WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

I1 CHECK BOTH PATS KEYS
NOTE: Check to make sure the new PATS keys are approved Ford encoded PATS keys. Unapproved PATS keys do not always operate correctly over various temperature ranges. (PATS keys from Ford, Rotunda, Strattec or Huf are approved Ford PATS keys.)

NOTE: Follow this procedure using both PATS keys (using one at a time).
- Obtain both PATS keys from the customer and follow the procedure using one PATS key, then the other. If the customer only has one PATS key, it is necessary to cut a new PATS key (does not have to be an IKT key).
- If it is necessary to cut a new PATS key, cut the new key to match the original key. Program the PATS keys. Refer to INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT in this service information.
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve the IPC DTCs.
- Is DTC B10D7:05 present with either key?
- Yes : REPLACE the damaged key with the new key that was cut (if present), or CUT a new key to replace the damaged key. DISCARD the damaged key.
  PROGRAM the keys. REFER to INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT in this service information. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
- No : If other IPC DTCs are retrieved, REFER to the Diagnostic Trouble Code (DTC) Table in MULTIFUNCTION ELECTRONIC MODULES -- FUSION, MILAN & MKZ article.
  If no IPC DTCs are retrieved, the system is OK.
