NO KEY DETECTED Message (enhanced, if equipped)

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: To determine if vehicle is equipped with the enhanced No Key Detected and Automatic Engine Idle Shutdown features, access Message Center>Settings>Vehicle using the message center controls. If "Auto Engine Off" is listed in settings, the vehicle is equipped with the enhanced No Key Detected and Automatic Engine Idle Shutdown features.
NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS  no-start if the IA  key is within close proximity of the charger. If a concern is observed, move the IA  key away from the charger and attempt to start the vehicle.

There are 2 scenarios in which the No Key Detected message displays in the message center.

The first is when the ignition is off, the START/STOP button is pressed and a programmed Intelligent Access (IA) key is not detected inside the vehicle. If a component failure (such as a dead Intelligent Access (IA) key battery) is causing the No Key Detected message to display, the backup starting method can be used.

The second scenario is when the vehicle is running, the driver exits the vehicle with the programmed Intelligent Access (IA) key and closes the door.

The RFA  module activates all 3 passive start antennas to search the inside of the vehicle for an Intelligent Access (IA) key any time a door or the luggage compartment lid is opened and then closed with the vehicle running. The Key outside car message displays in the message center and the horn chirps twice when the ignition is on and an Intelligent Access (IA) key is no longer detected inside the vehicle.

This strategy deters the Intelligent Access (IA) key from being separated from an already running vehicle. If the Intelligent Access (IA) key is no longer in the vehicle, the ignition remains on and the vehicle continues to operate. When the START/STOP button is pressed to turn the ignition off, the ignition can be restarted without an Intelligent Access (IA) key present inside the vehicle for approximately 10 seconds. After 10 seconds have elapsed, a programmed Intelligent Access (IA) key must be present to transition the ignition out of off. If the driver door is opened during the 10-second countdown, a programmed Intelligent Access (IA) key is needed to transition the ignition out of off.
