Question about Vehicle Parts & Accessories
Frequently, but not always the car will not start after being turned off and locked. the inside lights, headlights and dash lights come on, but will not start. we have tried unlocking with key and only locking it with keyless remote. we have been unable to connect the dots. the alarm light blinks when opening the door, but does not go out after locking the door. is there a way to disable it

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

The Alarm on my Mercedes ML320 sounded every night, then it started doing it more often, Showed it to the dealer he says it's the 'Tow Sensor', that needs to be repaced. $700, down the drain. I have already started hating this car, it eats $500-600, every 6 months...

the door lock actuator is defective, they get really hard to move when they go bad, that is why the difficulty with the key.
