Seems these programmings are very much dealer, and relationship dependent. My local dealer who is not very reputable and also known to be a "rip-off," surprisingly did both of mine for only $25. It's a good idea to become "chummy" with the service and parts departments...if you're a nobody to them, they'll charge you. If they know you and you've shot the "bull" with them and sometimes take them a box of donuts, etc., they're more apt to do this simple (at least from their perspective) task for little or nothing.
