From the shop
This SKIM (Sentry Key Immobilizer Module) carries part number 56038665, with interchange numbers 56038665AX, 56038665AT, and 56038665AS, and fits the 2005–2006 Chrysler 300, 2005–2006 Dodge Magnum, and 2006 Dodge Charger. It's a used OEM module, tested, and will require re-programming to your VIN by a dealer or locksmith after install. On these cars, a failing SKIM is a common reason the engine cranks but won't start, or the theft light stays lit even with a good key in the ignition. Message me if you want help sorting the interchange numbers before you order. — Hubes
