When did Snap-on start marking / stamping their keys?

[MattVette89]

I got a few extra lock/key sets in a box of tools. Obviously older SO boxes were not made by them so the locksets were outsourced as well. When did Snap-on start putting their logo on their keys? Can anyone identify these locksets and would they have been correct Snap-on "factory" parts for whatever era they were sold in?

Thanks.

I've got keys for 1980s Snap On boxes with the logo.

Thanks. By the 80s Snap-on was making their own boxes so that makes sense.

I've got some '70s boxes, I can check the keys tomorrow.

1980's boxes had the keys you have above and those ran into the 90's. mid to late 90's they changed the locks to the round keys with the snap on logos. my 1994 KR box had those keys. my 1999 box did not.

Great info, thanks.
