OEM remote range during RS operation is drastically low

Question

KIA Sedona 2016 Evo One with 3xlock start with OEM key fob

Evo One causes some RF interference in the system for OEM key fobs when RS is operating.  I can start the car from a distance of probably 300 feet, but if i want to shut it of, it does not deliver the signal unless I come at least 30 feet to the car.  Any Idea what option in EVO One can cause such an interference?

Answer 1

The EVOONE is not causing any interference, the vehicle is creating interference when engine is running.
