Mariner 4WD V6-3.0L (2010)
of the vehicle keys so they contain the same key code.
NOTE: When in the unlimited key mode, the N_KEYCODE PID will always read 2, no matter how many keys are programmed to the vehicle (after the
first 2 keys have been programmed).
1. The customer must choose an 8-digit number (except for 00000000 or 00000001) to be programmed to all of their vehicles. All customer vehicles
need to use the same number. Valid digits are 0-9 and the letters A-F.
2. NOTE: If the PID UNL_KEY_ID is not available, unlimited key mode is turned on and must be turned off before viewing the stored code. At this
time, unlimited keys can be programmed to the vehicle. To view/change the stored code, follow the procedure for disabling the unlimited key
mode below.
Monitor the PID UNL_KEY_ID and compare its value against the code chosen in Step 1. It should not be the same key code.
3. 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.
4. Once in security access, select: "program unlimited key code" and follow the IDS on-screen instructions. Enter the 8-digit code chosen by the
customer in Step 1 of this procedure and follow the IDS on-screen instructions.
5. Select: "unlimited key mode ON" and follow the IDS on-screen instructions.
6. Select: "Ignition Key Code Erase" and follow the IDS on-screen instructions.
7. Disconnect the scan tool and turn the ignition key to OFF (the key does not need to be removed at this time).
8. Turn the first PATS key in the ignition lock cylinder to the ON position for 3 seconds (6 seconds if it is an IKT key).
9. Turn the first PATS key to the OFF position and remove the key from the ignition lock cylinder.
10. Insert the second PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds (6 seconds if it is an IKT key).
11. Start the vehicle with both PATS keys to verify their correct operation.
12. If it is desired to program additional key(s), refer to Key Programming Using Two Programmed Keys See: Accessories and Optional
Equipment/Antitheft and Alarm Systems/Testing and Inspection/Programming and Relearning/Anti-Theft - Passive Anti-Theft System
(PATS)/Key Programming Using Two Programmed Keys for each additional key that needs to be programmed.
Disabling Unlimited Key Mode
NOTE: By disabling the unlimited key mode, the previous access code no longer operates the vehicle.
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 See: Accessories and
Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Component Tests and General Diagnostics.
2. Select: "unlimited key mode OFF" and follow the IDS on-screen instructions.
3. Select: "Ignition Key Code Erase" and follow the IDS on-screen instructions.
4. Disconnect the scan tool and turn the ignition switch to OFF (the key does not need to be removed at this time).
5. Turn the first PATS key in the ignition lock cylinder to the ON position for 3 seconds (6 seconds if it is an IKT key).
6. Turn the first PATS key to the OFF position and remove the key from the ignition lock cylinder.
7. Insert the second PATS key into the ignition lock cylinder and turn the key to the ON position for 3 seconds (6 seconds if it is an IKT key).
8. Start the vehicle with both PATS keys to verify their correct operation.
9. NOTE: With the unlimited key mode turned off, a maximum of 8 keys can be programmed into the IC using the Key Programming Using Two
Programmed Keys See: Accessories and Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Programming and
Relearning/Anti-Theft - Passive Anti-Theft System (PATS)/Key Programming Using Two Programmed Keys procedure. The IC PID SPAREKEY
must be set to ENABLE.
