Lockouts

When you insert your key and then turn it to ON, the antenna ring releases an impulsive radio frequency energy that will reach the transponder chip within the key's metal. The chip then responds with an encoded code that is transmitted to the antenna ring telling the car that it's a valid key.
Most Mazdas utilize a transponder chip that is rolling code which changes its code each time you turn the key. This means that the key you're using isn't going to be compatible with your vehicle until you've got a duplicate with the exact code in the ignition cylinder.
