    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).

    My 07 SKS car right now. I have the remote in my pocket. I walk up to my 07, extend my fingers to touch the rear of the door handle. My hand or fingers have physically touched the handle; only then do I hear the audible click clunk, and then only then do I have to lift the handle. I'm doing this right now in 15°C weather in front of my house.

    Jesus Christ my hand did not touch the door handle until after the clunk and click I have to pull on the handle to open the door not for it to unlock.the sensor don't need touch apparently I guess my finger breaks the circuit ? I don't know . Same at trunk I just stand by the trunk hear the click clunk . Then I have to touch the rubber and lift . I'm standing at the car now . With two buddies of mine they have same car too
