The auto door lock function is beginning to fail. on 2004 Saturn LW300

It is all doors and the FOB and door lock button seem to activate it just slightly, so you have to press the button several times to get the door to lock or unlock. I think it must be some command module failing. I would like the part number and the difficulty in replacing it.
Thanks, JOHN

try new batteries in your fob
Thanks for the reply!!! Good suggestion, however, the switch (button) in the car does the same as the FOB. It seems the solenoids that pull the door locks down are not getting the enough of a "pulse".
