Programming:
You need to have this key blade cut by a local locksmith. DO NOT go to the DEALER they will charge you for ONE HOUR of labor and they tend to want to sell you one of their remotes and often will not program the remote for you or they may charge you and then claim i does not work. A locksmith is fast and inexpensive compared to a dealer.
