Small pry bar, or heavy duty screwdriver may prise the case apart, as long as you don't mind buying a new case. Aim half way between the locks and then slide your tool towards the locks. I know it's destructive, but if you're after a quick fix without learning to pick, it's an option.
And thermite is probably not an option in this case (hah pun as well )
(got away with a mention of Therm*** twice in one day, that should reset the datum !)

It's all about the tension . . .
