For the heck of it, disconnect the battery ground (black) in trunk overnight. Attach in the AM and try again.
NOTE: there will be no power so remote will not open doors or trunk in the AM. So... Lock your doors, open the trunk, disconnect battery, shut trunk, use key to open front door in the AM, reach in and unlock the rear door, reach through rear seat pass through and open the trunk with the emergency release, attach battery, back to normal.
