Master Lock 1520D...need help.

[chris1]

Hello..
I need some help on picking a Master Lock 1520D. It is different from the normal combination lock, it is a lock where you can set your own combination, how would i go about to pick this type of lock? The full name of the master lock is the Pro-Sportâ„¢ Resettable Combination Lock.

This is an area that I have started to venture into. I want to start on safe manipulation and have done a bit of research on it (Currently trying to get into advanced).

There isn't really anything close to the MIT guide out there for combination wheel manipulation but here is a few good things to read/watch:

1. The video about Mr. Sitar on discovery channel. I found a good working link not to long ago somewhere on this board and downloaded it.

2. Howstuffworks.com (I think that is right) has an excellent explination of how combination locks (It is moreso meant for safes but they're closely if not exactly the same - minus the precision on better safe locks) work. Safe manipulation on a search function there should give a good feedback.

Even with those two sources you're looking at many hours of practice before you will be able to open combination locks. So if you're looking for a quick method for some malicious reason then it won't happen.

Something I forgot to add: That master combination lock breaking image file that has the numbers in it does not work for me. There isn't really any shortcut that I have found out but I haven't made a book yet though so I'm not the expert. The numbers on that chart weren't correct for the first combination lock I tried so I wouldn't rely on anything but feel and sound.
