If you've never had the insides of the doors worked on, then YES, gumming up is the most likely cause.
OEM grease deteroirates, dirt accumulates etc, leading to failure.
I did a complete tear down of my drivers side door, last year, detailing everything, and once the latching mechanism was pristine, it worked like a charm, very little effort needed by key or actuator to lock/unlock the doors.
