As they say, there are no stupid questions. There are not always every model in the IRDB. You can try the latest codeset listed at the bottom of the list for Panasonic. It will have a number (not model number). I believe Panasonic 13 is a codeset that will have discrete power and input commands as well. That codeset will not have menu, exit, directions buttons...

Panasonic codes have not changed much, so you could also use another model number. I have programmed the VT-50 series with no issues (really haven't had issues on any Panasonic of the last 5-7 years). You should be good to go.
