You shouldnt have to program the remote after you change the battery...just hold LOCK and UNLOCK down for 7 seconds to resync the remote to the receiver.

If you have 2 remotes, and then change the battery on one, and do the whole program procedure again, you'd have to reprogram the 2nd remote as well.

hey guys thanks...i tried both and neither worked...i will be takin it to the dealer this week..thanks for the help.
