Name that could open doors for you (6)
I believe the answer is:
handle
This clue is a double definition.
'name' is the first definition.
'that could open doors for you' is the second definition.
(Other definitions for handle that I've seen before include "Infectious disease" , "Part to be grasped" , "Part by which something is carried" , "Person's name (slang)" , "Touch - deal with" .)
