PKFM is the new & improved upgradeable Ford/Mazda data transponder override. PKFM is based on the best selling XK04 platform but improves on the coverage of 2006-09 vehicles with several hardware upgrades including an integrated relay. Like XK04, PKFM is preloaded with PKFORD firmware, and data interfaces directly with the PATS module to temporarily override the factory immobilizer when remote starting.
