You should first contact their local Mazda dealership or locksmith. This is a viable option as it's likely be less expensive and quicker than calling a truck.

When you insert your key and then turn it to ON, the antenna ring releases an impulsive radio frequency energy that gets to the transponder chip that's in the metal key. The chip responds with the code that's sent to the antenna ring, telling the car that it's an authentic key.

Most Mazdas have transponder chips equipped with a code that is changing each time you turn it. This means that the key will not work with your vehicle until you have a duplicate with the exact same code in the ignition.

Fortunately, it's not impossible to create your own replacement keys. If you can locate a working key, place it in your Mazda and turn the ignition to ON.

You can do this in only a few steps and you will not need to pay the dealer for the service. You can avoid paying for a tow or dealership fees if you own an additional car key.

The screwdriver's tip should fit in a small slot or a space on the side of the fob. After removing the case replace the old battery.

It's time to add the new key fob in your vehicle. Insert the first key that works into the ignition and turn it ON. Then, wait for five seconds and then turn the ignition off. Repeat the process with a second key that works as well, and then the new (or additional) key. After you've done this then your Mazda should have the ability to be started using the newly programmed keys. If it's not, it might be a problem with the key fob.
