(picking 206) Master 4-wheel combination padlock opened - fuzzy decoding method - thanks to Ulrik 

It works! I found this lock years ago on the street, was laying in my desk drawer and just picked it with your method! Thanks

Thanks! I've got this lock with letters instead of numbers. I've had it for years and occasionally pick it up to try and solve it. Thanks to this video I finally did it!

After months, I know I could have bought a new one but was not happy to just throw away. I watched this video, within10mins I had it open. Brilliant.

Wow I am impressed I have never tried opening a lock in my life I listened to your video and in less than 5 minutes I opened the lock that I got in a auction job lot . Thank you for the great video . Im still smiling

Thank you for the fantastic video. I have 4 of these locks and apparently when I set one one of the codes were way off from the other 3 locks. I was about to throw it away until I just discovered this video. You saved me!

OMG this is soooo amazing!!! thank you, just less than a minute I was able to get the combination!!!! Thank you! great tutorial!!!

Brilliant video. Missus accidentally changed the combination. Possibly might not get rid of her now thanks to this. Thanks. 👍👍

Thank you for this video! I accidentally reset my gym padlock last night somehow, same model as this, and this has helped me work out the new combination. On the other hand it shows how easy digital locks are to pick😬

Brilliant explanation. The locks I have contain 3 false gates and 1 true gate per wheel. I have now decoded them both. Need more locks now. Thanks Mr Potti.

u’re fab! i was in the same position as others, with a padlock that i didn’t want to throw away... although i was 100% sure of the combination, it just didn’t work. it was either reset by someone else or the problem came from that it wasn’t locked back in the proper position 🤔 anyway i watched many other vids that didn’t help, but this one did, thank you, u’re a legend and i now have a padlock that’s working again 😊 thank you

Thanks for your video. I just got open 4 locks we did not know the combination for. The best part is that all 4 were the same combination.

I have the same lock but it's only a three wheel combo. I found it very easy to find the gates by pulling the shackle and starting with the first wheel and it pops in the gate and to me it's very noticeable But with that said you taught me something. The lock was given to me by someone at my work and I did not know you could change the combo so thank you for that. Now I can play with it some more :)

Great video! I'd been struggling with this exact lock for a while. Had it open in a couple of minutes after watching this! Thanks so much! 👍🏼🙂

Nice and clear instructions, managed to unlock my old Master lock without having to throw it away. Thank you

omg .. I almost thought to get rid of this padlock but thought let's try youtube and within a few mins I was able to open the lock. Great help .. thank you :)

I have been trying to find a method that works on this lock for two days. Then, I got the lock open in 10seconds with your method. Wow. Thanks mate.

Thanks, I've had this lock locked 4 years but refused to throw it away, your video just helped me unlock it! 🔓

hehe: I had a lock and chain from a friend who forgot his number, with the tips I opened it in less than 5 minutes! thanks! GOOD JOB!

Brilliant job, I've just get the combination for my pad lock as follows your method, Thanks

HERE'S THE INFORMATION YOU WANTED ON THIS LOCK. Thumbs up great video. I pick and decode locks for fun. I'm always looking for a challenge. DIRECTLY BECAUSE OF YOU I BOUGHT THIS EXACT SAME MASTER LOCK, as featured in your video. I agree it's different, I picked it EXACTLY as you had described. But if you take another look there are a number of other methods that still work such as finding the loosest wheels, not at all difficult. And contrary to your video it does have false Gates, but it's so poorly made,!!! They are there but are rather shallow and ineffective, and simply tensioning the shackle will bring you right to the correct number. It also has features that no other lock has such as that the numbers lock when the shackle is open and easy to use and to operate the CHANGE CODE POSITION. It's so poorly made by MASTER LOCK that all of its weaknesses can be exploited easily and therefore there is no reason to tear it apart. It's one of my favorites to play with. Thanks for listening and for inspiring me to buy this lock. Take care.

Thank you , . I learned something new today........👍😄 got it 1st time watching & within in 5 mins in your video I was able to open "Model No. 630D" . A brand new lock my other half had purchased a month ago and locked it unaware of # code. Thanks to your very well said video he finally can set it right and use it.......

Great video, helped me to open a 4 digit padlock in more or less 30 min. Thanks a lot!

OMG you are a legend. I had a "Master" brand lock and this was the only video that helped. YAY!! Thank you!!!!!!!!1

amazing. i tried to open this lock for ages and used a few different strategies without success. with your method i had it open in 2 minutes.

This method also works on the Master Model No. 643DWD which has letters instead of numbers. Can now unlock it in anywhere from 30 seconds to 3 minutes. It works best if you attach a rubber band to it, and then anchor it to your knee if you're sitting down. This gives you consistent pressure, which makes it a lot quicker to decode. Note: dont even waste your time on the top 2 wheels. you almost have to treat the top 2 and the bottom 2 wheels as a different sets of tumblers. Step 1. Apply a lot of pressure to the padlock. press down on the 3rd wheel so it can't move anywhere, then rotate the 4th (bottom) wheel until you get 2 letters/digits that the wheel moves loosely on. If you can't quite find any that are loose, apply more pressure. If you still can't find any, mix up all the combination wheels and repeat step 1. Sometimes if the top 2 wheels aren't in the right spot, you can get false positives. When you find the 2 letters/digits that move loosely, you'll know. just select one of the two and move on. Step 2. Apply pressure to the 4th wheel now so it can't move. Now again apply pressure to the padlock and rotate the 3rd wheel. This wheel requires a lot of pressure on the padlock. You are again looking for 2 digits/letters that the wheel moves freely between. Select one of the two digits. If you get false positives on this one, or they all have about the same feel, you'll want to mix up the top 2 wheels, and repeat step 2 again. Step 3. Now hold down on the 1st wheel, so it can't move... a lot of times this wheel likes to move around, especially if the bottom 2 wheels are correct. Apply pressure to the padlock, and move the 2nd wheel, sometimes you'll know this one right away, as it may click into place and the padlock may give a little. i've also had it where it was between another set of 2 combinations as well. step 4. Apply pressure to the 2nd wheel so it cant move, This one also likes to move around with the first wheel. Apply pressure to the padlock again, and rotate the 1st wheel, if all goes well, it should pop open. If it didn't open, try shifting one of the bottom wheels over to the other position that was loose. If all else, repeat step 1 and 2. if you still can't get it, just mix up all the combinations and try it again... when you finally start to feel the "loose" areas, you'll know you're on the right track, and it gets easier. i was so confident with this method, i mixed up the combinations several times without looking and decoded it pretty quickly. it requires a lot of consistent pressure on the padlock, why I dont recommend using your finger, because you have to keep getting a better grip, and you might not feel where the wheel goes free.

Great tutorial as usual. I've always problems with those combination locks. I am not persistent enough ;-)

Thank you for the video! I manage to unlock my for less than a minute 😊

Thank you! Unlocked my old gym lock

i have that exact same lock and i just managed to unlock it thanks to this video! many thanks!

The lock (Master with 4 letters) on our shed in which I keep my telescope and accessories would not open, we tried for weeks! Same combo we always use so should have easily opened, but no luck. We sprayed with graphite to see if that was the problem, which helped the tumblers(?) move a bit more easily but still no luck. I googled "how to unlock combination lock" and your video came up, I watched it, and within 20 minutes had it open! (BTW found two letters of the combo had been changed up accidentally - maybe pushed up on lock when opening/closing who knows?) Thank you so much for posting this! Also, read your recommendations for more secure locks and will be getting one of those! :-)

Thank you! I have the same lock and this worked for me. Cheers!!

Its work ! I unlocked my lock in 2 minutes after watching your video!

Nicely done mate !

I got movement on the shackle on all 4 wheels just a little on the first 2 and enough to get the lock to spin open on the 3rd but not enough to reset and the 4th was just try one till it popped thank you I'm very pleased to have learned a new a new skill

I just also opened mine with extrem shackle pressure - so I found the correct gates very fast!

Cheers mate, really helpful video. Was able to get it in a about 10 minutes

I did it but not how you did… basically I just started from the top and found the number what didn’t turn under pressure then moved down to the next worked pretty must first time!! Thankyou!!!

I have the same silver 4 digit lock. It was giving me a really hard time today. Wasn't opening the shackle at all. I will try again with this method tomorrow. Hopefully it works.

After trying for a while it worked, thank you very much

I forgot my combination 👏👏👏👏👏 thank you bravo

Yaaaaaah done it ...massive thanx to your tutorial

I got mine open while watching this. A real easy way to pick this lock is to pull on the shackle try moving the second one down from the shackle...If it moves freely, move the tumbler closest to the shackle to the next number, and try moving the second tumbler again. Keep doing this till the second tumbler gets hard to move. You just figured out the top number. Now go to the third from the shackle and try moving it until it gets hard to move, you will be figuring out the second tumbler. Repeat until you have them all done. I think I could easily pick this lock in well under a minute. Kinda sad, but fun. Take care.

I've found an alternative way to decode these, or at least the 643D I just got. Turn each wheel to the position where it wiggles most freely. Do not use any shackle pressure. The detent is solid on every position of the wheel, but the axle the wheel turns around feels loose when it's oriented correctly. The wheel wiggles back and forth in the body of the lock, pivoting around the detent (left of the wheel). I've decoded it a few times now after having blindly set an unknown combination on it. I have no idea if this still works on locks that have more wear on them, as I opened the package on mine just a few hours ago.

Let’s go, just cracked my first lock! The numbers were 1749 - however it a little different to crack as it was already open and not locked!

Thank u, it really works 👍🏻👍🏻👍🏻

Not working… i have even cheaper 5$ ABUS 3 digit lock and 6 years im trying to open it and its not opening at all. When i pull up the shackle the first the first disc moves heavy on all numbers and second less heavy but still heavy and last disc is loosely spinning and i get no click on any of the discs at all… I want to open and use it not to break it. So what to do?

My lock shackle was locked outside and number was moved so now I cannot bring the shackle round into position to get number decoded thanks for anyhelp as I have 3 the same position

Thank You!!

My Abus 165/40 doesn't give me as much trouble as this one does. Has anyone seen a video of this being taken apart yet?

Thank you, I was about to throw my lock away. It was locked and had forgotten the combination. Using your method, I opened in about 2 mints! You are awesome!!!

Super! I have to try it with my locks

It works! Thank you great job 👏

thanx worked .....loved your video though .....this one really helped me ....thank again

Thanks. It worked for me.👍🏻

thank you sooo much i am in a shared accomodation but the ladlord is strict and put locks on the boiler and electric meter boilers gone down and needed the code thanks to this video im in cheers potti314

Hi Can anyone tell me how to close or reset a 4 combination Master lock that I have forgotten the number to. It is in the open position and will not lock. How can I reset it without knowing the current 4 digit code. Anyone?

Great video problem sorted 😊

Thank Bro that helped me a lot

i have a similar lock it was in my bucket of locks i to was having real trouble unlocking it i was just not getting any feedback and the wheels apart from 1 seem to move freely all the time. that was of some help to me though i think its going to challenge me as its my first combination lock and as you no im a neewbie. great vid and thankyou

I have this same lock only it's letters and I lent it for my sister to use at the gym and now the bottom spinner thing is stuck and won't turn to open it. I already know what the combination is because it's mine. I don't have my packing and instruction since it's a lock I got a while back. Help. I can't spin it to fix it. It's already opened the lock but just stuck and unusable now.

Really cool, I've not managed to open this one :D

Please how to set to open lock ? I have an open lock but I do not know a code. thank you

thanks, it worked perfectly!

And if a lock is opened but I dont remember the code. How do I reset it to use it again ?

Many thanks for this video very helpful 👌👌👌😀

How do you choose which side between the two stops to use? Try both?

Thank you bro. We were locked out of the medication fridge at work and we were able to open it because of this video. We dont know who changed the code tho. It must have been the devil because it was 7666

At the 3 minuet mark if anyone skipped to that they may think you were up to something rather rude 😳😛😉😂😂😂😯😊 I have had one of those I had to get open and the way you have shown was the way I overcame the lock🔓👍👍👍🤔 I even tried to feel for a gate down the side of the wheels but couldn't manage that either😞 Thanks for sharing 😘😘👍

I have this same lock, however the shackle is stuck in the 90 degree position that you use to reset the combination. It turned like this in my gym bag and changed the combination on its own. Should the same tricks in this video work when the shackle is in that position? Been trying for 20 minutes with no luck.

GREAT VIDEO BY THE WAY

Hi mate. My ABUS 165/40 was nowhere near as easy as yours to decode. Had been locked on a shed for 9-10 yrs and never used. Took a while to open so brought home and dropped it in a friends sonic tank for a few hours and rinsed it out with WD40. Now works a treat. Still find it hard to get a shim aside the wheels tho'. Good locks.

I have a similar lock which is open but I can’t close it, as I have forgotten code, the wheels all spin easily no tension. Can you help please.

after trying mine for 5 minutes it's unlocked thanks

Have this exact same lock and I was trying this method and was able to pop it open one minute before the video ended. Talk about interactive.

Just saved me a lock. Thanks

I just managed to do this with a Cocraft 400BC which is probably a rebranded Master lock. However I can't change the code on mine. Thank you!

always enjoy your combo vids mate, and every time i swear i'm gonna give it a try but never get round to it.....one day! but at least i can refer to your vids as a tutorial as you really have covered a wide variety of combo locks, it's very impressive! cheers Mr Potti!

I have that lock but I it is open and I Lost the combo so I can't close it and you can't change the combo with it on the wrong combo I tried this and it won't work any suggestions?

Thanks I unlocked my grandpas liquor cabinet whisky time!

Thank you sir!

Thank you Potti314 for another fantastic video - you have really clear lock picking videos, and a friendly voice! You have inspired me to learn lock picking & also to start my own lock-picking youtube channel.

I have a master lock. I think it is slightly different to yours and I have been trying for 3 hours and 4 different methods and still can't open it. Anyone know a different way?

It looks like once it's decoded, the wheels may be set to "half" positions (not right on the number where it crosses the line on the front). Am I seeing that correctly? I am working on a lock that has been locked without the shackle being seated in the groove (so off to the side of the body of the lock).

@potti314 - I have this lock and the combination was changed while the lock was open. I cannot close the lock to attempt to decode it. Is there a method to obtain the code while the lock is in an open state? Thanks in advance.

Aaaaaaaaaand just as you finished your video, I got mine to open.

I have a four digit combination lock that is in the unlocked position and I can't lock it as I have forgotten the code. How do I find out the lock code this way around?

Thank you so much🙏

I have this lock but it's stuck open. How would you suggest to hack it

wow. impressed... this really worked. thanks a lot.

Thank you so much ... 🙏

Brilliant I cracked it.....BUT...I can't remember it now to close it...do I just reverse what I did..as been trying for 30 mins now

I've got a lock exact like this but the problem is the lock is already open and I forgot the passcode is there any way to open it?

Potti - I believe each wheel has at least a false gate (mine seems to) and all I do is pull on the shackle and rotate wheel 1 to 4 watching for and feeling for shackle bounce. The shackle moves very positive when you slot in a gate (false or otherwise)

Lock picking is like knife collecting, just cuz you like knives, doesn't mean you like going around stabbing people. But its nice knowing you have that ability when you need it. XD

How do you figure out the code if the lock is already open but you forgot the code?

holy shit i acctually got it i created a wrong kode by accident and now its open though i had a general idea of the first 2 digets i had no idea where it went wrong THX

hi there. i have a 4 wheel lock. i got it from Pure Gym a couple of years ago here in the UK. im really struggling to pick it. could you help me plz? Richard.

Damn! I have this lock, just bought it. I messed up with setting the initial (own) code. I watched this video, and opened it before the video ended. Lol.

You're a life saver

I have the same lock, but somehow, someone has managed to lock the shackle down outside of the body of the lock, so it hits the side of the lock when rotated & won't go over the hole. I don't know how this happened. Putting in the last know combination won't release the shackle. Any ideas?
