Spray some lubricant (wd40 etc.) Into the lock mechanism on the doors. The switch may be jamming up. Let me know
The front door entry system contains a latch that is fastened to the inside of the door frame and is controlled by the exterior and interior door handles. The latch contains a door ajar switch and a door lock actuator. The front doors can be locked/unlocked by the remote keyless entry (RKE) transmitter, the RKE keypad, the door lock control switch or the door lock cylinder.
