2021 FORD F-550 lights

When you lock your vehicle using the
power door lock control (with the door
open, vehicle in park and ignition off), your
vehicle searches for an intelligent access
key in the passenger compartment after
you close the door. If your vehicle finds a
key, all of the doors immediately unlock.
In order to override the smart unlock
feature and intentionally lock the
intelligent access key inside your vehicle,
you can lock your vehicle after all doors
are closed by using the keyless entry
keypad, pressing the lock button on
another intelligent access key or touching
the locking area on the handle with another
intelligent access key in your hand.
When you open one of the front doors and
lock your vehicle using the power door lock
control, all doors lock then unlock if the
ignition is on.

• Your vehicle reaches a speed greater
