i had the same thing happen to me, sometimes you can actually put too much lock stuff in the cylinder and gunk it all up preventing the key from turning, the only option you may have is to get a new steering column, or ignition set up, or you could just put a push button start in there and hide a kill switch for the accesories, if you have a spare key try that one and if it works your other key is probably just too worn, or if you have a friend with a mazda try there key, i know that my key will open and start 2 of my friends mazdas, kind of scary but it may work
hope something works out for you bro
