How can I replace the RFID on the Mazda key fob
Mazda key fobs, also referred to as Mazda transponder keys or chip keys, have an RFID (Radio Frequency ID) chip that acts as an anti-theft device.

Even a perfectly-replicated copy of the key cannot start the car without this chip. But what if the chip in the key fob of your car dies?
