Simplex 5120 Programming Tool

So I was somehow able to pick up an item I have never seen before and looks to me like a security key to access Simplex panels. I have posted a picture of it and what panels will it work with, if any?

My picture didn’t upload for some reason? Here’s the link

That key was supplied with the programming software which came from Valcom. As far as I know it only works with the 5120/30 programmer. Later versions of the software did not require the key.

Thanks for that. I was kind of hoping it would work with a panel but that’s alright.
