Explorer AWD V8-4.6L (2010)
NOTE: This procedure is used when a customer needs to have an additional key programmed into the vehicle without erasing stored key codes, but
does not have 2 programmed keys available. This procedure is also useful when attempting to determine if an ignition key is damaged, as a new key can
be installed without erasing keys or without having 2 programmed keys available.
NOTE: Before programming, the new key must have the correct mechanical cut for the ignition lock cylinder.
NOTE: If 8 keys are already programmed, this procedure does not allow any more ignition keys to be programmed. The number of keys that are
programmed into the Passive Anti-Theft System (PATS) can be determined by viewing the Instrument Cluster (IC) PID N_KEYCODE.
NOTE: When in the unlimited key mode, the N_KEYCODE PID always reads 2 (after the first 2 keys have been programmed), no matter how many
keys are programmed to the vehicle.
1. Turn the unprogrammed PATS key from the OFF position to the ON position.
2. From the scan tool, enter TOOLBOX. Select BODY - SECURITY - PATS Functions and follow the Integrated Diagnostic System (IDS)
on-screen instructions to ENTER SECURITY ACCESS. For additional information, refer to Anti-Theft Security Access See: Accessories and
Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Component Tests and General Diagnostics.
3. NOTE: Make sure the selection made is "PROGRAM" (Program additional ignition key). If the "ERASE" (Ignition Key Code Erase) selection is
made, all of the keys are erased from the system.
From the scan tool menu select: "Program additional ignition key" and follow the IDS on-screen instructions.
4. Turn the key to the OFF position and disconnect the scan tool.
5. Start the vehicle with the new PATS key. The vehicle now starts with the new PATS key and also with the original PATS keys.

4. NOTE: If the IC or the IC and the PCM were replaced, updated or reconfigured, follow Steps 4-9. All vehicle keys are erased during the
parameter reset procedure. Verify at least 2 vehicle keys are available prior to carrying out the PATS parameter reset. If only the PCM was
replaced, go to Step 9.
