Product Description

The 6 pin version of our lock picking practice locks.  Pin stack retainer screws make it easy re-key this lock cylinder to thousands of different key combinations for thousands of different lock picking challenges. An assortment of extra bottom pins, top pins, master pins, and springs is included.  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.

This 6 pin Challenge version of our practice lock also includes an assortment of spool pins so you can 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. The most common type of security pin is the spool pin.  Most locksmiths never develop the skills to consistently open these locks. With practice, you can learn to consistently open even pick resistant locks.

Learn to recognize the feeling of a “false set” when a spool pin binds the cylinder and how to reduce tension and rotate the lock back toward the locked position to release the trapped spool pin.

The Ultimate Practice Lock Products were invented right here and were the original products offered by LearnLockPicking.com.  Today, thousands of our practice locks have been used to master the skill of lock picking in over 40 countries.  For more information on our most popular products, you can visit our Ultimate Practice Lock page.

    I really wanted to love this product, but I can’t get it to work properly. I am able to pick 6 pin standard deadbolts all day long, but I can’t even rake this lock open with 2 or 3 pins, let alone SPP. It has something to due with the different pins heights as the pins are not binding or setting properly. I have played with every color of pin length, different springs, etc., but I have still not been able to arrage a simple 2 pinset that will function properly.

    As a product designed for a beginner that has presumably never keyed a lock before I find it a huge drawback that the pins are not color coordinated in a way so that it prevents making your pin stacks too short or too large. The company knows this is a problem as they warn against it in their little instruction sheet. It’s ridiculous that I have spent this much time just trying to get the pins to work in an order so the lock will function and I can practice. I work in construction and rekey locks all the time so why is this one function so badly? I should have just bought a $25 Masterlock 911 and repinned it with whatever I wanted. It would have saved me a lot of money, time, and frustration. Extrememly dissapointed in this product and do not recommend.

    Newbie here. This is great when you first start because it allows you adjust the difficulty level just right. My wife and I are learning this together and we are both enjoying it.

    Not an easy lock. I have been picking briefly, but have mastered easily the clear lock, the master and abus locks of the world, and am having difficulties with this one. Which is what is supposed to happen.

    If you can already lock pick well, this is not for you. Get the 7 pin, which is just evil. But the 6 is a superbly made and designed device, and it is going to continue to teach me how to pick locks.

    Very nice product! This is actually my second LearnLockPicking training lock. I bought the 7-pinner first, and love it, but wanted to try a different keyway, since most of my locks have the Schlage. As it turns out, the bitting on this one (for the key that came with it and standard drivers…natually you can change it) is more challenging than my 7-pinner! Love it!

    Bought this item recently. Great way to learn how to pick locks. Unfortunately the finish was fairly poor, the face’s coating had chipped away in places prior to arrival and there are also a couple of minor cuts in the brass. Overall I’m a bit disappointed with the finish but it does what it says it does so thats cool i guess.

    This is a great product. It has made easy to transition to picking multiple pins. You receive a great many pins to build up numerous combinations. It is a great kit.

    I discovered these via Bosnian Bill’s website & youtube channel and bought two. (One for a friend so we can set each other little challenges and swap locks every once in a while.) I’m very happy with mine. I’m pretty good at picking all five pins of the “default” setting that came with keys and have just started to try other random combinations of pins. Fun!

    Excellent lock for training great job guys.my only gripe would be that I got more wafers than driver pins by a ratio of 2/1.but nevertheless would definitely recommend this

    Not disappointed. This lock is exactly what I hoped it would be. I also ordered the “security pin upgrade.” Along with all the pins it came with, this should keep me busy for a long time to come.

    My 6 Pin Ultimate Challenge Practice lock arrived this week (prompt delivery thanks). It’s a fantastic quality product. It’s like the Lego kit of practice locks. I love the way I can configure it in so many different ways with different levels of difficulty.

    Well worth the money. Highly recommended!

    Exactly as described, loads of spare pieces for future fun. I can’t think of a better way to learn this art. I can rake many locks now but am stuck still trying to single pick just 3 pins on this lock. Maybe someday I’ll get to five?

    Very impressed, great way to learn. As a novice I was able to start slow and get a feel for manipulating the pins. Now I spend most of my free time trying to stump self with unusual and difficult pin stack combinations. Couldn’t be happier with the product and the service provided.
