Your CAD animation is amazing! There's no other better way to explain how this lock works on the inside. Truly genius! Thank you very much for putting this presentation together. Can't say enough good things about it.

I cannot thank you enough for taking the time to give to the community and helping people and me with this for so many years to come. I saw a very old lock picking video with graphics but it was on VHS but no one does it. I’m so happy you did. It helps so so much. You’re a very good teacher.

Well done sir! The 3d visual is a masterpiece. Why it's not more widely used I have no idea. It's the perfect thing for showing and not just describing the inside of a lock, especially these pesky things. Top of the class

I know it's been a year since the upload but just watched your video after struggling for hours... And finally got my first open thank to you. After watching your video I noticed that my lock was rear tensioning and tried to use rear tension and BAM it opened... Best feeling ever thanks man!!!!!

that 3d model was fantastic! Extremely helpful in understanding what's inside the lock.

Excellent tutorial, I've learned a lot from this video. I've been struggling with disk detainer locks for a while now. Thanks for the video

Excellent vid. I plan on getting into DD's someday, though strictly for hobby= as you almost never see them used in America. Also, as a fun field of study= Wafer Locks. They're literally everywhere and they have been around for ages and they are a very interesting topic. Disassembling them and reassembling them is very interesting too. Would love to see a comprehensive video series on those. Also= TUBULAR Locks. So little has been devoted to them and they are such a fascinating field. I don't fell like they have even had tools made for them. I mean, they have impressioners but those don't work very well. Would love to see better tensioning tools for them and a pick created specifically to push down the pins. You think, 'Oh, I'll just grab anything' but a lot of tub's have a rim over the pins which makes accessing them super difficult. Like even with a .015's it's hard to insert. The tool should also have a cup to go over each pin, it'd make it easier. (Kind of like Noobs' Monkey Paw but not bent). Would also love to see a demo of the ACE brand impressioner but it's like 400$ lol and not sure if they have different heads for all the different types. 7 pin/ 7 pin offset/ 8 pin/ 10 pin. They're used on tons of things but it hasn't been thoroughly vetted as far as I'm concerned. Anywho, thanks for your efforts. (Gonna get me a silver bullet one of these days, lol.)

You have earned a very well deserved subscription - brilliant video and tonnes of hard work putting this together. Very much appreciated. 😊

This is the only video on YT that can make me understand about disc picking. Thank you sooo much, Sir! 🙏

This was very useful, thank you. Both the model and the 3 mistakes.

The struggle is real. Thank you for this. I didn’t know I could adjust that tip.

Fantastic video. I've struggled with disc detainer locks. Hopefully your tips will help me.

Great video, thank god for great minds actually putting real tutorial videos out like you! thanks jon!

Thank you for putting in the time and effort to put this information together. Working on getting my first DD open.

Absolutely spot on tutorial. Sent over by Chris Capune. Cheers Jon 👍👍🍻🍻

such nice work on the three dee - thank you for the time into this to make this happen.

Great video. It's the best disc detainer video I've seen, and I've seen a lot.

How have i only just discovered this video! This is an amazing way of explaining how the lock works and love the explination really nice work mate!

Great advice and very helpful! Thank you for taking the time to do this! Take Care ⭐️

Best explanation of how it works I've found so far. Including LPL. Hats off to you!

Incredible tutorial!, very helpful!

Excellent video. You have answered many questions I had. Your animations are great and very helpful. Thank you for this video.👍🦊

Awesome video, I been struggling with picking disc retaining locks, I have the very same pick as you and I have been very frustrated trying to pick, now that I watched your video you have given me hope that I will succeed!! Thank you again, lot of work was put in your video, well done!

Great video, felt like it belongs in an educational series. I love DD locks but have had problems and now this vid has renewed my interest back in practicing. Thanks

Great job Jon! Even though I already knew about the topics covered. It was still really entertaining and well put together! I'm sure this will really be helpful for people new to DD picking. I sure wish it was around when I started DD locks.

This helped. I just opened one that I struggled with.

Excellent video and thank you for sharing your hard work and generous knowledge.

Thanks for the video. It's a good reference for when i move on to DD locks. I'm still at the beginning of picking and having fun learning spp. Looking forward to seeing more of your videos.

Thank you for this video, excellent information and animations, I did a dd lock a few months ago but I haven't done anything with it, your insight helps to get the right locks and tools to get started in learning about these locks.

Brilliant tutorial Jon and perfectly timed for me! I’ve just bought a Sparrows DD pick and 1 lock off eBay and spent about 4 hours without any success picking it. I sussed out problem points 1 and 2 myself in the trial and error process but never twigged that just because I got tension off disk 1 it might not be a front tension lock. It might just be me being rubbish at this but I’ll revisit my lock with this newly discovered knowledge with a glimmer of hope once more. Thank you

Very illuminating! Thanks!

An excellent video, with concise explanations. I'm now subscribed...

WOW, nice video really amazing that you put in the effort and did a 3D-model. Nicely done! ABUS X-Plus cores are always front tensioning, they give very good feedback and a lot of people use them in their bike locks you can get lucky from time to time to score one with a lost/broken key (got 2 like this for 1€ each). Obstacles on these are only: False gates, slim spacers (needed to modify the sparrows picking tip a little) and this disc lock thingy before you start (easy to overcome though)

Excellent explanation, thank you

Hey Jon, nice video. For those looking to get into DD picking there are a few things I would recommend. First, find a lock that has been picked a lot and learn about it before you pick it, it's really helpful to draw from specific, collective knowledge. Second, using learning aids can really help, I've used combinations of cutaways and spacers to get better feedback, particularly for new or homemade tools. There are a few models of spacers I have made in the discord which reduce the total discs in the lock so you can get a feel for traversing the lock with better feedback. Cutaways for abloy locks can be done easily (particularly for the classic) which help to validate that what you feel is being translated to the lock correctly. Finally, just a small nitpick, the spacers in DD locks are reasonably important to the picking process. You need to be able to orient your pick in the next disc, that would be significantly more difficult without spacers. For that reason, the pick tip cannot be thicker than the spacers, thus they cannot be neglected in a deep dive on DD locks.

I'm soon going to try my first DD lock, and this is a very informative and detailed video. Thanks!

Great video jon, very informative. 👍

Thank you! This was very helpful 👍

It was excellent explanation how work the disks platform lock . And nice tool too !!!))) The Bestest !!! Good luck.

Great job!

Nice video! Very informative.

Great content. Glad I found your channel via Reddit. Now subscribed.

Awesome video!!!!! Really great !!! You give us X-ray vision 😀 Thank you so much!!!! 🐈🐾🐈‍⬛🐾👏👏👏👏👏🍻

Brilliant video thanks 🙏

Great video! Thanks

Very nice!

Do you have lock brands and models that I can try. Thanks for the tutorial. I’m intrigued by this type of lock.

Hi Jon, first of all great information and animations. For the rear tensioned locks, you probably should have watched some of LPL's Videos. He developed? that technique to open those rear or mid tensioned locks using the Pick that he made together with BosnianBill :)

Great informative video wish my how to DD video was that good lol I like you struggled with DD picking and found the biggest help was some spacers I designed and 3D printed (ps they fit onto the round holes in the sparrows case lol ) I’ve made loads hot people it seems to be on of the hardest things for new DD pickers

Decent explanations, nice graphics, however, here are a couple of things that may help. 1. File the tips of the turning head a little longer. On many locks, you may have a thick spinner to get past before you reach disc 1. Take a look at the turning tip on LPL's pick. LONG fork on that thing, easily filled into shape, just do it gradually, and only by hand. A dremel will heat the metal and destroy the temper, even if you manage to not over grind the turning tip. Also, you may have to shape the picking tip a little to get past the warding of some DD locks. Try not to take off more than you need to. 2. rather than trying to 3d print something if you don't have facilities, a small washer or two will also do quite nicely to help you maintain alignment of your pick tip. 3. The shaft of the turning tip is square, so you can rotate the turning tip 90º, to make your tensioning easier, depending on the orientation of the lock. 4. False gates. Many disc detainer locks have false gates on the discs and will require a lot more work to find the true gates. However, much of the principles are the same, rotating the binding disc until you find a gate, and moving on to the next binding disc. It may not, and probably will not be a linear process as you go through the stack of discs. Once they are in gates of any sort, then you will have to keep searching for the true gates. 5. Do not get discouraged, do not quit, you can do this. It may take a long time at first, but you will get it if you keep trying. If you don't, you will never get through them. Putting them down and waiting for a day when you feel like it gets you no closer to getting them open. Trying, getting frustrated to hell, putting them down for a bit to cool off then coming back to them DOES get you closer to open ing them. Disc Detainer locks are NOT easy to open, and they are not supposed to be. I have ones I still have yet to get an open, and have been trying for years. My first disc detainer locks were kryptonites, because I could find nothing else on hand, all center tensioning, and not easy, but through determination, I got most of them open, eventually, even designed my own disc detainer pick, which you can check out my tutorial vid on. I hope these tips help.

What force is acting on the sidebar to create the disc binding?

I really don't fully understand. Could you type out how to pick a rear zero cut disc detainer lock with a front disc tensioning disc pick in basic steps.

Is there anyone who sells that stabilizer?

i use one of those cheap 5 pound rear tensioning picks just ground down it opens every chinese lock i tried so far still no open on my abus plus though
