Holden quoted me $30 to "coded" the key, buy i had to have the blade cut first by a locksmith. This cost me $17.50.
I went to get this done at the locksmith and walked out to my car and remember someone mentioning a little trick where you press the unlock key of your working key and then place the newly cut key and unprogrammed head into the ignition and count to 5, then turn the key to ACC and count to 5 and then start the car. and my car started. i left it there for 30 seconds and removed the key.
My key now starts my car and unlocks and locks the doors. Not sure if this is a way you can get around paying for the head to be coded or if the lock smith that cut my blade actually coded the head when they said they wouldn't for $17.50. they charge $27.50 to code the head if you already have one.
All i know is that i have a key head and blade from ebay and got it cut for under $50 total.
