Writing this as of 10am, noticed issue at 4:40am, last drove 5:10pm of the day previous. Key fob won't lock or unlock the doors. Headlights and dome lights work fine. Mileage indicator appears when the door is opened. Start button has no function; no LED indicator present even when confronted with key fob (both used and spare). Battery attempted to jump and charge, no indication of difference when applied. Has been charging since 8:30am.
