As so annoyingly often happens, I'm down to two clues on which I'm stuck.
4 across: Clocked if this would be locked? (

Letters: U - - - E - E - Seventh letter
could be W
And with the third letter as first of:
5 down: A man makes dinner for these ladies (

Letters: - - R - S - E -
I've been trying out a variety of letters but so far, no luck.
Maybe KEYED for the second half of 4 across, but a couple of hints would be much appreciated.
