But you mentioned that your trunk button works after you push any other request button first. It shouldn't matter because the car will detect the presence of your card everytime you push any request button and it won't respond if it doesn't see your card. So when your trunk button works, the car is picking up ID from your keycard somehow. The question is why wouldn't it detect your card the first time.The only thing I've done recently is install a bluetooth cell phone kit. It's under the dash on the driver side and connects to the fuse box for power. Unless I loosened something by accident while I did that. I would have to see a wiring diagram of the advanced keyless system to know if I even got anywhere near there.
Yeah, but once the request switch is pressed, it uses the proximity sensor to find the keycard. If the sensor is not working, it can't find the key card.
The reason why I asked you about your doors being closed or not before is that one time my trunk sensor was frozen from carwash, I thought it was the button first then I realized that the button worked when I had the trunk opened. It was probably one of the other non-frozen sensors picking up the signal without the trunk blocking it.
May be you should remove your bluetooth kit. Pretend that you haven't touched any wiring and let the dealer fix it.
