Cracking combination locks

Here's a video with a concise, complete tutorial for cracking any Masterlock combination lock. You need not destroy the lock, and you will wind up knowing what the combination is. It takes a bit of manual dexterity to figure out the third number, but the first two are trial and error. Somehow, the author of the video has figured out how to reduce the possible combinations from 64,000 to only 100.

This had to happen eventually. Just because there are 64,000 possible numerical combinations in a lock with dial settings from 0-39 doesn't mean that all 64,000 combinations are legitimate cryptographic solutions. As far as I can tell, there are only 4,000 or so legitimate solutions to a Masterlock combination lock, so solving for any one number will cut that down to a size for n that can be cracked using brute force methods. All you need is a few minutes' worth of patience.

I always knew there was a reason to stick with keys...
