Trouble with remote locks
 

Help please. I recently purchased a 1999 Sentra for my son with remote locks. I have changed the batteries in the remote pods and I had them tested at a Nissan dealership. They are putting out a signal just fine. I have reprogrammed the remotes with the instructions from a Nissan service sheet. I still can not get them to work. Does anyone know what else could be wrong? Is there a fuse or another part that I can check? Thanks in advance for any help.
