    Weird issue, my keyless entry was working on my trunk (as in car is locked, I walk up to it and put my hand on the latch and it unlocks/opens).

    Lately that is no longer the case.

    I have techstream and verified that the antenna or oscillator picks up the key for both the interior and exterior rear hatch sensors (as in ran the test and heard a beep when i took the key back there).

    The trunk opens when I unlock the car, so to me it isn't the latch either.

    Any advice on what could be wrong? Is there some part I'm missing between whatever makes the car beep when I run the active test and the actual handle?

    It isn't the key fob either because I tried with both key fobs and got the same results.

    But when you walk up to the driver side door locked and reach your hand out it unlocks and you can get in the car and start the car without ever looking at the remote or touching it? You have factory manual steps ?

    You have to do more than reach your hand out; you have to touch the back of the door handle to unlock the door(s).
