The telegraph was keybased - only one key so I can't call it a keyboard, but in other ways it is what you are asking about.

Pianos have keys. And some telegraphs were outfitted with piano-like keyboards with one key per letter. Wikipedia has some pictures in the printing telegraph article [1]. So there is arguably a clear lineage from pianos to the modern computer keyboard.
Pianos however don't really have a concept of advancing the line or sending a recorded message.
