I have a 2011 FX35. I want to add an additional remote. Understand I can have up to 4 of them programed to the vehicle and it has to be done at dealership level or a locksmith as the process is not a DIY deal. The key itself has no chip from what I understand and does not require any special handling other than getting it cut. I've got the part number and plan on buying them off one of the Infiniti Online places as it's much cheaper. The guy behind the parts counter says the part number is correct. Do I need to stay with the same FCC ID that's currently on the back of the other remotes? At no time have I been asked what that ID is. I'm just trying to avoid buying this and it not working when I make the appointment to have it programmed. Thanks
