If you have the door panel off you can manually unlock with the lever on the door actuator. Find my actuator repair thread, I show exactly how the double lock works. You can keep

If it's double locked you would lock the car from outside or with the key fob to sync double lock, than while the doors are double locked and sitting inside, press and hold the central lock button and pull the inside door handle to unlock the actuator.

Pull again to open the door. (warning will trip the alarm). Reset alarm with key in the ignition turn to accessory.

When locking from inside either use the key through the driver window rolled down or the key fob but lock it twice to defeat the motion sensor.
