Nissan door lock and unlock system working?

Here is how the system is supposed to operate:

  • The lock and unlock switch on driver's door trim can lock and unlock all doors.
  • With the lock knob on front LH or RH door set to LOCKED, all doors are locked.
  • With the door key inserted in the key cylinder on front LH or RH door, turning it to LOCK, will lock all doors; turning it to UNLOCK once unlocks the corresponding door; turning it to UNLOCK again within 5 seconds after the first unlock operation unlocks all of the other doors.

However, if the ignition key is in the ignition key cylinder and one or more of the front doors are open, setting the lock and unlock switch, lock knob, or the door key to LOCK locks the doors once but then immediately unlocks them. (KEY REMINDER DOOR SYSTEM) If any of the following symptoms occur, key reminder door system is malfunctioning.

  • With ignition key removed from the ignition key cylinder and all doors closed, operating the lock and unlock switch or lock knob on the front LH or RH door trim unlocks all doors the instant they are locked.
  • With ignition key inserted into the ignition key cylinder and front LH or RH door opened, operating the lock and unlock switch or lock knob on the front LH or RH door trim to LOCK does not unlock all doors.

---------------------------
The default operation is that it unlocks when you remove the key from the ignition for traditional key ignition models (NOT when you turn it off).

Intelligent key models unlock when the engine is shut off (default mode).

Lockout protection

When the power door lock switch (drive's or
front passenger’s side) is moved to the lock
position with the key in the ignition and any door
open, all doors will lock and then unlock automatically.
This helps to prevent the keys from
being accidently locked inside the vehicle.

1) All doors will be locked automatically when
the vehicle speed reaches 15 MPH
