Spoilers...
Oooops.... cool down. The police didn't try to blow up the door of the house for five days. They spent the first three days looking for the guy who had the keys. During the 4th day (if I'm not mistaken) they found the corpse of the guy who had the keys. Only in the 5th day they tried to enter the house by force. So, the police really took only a few hours trying to breach the house.
Satisfied?
