Ford Focus Service Manual / Accessories / Security & Keyless Entry / Keyless Security System / 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 keys programmed into the system and does not have 2 programmed ignition keys available. This procedure is also useful when a programmed ignition key(s) is lost or the ignition lock cylinder is replaced, and it is desired to erase key code(s) from the Passive Anti-Theft System (PATS) memory.

NOTE:

This procedure erases all programmed ignition keys from the vehicle memory. The vehicle does not start until a minimum of 2 keys are programmed into the Instrument Cluster (IC) .

NOTE:

It is necessary to have 2 PATS encoded (contains a transponder) keys with the correct mechanical cut to carry out this procedure. One or both of them may be the customer's original keys.

NOTE:

If additional keys are to be programmed, and the remaining keys are with the customer, or are not available, instruct the customer to refer to the Owner's Literature for instructions on programming the remaining keys. In this case, the IC PID SPAREKEY must be set to ENABLE.

NOTE:

This procedure is not necessary if only the PATS transceiver was replaced. Replacement of the transceiver does not erase the PATS key codes in the IC .

  1. 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. From the scan tool menu select: "Ignition Key Code Erase". Follow all IDS screen instructions until the key erase procedure completes. The scan tool also instructs to program 2 keys to complete the process.
  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) (the key does not need to be removed at this time).

  1. Turn the first PATS key to the ON position for 3 seconds.
  1. Turn the first PATS key to the OFF position and remove the key from the ignition lock cylinder.
  1. Insert the second PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds.
  1. If it is desired to program additional key(s) (only up to 8 keys total can be programmed into the IC ), refer to Key Programming Using Two Programmed Keys in this section for each additional key that needs to be programmed.
  1. Start the vehicle with all of the programmed PATS keys to verify their operation.
