This was not on my bike but on my locker at work. I've used the same Master spinning combo lock for many many many years.....since Jr. High school. I've used it for the side fence at home through rain and freeze and never oiled it....and then brought it to work. It used to NOT UNLOCK at times and it
was because the tumblers must have shifted. The middle number was off by one or two and after a while I just pretty much put it to the
vicinity of what the number is...it would open.
Till one day the whole spinner thing just fell off.
It was officially dead.
So I bought another one.
