Good question! I've looked into this a bit myself and I think the best overall match is Akzidenz-Grotesk Condensed, albeit not exact: https://www.myfonts.com/products/condensed-regular-akzidenz-...

The G is different (look at the lower right corner), the 0 (zero) has a slash which looks custom, and the Q is very different (it looks like a letter O with a piece of another O added for the tail).

And yes, since it's the standard comment about fonts, this is a commercial font that costs an arm and a leg.

It looks too nice to have been drawn just for keycaps :(

Kind of ambivalent state of things, a research thread to solve that provenance issue to some degree of certainty is always only one prompt away too.
