A: If the key and skim module is original to the vehicle then you can get the pcm vin flashed. Otherwise if the key and skim module don't match the vehicle then the skim delete option is the best route.

Jeep Grand Cherokee SKIM Key & WIN Immobilizer Delete Service
Did you replace the PCM/ECU in your Jeep Grand Cherokee only to have the engine start and then immediately stall? A faulty SKIM (Sentry Key Immobilizer Module) or WIN (Wireless Ignition Node) often blocks the PCM from allowing the engine to run. Our in-house SKIM / WIN Immobilizer Delete Service permanently removes this security programming from your Grand Cherokee PCM.
What This Service Does
- SKIM / WIN Removal — disables the factory immobilizer to eliminate no-start conditions
- VIN Re-Write — your VIN is written back into the PCM after security removal
- Permanent Fix — allows PCM swaps without triggering immobilizer issues
Important Notes
- SKIM/WIN Module Handling — the SKIM/WIN module must be unplugged before installing a PCM with security cleared (2007+ WIN systems may have specific handling)
- Security Light — some vehicles may still show the security light after SKIM delete; this does not affect drivability
- Plug & Play — most SKIM-cleared PCMs are install-ready; in rare cases a global code clear is needed before the vehicle starts
How SKIM/Immobilizer Works
Every Jeep PCM is SKIM-capable, even if the vehicle did not originally include the system. Once activated, the PCM always looks for a SKIM/WIN signal. By clearing the SKIM function, the PCM will operate normally without the immobilizer system. Both security and non-security keys can be used with a SKIM-cleared PCM.
