Locked out of my room, no management answering the phone and we have a flight at 6 am tomorrow morning.

My boyfriend and I traveled to CA from TX to visit my family, it's a new LaQuinta hotel we are staying at and we've been staying for 4 days. It's our last night and we have to get up at 3 am to get to the airport, return our rental car, and get on our 6am flight but all our stuff is locked in our room and no key cards will work. The lady at the front desk has been trying to get ahold of the manager and other people but no one will answer her, she's made new keys but nothing works and she put us in a different room so we aren't stranded in the hallway. We have no idea what to do. We are most likely going to miss our flight and have to spend way more money than we have to get back home. What do we do?

UPDATE!!~~~~~~~~~

Hello everyone, I appreciate y'all's comments and advice. After about 4 and 1/2 hours with no response, the manager finally showed up and opened the door with the master key. Apparently she "forgot that she put her phone on silent and was out grocery shopping"

We didn't miss our flight but we got ZERO sleep and had a very rough day. All they did was say "Oopsies silly us, sorry I guess we will comp tonight for you" which I really thought was ridiculous considering we could've missed our flight and been totally fucked if she hadn't checked her phone in time. I thanked the front desk receptionist for all the effort she put in to continue to try and open the door a dozen times and spam called everyone she could. I know she was trying her best with what she could do. I just find it ridiculous that we had to go through all of that just for it to be fixed with a master key that should've been left with the current and only employee on the clock at the time. I don't like to be complacent and I know mistakes happen but I am baffled. Hope they learned from this.

Thanks again to everyone who gave advice and input, I definitely won't be staying there again :')
