4x4 crew cab, FOBs good but will not lock or unlock doors from outside of truck?

I answered this yesterday, but you must have done it as an 'Anonymous' posting. I told you exactly how to fix it short term and long term.

It sounds like the linkage rods between the lock actuator and the door lock has come off. You'll have to remove the door panels (not going to be easy when the door won't open) but it can be done. Locate the rod on each door and pop it back into place. You may find a diagram on line, but you'll need to search for it.
Good luck...

with both fobs?, one at at time.
try them both, and with fresh batteries inside.
are you indside car, outside, car, or key in ignition, or running engine?
what are the conditions.

You need a new door lock actuator.

So , the power door locks won't lock or unlock with switches inside the vehicle or with the keyless entry remote fob.??? Is this correct ????
Do you know what a BCM - body control module is ? Do you know what diagnostic trouble codes are ? If not your best bet would be to take your vehicle to a GM dealer or someother qualified repair shop.
DTC B3142 or B3143
The body control module (BCM) provides an output to the driver switch assembly through the door unlock control circuit for controlling automatic door unlock, anti-lockout, and keyless entry unlock functions.
DTC B3152 or B3153
It could be the driver door master switch , could have broken wires inside the rubber boot from the body to the door . Do the power windows work ?
The keyless entry system has the following main components:
• The transmitters
• The body control module (BCM)
When you press a button on a transmitter, the transmitter sends a signal to the BCM. The BCM interprets the signal and activates the requested function.

How did you do this ,,checked and made sure locks and remote programmed,they were,but still do not work ?????

Need a scan tool to program
Important: All key fobs must be programmed each time any one fob is programmed. The scan tool must stay connected until all of the transmitters are programmed.
Install a scan tool and navigate to the BCM Module Setup menu.
Select Program Key Fobs.
Follow the scan tool on-screen directions.
When the programming operations have completed, operate the transmitter functions to verify correct system operation.

Lock linkage needs lubrication inside the door or check the lock selenoid or switch.

this is posted in your owners man. i think you need to pull the high beem switch back and then hit the door locks once for on and twice for off depends, i have a crew cab so they have more door unlock lock choices

Make sure the meter is connected to body ground instead of door ground. Does it neither lock or unlock? You will only see power when the switch is operated. All locks operate from a common fuse. Check for wire pinch at the door hinge area.

Transmitter Programming Procedure
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on the transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of the transmitter.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation.
Good luck

Your dash switch has gone bad. Normally that is a warranty fix. Good luck!
