I say check the firmware if you have a non-DTMF firmware and install the DTMF keys. It could also be the electronics are cut out fro nondtmf radios.

No way to do what you want, because chip-resistiors (which installed in DTMF-lines) in PCB of non-DTMF TK-x80 portable radios are NOT installed at factory

Look on your keyboard PCB - you can see places for chip-resistiors.

You must replace keyboard PCB with another one where these resistors installed.
