key fobs only work when the button is pressed so I suspect that the switch may be faulty and is stuck in the pressed position

1. Get in your vehicle.
2. Close the door.
3. Put key in ignition
4. Do not turn on the ignition yet.
5. Hold down on the unlock button on the door panel. Do not let up.
6. Turn the key to ON, OFF, ON, OFF (while still holding the unlock button on the door panel).
7. Release the unlock button.
8. The door locks should cycle, indicating that you did everything correctly.
9. Have all your remote entry fobs available. Hold down on both the lock and unlock buttons until the door locks cycle. Do the same on all key fobs. This will re-program all of them.
10. Turn ON the ignition key to exit the program mode.
11. DONE.

You should not have to reset the key fob after a battery replacement. The signal from the key fob stays the same and is programed to the reciever.
If the key fob needs to be reprogrammed then follow these steps.
1. Have all key fobs with you during programming.
2. Sit in the vehicle with all doors closed.
3. Lock all doors using the Lock/Unlock switch on the door.
4. Insert and withdraw the ignition key 7 to 9 times within 10 seconds (do not turn the key, just insert and withdraw).
5. The 4 way flasher indicator on the dash should flash once or twice.
6. Insert the ignition key and turn it on (key on, engine off).
7. Press any button on one remote and the 4 way flasher indicator on the dash should flash once.
8. If you have more key fobs to program use the Lock/Unlock button on the door to unlock the doors and then lock the doors.
9. Press any button on the next key fob and the 4 way flasher indicator on the dash should flash once.
10. Repeat if you have more key fobs. Only 5 can be programmed.
11. To exit, simply turn of the igniton and remove the ignition key.
12. Unlock the doors using the Lock/Unlock switch on the door and exit the vehicle.
13. Make sure the window is down when testing remotes in case you leave the keys inside.
14. Close all doors and test all remotes that were programmed.

Do not skip any steps or the process will not work.

If the 4 way flasher indicator does not work when inserting the key, you will need to start the process from the begining. If it still does not work the receiver may be your problem.

If the 4 way flasher indicator does not flash when pressing any button on the key fob then the key fob is the problem (dead battery or defective remote)

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.
