Good lock but it wasn’t factory set to “0000”. Probably been used before then returned and not reset. I had to watch a YouTube video about cracking lock codes. Bad news is your lock might not be set to “0000”…good news is you might learn a new life skill on how to crack codes like I had to.Need locks for your travel pelican case! These work! TSA will screw them up from time to time with their key. Just walk to security and have them fix it. That 007 key is the bane of these things existence.I was genuinely surprised at how easily we can customize the code for these. They are well built and solid as a rock.Item was as described. Hope everything goes well on my trip.producto indispensable para viajes, cajas de transporte rigidas, cortinas de bodegaIt wont stop any criminal but good enough for TSASo this is a week later reviewI traveled last week with the lock on my luggage but to my surprise TSA broke the lock claiming this is not approved by TSASo I lost $22. For nothingPlease refund my money.Thanks.ordered these from the amazon warehouse. received them and tried to use, but they were locked. generic combo did not open the locks. previous owner must have coded in his combo and returned them after using them. amazon warehouse never checked to see if the generic combo worked. very disappointing.It seemed to be a good lock at first. No no real issues with it. It went on 20 airline flights and seemed ok. Now after trip 22 I count my Seahorse tool case back and there was one lock missing and the other smashed. The lock body was missing but the shackle was hanging around. These locks are on the larger side so I figured it would happen eventually. Otherwise no a bad lock. Opened every timeHad a smaller similar lock but had trouble seeing the small numbers so upgraded to this lock.Can see the numbers much easier. Sturdy lock. Please with my purchase and use it regularly at gym.Seems strong & well built. I used it on a Sportube & had to slightly increase the hole in the case but no issues.Recientemente mi hijo viajo al extranjero y el lugar donde estaría hospedado no ofrecía caja de seguridad y es indispensable poder tener documentos como el pasaporte y tarjetas resguardados en un lugar adecuado durante este tiempo por lo que compre este candado para junto con una caja hermética para resguardo de electrónicos y un cable de seguridad armar una caja que pudiera asegurar a un mueble en la habitación, si bien no es igual que una caja de seguridad es una muy buena alternativa para tener seguras tus pertenencias. El candado es lo suficientemente fuerte para el uso que tenía en mente, también se puede usar para asegurar equipaje y tiene la bondad de que se configura facilmente la combinación para no tener que andar cargando llaves.Let me start by saying this: I'm NOT a fan of the "Set your own Word" locks...For the price of $30 + the quality does not seem to be there, I would have liked a solid one piece body which Master Lock is known for. The shape is supposed to be specially designed for hard cases... These locks get stuck in my 8 hard cases and I have to wiggle it out and apply some force to remove.However, aside from these... the only other option to this is the (ASIN: B00W6D99B0) Nanuk Search Alert TSA certified lock which is specially designed for Nanuk, Pelican and Storm hard cases (which I also own) and works way better but the price is a killer ($36 / each)It is good for its purpose, but I personally find the lock (metal part) to be too long for use on the Pelican 1535 air. I do still use it, but the lock I put near the wheels keep getting smashed on the ground whenever I stop rolling the case and try to set the case upright. As a result, the lock is getting worn down.
