Hi guys

On driver's side, unlock sensor on door handles are not working most of the time, and some hot days rear driver's side works.
and sometimes when I walk up to the vehicle, it unlocks itself (when driver's side rear handle works)

I am thinking it might be antenna issues, since passenger sides work every time.

I did some researches, and ppl say door handle sensors go bad all the time, but even auto unlock when I walk up to the vehicle does work on and off... I am thinking I should start from antenna....

Any thoughts ?

Thank you in advance~!
