Had something very similar, everything would come on, then the minute you turn the key, boom. All shuts down, cycling back door lock, etc. And like everyone else above, battery. Mine wasn't brand new, but still under warranty, so that was nice. But it was a bad battery, about a year old. Happens all the time on these Lib's, that's why they responded so quickly, lol. Freaky weird, but search for it on here. Hope it's just a bad battery and you don't have to hunt for a bad connection. Good luck!
