- In this three-part video (1:10 Dissecting, 5:34 Decoding, 8:28 Reassembling) I take apart a Burg Wächter 4 wheel combination lock (Combi-lock) with false gates (model "88 40 FUN"). I explain how the lock works internally and derive a method to defeat the false gates. Then I quickly decode another lock of the same model with this method. Finally, I reassemble the first lock and explain how changing the code works on these locks. This will give you a great inside-view on how these locks work and how to decode them in general.
Thank you very much for this accurate explanation and step-by-step demonstration. I have now succeeded in picking this padlock model four times in a row. Here are some tips from my experience:
• Start with the two lower wheels. The two upper wheels are usually not binding until at least the lowest wheel’s digit is correct.
• Check after EVERY 2-digit-turn if the hardest-moving wheel has changed.
• While turning a wheel, be careful not to turn an adjacent wheel.
• For determining which wheel is hardest to turn, you have to pull HARD on the shackle.
• The first (top) wheel is usually the last wheel to find the True Gate for.
• You can hear a “click” when you turn a wheel either into the True Gate or a False Gate next to it.
Thank you, accidentaly switched the code, with your Methode i figured it out after an hour
You've just saved my friend 30€! He bought that lock to lock up a machine we'll be getting very soon for our workshop and his 1 year old son messed with the lock in an unsupervised moment. Asked me if I wanted to give it a shot and I enjoy learning new skills like this.
JETZT habe ich das mit den False Gates und wie man den Unterschied fühlt endlich verstanden! Top!
Cool - danke :-)
Very cool! I love seeing how locks work... it helps me visualise the mechanism when I'm picking or decoding :-)
Thank you. Yes, I'm also always very curious to understand how things work and amazed by the little details that can be found.
Thank you for showing this! :D I can now start to see why different types of feedback are produced and how it makes it easier to decode a combination lock. Thank you sir!
Thanks - glad you found it helpful. To take things apart and inspect it closely and feel and play with it make a huge difference in understanding.
Very nice demonstration. That lock is certainly a combination of fun and entertainment!
Yes, great fun with these - I always carry one around in my pocket or on my key chain. Picking without tools ;-)
Very interesting, Thanks for explaining how everything comes together.
Cheers and thanks for watching :-)
Another decoding session ;-) But this time we'll have a look inside... Have fun :-)
Had to decode that exact lock model today in a live situation outside. Your video provided me with all the insight necessary to decode it in about a minute even though the lock was a little stiff after being out there during the seasons. It would have taken MUCH longer if I hadn't seen how the false gates on that lock exactly work and interact with the locking detents. Thanks for that! :D
Nice to read from you :-) and thanks for the feedback to my video. It makes me happy that you could apply knowledge from my video for a real life situation. It's so much easier to accomplish such tasks when you have had a look inside.
Cool. Always nice to see the insides. :)
Yes, very true :-) I'm always curious to see how things work.
I had just unlocked my combi lock thanks for you
Cheers and thanks for the feedback :-)
GREAT DEMONSTRATION. THANKS FOR SHOWING😎😎😎😎😎
Thank you - glad you liked it.
Great video , nice change of pace.
Thank you :-)
Very thorough explanation, thank you!
Thank you :-)
Great vid again my friend. Very interesting explanation about the lock operation and how to defeat it. I really enjoy it Michael, thanks for sharing it to us ;o)))
Cheers!
Thanks - you know that combination locks are one of my weaknesses ;-)
great job buddy very cool info&demo👍😊😊😎😎😎
Thank you mate :-)
Tip Top.. Took me 5 Min to pick a burgwächter... 😂😂😂
very well done my friend!!!☺ nice intro too! time to get combination locks 😊👍 Greetings Julian
Haha, thank you. Cheers, Michael.
Very nice demonstration.
Thank you Pete.
Nice video. Interesting to get a look inside, without taking one apart myself. Thought the new code would be 3142, but that is just me rounding up, because of the 5 behind the 1. The evil curse of math.
Thanks for watching - glad you found it interesting. I was curious myself to exactly understand the different types of feedback and so I had to take one apart for analysis. Quite interesting to see and understand the little details like the step on the tooth. As far as pi goes, I don't wanna have a proper rounded number on my locks but just have as many digits of it as possible, depending on the number of wheels. Imaging having a 4 and 5 wheel lock. With rounding the 4 wheel lock had 3142 and the 5 wheel lock 31416. I find it more aesthetic when the 5-wheel lock just extends the number with the next digit: 31415.
im too clumsy for your method, i also tried using a metal pin to alight the kogs, but there is no room.
then i sat down with my tablelight and observed the first kog until i saw the first metal pin, which was between 9 and 0, which translated to a 7 at the top number, so i only had to try 1000 derivated combinations in theory (7000-7999) and it glady unlocked at 7007 :D
How exactly did you manage to remove the brass cap? I've been trying for an hour now without success ...
I clamped the lock into a vice protected by a rag. Then I used a flat head screwdriver to pry on the cap and a pair or pliers to grab the cup, rotate and lift it up.
Ich versuche es seit 1 Std schon. Ich kriege nicht alle in einer Gate. Was mache ich falsch?
Very clear explanation ! I guess that the Abus 40mm combo lock you carry about at all times for fun is very similar internally ?......(don't dismantle to find out though :o) The press fit cap is a bit less secure than I would have hoped for !! Great to see the innards anyway...
noakeswalker taking the cap off will only allow the shackle to come out, when the right code is entered, so it is not really a big Security flaw
Thank you. I think it's _about_ the same compared to the ABUS - but I find the ABUS easier as the feedback is more clear. Why not taking one apart? - now I'm curious. I might just buy another one for the dissection - in the name of science ;-)
If the cap is taken off while the lock is locked-up, you can see inside and can adjust the first wheel. This makes it effectively a 3 wheel lock.
@Rune International: You're right but you can look inside and easily adjust the first wheel.
Potti314. And then you can put a long needle in, and rotate till all the teeth hit the needle. That is bad !
Taking Abus apart - I just didn't want you to do this on account of me ! But in the name of science sounds like a good excuse to pull that cap off an Abus 40 :o)
I will throw away all my Burgwächter Combi-Lock now. 🤣
I am unable to tell false gates from true gates. Been trying for an hour
Any tips / help from anyone?
Alles seht interessant. Jetzt wo man die Technik versteht, kann man die Falschen von den wahren Toren besser finden. Danke !
i'm completly stuck... my mistake i set a ne code that i don't remember... i have a lock which is exactely the same as your in the video but with 3 rings only... i just cannot do it.... i pull and then cycle the rings but those all turn, without any resistance.
Have a look at this ruclips.net/video/ywR13oj-pnQ/видео.html Hope it helps.
I tried your method and it took me nearly a full day trying and then I gave it up and just before I wanted to go to bed I thought maybe a safety pin thats small enough would fit in those holes at the top and i could find the teeth by pushing and it worked just took me 1 minute and i had all numbers but still good video tho
Sorry to read that it didn't work for you - decoding is fun for me and I enjoy doing it. Hope that you also liked it at least a bit. The safety pin is a cool idea - maybe I try it myself and show it on video or would you like to demonstrate it?
Hello I am not able to delock my combinationlock from burg wächter 90/40
Why are there only 3 false gates ?
Why didn't they do false gates for each number ?
Good question. Maybe just to vary the feedback.
Danke. Nein Kellwtsvhloss hätte sich eben um eine Nr.umgestellt. Dank der Anleitung hab ich es öffnen können. Aber dann kann das auch und anderes :))))
Ja, jeder kann das. Jeder kann auch einen Bolzenschneider nehmen ;-)
Und danke für die positive Rückmeldung :-)
i have a 4 digit padlock with shackle stuck at 90 degrees
Can you decode it open? Pull on the shackle and try to set the code by feeling the resistance on the wheels.
Hm I must do something wrong 3 times I havent found any gate on wheel 4, bottom wheel
Then maybe the other wheels are incorrect.
Kommt dazu noch ein deutsches Video? Ich versteh leider kaum etwas ^^
Die Community is englischsprachig und deswegen sind meine Videos auch Englisch. Das Gleiche werde ich nicht nochmal auf Deutsch machen, aber wenn Du eine spezifische Frage hast, kann ich versuchen sie Dir zu beantworten oder ggf. ein deutschsprachiges Video machen.
Jetzt hab' ich mal ein deutsches Video zum dekodieren gemacht, vielleicht gefällt es Dir ruclips.net/video/rUJXoLPaayE/видео.html
wow that was easy
Dont help me nothing
Sorry
