You don't need the dealer to do this - look in the book at the section that talks about LOCKS, and it will tell you how to program it yourself.
The way I set it is that when you touch the DRIVER's Door, that's the only one that opens, but when you touch the DRIVER'S PASSENGER door, all of them open.
That way, if I'm with my wife, I just touch the back door handle as I approach the car and still have the ability to only open the front door if I'm alone.
