Lost Car key at Orleans Casino

So, not sure if this is the place to write about this and get some feedback on what to do but here we go:

I left my car key while I was gambling, I was a little under the influence and it was an honest mistake, I left the vehicle home and drove up with some friends so the car is not on property. I came back the next day after I called and they confirmed they had the key, I asked if there is anything they needed from me and they said no, so I uber up there to go get the key and then they tell me that because the car is on property I need to verify ownership, which doesn't make sense because regardless if I verify ownership how would you know that key goes to that car I'm providing paperwork for? This car is my managers car, and hes been letting me borrow it. I have a notarized letter which has been signed by both me and him verifying that I am in fact in possession of the vehicle. I send this over to them, and they tell me to come in tomorrow (today now), I bring in all of the paperwork and now they are telling me because the car is not on the property they can not verify that the key goes to that car.

So here's where we are at, I can't bring the car down here because I don't have the key, I can't get the key because the car is down here, so now they are putting me through this never ending loop and basically saying there is no way for me to get the key back, this is the only key to the vehicle, my boss is out of town and currently has no service to reach out to, and the vehicle now has a tow sticker on it because my HOA believes it has been abandoned since it hasn't been moved in some time. I'm now going to have to worry about it getting towed, I won't be able to get it from the tow yard because my boss is the owner and is out of town so its going to rack up fees, and by the time I get a replacement key the car will be towed. I have no way to get this vehicle to the casino, so what can I do now? I've reached out to every body in the security department and everyone just seems clueless on how to help me. I have never gone through such a terrible system, if I lost a house key, would they expect me to bring the house to the casino for them to verify that it goes to that house? Or if it was for an offroading vehicle? It doesn't make sense, and I'm completely out of options on what to do.
