WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

VERIFY THAT THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE
NOTE: When diagnosing any WIN system concern, all the FOBIKS should be present.
1. Turn the ignition on.
  NOTE:
  Before continuing, review and check for the following:
  - Review the repair history of the vehicle.
  - Make sure that the vehicle has the correct PCM/ECM and WIN installed by verifying the part numbers.
  - With the scan tool, ensure that the PCM/ECM and WIN are programmed correctly. Compare the PCM/ECM VIN to the WIN VIN and ensure the two VINs match.
2. With the scan tool, record and erase the DTCs.
3. Perform three ignition cycles, leaving the ignition switch on for a minimum of one minute per cycle.
4. With the scan tool, read the active DTCs.
  Does the scan tool display; B1A6C-SECRET KEY MISMATCH as active?
  
  Yes
  - If the engine does not crank, go to step 2
  - If the engine does crank, go to 3
  No
  - Perform the WIN INTERMITTENT TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .

ENGINE DOES NOT CRANK

If this vehicle does not crank, use the table below to determine if the key is functional or not. With the scan tool under Data Display, Bussed Outputs, put the key in each position and check the "Ignition Status". Then with the key in the Run position, check "Valid Skim Key" and "SCREEM Status" reported by the WIN (or WCM). Compare all six readings with the "Good Key" column.

BUSSED OUTPUTS	-	-	-	-
Ignition Status	Good Key	Bad Key (Failed)	Wrong Key	New Key (Blank)
Ignition Position = Lock	-------------- or Lock	--------------	--------------	-------------- or Lock

  Does the scan tool show 2 or more Key/Fobs Programmed?
  
  Yes
  - Go to step 4
  No
  - Using the scan tool, program 2 FOBIKS.
  - Perform the WIN VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
CHECK OPERATION OF THE FOBIK IN USE
NOTE: Verify the FOBIK in use is the FOBIK causing the DTC to set.
1. Replace the FOBIK currently in use.
2. Using the scan tool, program the new FOBIK to the WIN.
3. Use the scan tool and erase all codes in the WIN.
4. Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
5. Wait one minute, and read active codes.
  Does the scan tool display this DTC as active?
  
  Yes
