They should first try calling their local Mazda dealership or locksmith. This is a good idea since it's likely to be cheaper than calling a tow truck and will be quicker as well.

If the key is able to start your car, you can then copy the information from it to the other key. If necessary, you can also utilize the eraser on your key fob in order to erase the code. This method isn't certain to be successful, as some transponder chips recycled might not function correctly.

It's time to add the new key fob to your vehicle. Insert the initial key that works into the ignition and turn it ON. For about five seconds, and then switch off the ignition. Repeat the process with a different working key, and then with your new (or spare) key. Once you've completed the process your newly programmed key should be in a position to start your Mazda. If it's not, it may be a problem with the key fob.
