Master 5422/23D Key Box Decoding
Вставка

- An Oak City Locksport member figured out a way to decode the 5422/23D Key Box. This new decode method was released at CackalackyCon and Layer8. Note that if too much pressure is used that the buttons can break.
Boxes like these are typically on doors for real estate agents, or mounted on buldings for facilities/maintenance teams, FCAP or telco rooms, etc. The problem is that if you can easily decode these, your high security keys or cards are now exposed.

Worked perfectly! You’re the MAN!!! People, listen to the instructions carefully…… the buttons with the most resistance are the ones to crack the code, not those that suppress easily. I learned the hard way !
It worked well. Only took me two tries to get it done. I did not use any tool other than my two hands. I used two index fingers to press the top and bottom buttons down, then used my thumb to feel the feedback / tighten numbers. I located the four tighten buttons quickly. It worked great. Thank you so much! ❤
i did this method and i still dont understand what in looking for. Does feedback mean the the buttons are harder to push down?
Thanks, It took me less than a minute to get it open.
This actually worked, thank you. Took me about 15minutes, but I was able to open the lock.
For those who don't know what "feedback" in this video means, it means the combination keys are firmer, you can't press them down as easy as the non-combination keys.
You are a legend, cheers.
Thank you. I know there's this comment under every lock opening video, but I tried two other, more popular videos first, and this was the only one that actually works. Thank you again, and big ups to that tension wrench guy!
Ty!!! Did the trick. Helped me to reaffirm the correct code. It wouldn't open because one of the button mechanisms we turned on was malfunctioning out of the box. After struggling a bit, we got it open and turned the malfunctioning one to off. New code works great. A bit unnerving how easy it was to decode with this method. 😮 Will have to reassess our locking protocol.
I used the tension wrench like his 3/8” made one. Then make sure your on a flat solid surface, then I laid an 8mm 5” long Allen wrench on top of the activation button he’s jostling if you notice when he pushes down it wants to move up slightly on its own. If you use the Allen to just prevent that from free raising then just press the button with little force you will visually see the button ever so slightly move ant that indicates a lock code number. Reposition your Allen to hold the position button slightly so it doesn’t lift on its own and repeat. Record the numbers that you see cause a very slight visual movement of that top button. You will notice buttons won’t move it they are ones you won’t use.
the lockbox I'm working on is hanging on a door knob and impossible to lay flat, any suggestions ?
Sweet! This method worked for me. It worked really well, I opened it within 15 seconds after I put the tension wrench in place. Also, I hit the Like button and I also Subscribed. Well done!
Boom! Worked like a charm.
Thanks for the helpful info.
Ok. This was perfect. After hearing the method, I was able to find out the combo on this lock before the video even finished. Now I don't need to go buy a new one. Probably should with how easy that was, but it's for work. Not my problem.
Thank you!! Your method worked!!
Get Patrick I just wanted to let you know I tried your method last night, and it worked. It wasn't easy and I needed 3 hands and a thin knife to let it open but going through your steps definitely made it possible. Thanks for your channel.
Thank You so much for the help!!!!! It worked great!!
You're welcome!
It worked! Thank you so much for the info.
I worked! Thanks!
You just saved me an entire day of labor. Thanks man.
You need to DEFINE and/or EXPLAIN what the FEELING of said "FEEDBACK" the correct #'s in the combo give, that the INcorrect #'s do NOT give...
Basically; the correct and incorrect numbers are both going to give you some measurement of "feedback"...
The easy way is to drive the hinge pins out with a pin punch and hammer. With the pins removed the cover falls off and you are done. Now you can read or reset the code and replace the pins.
I Love you. Thanks!
Took me an hour plus but I got it thanks!
I've tried for over 30 min. and still can't open it.
Thank you save me from buying another box got it open in 45 minutes
I tried this method with a wall mounted one. I'm having difficulty. Decoding it. Any tips?
WOOOOOOW, That worked!!! My lock is 5422 model P19919 that I bought a couple of weeks ago and a kind of joker found funny to lock it and did not leave the combination.
I put the tip of my finger in water to make sure it is sensible enough and tested for every button. I used the tool lock in the Clear button, then moved the lock/release button up down gently with the finger on it.
Then I felt buttons that does not transmit movement at all, some that transmit the vibration and some that transmit the vibration and movement enough strong like if there is something behind communicating the movement. I compared the button of most sensitivity with the rest of suspects to discard. I get a three digit combination and voilá, opened.
Thank you Oak City Locksport!
Great! Glad to hear that!
Thank you so much!!!! This worked like a charm!!! It took me a bit to understand the mechanism and reading the others comments worked for me!!
My lock is vertically mounted.
I used an Alan wrench to push down the bottom button all the way down (without putting any pressure on the top button) and tested each button, saw the top button slightly vibrate when pressing slightly repeatedly on the buttons with the most resistance. Figured out the 4 combo and it worked!!
I picked this model without the new technique you were using. I tried that way but it locked up the buttons and I couldn't get any feedback. I went back to the LPL method and while at first it was hard to tell which buttons were free under spring tension, it eventually became clear that the non-combination buttons would bind after bottoming out with a sort of spongy feel followed by some friction on the last 20-30 thousandths of an inch or so. It was a bit of a challenge getting the feel for it but now I figure I could to this again on demand in a few minutes. The weird thing was that if you follow LPL's method, you can work your way down to the final row, #,0,*, and if you've pushed in the wrong buttons on the way you won't get correct feedback and it will be hard to tell if that row has any of the combination buttons. In that case try starting from the bottom after resetting the buttons, pushing #,0,* and then the release lever while testing each button for binding. Usually you can get a better feel starting fresh.
Aa
Can you explain the LPL method?
Thank you
LPL means the video solution provided by the lock picking lawyer LPL. He has a different technique
Are there any key lock boxes that you would recommend or at least rate much higher than this for securing keys?
Man I have a problem,, for some reason all my numbers seem stuck, I take the key inside got loose and it's jammed. I'm going to try this method. Thanks
Awesome
Hello, I have tried this and I have an anti-jamming one. I can't get in it at all. Can you please assist me this is so frustrating and unsure of why?
How do you open when you sscrew up the code
What if i have a 5 digit code? And where are we supposed to feel the feeback? On the down arrow button or on the actual number buttons?
It is actually the buttons not going down are the ones with code.
I can't do it. I have the exact one that was left from a contractor years ago. I forgot the combo. i tried this and it wont work. All the buttons feel the same.
0:46 You are doing it incorrectly. Start by clearing it, then pressing the 1st three buttons on the top row, then put your pressure on the lever, then press each of the 3 bottoms in the top row again and if any have free range of motion that is one of the codes. Do that for each row.
Best of others
Everywrites it is working is it only me or my lock is not responding as is?😢
OMFG lol I just did it with the same fucking LOCK BOX LMFAOOOOO HOLY SHITTTT THIS VIDEO WORKS HAHAHAHAH BOOYAAAAA BITCHES!!!! THANKS OAK CITY LOCKSPORT !!! Saved me 35 bucks
What about if I don't have the combination, my son totally forgot
Property owner used house address number to open the safe. Fifteen second solution.
Feedback? English please for us not so smart people. Thank you
I just bought this lock (5422D). Thought I had my combination in, and locked it up. Well, guess what! Apparently I didn't do something right and I can't get it open. So, this will be a 50 dollar lost if I can't get it open. This is for the EMT's to get to me at case of an emergency. So, hopefully this will work. Still trying though, because I do not want to spend more money.
And the reset button being forced down made all the numbers hard to push down. Didn't work.
Yeah I'm trying it right now on this model and I can't get any feedback at all with the reset button held down. It locks the buttons just like you said.
😊
The combo can be up to 12 numbers. So maybe it's all of them?
Every button but 1 and 3 have movement but I can’t crack it? Please help
I work for a repair company and our installers forgot the code so we can’t reuse the box until we figure it out
@@tarahull7243 Did you ever get it?
that is absolutely ridiculous didn't even need the tension wrench just held tension on both at the same time. got in mine within 5 mins. any stiff buttons are part of the combo.
Doesn't seem to work. For comparison, I tried it on a lockbox that I did know the code and it also didn't work
This video worked like a charm! Very slight movement, but worked exactly as described!
Are you looking for binding or free movement in the combination keys? In the LockpickingLawyer video with a similar lock he is looking for free motion without binding to indicate the combination buttons. Is it the reverse here?
I can't get either this method or LPL's method to work for me. What gives?
Not sure... but I've seen neither work when one or more button has seen some wear and abuse...
@@OakCityLocksportyeah every damned one of these frickin numbers are loose and I'm about to get a bloody hammer!
Mine worked by identifying the numbers that were hard not soft. Why have this lock anyway if it is so easy to break into?
Amazing video! Although your method did not work for me, it did bring me to the right track- I am a locksmith in Maryland and had a customer bring me on of these. For those that want to try a different way: Use the original jamming method for the anti jamming model. I was using a P19918 however, you will get keys that you press down that feel SOLID and give little to nothing in return. The other keys will give slightly or may even click- its a very tiny difference in the amount of distance the keys press but the solid keys ARE noticeable!
So are the solid buttons the combination? In the LockpickingLawyer video with a similar model you are looking for buttons that move without binding while pushing down on the release bar.
What should I be looking for as far as "feedback"? This video is frustratingly vague and feels more like trolling.
Fr lmao
I believe that this method was working for the lock I had given to me as part of a tool lot but it still wouldn’t open. My model was the wall mount version so I finally just drilled into the back in the top and bottom and could see that the buttons I had guessed were activated were the right ones. I was able to turn them around get it open to discover I have 4 buttons that will not function. What crappy locks. Oh well. I was fine drilling the holes in this one since it’s getting mounted with screws but good luck to anyone having a functional one for long that hangs on knobs
This did not work on my model. Once the reset is pressed and held, the upper lock release locks in place and does not move. Any other methods for entry?
Get small pin punch and drive the hinge pins out. The cover falls off and you can reset or read the code. Drive the pins back in and you are good to go.
I have a square lock box. 3 number combination. We used the combination we had. Will not open. How to get a new combination.
You set the combination from behind the keypad. So in other words. You are screwed. You have to get the box open to create a new combination.
TRADUIR EN FRANCAIS SVP
Dev sent me.
LPL did this one a week ago.
Ok. Check the date on my video. Literally talked to LPL in person about this today ;)
LPL's method may be easier, but both mine and his require a certain level of sensitivity to the feedback on buttons that may not work reliably for people new to button decoding.
Why? I'm looking for security for my senior mom with home care and med alert. And looking for a secure key locker. And now anyone can just open them up? Have you offered any alternatives that can't be so easily opened? First time viewer.
Hope your mom is OK Dave. Nothing is foolproof, nor can withstand a dedicated brute force attack unfortunately. That said, the one key box that myself and others have found that can't be decoded is the Kidde Accesspoint with a dial combo that I recommend in the comments below.

I am in the exact same situation and I was borderline pissed off to see someone happily offering to teach thieves how to defeat it. Seems pretty unethical to me
Damn. Didn't work.
Sorry to hear that! It worked for several members of Oak City Locksport and participants at the Layer8 Lockpick Village. What I'm learning however is that there may have been a design change at some point. In some cases the buttons will jam up more than others. Best I can tell this technique works on newer models of this lock.
@@OakCityLocksport I purchased mine about 2 years ago. and can't open it.
:-(
@@LillDragun I would suggest trying the original method of holding down the latch release lever at top. Then push on the buttons and see which ones are harder to push down. Those are the ones that are likely in the combo. Does yours say "Anti Jamming" on it like the one shown?
Didn't work for me either
@@OakCityLocksport mine says anti jamming, doesn't work, I can't feel the difference between the buttons
As the potential purchaser of one of these boxes (not for real estate use), may I ask: what kind of person would post videos such as this? It's a genuine question btw. Is it to help the manufacturer (in which case you would surely contact them directly and discretely), or is it to basically assist various unknown scumbags with their criminal activities? If the answer is that it's to assist genuine locksmiths, then surely they should know this stuff already or they shouldn't really be in the game?
That's a question that all locksport communities are asked on a regular basis. It's to protect YOU. If you were going to be using a banking or email site, wouldn't you want to know if it had critical vulnerabilities that would allow someone to steal your money or your private information? I bet you would. The point here is to educate consumers on the relative security or insecurity of the locks you rely on. If you see it here or on other channels like Lockpicking Lawyer or Deviant Ollam then chances are you won't buy it. If you're in the market for a consumer box I recommend the Kidde AccessPoint 001012 key box with the combo dial on it. I do not work for or represent them, but the seem to have the best solution at this point.
@@OakCityLocksport Thanks for the considered reply. It was a bit of a rash post which I should probably just delete; I apologise if it came across as rude. I've just realised that there's a kind-of community of what I would call 'lock enthusiasts', which I didn't know existed. If that's their/ your thing as a hobby, then fine. My worry is that experts such as locksmiths and the aforementioned enthusiasts can break into any product, so if I were to start researching it, I bet virtually all reasonably affordable locks and safes are vulnerable. And by affordable I mean that I'm personally prepared to pay more for quality, but obviously I couldn't stretch to paying £1000 for a safe just for home use for instance.
Do you guys ever posts when you *can't* break into a product? I was thinking about getting myself a Squire SS65CS Stronghold Moto with Mauer A440 R1 core at some point in the future, thinking it to be one of the strongest locks on the market, but I can almost guess what's going to happen if I research it now! BTW, it would be quite helpful if channels such as yours could recommend alternative products, although I recognise that if you were to actually do that, it may be that only a few products would be on your list for ages, meaning you're doing the relevant company's marketing for them, for free.
@@soots-stayingoutofthespotl5495 Not to worry, we get that question all the time. It was actually a great setup. If you are OK with leaving it I am as well.
Your not seeing the bigger picture, they show you what's something to use, obviously not garbage like this
REALLY ?? DAMM ,, THEN IT SEEMS USELESS 🤷🏻♂️🤷🏻♂️🤷🏻♂️ ITS LIKE LEAVING THE DOOR 🚪 UNLOCKED 🤷🏻♂️🤷🏻♂️🤷🏻♂️ ,,, SUCKS !! TNXS FOR THE INFO ,, I WILL AVOID TO PURCHASE IT ,, 😂😂
Doesn’t work!
This doesn't work anymore, don't try it.
thank you I opened it easy the real state refused to take the lock after I bought the house try those Botton the one resist and feel hard
Your method doesn’t work sorry to tell your followers.
It for sure works, amigo. I don’t know whose channel this is, but it worked once I realized what I was looking for.
I’m lost... will someone tell me WHY anyone would post instructions on how to defeat a form of security ? As I see it, those who post these how-to videos only serve to educate thieves, but I’ll try and give you the benefit of the doubt and assume (for now) that you do have an ethical foundation - at least for now.
Darryl, thanks for giving me the benefit of the doubt, and please be assured that I have the best intentions and ethics in mind. Your reaction is pretty common for those who get exposed to lock picking and lock decoding for the first time, so please allow me to explain. First off, thieves are more likely to just smash a window or bust in a door than use a technique like this. They don't care about non-destructive entry. Second, there is a large "locksport" community that does this (that we're a part of). Besides having fun with what is essentially a "puzzle", our goal is to educate consumers on the relative security *or lack thereof* of the locking products they rely on every day. We'd rather you as a consumer know that something has issues than expose yourself to additional risk. Believe me, a thief who IS interested in non-destructive entry already knows this stuff. Also, if it finally shames the manufacturers into fixing their products one day we might have done some additional good. Think of the locksport community like the Consumer Reports folks who find things that are unreliable or don't work as intended.
To look at this yet another way - my "day job" is working in the Application Security industry, helping fortune 100 companies find security holes in their websites and mobile applications. Applications today are not all built "from scratch". They use a combination of custom written code and common components called "libraries" that are like building blocks. These libraries are "open source", meaning a team of volunteers has build them to do a specific function. Developers use them so they can build and app quickly without having to re-invent the wheel. Occasionally those folks publishing a library make a mistake, resulting in a security bug. If someone finds that bug hopefully they report it to the library creators, but in many cases the library creators don't do anything about it, or they're not around anymore. Reporting the issue publicly to the National Vulnerability Database is important then so that everyone knows about it and can update their code. If it wasn't published then criminals could find and exploit those holes not just in one company but in hundreds or thousands of them! Publishing vulnerabilities keeps everyone safe.
Most thieves will just break your window or door, so in the end it doesn't even matter, so get off your high horse. Seriously, it takes 2 seconds to break your sidelight and reach through and I guarantee that 99% of the time the neighbors won't even notice, let alone look into it.
As I always say: "Locks are for honest thieves".
In my situation, a lock box was put on a property and the code was forgotten. Simple as that. Need to get in to take photos and put on the market.
Here’s some advice your videos are like a low quality version of Lockpickinglawyers you should watch a lot of his videos and break down what he does and why. And then you need to figure out how you can do your videos in a more original way and or in a better way. It’s a simple as that.
Or you can just go away. LPL doesn't own the whole of the UA-cam and no one is forcing you to watch.
