I'm trying to open my brinks 50mm brass padlock, it's 4 wheel combination lock is easily opened with an ez decoder. but it is a 2016 model with the letter K inside of a square on the bottom of the lock to the left of the wheels, I think they fixed the ez decoder flaw in the third wheel from the left because it does not work like previous models (from my experience). Any picking knowledge or insight or answers would be appreciated.
Note: I think model number is 661-49001
