My 1991 Cutlass Supreme had a phantom RKE problem. We took it to a shop, and the mechanic was holding the door lock fuse in his hand and it still spazzed out. Got worse in the summer, less so in the winter. We never figured it out, it just sorta went away on its own.

My guess is its just a short somewheres that's making intermittient contact, i.e. insulation rubbing away.
