automatic door locks

My automatic door locks no longer work. what would be some problems with solutions. i am trying to keep it out of a repair shop, because i just spent 250 dollars on a new speed sensor!

is it just the remote that doesn't work? or the locks don't work from the inside of the car either? If they don't work at all, I'd check a fuse

they don't work from the side key pad or the inside, what fuse would that be?

there should just be a fuse marked "door lock" or somethin to that extent, shouldn't be to hard to locate.

You might have to pull all the fuses and check them one by one since there doesn't seem to be one clearly marked for door locks.. I'd start with the 'Elec Parts' ones on the inside (dash by left knee). Check the ones under the hood too in the long fuse box beside the driver's side fender. It could be a keyless entry fuse that blew, but I can't remember what all is in the exterior box.
