Genuine OEM IMMOBILIZER TRANSCEIVER ANTI THEFT PATS (56038665) for the Dodge. Direct-fit replacement.

From the shop

The SKIM module controls key recognition and fuel pump authorization on the 2005–2007 300, Charger, and Magnum — when it fails, the car cranks but won't start, and the theft light flashes. This is an OEM unit that will require re-programming to your VIN by a Chrysler dealer or a qualified locksmith before it'll recognize your keys. That step takes about 20 minutes and is standard for any SKIM swap. Part number 56038665. — 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.
