Giving away a key ring (8)

I believe the answer is:

offering

'giving' is the definition.
(offering is a kind of giving)

'away a key ring' is the wordplay.
'away' becomes 'off' ('off' can be a synonym of 'away').
'a key' becomes 'e' (I've seen this in other clues).
'off'+'e'+'ring'='OFFERING'

(Other definitions for offering that I've seen before include "Gift presented for acceptance" , "Oblation" , "Tendering - sacrifice" , "Sacrifice to deity" , "Religious sacrifice" .)

I've seen this clue in the Evening Standard.
