Hello and welcome to JA!!!
I'm Billy and i will assist you with this.
As for the fob remote function, you may try and replace the battery of the fob, and then resync and it should work....

If that does not work, you will need to check for any blown fuses, and if none is found, you need to remove the door trim panel (of the n/s/f door) and check the operation of the lock actuator, it may need some WD40 to make it work again, or it maight need replacing.
I will post the info, on how to remove the door trim panel in order to check that out:

After you get that lock actuator working, try the re sync procedure again, and the problem should be solved...
Best wishes for 2011!!!
