i would say the theft module saw the door trying to be open without the door lock or fob first, once the door lock button was pushed it shut down, it new doors were trying to be unlocked in a theft manner, once shut down it needs time to reset or needs to see ignition cycle with key and read chip in key, smart system isnt it, good luck.

Testimonial: "I thought it was something like that, so I guess using the car door wedge set this into motion and the guy with the keys inside the vehicle is screwed"
A solenoid operates the lock mechanism. Does it make a 'click' when the switch is operated? If so, then the linkage connecting the solenoid core to the lock has probably come undone. If no click, then the solenoid itself may be defective or the wiring to it is broken or disconnected at some point. Either way, the inside door panel must be removed to access. Hope this helps!

SOURCE: the power door locks stopped
Sounds like body computer is malfunctioning or the module that controls the door locks lost it's program.Disconnect the battery for few minutes then reconnect and check.In some cases this resets the system computer and all starts working.But if that does not helps then problem has to be checked with the power door lock system.Either a power door lock actuator or the power door lock switch.
Usually the most common problems with power door locks are the actuators. They are small electric motors used to lock and unlock the car doors when activated by a switch or remote. Like any electric motor sooner or later it will fail. Replacing an actuator involves removing the interior door panel for access. Some are part of the door latch and some are independent.
Either way, door lock actuators need to be replaced if they are buzzing, working only in one mode or are not working at all. if the problem is with the door lock actuator or just the switch. If a All the door locks, only work when locking and NONE of them work to unlock, then the switch is most likely the cause.

sound like you might have a few problem interior light might be the door switch but the lock n unlock can be a fuse if they dont work in the truck or need to chance the battery in your remote
