What You Need to Know About Mazda Car Key Replacement Mazda keys are made up of a variety of electronic components that must be functioning properly for the car's ignition to function.

When you need a new key for your car the locksmith will need to know what kind of chip is in your current Mazda key, and whether it has an integrated chip in the key fob or if it is a separate chip in the head of the key that fits into the ignition lock.
