Remove the safe fro its current location, this may require several strong men and a few beers/heavy machinery/an army of helper monkeys.
Once removed and loaded onto your transport, I suggest a mini/VW Beetle/unicycle. You may think the weight of the safe may be too much forthese forms of transport but remember your trips to the circus when 16 clowns got out of one car, the same applies here the safe disapears through a spacial rift and reapears when comanded.
Locate a building site, soething near the city is best as it will most likely have the require equipment. Pick a nice spot when you arrive, Piant a white cross on the ground, it will be night of course otherwise you won't be able to get into the site unchallenged hence the white cross will help you locate the safe. In the middle of this cross place your locked safe. Now find the pile driver and start hammering at that metal box
