Product Description

We’ve outdone ourselves with the 7 pin version of our lock picking practice locks – The Ultimate Adversary Practice Lock.  Pin stack retainer screws make it easy re-key this lock cylinder millions of different key combinations for millions of different lock picking challenges. An assortment of more than 100 extra bottom pins, top pins, master pins, and springs is included.

This 7-pin version of our practice lock also includes three different types of security pins:  spool pins, serrated pins, and T-pins.  Also included is a 5 pin demonstration key with it’s own pins to let the beginner demonstrate a lock’s normal operation before re-pinning the  lock for lock picking.

The key way is a Schlage C, also commonly called SC1.  This key way offers more challenge than our 5 pin practice lock but is not especially difficult to work in.

The assortment of spool, serrated, and T-pins will help you to learn to overcome pick resistant cylinders.  Special security pins are becoming more common every year.  A decade ago, security pins were rare.  Today, even some of the cheapest hardware store brands include security pins to make them pick resistant. Most locksmiths never develop the skills to consistently open these locks. With practice, you can learn to consistently open even pick resistant locks.

Thousands of our practice locks have been used to master the skill of lock picking in over 40 countries.

    Solid lock with a nice bag full of goodies. I’m not sure why it comes with a 5 pin key though.

    Great lock! The only thing I’d echo is Randy P.’s comment about having some sort of chart or diagram that gives a description of the pin # for each color, and the use of the colored wafers for those of us who are new to locksport.

    Otherwise, it’s as advertised, and a great tool!

    Incredible practice lock for a beginner thru advanced. My only con would be no included chart or diagram of what pins were included, or even bag them separately. Not a deal breaker by any means, just a little daunting sorting them as a beginner.

    Very nice product. Includes separate pack of pins plus 2 keys for normal operation. Lots of different pins, different springs.

    Took 3 weeks to get to local post office in Darwin Australia.

    Should keep me occupied for as long as I like. Well worth it.

    Highly reccomend this lock. The lock is really well-made. The tolerances in this lock are so small. It´s the best practice lock out there. For what it´s worth, I have been a locksmith for 42 years.

    Joining the chorus of happy customers. As a novice on the far side of 60, I previously only practiced on random Master padlocks in front of my computer. Success was mostly luck. Pretty frustrating. This practice lock is high quality and comes with an absurd number of pins, security pins, and springs. A lifetime supply for your practice needs. My skill is improving steadily, from trivial 1 pin, to 2, and now to 3. Playing with BOK and TOK tensioning, different picks, etc. While I have a long way to go, I’m happy I chose this deluxe model, which I’ll never outgrow. Frankly I don’t see the need to start with lesser models, just get this one and begin with easy pinning.

    Excellent practice lock for a new picker. I wanted a challenge and got it with the key way immediately. Didn’t take me long to pick all seven standard pins but changing the springs and adding security pins will slow you down. I pick easier locks to get my confidence back then repin the Adversary and start picking.

    Great practice lock. Been weighing buying it for years, finally pulled the trigger, and I’m very happy. Great selection of pins. Easy to repin. I should have bought the cheapest lock, the SC1 keyway is pretty tough!

    Great tool for me as a beginner into locksport. Helping me gain skills at a much faster pace than I anticipated!

    (verified owner):

    Some better guidance in selecting combinations pins and springs would be very helpful. The pin combination that I initially selected was so short that the spring extended below the shear line and got damaged. Some pin/spring combinations required too much or too little force used in lifting the pin stack.
    Like the other reviews stated the keyway is challenging.

    I finally have the set of practice locks, even though i know i dont need all 3. But the quality of the locks and the ease of changing pin combinations is just Awwwesome! Covid Lock down isn’t so bad with one these kits on hand, i recommend the 7pin adversary kit, because it comes with more variety of security pins in the already chocka block bag of extras! Bargain mate!

  14. 5 out of 5

    (verified owner):

    I took the advice of LPL or it might have been BosnianBill to get the 7 pin version as you can start with even just one pin and add pins as your skills improve. I’m not so sure it was the best advice though as yes it is true that you can start with only one or two pin stacks, but this keyway is a chore in itself and I can see that the 5 and 6 pin versions have a slightly more forgiving keyway for the beginner like myself. Having said that, this kit is amazing! The lock itself is very well constructed and seems to have some pretty tight tolerances (again maybe the 5 and 6 pin versions have less tight tolerances allowing for easier binding.??). The assortment of key pins, driver pins and security pins is great allowing for many different configurations and years of practice. As for the person giving only 2 stars because of the difficult keyway, this is the “Ultimate Adversary Practice Lock” not necessarily meant for beginning pickers which is why Learnlockpicking.com has 3 different versions of these practice locks starting with the easiest 5 pin version for beginners and gong up to this challenging 7 pin lock for more advanced pickers to practice with. I gave this lock a 5 star review based on what I received not based on my poor purchasing decision. Buyers beware this lock is challenging in everyway, if you are a beginner my suggestion would be to start with the 5 or 6 pin lock with the more open keyway and when you’ve “Mastered” that then move up to the Ultimate Adversary! Oh, and customer service is outstanding!

    Arrived in Australia in a little over 1 month and I was pleasantly surprised with not only the quality of the cylinder lock itself but with the large assortment of pins & springs including security pins like spools, wafers etc. Very happy I stumbled on these practice locks. Thanks heaps

    Thank you so much for such a quality product! Definitely an amazing investment for the price! While other standard locks I’ve bought from retail stores have become swift picks, this one continues to keep challenging me with still so many combinations to go! Buy it! Hope you’re as happy as me!

    First time lock picker here. Yes a noob over 50 years old. Loved the Adversary Lock, pins, springs, etc. Change the pins regularly up to 4 so I can practice. Have not moved up to security pins yet but I now have the ability the do it with this set.
    I would recommend the set to everyone who needs practice. Now I am on the search for locks missing keys for additional practice. With this set I am learning the feeling of the pins and what picks I can get the best feedback from.

    I decided to pick this up to hone my skills in lieu of purchasing more locks. I like that I can pin this lock with any combination of pins I want. I bought an organizer so the pins are separated and easy to get to.

    If you want to develop a true feel for picking, this is an excellent practice tool. With the variety of security pins this lock will provide hours of fun.

  20. 4 out of 5

    (verified owner):

    Great practice lock! I still suck at lock picking, but at least it’s easier to pinpoint my errors and to find out how to tell the difference between regular and security pins.
    I wish the pins came sorted in a small, compartmentalized plastic box, especially considering the price, but DIY works as well. Fortunately, there are a few designs on Thingiverse that work quite well, provided you have a 3D printer. I printed /thing:796504 as an organizer (PLA, 20% infill, 0.2mm, Ender 3 V2) and /thing:3140402 as a pinning tray (same settings, but 0.12mm layer height because it has more details than a simple box). Works quite well for me so far; the box lid is adequately tight, although wrapping a rubber band around it probably won’t hurt. Bring some patience for sorting the pins and screws, though ^^

    This is the best practice lock I have ever purchased. You have up to 7 pin stacks to set up a large variety of difficulties which will have you picking locks with the best.

  23. 5 out of 5

    (verified owner):

    I ordered the “7 Pin Ultimate Adversary Practice Lock” and 2 “Security Pin Upgrade Kit”.

    All 3 of the pin bags contained about 120g worth of pins, springs etc.

    I ordered this lock because it offers much better tolerances than the progressive locks and revolver from a different shop. Also because it uses the SC1 key for 5 pin keys (same as the progressive locks) or even the SC4 key (6-pin from a reload kit for the revolver), allowing to pin this up with a working key from my other sets and vice versa.

    The lock feels much better than the progressive locks or the revolver from a different shop and has a tighter, more real feel when picking (obviously, because it is a real lock after all).

    There is literally nothing to not like about this product, and the customer service was outstanding.

    Love this set :)

    (verified owner):

    This is exactly what I needed to keep learning. The clear locks are now too easy, but most of the other locks I have are too difficult for my current skill level. I can open them, but I often don’t know why or which pin set last. This lock allows me to customize the experience so I can focus on the feel without wondering about how the pins are configured. As a bonus, I can put it in a vise and apply tension to the back lever instead of with a wrench. This lets me separate picking from tensioning in the keyway. I highly recommend this lock.

  26. 5 out of 5

    (verified owner):

    Nice guild quality and really a lots of pins (I actually try to count them and finished with number 115 and I was only somewhere in 1/4 or 1/3 of full amount :-)

  27. 5 out of 5

    (verified owner):

    Absolutely superb product. Allows you to set the lock to be easy or challenging. If you’re lucky enough to share the hobby with a family member or friend, it gets really interesting. My daughter sets it up and I have to pick an unknown setup and vice versa.

  28. 5 out of 5

    (verified owner):

    I just started learning at the beginning of the year and this is such a great way to learn. The lock moves very smoothly and is easy to use. If you have tweezers, it makes changing pins a lot easier, but it comes with everything you need to start. There are more than enough pins to get a huge variety.

    The only thing that I might like as an improvement is to have a couple of flat sides to make it easier to hold. It sometimes will rotate in my hand and after a while, I start gripping really tightly and my hand cramps up.

    I started with 2 pins and worked up to 4 before I had trouble, so this is a great way to learn where your learning threshold is.

  29. 4 out of 5


    Very good lock with five sizes of bottom pins each size gets its own color gold, silver, green, pink, and purple. My biggest complaint is that the colors of the last three rub off after a while so remember which pin is in which stack. Overall a very good product and a must have for anyone who is interested in learning how to pick locks or wants the challenge.

    (verified owner):

    Incredible!! The tolerances in this 7 pin lock are so small I have yet to open it after 3 days!
    I bought this for its 7 pins as the Sparrows Cutaway & Progressive Locks were becoming too simple (even with their reload kit). Brilliant!

    Great practice lock! Amazing lock construction, and a very good price for what you get. The included security pins and extra springs were also a great addition. If you’re on the fence whether or not to purchase this lock I would just go ahead and pull the trigger, you will not regret it!

    Noob to picking. This has been spectacular for learning. I started with one pin and am up to 3. As opposed to just fumbling around and opening a lock I am actually getting the feel of what I am doing. Spectacular.

  34. 5 out of 5

    (verified owner):

    Well built, good finish, and should offer a challenge for a long time to come. As a newbie, I only filled in four pins to get started and have just recently put the 5th pin back in as I have gotten better.

  35. 5 out of 5

    (verified owner):

    Great to have as I begin to learn, love the versatility as a beginner to start with fewer pins, growing to more pins, and security pins when the time comes. Master pins are a great addition as well.

    Excellent practice lock. Pins, pins and more pins for hours of picking and pinning practice.

    (verified owner):

    Excellent training lock. I actually bought the Sparrows revolver first, but had problems with it not wanting to bind up at all and picked this up to try out. Immediately had much better results, and the other keys and pins from Sparrows were even compatible. The keyway was difficult at first, but now that I’m used to it I’m glad they chose a more paracentric one like the SC1 to use. Definitely happy with my purchase would recommend it to anyone looking to learn.

  38. 4 out of 5

    (verified owner):

    Very good set, lots of pins and easy to change configuration. I do wish the tolerance would be higher though consider this is the most advanced model. Also it only came with 5-pin configuration and key, a blank 7 pin long key would have been sufficent.

  39. 5 out of 5

    (verified owner):

    When I first opened the package, I couldn’t help but quote The Doctor. “Oh, you sexy thing.” Then began the challenge: Sorting through the pins and springs, and allocating them to little bags. There are so many pins that I ended up comparing the company to Five Guys: They give you a certain amount, then dump a bunch more in. I can’t even begin to count the number of master pins!
    All in all, the whole thing is great, and is compatible with my other practice locks. The possibilities are virtually endless, and I can’t wait to try out the T pins!

    This Ultimate 7 pin practice lock is absolutely fantastic!! product, It’s a perfect training, practice lock.

    This Ultimate 7 pin practice lock is absolutely fantastic!! It’s the ultimate and everything I was hoping for. Included with the lock was a more than generous supply of key pins, driver pins, master pins, security pins, and springs. Their customer service is outstanding as well. I couldn’t have been more pleased. I’m going to buy the 6 pin next so I can try a different keyway.

    This is the best practice lock I found in all the searching I did prior to purchase, and it’s proved to be even better than expected. The keyway in the 7 pin lock is a good challenge for me right now, it’s been machined perfectly to allow for easy repinning, and I absolutely love how many different pins the kit came with. A great product all around!

  45. 4 out of 5

    (verified owner):

    Would have been a 5* review except for a few small things. The 5 pin key that was included had such a bad biting that I was able to take it in 3 seconds on my first attempt (with standard pins). Yes, I can make it more difficult with security pins or change the biting, but having a biting that represents what is found in the field would make it more of a “real world” training aid. Second, it came with a 5 pin key yet it is a 7 pin lock. A 7 pin key (like a 6 pin lfic) would have been ideal as you could still populate only 5 pins to give it that real world challenge or load up all 7 to boost your challenge level.

    Aside from that, the lock quality and baggy of pins is excellent.

    I have just received this lock and it arrived very quickly in the mail. Kudos to Learnlockpicking, USPS and Canada Post. I am very happy with my purchase. I discovered the keyway to be tighter than other Schlage SC 1 practice locks that I have in my collection. I don’t know why that would be but it is a positive for me when I am learning feel. I may order the 6 pin version as it has the Sargent L-series keyway to practice on. The bag of pins,springs etc. is fantastic I can see I will never tire of this lock or the combination choices it gives me in pinning. I find also the lock very light to through into my pocket when I go out and find a moment to practice. I rarely use a vice and had no problem in holding the lock in my hand. Two very big thumbs up.

  47. 5 out of 5

    My previous practice locks were starting to get to easy, so I ordered this to help improve my skills. Tolerances are great, comes with loads of security pins, and the keyway provides a good challenge. Excellent product!

    (verified owner):

    I bought it to learn security pins, but it goes far beyond that now I have it. It has some good tolerances, not as much slop as with my old practice locks, they were good and served their purpose. I don’t think I will out grow this lock anytime soon. A quality product, prompt shipping and I would recommend this to anyone trying to further their skills.

    This is an excellent practice lock. I don’t have a clamp, so it took a little while to get used to holding this lock in my hand. Once I got used to the feel, it was fine. You can quickly and easily re-pin this lock for any skill level. So, it grows with you as you become a better picker.

  53. 2 out of 5

    (verified owner):

    I absolutely love the concept of this, but the key way style was a poor choice for beginning learners. I’m spending more time trying to fight my picks into the key way than I am actually manipulating the pins.

  54. 5 out of 5

    (verified owner):

    Lots of good stuff comes with it! Keep you busy for quite some time nice keyway nothing too restrictive; absolutely a nicely machined practice lock. Was worth every penny!

  55. 4 out of 5

    (verified owner):

    It’s a good versatile lock that you can practice with and ramp up or ramp down the difficulty as you need to. the downside is that all the pins and springs come in one bag and it’s going to take you at least a half hour to separate them. if you don’t have a jig or vise to mount the lock as you are practicing, you will quickly get a hand cramp. All in all, not bad and good to hone your skills.

    Great value and well made. Plenty of options and learning to be done with this set. Now I need a small kit to hold all the different pins and parts.

  57. 5 out of 5

    (verified owner):

    I was going between this and the 6 pin version. I opted for this since it came with more security pin options. I almost started regretting it since I started with the 5-pin demonstration key pinning, and couldn’t even find out how to get my pick in the keyway. I dumbed it down to 2-pin and struggled for days.

    I finally figured it out, and was able to step back up to the 5-pin version, then work in 5 spool pins and pick it easily within a week. I love playing with different pinning versions. The keyway is tough, but I was able to figure it out.

    This lock set is exactly what I was looking for. I love the way it teaches me the feel as I add pins. I haven’t gotten to the point that I want to start in on the spools or serrated pins but thye are part of this set when I get good enough to move forward

    The excellent quality i expect from LearnLockPicking is in full effect with this. An wonderful array of pins, an easily re-pinned lock, and a challenge that you get to move up or down in difficulty. Many hours of fun, just learning to re-pin without losing things, as well as picking.

  61. 5 out of 5


    Just got this lock. Love it. Keyway is more challenging than I thought but doable even for me with zero experience. I would recommend a good set of pinning tweezers, those pins/springs are way small and difficult with my fat fingers.
    Mine didn’t come with an allen wrench, no biggie, standard size and I threw one of my spares in my kit.
    I also wish I would’ve gotten a clear lock. While I know how it is supposed to work, the “feel” is what I have struggled with the most. Not being able to see inside makes it a surprise when I get an open. Or worse yet not knowing what an overset feels like.

    Loving this lock so far,challenging keyway and love that you can progressively pin with whatever u want so easily. Only thing I would suggest is a pamphlet insert that explains more in depth on how to pin this lock. As a new picker I found this to be the most daunting part of the process.a more comprehensive explanation of how to pin for the new picker would be great.Ty for making this lock available for us !
