No, that is not the definition of a weak key.

Look at DES weak keys, for example. They are simply keys for which the
encryption and decryption transform are identical -- encrypting twice
with the weak key returns you to the plaintext -- but they are not in
some way obviously detectable without trying them.

Might I suggest reading the literature on this before discussing it
