I have a 2001 nissian sentra and I have to start my car by unlocking it with the remote! Now the remote is not letting me unlock my car; I checked the remote and it is good! When I tried using the power switch it does not let allow to use any buttons! I have to manual lock my car either way my car won't start! Help?

SOURCE: Car Alarm

sounds like the drivers side key switch has failed remove the interior door panel and there will be a switch attached to the back of the key lock cylinder or around there it should be two or three wires also check the door jamb wire harness where the door closes for any broken or damaged wires, use a vot meter and see if you get power or ground to the opposite side of the switch when you use the key to lock and unlock the door if nothing changes and there is power or ground! at this switch i would replace it, i don't think there is one but if the car has a passenger side key hole try to unlock the car from that side and see if you get the same problem -jeff

Im no professional but i did recently buy a 93 maxima and i have the same security alarm problem and my powered locks dont work at all. im taking off the door panel today to take a look and see if the alarm sensor is loose or damaged, if it is, ill probably just disconnect it. one thing i have noticed though is that when i hit the lock or unlock button, i hear a faint click from the dashboard area which im assuming is the solenoid on a transistor which would mean that the buttons work but the transistor isnt delivering power. Semi-Solution for Locks: Listen for very quiet click when you lock/unlock doors, if you hear it, uve got major work to do, if you dont, then take apart the door and check the switch connections. Semi-Solution for Alarm: take off the door panel and disconnect the sensor.
