Ford Focus Service Manual: Spare Key Programming - Using Diagnostic Equipment - General Procedures

Ford Focus Service Manual / Accessories / Security & Keyless Entry / Keyless Security System / Spare Key Programming - Using Diagnostic Equipment - General Procedures

Special Tool(s)

Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

NOTE:

This procedure is used when a customer needs to have an additional key programmed into the vehicle without erasing the 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 programmed 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 Passive Anti-Theft System (PATS) keys to be programmed without erasing all stored key codes first. The number of keys that are programmed into the PATS can be determined by viewing the Instrument Cluster (IC) PID N_KEYCODE.

NOTE:

When in the unlimited key mode, the PID N_KEYCODE always reads 2, no matter how many keys are programmed to the vehicle (after the first 2 keys have been programmed).

  1. Insert the new, unprogrammed PATS key into the ignition lock cylinder and turn the key from the OFF position to the ON position.
  1. 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 in this section.
  1. NOTE:

    Make sure the selection made is "Program additional ignition key". If the "Ignition Key Code Erase" selection is made, all of the keys are erased from the system, and the vehicle does not start until a minimum of 2 keys are programmed into the IC .

    From the scan tool menu select: "Program additional ignition key" and follow the IDS on-screen instructions.

  1. NOTE:

    The 20-second delay is to allow the module to exit the diagnostic mode.

    Turn the key to the OFF position and disconnect the scan tool (wait 20 seconds).

  1. Start the vehicle with the new PATS key. The vehicle now starts with the new PATS key and also with the original PATS keys.
