Make psycho release the door? (7)
I believe the answer is:
unhinge
I believe this clue is a double definition.
'make psycho' is the first definition.
(referring to 'unhinged')
'release the door?' is the second definition.
(Other definitions for unhinge that I've seen before include "turn crazy" , "Madden" , "Throw mind into confusion like loose door" , "Drive insane in huge inn" , "Remove a gate from its support" .)
