Description And Operation: Description: Antennas

WARNING: This page is about a different car, the 2015 Kia Forte5, 2015 Kia Forte Koup, and 2015 Kia Forte. However, it is still accessible from the selected car via links, so may be relevant.
  1. Emitting LF Antennas:

    Inductive antennas in and at the vehicle are used to transform the current, driven by the SMK ECU antenna driver, into a 134.2 kHz magnetic field, which is the carrier for the SMART KEY challenge.

    Three antennas cover the vehicle's exterior: two antennas in the Door Handles (DS and PS) cover the area around the doors; one antenna in the rear bumper covers the area around the trunk.

    Up to two antennas cover the vehicle's interior and the trunk interior: one in the passenger compartment and one in the trunk.

  2. Bi-directional Immobilizer Antenna (for Limp Home):

    The Immobilizer Backup Antenna is used for sending and receiving data: it emits a magnetic field (134.2 kHz challenge) and receives changes in the field strength (response of Transponder).
