued. But this is still a decorative thing, so the author used small cogs.

Next, takes sandpaper, which must be used with water.

And polishes both halves of the case.

The emery paper is fine-grained, therefore it is polished for a rather long time.


Now the assembly process. The author makes it beautiful and neat.



It remains to insert and tighten the screws.


If desired, can be varnished, or painted. All is ready.

It remains to test. The first thing that comes to the head of a person who tries to open it is to insert a key into the keyhole.

But no matter how much he turns the key, the lock will not give in.
Even if he realizes where and from which side to put the magnet, it will still be necessary to understand that the handle is not pulled out, but rotated.

It turned out such a working decorative thing.




You can play a trick on your friends by making them a puzzle, and even by handing a key.

The manufacturing process of this exclusive castle, and the castle itself was created by the Lefty Canal.
All good homemade!

two wrenches needed =)
"This lock cannot be opened even with a key!" Yes, yes, of course, unless it’s a wrench!
First of all, a thing must fulfill its task. And high enough for the effort.
The first thought about opening such a lock: take hammer number 4 and beat it well. Thought number 2: take the shape number 3 and unscrew the fuck arm. Or thought number 3: take the grinder and cut off the arch. In general, the idea did not come to shove at least something in the guise.
The screws in the case are brilliant. Neodymium magnets are kilograms in all corners. Easier than simple: twist, saw, grind, drill, spoil a normal lock, find a magnet.
it’s good when VEB is a company, and a priest went to our friends and rang all the doors of the house. Let me dedicate a hut to you.
You understand the trick of the plan:
1- looks at what is in someone's apartment;
The last 2 priests can be suspected of something;
3 people almost never refuse to consecrated apartments;
4 - it is customary to pay for the dedication;
5-who is not at home can also be recognized;
6 shows how many doors you have and what locks with a frame.

After there was a surge of thefts, one door was directly knocked out with a frame box. Slightly moving away from the topic, we talked about how cars steal, a "type" tow truck arrives in a crowded place stupidly loading an expensive car and goes "type" to the penalty area
Now, besides the “fomka,” there are so many means of “small mechanization,” they will press any door!
"But all this was in the 90s !!! Now that mess is gone!" Maybe you don’t, but we have enough! Recently, a Gazelle drove up to our house, the entire tent was covered with logos, phones, WEB addresses of a certain company, the guys went out in corporate overalls, went around the apartments, offering business cards and services for repairing or replacing locks and doors (and at the same time studying them!) .A day later, "carried out" several apartments! One of the neighbors then said: “I see yesterday’s guys messing with Lyubkin’s castle, I thought they’re changing”!
I agree with you, but only partially!
1. No doubt, the author is well done, hands are growing where necessary and are friends with the head, respect and respect!
2. We do not discuss everything, but only a specific homemade product!
3. "It was not so difficult to disassemble a store padlock" Estimate the approximate cost of homemade work, including the time spent!
4. "Any castle is, first of all, a PSYCHOLOGICAL BARRIER !!!"
5. Well then, "What the hell"?
< "Фомка" называется. Видел как фомкой...>
Is it a nail puller (vyderga) shortened, or what? So I will disappoint you - you won’t do anything with a steel door. A Ketai canned steel door can be opened with a can opener. derisive

I have two. plus two crowbars. anyway, for U-shaped locks there are two keys on 22. and there is no lock
if interested - google. I'm not writing advertising for vidos here.
Author
not even a Bulgarian is needed. two keys on 22
There is such a device, "Fomka" is called. I saw how a metal entrance door with very powerful expensive locks was rolled up like a tin can. The lever is a superpower!
<За девять месяцев этого года в Новосибирской области совершено 1 400 квартирных краж, из них в Новосибирске — 769. Статистика по этому виду преступлений идёт на снижение несколько последних лет. Основная часть краж совершается в дневное время, когда люди уходят на работу, а летом — в выходные дни, с отъездом жильцов на дачу и в отпуск. Самый распространённый способ проникновения в квартиру — подбор ключа к замкам, причём в основном китайского происхождения. На втором месте — кражи с проникновением через пластиковые окна, когда отжимается одна из створок, чаще от этого страдают квартиры 1—2 этажей, хотя случалось, что преступники пользовались альпинистским снаряжением, чтобы спуститься сверху. Разбивают окна воры в основном в частных домах и сельской местности.>
And yes, they slowly transplanted. Now at night they throw cars near the house. And the nearby car parks (paid) self-destructed.
They steal mainly in new high-rise buildings.
But all this was in the 90s !!! Now there’s no longer that mess! When was the last time anyone heard of a real apartment theft, for example? ...
What for, if the penny “in a plastic case” copes no worse!
Well, if you think so, then most homemade products will not exist ... There is an interesting, non-standard solution. Already for the sake of this it is worth doing ...
"It is amazing how people attacked the author for the" weak design "....
It turns out that, for example, small locks in a plastic case do not make sense at all? ... And who buys them then ??? "
You yourself answered the question! What for, if the penny “in a plastic case” copes no worse!
And we did not save the iron bars on the windows either - they even broke them out!
Uncle told how they stole in the “stormy” 90s, in a summer cottage they opened all the dachas where there were padlocks, he also broke a barn lock, but they didn’t open his cottage, what do you think that stopped the thieves? They were stopped by an ordinary internal castle, but that's another topic. Taki when to do something seriously and honestly
An ordinary lock should somehow protect against petty hooliganism.
In Siberia (especially non-contemporary), at the entrance to an apartment building, the mailbox doors are cracked. My father-in-law strengthened the door and added a lever on the latch. And we are always closed. Playful little hands can not be opened.
Wait, there is an iron door with an intercom at the entrance and on the landing already more than order.
But in essence ... It is amazing how people attacked the author for the "weak design" ....
It turns out that, for example, small locks in a plastic case do not make sense at all? ... And who buys them then ???
People! Any castle is, first of all, a PSYCHOLOGICAL BARRIER !!! You can open, cut, hammer down ANY !!! ... The only difference is that for one you need a grinder, and for the other - strong hands !!!
And you need to choose a castle, based on the fact that he is obliged to protect !!!
I think no one will argue that the barn lock with which the "dogs" of lightning on the suitcase are connected will cause bewilderment ... Like the plastic combination lock on the garage doors ....

I'll be honest. The topic of seals is not disclosed =))))
I’m already old, life has taught compromises, let it think that it’s the main one, but only for cats! She is afraid to share the fate of kittens! scratch
Korolev,
smile
It is necessary to declare your dominance in the family !!! Let me know WHO IS HOME IN THE HOUSE !!!
I kind of once knocked my fist on the table and showed who was in charge .... So then I CROWNED ON ME ON KNEES !!!!!
smiles smiles
.... Get out, he says, from under the bed .....
But here I did not give up !!! ....
I say I'm the master of the house !!! WHERE I WANT - THERE AND LIE !!!!

Unfortunately my "grandmother" with the "wrong concepts"! She has cats first, then me!
And mine, the infection, does not eat raw, you bastard! Him - cook and choose the bones! Aristocrat of horseradish.


I once took one such "aristocrat" from neighbors who did not know where to put it (because they could not contain it), and took my grandmother to the village. She, on the contrary, was looking for a "cat, more mice tortured."
... I myself watched a couple of months later, as the "aristocrat", shy, stealing a soaked bread from a tub with slops with her paw ...))))
P.S. Grandma was with the "right concepts")))). "If you feed a cat, what good is it? !! He has to catch food for longer !!!
"My cat will open if the fish lies behind the door"
And mine, the infection, does not eat raw, you bastard! Him - cook and choose the bones! Aristocrat of horseradish.
It is evident that the author tried, but without a lathe weakly?)). The idea is interesting, but aluminum and stainless steel (except for A4 and the best), the thinner the ring, not the hard metals, you should use hardened steel (to heat when all the parts are ready). At the expense of what they don’t open, the key snag must be at least three different and so they spin tight. It is enough to give out a "secret" with a magnet and a "word of mouth" ... all and sundry will open. My cat will open if the fish lies unattended behind the door))
and people say ........ against scrap there is no reception, but the idea itself is certainly beautiful
Author
Exactly. Wet software how many protections did not come up - even before the release of the off version - already crack is lying in the public domain
My grandmother said that all castles from honest people, no castles will save from crooks!
In my basement the closet was locked. Put a code lock with wheels (with digits). I myself "picked up" the lock code for operation ...
I thought they wouldn’t pick it up ... In the 90s, age hooligans were opened in our basement. They simply pulled the lock and the handle moved slightly - and openly. They stole a duralumin ladder (metal), trans.welding from 2 LATRs (they just did it, they haven’t tried it yet!) ... And on the other locker I had an ordinary monolith lock. They twisted it, turned it with a small crowbar (they took it in one of the rooms) - they bent the arch slightly. Do not open!
Author
The lefthander wrote - purely DECORATIVE
Screwdrivers are superfluous here!
It was necessary to consider a monolith, then yes!
How interesting the idea is, but reliability is not ice, since it won’t work against scrap, people with lowered social responsibility will turn out two times! :-))
