Must you stand close to the car for ANY of the IR sensors to work? If it is specific ones, chances are the reciever is not functioning as it should and the solution is to buy a new on. That happened on my trunk sensor. Unless I was in the garage out of the sun or very close to it outside it wouldn't work. swapped the trunk and door sensor to check and yup, needed a new trunk sensor.That is correct. You can still use the key to manually operate the locks, trunk, and start the car. I’m getting close to that point with mine. Buttons only work when I’m standing next to the car.

And I noticed the other day my PS door sensor doesn't work, so I'll need to get a replacement one of these days.
