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

Read the full transcript
Symptoms of a bad skim or scream on your Dodge Chrysler Jeep vehicle. If your vehicle is experiencing a crank no start or a start install issue, listen up. Chrysler's Century Key Emobilizer Module or SKIM is infamous for locking you out. Symptom 1, the engine starts. The engine runs for exactly two seconds, then dies. Symptom 2, a flashing round security light or a crossed out key symbol illuminated on your dashboard. Symptom 3, a crank no start, accompanied by fault code P06, 3, 3, meaning skim key not detected. If your key transponder isn't communicating with the transceiver ring, your engine computer will automatically shut fuel delivery down. Do not replace that PCM just yet. Head on over to my website, try our Fitment tool out or put your make model in gear in the comments and we'll help you find the skim for your vehicle.
