Hey folks.  Just a quick question to anyone else who has successfully replaced your CH751 lock sets on a T@B 400.  What is the tumbler size required?  I broke a key off in my water access panel lock while camping this weekend and need to replace both the key and lock, and thought maybe I’d do them all while at it, possibly changing the locks away from the universal CH751 lock set.  Any recommendations would be appreciated. Thanks in advance.
