My 07 nissan armada is keeping me locked out of the back. the problem appears to be in the door lock actuator for the rear lift gate. this vehicle is only equipped with keyless entry system (you cannot unlock/open the rear gate with the key because there is no key hole). the problem manifested slowly, over time missing only occasionally on the unlock/engage handle for the rear door. now it does not unlock at all. it appears that almost all armadas are having this system failure. the safety danger implications are enourmous in this case as this is an eight passenger vehicle with the potential to trap passengers in the rear bench area with no way out in an emergency (there is no way to open the rear door from the inside either). *tr
