You must bring your car into an official Mazda Dealership. Bring all of your keys with you as they will have to "reset" the on board computer and register all keys at the same time. The cost of the key is about $40 and they will charge you about $90 for labor. Unfortunately, there is no way to get around the labor cost as you need a special machine to code the keys. the FOB is a different story. just buy one on eBay for about $30 and program it yourself.
