Factory Invoiced Accessory (FIA) Remote Starter
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles may be equipped with a remote start system that is a dealer-installed but Factory Invoiced Accessory (FIA). The remote start fob for this system uses a small device that is about half the size of a conventional RKE fob, but only has one button on it. If the remote start system is installed on the vehicle and the unlimited mode is not enabled, the PATS allows up to 7 PATS keys to be programmed into the IC . The remote start system uses up 1 of the 8 total PATS keys that can be programmed into the IC . The number of keys that are programmed into the PATS can be determined by viewing the IC PID N_KEYCODE.
