Diagnostic Overview

A "No Key Found" Message Is Displayed in the Message Center

Normal Operations and Fault Conditions

During each vehicle start sequence, if the RFA (Remote Function Actuator) module does not detect a programmed IA (Intelligent Access) key is inside the vehicle and the PATS (Passive Anti-Theft System) transceiver does not receive a programmed IA (Intelligent Access) key identification code, the message center displays the message Key not detected.

NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS (Passive Anti-Theft System) no-start if the IA (Intelligent Access) key is within close proximity of the charger. If a concern is observed, move the IA (Intelligent Access) key away from the charger and attempt to start the vehicle.
