(352) Master Lock 8184D Disc Detainer Bike U-Lock
Bike locks should be strong to resist attack. The Master Lock 8184D disc detainer bike lock...well....isn't. The disc detainer lock is a good idea and is fairly difficult to pick, but the designers cheaped out on the locking mechanism. One or two good licks with a hammer pops these right open.

Oh and by the way the BEST U Locks I have seen believe it or not is the Abus X-Plus Granit 54, the Power and the Extreme! These are still made in Germany and the quality is exceptional!!! I am uploading the video on the 54 right now, I do not have the Extreme yet since it costs like 150€+ but I will buy it one day!
I wanted to comment, I picked up this exact master lock several years ago for my roommate so he could lock up his bike outside his workplace. A lot of the reviews for this lock on amazon and other sites complain about the lock mechanism not working and binding up after being left out in the elements. This happened to my roommate too, but instead of being an idiot and twisting the key off in the lock, he just squirted some light oil into it and it freed right up. The U-lock works perfectly to this day.
LOL I love it how you did not even try to pick it; went straight for the hammer.
You just shattered my confidence in this product.
It's nice to see that when a product from a company that you know to make a large majority of garbage actually tests to be "not the usual garbage", you give credit where credit's due!
Thank you for this! I had this u lock locked to my bike for months and was able to get off after watching. Brute force for the win!
Adrian, I didnt mind at all. I thank you for the info and look forward to any extra I do you put out there.
Nice work bill just want to say I love your videos and I have learned a great deal from you thanks and keep'em comeing
Their design would work better if the u part of the lock could stick out the bottom of the crossbar and instead of having a cutout in the rod which weakens the rod have a hardened toroidal nodule on the rod and inside the crossbar have a hardened latch that turns 90 degrees when locked to latch onto the toroid. Once locked if manufactured with decent tolerances that design would be very hard to break with a hammer if properly case hardened.
Thanks got the lock off my son's bike!
why dont you do some krptonite ulocks?
That's potentially Masterlock's best lock, asking for anything more is like asking a limping man to do a high jump.
Hilarious .. The professional Beat-Box subscriber request appeal .. The cat is not impressed .. !!
Very nice
I'm guessing you need it for securing a bicycle. I was in Performance Bike (a chain in the NE US) looking at the U-locks about a month ago. The OnGuard disc detainer models look AWESOME. Tough locks, hardened steel components, and rubber weather covers. If I was in the market I'd take a serious look at them.

Well, I FINALLY got around to affording an Onguard. They are just as good as I thought and you can see the test video here: kzread.info/dash/bejne/rGFqtqRvl9XLlrg.html
Holy, that beat boxing
Now that is a big FECK OFF vice mate.... Oh, great bashing as well my friend
Hey bill well done video! What thieves do is they try to twist the U-Shackle with a crowbar or use a bolt cropper like the one you have used on the Commando Lock. The locking mechanism is the same Chinese disc cylinder than on my Untouchable padlock and the Kryptonite Fahgettaboutit lock I believe. Could keep one damaged lock for me so I can take the cylinder apart and take a look at it? This way I do not have to take apart one of my expensive locks. I do not need the shackle!
lol wtf was that thing at the end
Could you grind the sharp part off?
I brought a lock for my bike and I was told it was so secure that the police use it and they offer a gaurentee that if it can be broken into, the police will buy you a brand new bike. Can you test this lock out picking it. The model is master Lock 8195EURDPROCOLWS it's rated A+ I can't find anyone who had attempted this lock on KZread
Hey Eric hope you do not mind me commenting on your comment. These disc detainers are made in China but are far better quality than the really cheap ones. Kryptonite uses the same I believe (the one I presented) and also the untouchable padlock I presented should have a similar mechanism. If bill can keep one for me I can take it apart and we can compare it to an Abloy or an Anchor Las or Abus, since I have all of them here.
Well in your defense Bill, smashing a masterlock with a hammer did look like ALOT of fun!!!
Hmmm, I wonder how well a hydraulic jack would work for a slower albeit more quiet entry. Would the slow force eventually shear off the locking tabs or just bend the shackle?
Were you ever able to pick this lock open? I am guessing no, since I couldn't find a video of you picking this lock.
bosnianbill hello,I got a smaller one with chain (rated 9/10 master BScale), and I would like to know if the disc detainer is somewhat useful? (the locking thingy is a lot bigger on mine)
What if you ground off the schakle's sharp edge? Make it a bit roundish. Would it make less wulnerable to shearing?
You know what works faster? Liquid nitrogen, or similar super-cool fluid, and a small hammer on the hardened steel :D Or heating up with a relatively weak torch, then hitting it with liquid n2... even more fun, like cracking a mug by putting hot coffee in, and then ice water right after...

Grim Dark End faster than 3 hits with a hammer? Not even close
I've used a small jack from the trunk of a Honda accord to bust em open it works on all kinds and small bottle jacks work just as well but are are significantly heavier to carry, I'm strictly legal as a reformed professional car motorcycle boat, well anything with an engine thief, now I'm a professional repo agent that works with a few security companies and law type organizations to impede the attempts of dishonest people and completely deny their entry, and they friggin PAY ME real money to do it and the law is always on my side!!

Excellent! What a constructive way to use your life experiences to make things safer for everyone. Congratulations and thank you for...wait for it...."stay safe, stay legal". Kind of nice to use your expertise and not have to worry about some pissed off owner clubbing you with a baseball bat, huh?

+Bosnianbill oh it it nice and Thank You! sometimes the people getting their vehicle repossessed get very angry and wanna get violent but I usually have a police officer on scene to stop that and if that's not enough I can always rely on my lil buddy on my side! but yes I do my best to stay safe and I'm ALWAYS legal!
Bill, I have done a ton of research on locks and have been watching your videos for months. I realize you are one of very few people who can get past locks of the caliber of the challenge locks you receive, but it seems picking is the least common method of opening a lock for theft. I have been the victim of bicycle theft by thieves who bolt cut/hammer the locks, chains, and cables I have used. While I know there is no lock & chain that will PREVENT theft, based on the experience you have had with all of the locks you test: what lock/chain/cable situation do you recommend for minimizing theft of a bicycle from a public bike rack? Thanks!

Sorry Matthew, there are too many chains for me to possibly keep up with. I recommend checking one of the high end bicycle forums and posing your question there.

combination - I'm thinking to buy two small or maybe even three U-Locks from Kryptonite, OnGuard, and Master Lock. and/or maybe U-locks from ABUS and Cocoweb. And get their Thief Protection!
This made me a bit sad, but it's good to know.
try the same thing with master lock 8195D ) do you think master lock 8195D is secure? Thx

SVETOGOR if I learned one thing from this channel: stay away from Master locks.
I've got a question about staying safe, I would like the communities opinion on a decent bike lock, reasonable security and with keys that can be duplicated. I would prefer a cable lock, but I realize that they aren't too secure.
I realize that this is really old stuff but... If you read the reviews via Amazon a lot of people complain about the key breaking off. Somehow I don't think that is a very good application for a disc detainer lock. Rain, corrosion, dirt and some of the keys for disc locks I've seen are quite weak where the actual bitting is done. If you still have some keys around it would be interesting to know how easy it is to twist one off...
hey bosso i would like to stay legal but possession with out a locksmith licence in my state is illegal (to the best of my knowledge), but i will defiantly try to stay safe. thanks from the AU for the great videos!
What if it's facing the opposite direction
In fairness like bill said...Tru the hanging part causes it to be quite harder to hammer break....
We'll find out tonight...
try a car jack !
I want a your pick set
is this model shim proof?
Question, could you grind the sharp edge off that shackle? just enough to keep it from shearing it off? And I agree, if its against the bike its gonna be hard as hell to even swing the hammer let alone hammer it that hard. Hows the quality of the lock itself?
Bill, can you or did you ever pick these, I know its a stupid question to ask !
So the place where you are hitting is also the place that's connected to the bike so I'm not sure you actually are correct here!
dat beat box
I hope we never have to find out...
Hmm I find it kind of odd he didn’t pick it. How much you wanna bet he pulled out his disc pick and realized it was rear tensioned. Because I ran into the same problem lol.
He didn't need to pick it because he was able to quickly get into it with a hammer lol
Thanks. My wife lost the key and my 14 yr old wants to ride. Problem solved.
I subscribed, I subscribed! I'm legal too!
my respects to you BosnianBill, but give a manifold spreader, watch my show and tell me again these masterlock ulocks have security in them.
The paper cover was harder to bust than the lock.
Good Ol' BFH use # 450248 a lock " bypass " tool!!!
Omg, just send the beatbox guy after the lawbreakers...
Maybe using the handle instead of the head (handle should be pretty solid for this of course!) Something like this: s1.directupload.net/images/140327/e4jc6kcd.png
Do you think the disc detained is more comparable to the Chinese junk you picked in another video or closer to something like abloy?....I think I know the answer but surprise me. You don't look at all like I had imagined.....well maybe a little.
I've seen something like this at Wal-Mart.
