Bought it used, got a killer deal, and was just informed after 2 days that the car dealership who is not car make specific lost the 2nd smart card or can't find it. So now I'm searching everywhere high and low to get a replacement for less than $535 the closest New Mazda dealership wants to charge. I tried calling a few locksmiths also and no dice so far, one I have to call one last one highly recommended Monday after they open. So from my understanding, I have to have the smart card to start the car(can this be bypassed?). I have to have 2 working smart cards to program a 3rd. Right now, I have 1 smart card 0 key blades/emergency keys and the smart card i have works only half the time replaced the battery today and that made no difference. Can I buy a blank transponder key and have it cut and programed by a locksmith using the vin# of my car? All I want to do is have at least 1 emergency key blade for the time being. But if anyone knows of a better route please let me know, I'm pulling my hair out trying to figure this out. Starting a car should never be this hard.
