+1 Yah this is a good first step....
Unless you have an issue like I have on my other key.
I can program, my key, and it "seems" to work... until i try to use the key 30 mins later and it will not start the car. I can lock/unlock the doors, but won't start the car at all.
"PLEASE NOTE: This programming procedure programs the remote control part of the key. Any transponder chip for the immobiliser (starting of car) will not be programmed and must be done by a specialist..."
