Resuscitation alert.
The "new" multi-door ('23 Charger, aka Crew Cat) didn't start today. I wasn't surprised and had already asked the dealer to put a new battery in it before shipping it. Well, that didn't happen.
It'd been on a solar charger for about 12 hours before today's starting attempt, but that apparently wasn't anywhere near enough, surprise, surprise.
Okay, so I put a good battery in it - happens to be the same 94R as in a 1500 - and...still no cranking. Hmm. Wonder if it's a bad fob. Tried the other red fob, no difference. Tried the black one, resulting in success.
But, the red fobs will lock and unlock it.
My girlfriend's been communicating with the dealer, initially about the abused battery, then about only one fob working (this is in real time as I'm writing this).
Turns out there's a chip on the key ring that must accompany the key in use, which happened to be the black one. That's good news. Now it remains to see if the nearest dealer will accept her showing up with the original bad battery and get a new one...without bringing the car.
I'd never heard of anything like this chip, but if someone else runs into this issue, here's the solution. You can't leave home without it.
