If you have followed the disarm procedure listed in the owners manual exactly and the system won't shut down then your only choice is the dealer, they will have to access the system and totally reset the security protocols. Make sure you take all of the keys with you so they can make sure the system reads them all.

You can try locking then unlocking the vehicle with the key fob but if that doesn't work, as tennisshoes said, you're going back to the dealer. HTH. -Jim
