I'm curious if the use of a 7 pin was to match keways and or master keys in the facility this came from, so this lock could have 7 pins but no other security features, and other security features be included on other locations needing more security vs safety while keeping the total keys needed down
Are there any locks that have a shitload of pins? Like 10, 15, 20 pins?
It's a gate lock, the residents see thru the CCTV , who had rung the bell , and push the button , the mechanism inside the lock receives the signal and the motor whirrs the lock, secondly push a mechanical button right at the lock from inside the door, thirdly use the key from outside ...
The real question is: can you defeat the full interlock system with it hooked up to properly work and installed in something so you can't 'just' reach behind it and manipulate the solenoid with a finger?
And as always have a safe lock… ⬅️ this is what you should say instead which I think is impossible LPL is the GOAT
Nobody: Lpl: I don't know what this is but I'mma pick it :)
Dear LPL, my partner is a local locksmith in the area we live. His name is jake, and you are his favorite channel and he loves watching your videos, his birthday is today (12/13) and I think it would be amazing if you could shout him out on one of your videos! We love watching your videos and even if you don’t do a shout out we will still be subscribers lol have an awesome day
If a lock ever sponsored him, it'd have to be unpickable.
Straight forward lock but I do like the way they made all that work. Even the machining in that arm to throw the switch is cool. Looks like it would work without fail for many years.
I bought the covert companion, and you should make a video using each of the 20 picks in the set. And explain what locks each pick works with
It's for alcohol breath test, unlocks vehicles ignition if blown under limit..
Those are used in Maintenance bypass setups for low voltage switchgear. I see them in almost every piece of gear I put in! Not really for security but for preventing dumb people from doing dumb stuff. Basically in normal operation the load is always through the ups, but to get the load off the ups to work on it you first go through a shutdown op on the ups, that releases the key, and you can close the breaker to tie utility to ups load, then you remove the ups from it by opening the breaker and removing the key and putting it back in the key interlock.
Probably off an American stamping press that had been sent to Mexico, where safety devices are not required.
You could chain these together and have a multi-part system with a required start order.
Brings me back to my old warehouse job... nobody liked climbing in the baler.. LOTO FTW
7 pin might be to ensure uniqueness of the lock cylinder.
why not make these kinds of locks just function off handcuff keys?
As someone who has never picked a lock and only watches these for entertainment, this lock had some of the most satisfying clicks I've ever heard.
For anyone interested, the lock is a Kirk SD SERIES Type SKRU (Solenoid Key Release Unit) By default, the solenoid is de-energized (Plunger Down) locking the key in place and the Toggle Switch in the ON position. The solenoid is connected, in series, to a (Normally Open) Push Button, when the button is pressed, it closes the NO Gate, which completes the circuit and energizes the Solenoid, raising the plunger and enabling the key to be turned and removed. You'd probably find a device like this on a standby/backup generator that is energized, but in a standby state waiting for a load to be requested. www.environmental-expert.com/products/kirk-model-sd-series-type-skru-solenoid-key-release-unit-498518#:~:text=KIRK%20%2D%20Model%20SD%20Series%20Type%20SKRU%20%2D%20Solenoid%20Key%20Release%20Unit,-From%20Electromechanical%20Interlocks&text=The%20Type%20SKRU%20consists%20of,to%20an%20external%20electric%20signal.
Yeah instead of using a key at my college we use a screwdriver on one of our robots
Is this even a lockpicking video anymore
I work for GE renewables and we have a very similar lock system for Medium Voltage Switch Gear on our 3 MW wind turbines. And the electrical part would usually trip the switch gear and throw a safety chain fault cause the tower to go into a safe mode. But the only way to get that first solenoid to move is by shutting it down and going through multiple steps to put the tower into a safe mode so that you can access the compartment that houses the switch gear.
*click* me at 3am: whats that noise? lpl: click out of 4, and we're in
Demonetize this guy
Nuclear launch locks being replaced this week :)
Didn't pick the solonoid 2/10
lets see that stuff brand lock!
How are your videos not monitized, UZload give this man some money.
You'll see these in manufacturing when safety is a concern. For example it's possible that was connected to a gate or shield that needed to be down so the tech would be protected first. Then he could access the key and probably enable operation of the machine. If the safety sheild was up and the station was not safe, it wouldn't allow him to activate the system.
I have seen this kind of interlocking device on substations, to prevent the user from doing dangerous manipulations. See : uzload.info/fun/f39naXKozrFnu4k/video
"What this was used for." One of the most obvious security functions. Human supervision of an automatic process. The input signal would trigger an action, but an operator is required to confirm the action. The operator cannot trigger the action by himself by just flipping a switch, the input signal is required.
These are common on freightliner step vans that FedEx uses. Probably what this is off of.
Can’t wait till he starts picking biometric locks
He’s got some meaty hands but delicate at the same time
I just noticed that it would be a lot more illustrative if you were to show a representation of what you're moving around inside the lock with a simple 2 d drawing
Activate interlocks, dyno-therms, connected
It's crazy how fast and experienced you became in only a few years! But seriously? Do you feel safe in your own home, knowing, that any lock can be picked? 😅
This was probably a prototype/proof of concept. I worked with a few large machines and all doors were secured with locks just like this one, the switch thrown by the mechanism functions as a redundant emergency stop to ensure nobody can bypass the open door and turn the machine on, since a person could be inside. They're usually dressed up in thick plastic and have a more industrial looking key
for train man for train to lock high voltage and low voltage on engine compartment uzload.info/fun/lquofn-q2m-Em5s/video you can take only one key from panel if you want take black key you need insert blue and blue key is use for start a train
Ooooo, I might actually have an idea on this one! As a controls engineer, I have some experience with this type of stuff (albeit most stuff has specialty hardware for applications like this). My guess is that the solenoid would be used for checking if a high speed motor is spinning. On some grinder systems, it can take upwards of 10-30 min to stop spinning after you stop powering the motor, and hooking the solenoid up against the motor (checking if it is acting like a generator) would allow you to ensure the motor is actually stopped before the key can be removed, and the key being removed could then disable the start signal to the motor. That may not be it exactly, but I would bet significant money it has to do with some physical force acting on an electric system via momentum, could be something flow related as well acting off pressure or even temperature related.
Such devices are in use also in (petro)chemical industry, in continuous processes, where you dont want to shutdown everything, bc one part has a (hopefully) temporary problem. For instance, a number of cracker installations, feed a compressor, that feeds a cold section, where fractions are separated. If the compressor trips for some reason, you do not immediately shutdown the entire factory, bc that is very costly. An electrical detection gives an electrical signal to your key, which can then be turned to allow another electrical signal, which opens valves, which directs cracker output from the compressor to a flare. You wouldnt want the key turned in normal operation. It will usually be an emergency operation that can be automated, but the key is leaving a human decision in the chain.
I imagine this being on a box baler or garbage compactor where you press a button and turn a key
I work for an electric utility. We use these in substations on high voltage circuit breakers. The breaker has to be open to energize the solenoid to turn the key. The contacts stop the breaker from being closed electrically with the key removed. The key can then be moved to allow a manual disconnect switch to be opened. We don't want these switches to be opened under load and having that key in hand means the breaker is open, therefore no load on the switch.
Cant wait for you to try stuff made here lock
@ UPVOTE THIS! COLAB NEEDS TO HAPPEN!!!!!
@ UPVOTE THIS! COLAB NEEDS TO HAPPEN!!!!!
I've seen similar things in an icecream factory I worked summer-shifts in back in the day ('96-'01). Huge stainless steel cauldrons of fast moving mechanical parts that need to be cleaned every day, but have no way to be disassembled properly without being busy for hours, so only the bowl is removed with the moving, mixing parts attached to the machine. You disengage it from the mains with a key. I remember the slight humming sound when operating the key(s), probably some arcing effect.
So that's where my car lock weeeent
The real security is the fact that if you tamper with the device you’ll violate the terms of your release
Your a lawyer? How would one request services, or even ask what field to know its even applicable to ask?
I'm going to imagine he just wandered into an electrical substation or something, saw something with a lock on it, and in a couple seconds flat the lock, locking mechanism, and lockpicking lawyer were gone
This should be a part of a 2 hand startup procedure to prevent unintentional startups. One hand is used to press a button that powers the solenoid while the other hand is used to turn the key.
If I had to guess that would have been one half of a set of two identical locks. One would be the “Lockout” and the other would be “Operate”. When you want to start the device you turn the “Lockout” key off (throwing the switch) which unlocks the Solenoid on the “Operate” switch, you then take the key from the “Lockout” switch and transfer it to the “Operate” switch then turn on that switch which would engage the Solenoid on the “Lockout” switch so it couldn’t accidentally be engaged. I saw something similar in a Power Substation once, however that one also was a mechanical lock to prevent the door from being opened while the station was operating.
You know how people say "have a nice day" so often that you just don't even realize they say it and you're like "yeah you too." It's just politeness and they don't actually care if you have a nice day and you donut care if they have a nice day either. But for some reason today watching this I actually feel like you actually are wishing us a nice day. And I really needed that. Thank you LPL for wishing us a nice day. I genuinely hope you also have a nice day.
Ok he just saw this one on a door somewhere and took it when no one was looking this it what it looks like here 🤣
You never fail to amaze me. I never thought I could be so captivated by watching someone open locks. Thank you for the entertainment.
We see interlocks like that on 13.800V gear here, you have to shut the section off, before the key will work, and the other switch will not allow current to allow you to pump it up and close the circuit until the door is closed and locked, have had to "by pass" a few over the years to troubleshoot equipment.
Didn't pick the signal to the solenoid? Part of the lock, no?
I'm not a racist because I own a color TV
this just popped up in my notifications tab as "uploaded 12 minutes ago", anyone else?
My guess is the solenoid was also connected to the machines main power, when power was on you couldn't use the key, when power was off the key could be used.
Ahhh Yes @LockPickingLawyer The infamous “Kirk Keys”. So if you don’t know about this company go check out their website, their product is used in many safety applications across the industry. Especially in the electrical industry in substations to prevent inadvertent switching of high-voltage circuits or to enter a cage or a restricted area at a plant or a transformer room where multiple keys will have to be used by different key holders in a sequence to allow the lock or breaker or to gain access to some thing or some location. I have seen photos of Kirk key installations requiring no less than 9 to 15 keys don’t ask me I can’t tell you where they are 🤔
Do you try a few different tools/sizes first and then start the video or do you just know what to use when you see a lock
I love key interlocks as well. You really need to feature trying to pick a drop key for an elevator. I understand if you don't want to because, every one of them is the same, but it would be a neat video!
I don't know what exactly it is, but it has a lock cylinder, so I am obligated to pick it open.
This is how we know we are not in a simulation: because IF we really were locked in a game of sorts, LPL would have picked his way out years ago.
This was the nuclear launch authorisation key before they changed it to a keypad code 00000000.
I can't way to see the video you opening the gold reserves door on fortknox😎
Can you find a way of measuring the tension on the lever? like amount of gram pulls ?
It was a Atomic missile lock
I am going to guess that this is a lockout for a machine with two sources of power, the switch shuts off one source and the solenoid ensures the other source is disconnected.
aka a Kirk key device
Our cardboard bailer at Target had a similar design. It was key retaining. And could only be removed when machine was fully stopped.
I think even if a lock like this was pickable eith a comb it would fulfill its purpose. Because it isn't securing something to be stolen but keeping something from turning on accidentally. Interesting lock
On my shed I made a lock system using a regular key type lock. On the back I put a lever on the tab using a key to operate a switch to operate a motor to turn a threaded rod to push a metal rod into the other door. Turn the key the other way and a switch will make the metal rod retract to open the door.
looks like u would use it on a door for a server room as an example. u activate the left side with a badge of sorts and then use the key to open the door or so
Some Adeptus Mechanicus had to build the lock from standard components
Imagine him old and in a care home. With dementia. Picking the lock to the cleaning product cupboard and making drinks for everyone
Maybe it was for launching nukes. It had to get the signal to launch and then the guys in the bunkers had to turn the key. Hey, just as good of an explanation as any.
Can you pick a Car locks Mr. LPL?
This guy can launch nuclear missiles
I’ve seen these on power panels and transfer switch lockout panels
Probably a reversing circuit that the machine needs to be manually reversed
I would have added this clip to the end of this video as a way of explaining what the switch controls... uzload.info/fun/e6SndGbHqm9rrqc/video
It's to stop an operator from turning on a machine while the power is off. For example: Two employees are working on an industrial saw which is on, but unplugged. The one working on the blade is near the switch which they are used to activating in order to use the machine. Another employee plugs in the saw. Bad things happen. This device makes sure that the machine can only be turned on when power is supplied to it.
Sub series.... Picked in seconds.
We used to use pretty much this exact setup at the National Synchrotron Light Source. The key and capture device was part of the safety interlock system. The experimental area, called a hutch, would be searched. The door would be closed and locked and then the key would be transferred to this device where it would be captured. You couldn't remove the key without pushing the button. With the key properly in place, you could open the photon shutter and allow beam into the hutch for the experiment. When the beam was on, you could not remove the key. The key removal button was deactivated. To remove the key, you had to close the shutter and turn off then beam, which would activate the button. The facility was built in the early 80's and was decommissioned in 2014. I wouldn't be surprised if this was actually one of ours that someone saved as a souvenir.
This is called a Kirk key. It’s use is for large electrical circuit breakers. It’s purpose is to prevent two specific circuit being closed at the same time and preventing a explosion in some applications.
This is commonly called a 'Kirk Key'. There is only one key and more than one lock so only one lock can be open at any given time. One use would be a facility that has a generator but no transfer switch. There would be Kirk Keys on the power company main and the generator main. This would prevent the generator from back feeding the power company lines (and creating a very serious hazard for anyone working on the lines). Another one I see a lot is a circuit breaker and a door to the inside of whatever the breaker is powering. You have to have the breaker off in order to open the door.
Looks like a interlock system I saw demoed at an electrical substation. IIRC, it was on a capacitor bank. There was a timer that prevented you from pulling the key out of an assembly similar to this one for a few minutes after disconnecting the main feed. After the timer elapsed, you could retrieve the key from this lock, and use it to unlock the grounding switches. The time delay would allow the capacitors to discharge before the grounding switch would crowbar them, preventing damage to the switches.
Put it in your kid's room as the only way to turn his light on, he has to learn how to pick the lock.
These are referred to as trapped key interlocks. The solenoid enables the removal of a key, which activates a feedback signal to the control system. The removed key is then used to actuate another key switch or lock somewhere else. At no point can both systems be engaged because of the flow of the locks and key, and at no point can the key be moved until the system permits it. So, yknow someone does enter a machine work cell and get turned into minced meat by activation.
Great example about 5:00 into this tour of substation interlocks uzload.info/fun/f39naXKozrFnu4k/video
When he's picking, he reminds me of my dentist. "Nothing on 1, 2, 3, some decay on 4, nothing on 5..."
Because of the complexity and needing to have a signal to rotate the key I'm assuming it's some type of weapons arming system for like maybe launching missiles off a boat or submarine something along that line
and... the ICBM is launched !
Here is your key interlock in action in a power grid substation: uzload.info/fun/f39naXKozrFnu4k/video Its primary purpose is to make technicians think about what they are doing and if/when they fail to think, try and prevent them from doing something life threatening.
Again. The guy that trains criminals. You should be held accountable for any and all criminal acts resulting from your training for felons. Hope you get sued for this. Very irresponsible, this is worst than promoting crime, this is enabling it.
