Poor Operating Range Performance

If extremely poor operating range is experienced:

  1. Do not change transmitter batteries. Range is not affected as the battery ages.
  2. Do not replace or reprogram transmitters. Range performance is determined primarily by the receiver control module.
  3. If range performance exceeds about 30 feet (10m), do not replace the fob or module. This is within design limits.
  4. If range is consistently less than 10 feet (3m) from the center of the vehicle, the system can be considered "compromised" provided the following factors are first ruled out:
    • Verify external antenna is connected (if equipped - e.g. Focus and Freestar).
    • Ensure issue exists all the time versus just in specific locations. Such as by local grocery store, radio stations, TV transmitting towers or by buildings with power generators.
    • Ensure no other aftermarket or dealer installed systems are on vehicle when troubleshooting. (Examples: other RKE, remote start, perimeter alarm systems, etc.)
    • Ensure issue is consistent in nature and not just from one approaching angle from/to the vehicle.
