How do I lock my 2017 F250 truck without setting the alarm?

 

Push the door lock button on the door only once when getting out. I only think that because if you push it twice then when the door closes the lights flash like when you use the key fob. And if I only hit lock on the key fob once the horn doesn't honk. Dont know if that means the alarm isn't on but I would assume so.

 

This is from my owner's manual for my 2016 Expy. I believe electronic locking to be with the keypad on the door or with the fob. One press of either locking method arms the alarm. Verified with my service department as well. Salesman said you need to press LOCK twice to arm the alarm. Incorrect:

ANTI-THEFT ALARM
The system will warn you of an
unauthorized entry to your vehicle. It will
be triggered if any door, the luggage
compartment or the hood is opened
without using the key, remote control or
keyless entry keypad.
The direction indicators will flash and the
horn will sound if unauthorized entry is
attempted while the alarm is armed.
Take all remote controls to an authorized
dealer if there is any potential alarm
problem with your vehicle.
Arming the Alarm
The alarm is ready to arm when there is
not a key in your vehicle. Electronically lock
your vehicle to arm the alarm.
Disarming the Alarm
Disarm the alarm by any of the following
actions:
• Unlock the doors or luggage
compartment with the remote control
or keyless entry keypad.
• Switch your vehicle on or start your
vehicle.
• Use a key in the driver door to unlock
your vehicle, then switch your vehicle
on within 12 seconds.
Note: Pressing the panic button on the
remote control will stop the horn and signal
indicators, but will not disarm the system.
