I did this because the the normal two piece key fob is a little 90's style. I like the one piece cause it looks nicer and doesnt clank as I walk around with it attached to my belt. I bought mine from Xluben. The older 08 model needed a change of the receiver to a legacy model. It was a slight pain to find the right parts but the install wasnt as bad as I thought. Programming it was easy as well, dont let that stop you. I'd recommend to those with a 11+ since it's easier for them. The biggest pain with these was cutting the new blade if you do not use your old ones. Price was for all the box and 2 keys.
