From the shop

The SKIM on '98–'04 Grand Cherokees fails when the theft light stays on and the engine won't crank, even with a good key and battery. This module handles immobilizer logic and fuel pump relay — when it goes, the truck goes nowhere. OEM tested, direct fit for your Grand Cherokee. You'll need your dealer or a locksmith to program the module to your existing key after install. Ships Mon–Fri before 3pm EST. — 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.
