Today, your car's high-tech key fob can do more than just lock and start your car, and that added convenience comes with a cost: more expensive replacements.

The key fob is equipped with a security chip built into it that sends a specific code to the car's computer to allow you to unlock and start the engine. The key fob is also capable of controlling other functions, such as closing the windows if you're in a hot parking area and summoning your car for easier reversing into an awkward spot (a feature found on some Genesis GV60 and Hyundai Sonata sedans).

Lockouts

You should first contact their local Mazda dealership or locksmith. This is a good idea because it's likely to be less expensive and more efficient than calling a tow truck.

Transponder Chips

Most Mazdas use a transponder chip with a rolling code that changes its code every time you turn the key. This means that the key you're using isn't going to work with your car until you have a duplicate with the same exact code in the ignition cylinder.

The screwdriver's head should fit into a small slot on the side of the fob. After removing the case, replace the old battery.

Now you can program your new key fob. Insert the first key that works into the ignition and turn it ON. For about five seconds, and then turn off the ignition. Repeat the process with a second working key, and then with your new (or spare) key. Once you've completed the process and the key that you have programmed should be in a position to start your Mazda. If it doesn't, there may be another problem with your key fob or vehicle.
