Hi all good day! Just recently bought an MPV 2007.

I just want to ask some questions, is there a way to program an old defective key fob to a new one? I just recently ordered a new key fob for my Mazda MPV 2007, can I program it with the car like the older versions of MPV or do I need someone professional to program it? I asked Mazda Motor groups here in New Zealand but they just asked me to contact a certain person but he/she won't answer at all ( maybe he/she is too busy). Anyway, are there other options to program it or do I have to go to a dealer with the car or can I just send my old key fob with the replacement so they can program it? Cheers
