Hyundai and KIA Motors have been using the smart key system on many models for many years already and one of the important parts are LF Antenna (Low Frequency Antenna) which are designed to detected the Fob key in any different areas inside or outside of the car. There might be between 5 to 8 LF Antennas in different models, so in this video I show you how to check all these antennas using a scan tool.

Damn it. I think my bumper antenna is bad. I can't replace that myself. I have a 2017 hyundai avante/elantra.. Any idea what the service center will charge?

Hi there, how do you know that rear bumper antenna is faulty?
Replacement is very quick so for an experienced guy will be just like a piece of a 🎂. But you need to make sure that there is an antenna inside the rear bumper as I’ve seen some aftermarket smart key without that antenna.
