Well the doors won't lock and set the alarm. But there is a solution. Whatever door doesn't lock, there is a place to insert key and press a white manual tabbed lever to do yourself. Then close the door and press lock on keyless entry remote and presto. Alarm set. Its a temporary fix but the sensor needs replacing. I only have to do it once in a while. Also my passenger door won't unlock when I press it, so I have to open through front. Its fine but actually it is cheap to fix. Just had no time to replace bad sensors.
