Procedure For Updating Secret Key Data

  1. Connect scan tool to Data Link Connector (DLC). DLC is located under left side of instrument panel.
  2. Go to ENGINE and then MISC menus on scan tool. Place the SKIM in SECURED ACCESS MODE by using the appropriate Personal Identification Number (PIN) for this vehicle. PIN may be obtained from the owner, vehicle's invoice, or from the manufacturer. Select UPDATE THE SECRET KEY DATA. The data will be transferred from Smart Key Immobilizer Module (SKIM) to the PCM, allowing the vehicle to start.
    NOTE: On Ram Van and Ram Wagon, if 3 attempts are made to enter the SECURED ACCESS MODE using the incorrect Personal Identification Number (PIN), the SECURED ACCESS MODE will be locked out for one hour. To exit this locked out mode, leave ignition switch in the ON position for one hour with all accessories turned off. It may be necessary to monitor battery state and connect a battery charger if necessary.
