2003 Jeep Wrangler TJ Rubicon 4.0L Manual ECM PCM Engine Computer SKIM Immobilizer Kit with Chipped Keys | Mopar 56044385AD

Save on expensive dealership programming fees with this Genuine OEM Mopar Plug-and-Play Engine Computer & Security Kit. This matched set was carefully pulled from a running 2003 Jeep Wrangler Rubicon with a 4.0L Inline-6 engine and a manual transmission.

Because Jeep TJ security systems lock the ECM to the vehicle's security module, replacing a single component usually triggers a no-start condition. This listing eliminates that headache by providing the complete, synchronized factory triad: the engine brain box, the anti-theft transceiver, and the verified transponder keys.

What's Included in This Kit:

1. Engine Control Module (ECM/PCM): Factory part number 56044385AD. Programmed for the 4.0L engine paired with a manual stick-shift transmission.
2. SKIM Immobilizer Ring / Transceiver: Factory part number 56010209AC. Mounts directly behind the ignition lock cylinder to read key chips.
3. Chipped Transponder Keys: Original matching gray transponder keys configured to communicate directly with this SKIM and ECM set. (Note: You will simply need to copy the physical cuts onto these keys or tape a key near your reader ring).

Technical & Condition Notes:

• Pre-Tested Quality: Thoroughly tested prior to vehicle disassembly to ensure full communication, stable voltage output, and flawless injector/coil circuit performance.
• Plug & Play Convenience: Installing this complete trio bypasses immediate SKIM security lockout codes, meaning your Jeep will start and run without requiring an immediate Mopar dealership programming tool.
