Master Lock Directional Combination Lock, Set Your Own Directional Lock, Combination Lock for Gym and School Lockers, 1500iD

i got 3 of them, and i ordered 4 more. i took them apart and found out what is wrong with them, ( problume # 1 ) the sticking dial is fixed buy puting a small amount of novus fine scratch remouver between the larg flat washer and the inside housing and working it till it is smooth, be sure to rinse it good with lots of warm water. ( problume # 2 ) paint chips contaminating the meckanizim, as the shackle is mouved in and out it breaks off internal paint chips, i used 320 grit wet or dry and various drill bits to simulate shackle mouvement, ( problume # 3 ) shaft grease, i took all the plastick parts and washed them good inside and out with erra detergent cleaning the mettle shafts too, infact i washed everything with a toothbrush and plenty of detergent, the hole darn lock, inside and out, after drying every thing i reasembled it, and WOW, i absolutly love this lock, i put epoxy resign in the main scrue hole to alert me if anneyone tries to open the lock. i believe thease locks are failing because over time the shaft grease hardens and the paint chips build up on the inside, not to mention that outside dirt gets in to the lock and ads to the debree problune. i love taking thease locks apart, its like puting a model together and after all the work i have an incredible lock, it cant be picked or shimed WOW. and if it does fail to open i can drill out the epoxy and do it again, i dont reckomend outdore use. . . UPDATE. i got the outher 4 locks, but the screws are glued in, so i will just use them without taking them apart. thay may last years without messing up. if one messes up i will just break it apart with a pair of vise grips and replace it with a new one, comboed the same..

I already have one of these that I keep in my gym bag, and needed a second one for a similar purpose. For me, remembering a directional combo is a lot easier than remembering a numeric combo, and I can open it in one hand. Best of all, you can set your own combo, so I used the same combo as my first lock! So easy!

First off: I wish I had taken the time to read the reviews instead of trusting in the brand. Second: next stop is asking Amazon for a lower than one star selection to be able to submit a review. Like others I got this for my gym locker. I have a traditional combination lock but when I come in from the pool I'm shivering so much getting it open is a mess. This looked, and was marketed, as so much easier. Four little movements that I could make no matter how bad I was shaking. But then... It wouldn't come off!!! I twisted and turned and pulled and pushed and wiggled and jiggled and shook. It didn't budge! If I got the top clear of the recess, the end was caught in the hole (the end of the shank has a section that is smaller diameter with a cap that returns to the regular diameter; kind of I-I shaped; which gets caught in the lock hole). What was I going to do if I couldn't get that locker open? Walk home in my bathing suit!? It was 8° outside! Obviously, I eventually got the friggen thing off. Once I was dressed, I thought maybe a little practice was all I needed...a dozen tries and an hour later it was not a bit easier. I accepted, no matter how much I liked the lock (I had even gotten lucky on the color roulette and got my fav color; purple) it was going to have to be returned. But wait! What? The seller, Master Lock, doesn't accept returns! (I went back to the items page and there doesn't seem to be any information about returns at all) They market a lock for lockers that doesn't fit at least 3 models of locker. And when it doesn't work they respond with: so what; looks like you're screwed! There is a happy ending. I contacted Amazon about the issue and within the hour I got an email promising to do everything they could to resolve the issue AND a full refund! Once again, Amazon's response is amazing reinforcing why I do as much of my shopping with them as I can. Summary: My current lock may be a mess but this Master Lock was a nightmare! In the end though, Amazon came to the rescue.

Amazing lock. Tested from the spring of 2015 to the summer of 2016. Based on the reviews I've read before purchasing this unique lock, I never would've guessed that it works 100% of the time. This lock is a bit thicker than most but that's due to its mechanism and very unique lock structure. Positives of his lock include the ability to open it up with only one hand and it's very stylish metallic body. Along with allowing you to set your own unique "password". Mine currently works with a set of 8 shifts with one shift repeated twice. The main problem that kept coming up during the first week was that the middle knob kept getting stuck on edges such as in the picture I've included. However, after months of usage, that hardly ever occurs unless specifically forced. It's as if it has its own break in period in where you just play around going up, down, left, right in order to get the lock all greased up and loose. The instructions for the lock must be taken seriously and must be done precisely in order to get the lock to remember your "password". This is where I had the most problems. I messed up once and couldn't open the lock with the new password I set. That's until I noticed it actually didn't recognize one of the shifts I made because the lock jammed up during a shift (main reason why you should play around and break it in before attempting to give it a new password). It was able to open up once I tried some variations of the password I tried to save into it. Just follow the instructions and the lock will work correctly. Keep notes of what you've registered into the new lock password beforehand just in case the new password you set didn't recognize of your shifts. For me, the ability to open up the lock with one hand outweighs the troublesome setup and break in, which is why I believe it's worth every penny. Just have patience. PS: For the first few days, I suggest a simple password that doesn't include two of the same shifts, one after the last one, such as up up or down down until your sure the lock is able to make those shifts.

I'm going to start off by saying that the security features on this lock are outstanding. It has an anti-shim clasp, and the method of unlocking the lock via multi-directional dial (with pretty much endless possible combinations) is a genius idea! You pretty much have to destroy (or dismantle) the lock to get through it. I've spoken to an industry expert, and he told me this is one of the best pad/combo locks you can get today. With that said, below is my personal experience with the lock: So, I bought this lock despite multiple reviews stating that resetting the lock combination could lead to permanent malfunction. When I received the lock, I played around with the default combination, and the lock unlocked without any problems. I followed the instructions and changed the combination to a personal one. I was disappointed when the lock did not unlock. I tried my new, personal combination a few more times, and still no luck. At that point, I figured I had a non-functioning lock and decided I was going to return the lock to Amazon for a refund. However, for some reason, I continued to play around with the lock, attempting my personal combination over and over again just for the heck of it (because I knew I followed the instructions perfectly). Don't ask me why I did this, because I wouldn't be able to tell you. After trying my personal combination approximately 10 more times, it unlocked! I thought to myself, "Hmmm... maybe it'll work from here on out!" Not so much. Again, it took many repeated attempts for me to be able to unlock it (same combination over and over and over again). My wife and another couple we were having dinner with made a game out of it and tried to see who could unlock the lock the most. Every now and then, we were able to unlock it. Once we were done having fun with it in that manner, I decided to reset the combination and change it back to the default configuration (once one of us was able to finally get it unlocked again). I was able to successfully do this, and the lock locked and unlocked just fine. I reset it again and changed the combination to my personal combination once again, and now it works perfectly without any issues. I don't know if it just needed to get "broken in" or something, but it seems to work just fine now. As a result, I probably won't be returning it. My suggestion to those who follow the directions and find their lock not unlocking with their new, personal combination is to just keep at it until (hopefully) it unlocks. Then, reset the combination and try changing it again. Maybe, just maybe, it'll start working like it should. If not, return it. With that said, I hope my lock doesn't freeze up on me again should I decide to change the combination (hence, the minus one star for my troubles)... Oh yeah... and another thing. I didn't like the fact that I wasn't able to pick the lock color I wanted (the description states "Assorted colors," leading me to believe Amazon picks and chooses which color scheme they will send out). With four different color schemes in the pictures, there was only one I was hoping not to get. That meant I had a 75% chance of getting a color scheme I liked. I thought to myself, "Those odds aren't so bad." Well, guess what? I probably shouldn't go to Vegas anytime soon...

I've had several of these in service for at least five years in a medium-light duty application: gate locks on several gates on a ranch. They they have been as reliable as any other lock I've used for this application, with the added advantage of requiring no keys, no glasses and no light to open. I soak 'em in soapy water at the end of dusty summer, rinse well, dry and then squirt some Teflon lubricant inside and with this treatment these locks have proven more resistant to icing than the conventional keyed locks. If they do ice up, a few moments in a warm hand does the trick. I just bought two more for two new gates and after seeing the negative reviews decided to share my own positive experience. These are not heavy duty locks, they won't stop a determined intruder, but they strike the perfect balance of security, convenience and reliability for me. Follow the instructions carefully and maybe you'll have as good of luck with these locks as I have. A final note, another reviewer stated all the locks come from the factory with the same combination. This has not been the case with the locks I have purchased. So if you buy in bulk pay close attention to the documentation with each lock so you can open it and reset the combo.

I love it! The only thing is, after I purchased it it said that it could not be used outside and I’m using this in a sheltered location outside. We shall see how long it lasts. I think it’s a little pricey for what it is.

This is my favorite unreliable lock. It's a neat little mechanical toy, but too cheaply constructed to be a good lock. Here are what I consider the pros, cons, important technical aspects, and some troubleshooting tips. Pros: * When it functions properly, it is usually faster and easier than dialing a combination on a typical locker dial combination lock or spinning the 4 wheels of a 4-digit combo lock. * It'easy on eyes that have trouble with little tick marks on dials. * It's easy on fingers that have trouble with little wheels. Cons: * It needs a thorough troubleshooting guide. * Many times it just won't open when you enter the right sequence of moves. * The shackle often sticks when you try to pump it up and down to clear a combination. * The internal components are plastic and cast metal, not machined metal. That's why it malfunctions so often. Technical Aspects: * Even though you can program it with a combination of arbitrary length, there are only 7,500 unique internal states, not counting the reset position. This means an internal state can be reached by more than one combo. For instance, if you program it to open with up-down-right-left it will also open with right-left-left because these two combos produce the same internal state. Another example is down-up-down-right is the same as left-down-right-right. * Any combo with 12 or more moves is equivalent to some combo or combos with 11 or fewer moves. This is because it takes at most 11 moves to reach any of the internal states. (All this info is available in a PDF on the toool.nl site, just Google "toool master lock speed dial"). Programming with a really really long combo won't make it extra secure. Troubleshooting: * Pushing the shackle down toward the lock body puts the internal wheels in the reset position. Several times the instructions refer to pumping the shackle twice in succession, and this is because they know the shackle can stick on the first pump. Well, it can also stick on the first two pumps, which also won't reset it. Pushing it down at least 4 or 5 times really quickly will ensure that it is really reset. * If the lock doesn't open after you set it to your own combination, it's most likely because it didn't properly reset between entering the factory combination and your own. If this happens, the new combination is the factory combination followed by your own combination. * There can be a lot of kickback in the opposite direction if you flick the button too fast. If you flick it to up really fast, it might actually move down below the center for a split second afterward, which effectively inserts an extra move in your combo. When you are setting the combination for the first time, do it slowly so you don't inadvertently insert extra moves. * The instructions say to use the nib of a ball point pen to move the little lever to change the combo. It's better to use something less tough, like a piece of plastic, because the little lever is prone to breaking off. Don't use something hard or metal like a screwdriver or you might break it. Overall I think it's too glitchy to secure anything important, but I do like playing around with it. I hope Master Lock comes out with a second version of this lock made with machined components some day. The concept is great, the manufacturing needs more quality control.
