Meaning permission is given by the aircraft to unlatch the door, and having the door is possible?
No. There is no automatic system for locking doors. That would be a potential safety hazard in emergency evacuation situations. In the event the system failed and prevented a door from opening, pax could be trapped in a fire or water landing situation. Except for the 767, all doors are manually operated.
Most vehicles have power door locks.. Some even have child safety door lock features..
For myself, it would be unbelievable if airplanes didn't have power door locks,...
Comparing automobile and aircraft doors is like comparing apples and oranges.
with safety mechanisms preventing doors to be open on flight..
They do. Its called the laws of physics in the form of air pressure.
