I have a 2000 chevy silverado z71. my clicker (key fob) only locks and unlocks passenger side door. Also when my driver door is opened the security light flashes in the message center and my door dinger wont stop (thats with the key out btw) unless i put my key in and turn to run position. I bought a new door lock actuator and that didn't fix the problem with the clicker. my button on my door panel dont even lock the door either. has to be done manually. Any help would be appreciated.

Maybe the door switch.

That sounds ugly, could be an issue with the BCM(body control module) as it controls the alarm, locks etc...Did you change the battery, or jump-start a vehicle or anything recently to the vehicle?

I have a 2008 Silverado crew cab. My keyless lock will not lock the driver door. It does lock and unlock all the other doors. I have to manually lock the driver door. When I go to unlock it, I must first unlock the other doors with the keyless then unlock the driver door manually. If I don't, the car starts honking. This just started all of a sudden one day. Like the person who started the message, any idea what would be causing this? Linda

Sounds like an inoperative drivers door lock actuator, if it doesn't lock or unlock, even if you use the door switch,that's more than likely the culprit

Check voltage at actuator while locking / unlocking with remote. If the actuator is getting the " correct and not less " voltage then should be actuator.

Just another dead thread we don't have to worry about...
