Does anyone know the best way to have a duplicate master key with the unlock/lock fob? I have seen oem keys on ebay for about $124 but it still needs programming and the key will need to be cut. I currently have 2 keys- 1 master and 1 gray valet key. Can I program a new key if I have a master key on hand? I got quoted $250 for a duplicate programmed master. This seems pretty high, Any suggestions? Thanks

You can buy oem key and then cut it. To cut the key is anywhere between 5-$20. If you have master key then programming is very easy. Local locksmith charged me $35 for programing. Make sure that locksmith specialize in transponder keys.
