Smart Key Reminder 1

WARNING: This page is about a different car, the 2016 Hyundai Elantra GT and 2015 Hyundai Elantra GT. However, it is still accessible from the selected car via links, so may be relevant.
  1. Preconditions:

    All terminals OFF & at least one door open & locking status is not locked checked by SMK periodically every 100ms, as long as CAN/LIN active.

  2. Event:

    At least 1 door knob status changed from unlock to lock.

  3. SMK actions:
    1. IF NO FOB-IN ACTIVE

      SMK performs a search for the fobs in the interior of the vehicle. The same LF-strategy has to be used as it is defined for the ID out warning (registering only, no authentication).

    2. IF FOB-IN ACTIVE

      SMK searches valid TP

    If no fob or no TP has been found, no action is required.

    If any valid fob or valid TP has been found, SMK unlocks the vehicle by sending a CAN Key Reminder unlock message with the fob number.

    If any valid fob has been found, SMK unlocks the vehicle by sending a CAN/LIN Key Reminder unlock message with the fob number.
