If hotel security forced their way into my room in any property I stay at at I'd be checking out immediately and would be doing a credit card charge back on any charges.
For instance - while moving from Arkansas to Virginia in 2013, I had a rifle with me in the U-Haul, and didn't want to leave it in the vehicle for it to be stolen. I just slung it barrel-down over my shoulder and carried it with all of my family's bags to the room, right past the front desk. It was a folding AK variant, which I chose for the trip because it was easy to keep accessible behind the seats' headrests, so if they were going to have an issue with a rifle that would probably be the one.
Not only is this sort of thing fairly typical in many places, in some (most?) states a hotel room is considered a domicile, and it's illegal to ban firearms as a condition of renting the room.
How do you perform a credit card charge back yourself?
If they refuse or don't reply you call your credit card company and tell them you dispute the charges; they usually immediately refund you and take it up with the hotel.
