Worked but could improve I already did my lock using a pen and paper and math. I wanted to see if the app would make it easier. Which it def does by having all the possible combos. One error is you list combos that wouldn't actually be combos because there are only 64 possibilities not 100 because there needs to be a certain gap between the 2nd and 3rd numbers to work. I wish there was also a table available to see all combos at once instead of clicking through the app.
It really works I had to adjust some of the "stops" after the app said there was an issue but once you make the proper adjustments it gives you a series of possible combinations. It does take a while to go through them if the right combination is one of the last presented but IT REALLY WORKS. I just opened two old Master locks. It saved me from borrowing my neighbor's bolt cutters and buying new locks. Have patience and it should work.
The first great application ever It works give it a chance get your stops right and your half way there it does work using this I am going to do a YouTube video using this soon justaguy357 look for it soon
Kept rejecting my very precise numbers Kept saying it couldn't use the numbers, though I figured it out myself using the divide-by-4-and-use-the-remainder method and the same sticking points I entered in Lock Hero.
Good Second time I've had to use it and worked both times had to redo my entry a couple times but still only took a half hour.
LOCK HERO IS A GREAT TOOL I purchased a lock and tried what the instructions said to do. The lock was opened less than 15 minutes. You have to enter the twelve points accurately. Never looked at the combination of the lock until it was open.
Door screen lock is an amazing, stylish and secure locker for your device.
