Flex FWD V6-3.5L (2010)
NOTE: The unlimited key mode is set up by creating a special, unique unlimited transponder security key code and programming this key code into all
of the vehicle keys so they contain the same key code.
NOTE: When in the unlimited key mode (after the first 2 keys have been programmed to the vehicle), the N_KEYCODE PID in the IC always reads 2,
no matter how many keys are programmed to the vehicle.
1. The customer must choose an 8-digit number (except for 00000000 or 00000001) to be programmed to all of their vehicles keys (or, to all of the
keys they want programmed to one vehicle). All customer vehicles keys (or all keys for one vehicle) need to use the same number. Valid digits are
0-9 and the letters A-F.
2. NOTE: If the IC 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 may be programmed to the vehicle(s). To view/disable/change the stored code, follow the procedure "Disabling
Unlimited Key Mode" below.
Monitor the IC 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 and follow the on-screen instructions.
5. Select: "unlimited key mode ON" and follow the 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 the OFF position (the key does not need to be removed from the ignition lock cylinder at this
time).
8. Turn the first Passive Anti-Theft System (PATS) key 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. The vehicle should start with both PATS keys.
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/Key Programming Using Two Programmed Keys
for each additional key that needs to be programmed.
