Ford Focus Service Manual: Key Programming Using Two Programmed Keys - General Procedures

Ford Focus Service Manual / Accessories / Security & Keyless Entry / Keyless Security System / Key Programming Using Two Programmed Keys - General Procedures

NOTE:

This procedure only works if 2 or more programmed ignition keys are available. If 2 keys are not available, refer to Spare Key Programming — Using Diagnostic Equipment in this section.

NOTE:

The Instrument Cluster (IC) PID SPAREKEY must be enabled for this procedure to operate. If this PID is not enabled, refer to Key Programming Switch State Control in this section. The IC SPAREKEY PID is set to "ENABLE" when the vehicle is built.

NOTE:

If the programming procedure is successful, the new key(s) starts the vehicle and the anti-theft indicator illuminates for approximately 3 seconds. If the programming procedure is not successful and the new key(s) does not start the engine, leave the key in the ON position for at least 3 seconds, then turn the key to OFF. Repeat the key programming procedure from Step 1. If the failure repeats, refer to Anti-Theft in the Diagnosis and Testing portion of this section to review the DTCs and carry out the appropriate pinpoint tests.

NOTE:

A maximum of 8 Passive Anti-Theft System (PATS) keys can be programmed into the Instrument Cluster (IC) during this programming procedure, but only if the IC PID SPAREKEY is set to "ENABLE".

NOTE:

A minimum of 2 PATS keys must be programmed into the IC before the vehicle starts. If the MyKey™ function is enabled, one or both of the keys must be administrator (admin) keys.

NOTE:

If the vehicle is in unlimited key mode, this spare key programming procedure still functions. Any 2 keys that can start the vehicle can be used to program an additional unlimited key.

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:

If the steps are not carried out as outlined, the programming procedure ends.

NOTE:

Ignition keys must have a correct mechanical key cut for the vehicle and must be PATS encoded keys (contain a transponder).

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 .

NOTE:

When in the unlimited key mode, the IC 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 first, programmed PATS key into the ignition lock cylinder and turn the key from the OFF position to the ON position (maintain the key in the ON position for a minimum of 3 seconds and less than 10 seconds).
  1. Turn the first PATS key to the OFF position and remove the key from the ignition lock cylinder.
  1. Within 10 seconds of turning the first PATS key to the OFF position, insert the second, programmed PATS key into the ignition lock cylinder and turn the key from the OFF position to the ON position (maintain the key in the ON position for a minimum of 3 seconds and less than 10 seconds).
  1. Turn the second PATS key to the OFF position and remove the key from the ignition lock cylinder.
  1. Within 20 seconds of turning the second, programmed PATS key to the OFF position, insert the unprogrammed PATS key (the new key) into the ignition lock cylinder and turn the key from the OFF position to the ON position (maintain the key in the ON position for a minimum of 3 seconds and less than 10 seconds).
  1. Start the vehicle with the new PATS key(s).
  1. If it is desired to program additional PATS key(s) (only up to 8 keys total can be programmed into the IC ), repeat Steps 1-6 for each additional PATS key that needs to be programmed.
