If the key starts your car, you'll then be able to copy the information from it to the other key. If you're in need, you can also use the eraser on your key fob in order to erase the code. It's important to note that this method isn't certain to work as certain transponder chips that have been recycled might not work correctly.

Programming

The screwdriver's tip should fit into a small slot or a space on the side of the fob. After you've removed the case, you'll need to replace the battery that was in the case with a new one.

Now it's time to set up the new key fob in your vehicle. Insert the first key that works into the ignition and turn it ON. It should be on for about five seconds and then turn off the ignition. Repeat the process with a second working key, then your new (or spare) key. Once you've completed the procedure then your Mazda should have the ability to be initiated using the newly-programmed keys. If it's not, there may be a problem with the key fob.
