The question asks for two keys that cannot open any door. To answer this, we need to think of keys that don't serve the purpose of unlocking doors.

One key that can't open any door is a "piano key". Piano keys are used to produce musical notes and are part of a piano keyboard. They are not designed to unlock doors.

Another key that can't open doors is an "answer key". An answer key is a sheet of paper or a document that provides solutions or answers to questions, typically in educational or testing contexts. It is used to check the correctness of answers, but it cannot physically open any doors.

In summary, a piano key and an answer key are two examples of keys that cannot open any doors.
