No power, will not start, and electric key stuck in ignition

I have a 2012 dodge grand caravan. I tr ied using the electric key to unlock and it wouldnt work. So i used the real key to unlock the door. I tried to use the buttons on the drivers door to unlock door for my son and it wouldnt work. I reached over and opened his door for him. I put the electric key in to start and nothing. No lights will come on and now the key is stuck in the ignition. My van was working fine yesterday.
