Fun fact: the actual metal key blank profile for the Mirage is the same as one used for some Geo cars, including the Tracker and Metro (Ilco B69 X180). I'll use one of those plain metal blanks we have laying around to make an emergency lockout key. It won't start the car, but it will unlock the door.
MIT17A-PH is the Ilco part number for the transponder blank that will also start the car (once programmed). Ilco is the biggest key maker in the world, so everyone uses their part numbers to identify key blanks.
