Will only start with my keyless remote
 

My 2010 Mazda 3 will not start with my key but will start with the key-less remote ( installed by Mazda). Once I have it started I can insert my key and drive. This has to be something minor, like resetting something? Any help would be awesome:

do you have the switchblade key style? if so the battery may have died in the fob or the key may not have been programmed.
