> If they refuse to give the data you have a warrant for they broke the law.
Warrants aren't issued for data, they're issued for property. A warrant authorizes law enforcement to search for and/or seize evidence (i.e. physical property) without regard for the owner's property rights. The owner doesn't have to give them anything or aid the search in any way beyond simply not interfering. Standing back and leaving them to break into the safe on their own does not violate any law. You might open it anyway just to show goodwill and avoid damage to the safe, but there is no obligation to do so, and unnecessarily demonstrating that you have the ability to open the safe may, in certain situations, amount to testifying against yourself.
