Servants having keys to some place (7)
I believe the answer is:
lackeys
'servants' is the definition.
(I've seen this before)
'keys to some place' is the wordplay.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'some' indicates the central letters.
The centre of 'place' is 'lac'.
'keys' after 'lac' is 'LACKEYS'.
'having' acts as a link.
(Other definitions for lackeys that I've seen before include "Servile followers or archaic servants" , "Sycophants" , "Flunkeys" , "Footmen or servile followers" .)
