Garden shed padlock is refusing to badge.

It is (or at least looks like) one of these:

Had it for 10+ years, giving it a quirt of WD40 every couple of years.

In the last couple of months it was a bit tricky to open - had to
pull/push key in/out slightly until it would turn.

Today it would not turn at all - key goes in, and nothing more. I tried
the other two keys we have, but still nothing.

Not too bothered about replacing it, but Before I get hold of the
neighbour's bolt cutters, is there anything else I can try?

Get someone to hold something heavy under it then tap it many times with
a small hammer, changing the orientation every so often.
