(Picking 120) How to open a MasterLock 175D if you've lost your combination

Here I show how to bypass & open the new & improved MasterLock "175D" if you've forgotten your combination. It's much more secure than the old "175". I also show a method to decode it to find the actual combination.
This method is based on Potti314's video for the MasterLock 178: • (picking 481) Master 1...
Note that to decode the lock, it's basically doing the same as this: • (1517) WordLock Store-...
... except it's more difficult and you have to manually pull in & out (and it's a pain because of the tight fit).

Thanks John for sending that so Swynndla could decode it for us all, that's the first Master I've seen that's hard to open. Great video my friend.

[@Swynndla]

I know, I can't believe I would be happy to use a MasterLock! ... it's great they are starting to listen to the locksport community! Thank you 3dog :D :D

[@PocketWomen]

Excellent decoding and explaining what was going on. thank you for this video, cheers

[@Swynndla]

Thank you for the kind words PW! :D :D

[@cherokee8647]

Super job on this MasterLock 175D. Great video all the way around. 👍👍👍👍🧡

[@Swynndla]

Thank you Cherokee! :D :D

[@noahway13]

I like your channel and thanks for giving credit to Potti. Most people on here steal info and try to play it off as their own. Especially the biggest name in lock picking right now.

[@Swynndla]

Thank you for your support ... I'm glad you like my channel - cheers :D :D

[@dazevers]

As always my friend a great job. Although that master lock was a quite resilient. Have a great weekend.

[@Swynndla]

Thank you mate! Have a good one :D :D

[@tipenengapuhi]

I was given a MasterLock 178 without the combination. I used exactly the same shim on the right hand side of each wheel technique. Like you say, if the shim inserts horizontally you have the correct number for that wheel. Once I had them all, the lock opened without the usual rotating the wheels in unison and testing the shackle technique.

[@Swynndla]

Nice! You did very well! I had seen Potti's video before, but I had to watch it again before I could figure it out. :D :D

[@NowhereBaby]

Thanks for this video! I recently got a new Master Lock 175 and I was able to bypass it thanks to your demonstration. Thank you!

[@Swynndla]

Well done! :D :D I'm glad it helped.

[@jackfoxlock]

Thank you :D:D for a great video. It looked like a lot of work for a lock that was trashed for years because of the quick bypass. Master Lock has made the 175D a lot harder to open. You and Potti found the weakness. Now l don’t fell so bad about not being able to open it. I am going to work on my 175 D first thing tomorrow. Thanks again for your help.

[@Swynndla]

Hehe nice - i hope it helps. :D :D Good luck my friend. It would help to use that deciding tool, unless you are able to make your own (but that would be hard as it'd need to be very thin but strong). Thanks once again for the lock - lots of fun!

[@jackfoxlock]

Swynndla Just opened the 175D using the two methods in your video. They worked like a charm. I did find that for using the left side to bypass, it is helpful to put a very slight right angle bend in the very tip of the bypass tool to the right to get it behind the wheel. This lock was Avery hard nut to crack. I have no qualms in using this lock to secure a locker or shed or gate.

[@Swynndla]

@@jackfoxlock That's fantastic! Well done! That's interesting ... my decoding tool is slightly bent - dunno if it helped me - i should test. Yes that lock would be more than fine on a locker (even though it's a MasterLock! - well done MasterLock!) Well done once again! :D :D

[@SasPes]

Another awesome video, well done 😉 Bravo 🍻

[@Swynndla]

Cheers mate! :D :D

[@harrystevens7140]

I used the technic that you said might work by using the tool to go in straight to find the correct numbers and got one open brovo for the demonstration

[@Swynndla]

Fantastic! :D :D

[@ajclark9939]

Thanks for sharing this with everyone it is very informative and helpful.

[@Swynndla]

Thanks mate I'm glad you liked it! :D :D

[@crankylock7844]

Good tutorial on the Master Swynndla. Until the next one. Cheers:-)

[@Swynndla]

Thank you Paul! :D This one isn't too bad. :D

[@RASAllusion]

Great Video!

[@Swynndla]

Thank you! :D :D

[@arielban1]

Was going to buy this, but now changed my mind. Is there a combination lock that is much harder to open? I need one for my home. Thank you in advanced.

[@Swynndla]

There are some good combination locks but they are expensive (like the ABUS 190CS/60). If you want something cheaper, then get a key-lock instead of a combination one ... make sure it's a good brand like Abus, Yale or even Masterlock would be ok - even though if someone knows how to pick key-tumbler locks then they will be able to get into a Masterlock fairly easily, but at least Masterlock's have strong shackles for bolt-cutters etc (and that's how locks are mostly attacked, with bolt-cutters, hacksaws etc) so they'd probably be fine. If you really want a combination lock and don't want to pay that much, then the lock in this video: "MasterLock 175D" (make sure it has the "D") is "okay" because someone would need to know what they are doing with a specialized tool (and again a real thief would use probably use bolt-cutters), or even better get a dial-combination one like an "Abus 78KC/50" (see my video 87) but *not* a Masterlock one in this case. The general rule of you get what you pay for is certainly true for locks, and it's generally worth spending more to protect your stuff. All the cheap unknown brand locks say "high security" but it's all lies. Trust known brands with good reputations. Well, that's what I think! :D

[@eleodoropena384]

I open mines already now im trying to reset the combination..with the key ..but is not letting me ..is their a way to reset it

LOL my Kiwi accent? - cheers! :D :D

[@tubagusrusmana3246]

Where i get the lockpicking?

[@LockpickingsGal]

Great job decoding and opening!! Have you ever tried a sesamee combination lock? I got one given to me at a garage sale. I don’t know the model number but it is in black.

[@Swynndla]

Thank you LPG! I've heard good things about a sesamee combo's and I'm going to splash out and buy one of these & ship it to New Zealand: www.amazon.com/gp/product/B004FF3ABM ... they are meant to be really difficult to decode (maybe impossible I don't know).

[@LockpickingsGal]

Swynndla that’s not the same one that I have but I’m sure that you can figure this one out!!

[@Swynndla]

@@LockpickingsGal hehe thx for your confidence :D I still think it's easy to make a conbo lock i can't decode :D

[@lockmania-locks]

Very nice video My Friend

[@Swynndla]

Thanks mate! :D :D

[@levity2893]

only thing on the inside is a round cylinder so why you cant get the tool in nomatter what didgit your one i do not know.

[@rtothes936]

How do all you guys get your thief tools???🤔

[@richardfergison4235]

I have a lock that I forgot the combination how do I get a shim or do I order one from to unlock it?

[@Swynndla]

You can order a shim, which is called a decoder, eg a "sparrows decoder" (and it might even help to file it down a bit, similar to my videos 147 & 148), or you might be able to try and cut a soda can (pepsi or coke etc) like in the last third of my video 118, but you'd cut something not as wide as in the video and you *might* be able to slip it in and lift the lever, although it might not be strong enough, and that's where a proper decoder is good as it's made of strong steel, so even though it's thin, it's still strong enough to lift the lever. If you try cutting a soda can, just be careful not to cut yourself on the sharp edges.

[@Swynndla]

Or with the soda can method, you might be able to use it to *decode* the combination, because if you lift the lever, you still don't know what the combination is! ... so even if the soda can method might not be strong enough to lift the lever, it might be ok to decode the combination by slipping it in the right hand side of the wheels, because it should only slip in properly if you're on the correct number (and you'd try each number on each wheel). Failing all of this, if still not joy, then you could try each combination starting at 0000, 0001, 0002 (depressing the shackle on each one to see if it will open) ... yes it will take a long time, but if you do all the 0xxx in one evening, and all the 1xxxx the next, etc, until it opens then it should only take a few days.

[@gregtunston5162]

super video

[@Swynndla]

Cheers Greg! :D :D

[@dirkdiggler2430]

So lock is useless after you open it or how do u figure out the combination?

[@Swynndla]

The lock still works just fine, and the method I showed is just to open the lock, but I still wouldn't know the combination! I'd have to go through all the combo's to figure it out!

[@dirkdiggler2430]

@@Swynndla 😫

[@noahway13]

Open the lock, steal what you want, and leave... = ) JK

[@jesussalcido]

You need to watch The Picking Lawyer video again, practice a lot and make a new video. Thanks¡

[@michaelhurwitz8814]

I find the fingerless gloves overkill.

[@Swynndla]

Fair enough - it was quite cold where I was when I did the video. :D :D

[@steffen36260]

Poor lock pick got hurt lol

[@Swynndla]

It did! :D :D

[@bladeboysfv5646]

Supposed to be the left side of third wheel

[@Swynndla]

Whatever works is fine. There's some manufacturing variation between locks. Sometimes it's necessary to modify the decoder tool too.

[@1965RonnieP]

Shut up and show us already. I'm out

[@rtothes936]

You're cheating in a lock picking video.
