I would check, but I gave away my last non VT180 DEC terminal.
I stand corrected. I keep a VT420 on my desk with an LK421 (the "Unix"
keyboard), connected to my workstation (now via a USB serial adapter). I
just popped the keyboard and it is, indeed, an RJ11 for the keyboard.
Serial is MMJ, which connects to an MMJ<->DB9 converter which connects to a
mini null-modem to the USB adapter. So simple.

I'm most familiar with the earlier VT models that use MMJ connectors for
the keyboard (and RS-232). That's kinda nifty, though.

I start v7 Unix and play "Hunt The Wumpus".
(I finally got it put together this weekend, and fixed the last couple
dodgy joints tonight).
IBM keyboard on a vt520?
