One less lock in the landfill!

Over the weekend my daughter asked me for a new bike lock. When I asked her where her original bike lock was, she presented me with a locked Master lock. "So...????", I asked. She reported she had forgotten the combination. Hmmm! Well, I pondered and played with the lock for awhile and then decided to search the Internet. Sure enough I found a math algorithm for opening the lock. It narrowed the lock combo possibilities from 64,000 to just 100. On the 97th combination, unbelievably, the lock opened! Granted it took some time to do but like I said...one less lock in the garbage!
