This is a complete remote with internal circuit board and chip
Notice:
Pls make sure your key is exactly the same as ours(the same shape, buttons and part number), then it will work.
You need to have this aftermarket key cut and programmed 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 it does not work. A locksmith is fast and inexpensive compared to a dealer.
