Girl runs along with a bunch of keys (7)
I believe the answer is:
rebecca
'girl' is the definition.
I can't explain the rest of the clue.
(Other definitions for rebecca that I've seen before include "Maxim she betrayed" , "Isaac's wife" , "she loved Ivanhoe" , "One of the four matriarchs of the Jewish people (anglicised)" , "Daphne du Maurier's antiheroine" .)
