It is probably the door lock actuator inside the door. I've replaced a lot of them for this concern.

ok, is that something we can do, or do you suggest a dealer do it? any idea of a rough cost for the part/labor?


It can be done at home but find a youtube video or some other detailed instructions including the tools needed. I have a lot of handy dandy specialized tools that make it easier to do but with a little patience and time it's a Saturday afternoon of wondering if the engineer that designed it was mad at you specifically.
