Are all Bally/Williams backboxes keyed the same?

[Pop Bumper Pete]

Probably a silly/obvious question
But, were all Bally/Williams DMD era backboxes keyed with the same lock?

I was searching for the keys to one of my machines I had in strorage
I found a box into which I had just tossed keys into with out labeling them
Tipping out the box I found 4 sets of keys that all had the same notches and 0001 stamped onto them


So were all B/W backboxes keyed the same?

Thanks
Pete

All mine are numbered differently. Orig locks. Same style n colour key but different number ranges.
