I have a 2009 BMW X5 E70. Today I backed the car out of the garage, washed and dried the exterior, then pulled the car back into the garage to vacuum it. When trying to vacuum, I wanted to move the seat forward some, so from the passanger side I pressed the power button to put the car in acc mode to be able to move the seats. I pressed the button and the lights went back off. I tried again and same thing. I then put the actual key fob into the ignition to try that (I have comfort access). The interior lights still did the same thing, came off and on. It was a funky thing, some lights on the A/C would come on and some on the cluster gauge. I saw a gear symbol with an exclamation mark on it on the dash as well. Had never seen that. I try starting again and nothing.

Now the light on the hazard light button in the middle of the dash is doing a constant flickering. I tried pressing it and it did nothing and I am still unable to get the key out or start the car. The whole car is completely locked up. I crawled through to the trunk and used the emergency escape to open the rear hatch and disconnected the battery. I left it dc'd for about 15 min then hooked it back up. The flickering on the hazard light button continued and nothing else is working. I also tried manually releasing the parking break to see if that would do anything and it did not (I never set it in the first place, but worth a try). Does anyone have any ideas for me? I'm completely at a lost and now stuck at home and unable to make it to the families for Thanksgiving :/ I also linked a video from my dropbox to see the flickering I'm talking about.
