Keys uncovered strip (6)
I believe the answer is:
denude
'strip' is the definition.
(I know that strip can be written as denude)
'keys uncovered' is the wordplay.
'keys' becomes 'de' (I've seen this in other clues).
'uncovered' becomes 'nude' (I've seen this in another clue).
'de'+'nude'='DENUDE'
(Other definitions for denude that I've seen before include "Uncover" , "Dundee (anag.)" , "Clear so that nothing is left" , "Put off covering" , "Strip, deprive, of" .)
