FORD 2011 Explorer v.3 - Manual (Page 156)

After locking the doors using any of the methods above, the turn signal
lamps will flash once indicating that the perimeter alarm is in the
pre-armed mode and will become fully armed in 20 seconds.
When fully armed (after the 20 second pre-arm mode), any IA keys (if
equipped) found inside the vehicle are disabled/inoperable and will not
start the engine. Press
button to re-enable them.
Disarming the system
To disarm the system, do any of the following:
• Pressing the power door unlock control within the 20-second,
pre-armed mode will disarm the system.
• Unlock the doors by pressing unlock
on the remote entry
transmitter.
• Unlock the doors by using your keyless entry pad.
• Enter the vehicle using intelligent access (if equipped).
• Turn the ignition on with a valid key (if equipped with IKT only).
• Press the panic control
on the remote entry transmitter. The alarm
system will still be armed, but this shuts off the horn and turn lamps
when the alarm is sounding.
• Unlock the doors using a key. If you use this method the system will
not disarm, but you will have an opportunity to disarm the vehicle
once entered. See the Note following.
Note: If the driver’s door is unlocked with a key, a chime will sound
when you open the door and the message center will display TO STOP
ALARM START VEHICLE. When this occurs, you will have 12 seconds
to disarm the alarm using any of the actions above, otherwise the alarm
will trigger.
Perimeter alarm issues
If there seems to be a potential perimeter alarm system problem with
your vehicle, ensure ALL keys/remote entry transmitters are brought to
your authorized dealer to aid in troubleshooting.
