I've got a cheapish (Master) rubberized lock on an outside gate that

What's the best approach, whack it with a hammer?

Flood it as much as you can with WD-40, tap on the corners with a hammer, or
wherever there is metal to tap on, wait a few hours, repeat, and try to
unlock. Chanced are it'll come open.

Or ... bolt cutters.
