The following instructions explain how to enter a secret code to activate the THEFTLOCK™ system.

Read all nine steps before starting the procedure.

Important: If more than 15 SECONDS is allowed to elapse between any steps, the radio automatically reverts to displaying time and the procedure must be started over at Step 4.

1. Write down any three or four-digit number from 000 to 1999. Keep the number in a safe place separate from the vehicle. This number is the secret code.
2. Turn the ignition to the ACCESSORY or ON position.
3. Turn the radio OFF.
4. Press the number 1 and 4 push buttons at the same time. Hold the number 1 and 4 push buttons down until "- - -" appears on the VF display.
5. Press MN.

000 will appear on the display.

6. Press MN again until the last two digits agree with the last two digits of the secret code.
7. Press HR until the first one or two digits agree with the first one or two digits of the secret code.
8. Press AM/FM after confirming that the display code matches the secret code. REP appears on the display indicating that steps 5 through step 7 need to be repeated to confirm the secret code.
9. Press AM/FM again. SEC appears on the display indicating that the radio is secure. The indicator light by the PWR-VOL control begins flashing when the ignition is turned off.

Enter the secret code as follows pausing no more than 15 seconds between steps:

1. Turn the ignition to the ACCESSORY or ON position.
2. Turn the radio OFF.
3. Press the number 1 and 4 push buttons at the same time. Hold the number 1 and 4 push buttons down until SEC appears on the VF display.
4. Press MN.

000 will appear on the display.

5. Press MN again until the last two digits agree with the last two digits of the secret code.
6. Press HR until the first one or two digits agree with the first one or two digits of the secret code.
7. Press AM/FM after confirming that the display code matches the secret code. "- - -" appears on the display indicating that the radio is no longer secured.

SEC appears if the code is incorrectly entered. The radio will remain secured until the correct code is entered.

When battery power is supplied to a secured radio, the radio will not turn ON and LOC will appear on the display.

Enter the secret code as follows pausing no more than 15 seconds between steps:

1. LOC appears on the VF display with the ignition ON.
2. Press MN.

000 will appear on the display.

3. Press MN again until the last two digits agree with the last two digits of the secret code.
4. Press HR until the first one or two digits agree with the first one or two digits of the secret code.
5. Press AM/FM after confirming that the display code matches the secret code. SEC appears on the display indicating that the radio is now operable and secure.

INOP appears on the display if a wrong code is entered after eight attempts to enter the correct code. Wait one hour with the ignition ON before trying again. Only three attempts are allowed when retrying to enter the correct code before INOP appears.

Important: In order to display this code the radio should be in LOC mode or have SEC displayed before proceeding. Pause no more than 15 seconds between steps:

1. Press and hold push button numbers 2 and 3 for about 6 seconds until the first 3 digits of the display code appear.
2. Write the numbers down.
3. Press AM/FM to display the second set of 3 digits.
4. Write the numbers down.

After approximately 5 seconds, or if another button is pressed, the display returns to LOC. The display code must be unscrambled to get the factory backup code which unlocks the radio. Refer to Radio Theft-Deterrent, Factory Backup Code.

If the security is activated and the radio is disconnected from battery power, the radio will display LOC. The radio will not turn on until the correct unlocking code is entered. If the customer code is lost or unavailable, refer to the Dealer Communications System bulletin about the unlock procedure.

Important: The radio must be unlocked and no owner's code can be currently stored in the radio to change the owner's code. The radio will display 1:00 when unlocked. To determine whether or not there is an owner's code stored press and hold push button numbers 1 and 4 until the display changes. If SEC is displayed there is an owner's code stored. If "- - -" is displayed there is no code stored.

To Remove Owner's Code

(To Deactivate the Theft-Deterrent From the Unlocked Mode, Deterrent Activated:)

Important: Either the owner's code or the factory backup code can be used to remove the owner's code.

Important: The theft-deterrent is already deactivated and no code is stored if the display changes to "- - -".

1. Turn the radio OFF. Press and hold push button numbers 1 and 4 for about 6 seconds until the display changes to read SEC.
2. Press HR to set the first two digits (0-19) of the code.
3. Press MN to set the next two digits (0-99) of the code.
4. Press the AM/FM button to enter the code.

Theft-Deterrent is deactivated when "- - -" appears on the display and then the time of day displays.

To Add Owner's Code

(To set the User Code (Activate) From the Unlocked Mode, Deterrent Deactivated:)

Important: If SEC displays, the theft-deterrent is already activated. This means the old code must be removed before entering a new code.

1. Turn the radio OFF. Press and hold push button numbers 1 and 4 for about 6 seconds until the display changes to "- - -".
2. Press HR to set the first two digits (0-19) of the code.
3. Press MN to set the next two digits (0-99) of the code.

Important: If "- - -" displays after pressing AM/FM, the owner's code has not been entered.

4. Press the AM/FM button to enter the code.
5. When REP then 000 are displayed, repeat steps 2 through step 4. This confirms the owner's code and activates the theft-deterrent. SEC appears on the display indicating that the theft-deterrent is active, then the time of day appears on the display.

Anytime battery power is cycled and ignition is applied the LOC appears on the display. The system locks. To unlock the system use the owner's code or the factory backup code. Refer to Radio Theft-Deterrent Unlocking After Power Loss.
