My brother bought a '90's firebird for $200 that was missing the keys. The dealer checked all codes and could not figure out what the key was supposed to be, since this particular firebird VIN said it didn't come with security keys. long story short is we believe the VIN tags were from a different firebird, and installed on this one that had Trans-am parts. we measured the resistance of the little spot on the key, bought some resistors at radio shack, wired them together, cut the wires off the ignition key switch, wired our resistor pack in, and voila! no need for a security key in his car anymore... probably nothing like the Jeep Key of the '00's though... since there is no little dark bubble in the middle of the metal part of the key
