Bolt cutters will probably cut through the cabinet door or side if you can find a spot to get them started and you have a lot of time.
Otoh, maybe you've got a cabinet in a DC with very secure locks from europe.... But all are keyed alike. Whoops.
A drill would be easier to bring in (especially if it just looks like a power screwdriver) and probably get in faster though. Drill around the locks/hinges until the door wiggles off.
I'd go with a drill -- but I'm not sure what possible threat vector would have access to the cabinet who would be able to get to the cabinet in any decent data center.
