2017 ram 2500 problems (go figure)

I had a bad alternator that ended up causing my batteries to die completely. I had a mechanic come out to fix it. The batteries didn’t hold a charge the next morning and my key got stuck in the ignition when I tried to turn it over. I replaced the batteries and the key is still stuck. Does anyone know how to solve my issue or should I just continue to bend over for the Chrysler gods?
