Most of their locks have the open “A” profile keyway and those blanks are plentiful. I have a bunch of “R” keyway locks and those blanks are impossible to get a hold of but I can modify a different blank to fit them.
Most locksmiths, myself included, can impression a key for the modern WB padlocks but the cost of doing that will usually out weigh the value of the lock. I once had a guy who had several WB modern padlocks that had no keys and he wanted a set of keys for each one of them. I thought I would sticker shock him with the price ($15.00 per lock) but he said they had sentimental value and his initials happened to be “W.B.”, so they were extra special. By the end of that ordeal, I made some money, he got a set of working keys for each one of his locks and we were both happy. =)
