Travelvan is right, the key not releasing is because something is shorted, draining voltage. There is a mechanical over ride to get the key out. Look up at it under the steering column, and you should see a molded in hole with a black plastic tab sticking out of it. Pull that, and your key will release. Disconnect the main battery, and your key will also release I believ
My 2021 with 600 miles on it had a dead battery after not driving for a while last winter. I borrowed a battery charger and kept it on overnight to charge it. I ended up getting dcdc combo unit that trickle charges off the lithium battery bank because I just don't drive it much in the winter.This thread is helpful because I just unlocked my van to show friends in town and had the same thing happen. Not having driven it in a few weeks the battery was dead. Definitely going to install a switched trickle charger off my shore power, but for a 2018 with 21K miles, is this about the time I should replace OEM battery anyway?
I've already got one car with a parasitic I've been chasing for three years, I'm hoping this isn't another - that and the oil (cooler?) leak... I left Ford hoping Ram would be at least a little more reliable!
