Deactivating Theft Deterrent - Radio in "LOCK" or "- - - -" Mode (Code Unknown)

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

When the theft deterrent feature is armed or secure (SEC), the radio can enter the locked state if the power is removed from the radio for greater than 20 seconds or an incorrect code is attempted 3 times. An error message is displayed after every wrong entry.

When the radio is in the LOCK (locked) mode, "LOCK" is displayed and all radio functions are disabled.

Before another attempt at the correct code can be made, the radio must be ON and the display must show "LOCK" for an hour. After an hour, "- - - -" will be displayed and the correct code may be entered using the following steps:

If the customer code is unknown, perform the following steps to retrieve the customer code:

  1. Turn ignition ON.
  2. Turn radio power OFF.
  3. Press and hold preset buttons "1" and "2" for 5-seconds. A 4-digit code will be displayed. This number is not the customer's code. Record this number as it is needed before technical support is called.
  4. Using a touch tone phone only, call the technical support system at 1-888-225-2306 (USA & Canada). When advised, give the following information:
    1. Your retailer code.
    2. The 4-digit radio display code obtained in step 3.
    3. In response, you will receive the factory unlock code; record this number.

      NOTE: The factory unlock code received is the same as the code that was entered by the customer.

  5. Turn ignition ON.
  6. Press the radio power button. The display will show "- - - -".
  7. Enter the four-digit code by using the SEEK/SCAN and TUNE rocker buttons. The numbers will start at 0000 and will increase on the display each time the corresponding side of the rocker button is pushed.
    1. Press the down arrow side of the SEEK/SCAN rocker button to change the left digit.
    2. Press the up arrow side of the SEEK/SCAN rocker button to change the second to left digit.
    3. Press the down arrow side of the TUNE rocker button to change the third to left digit.
    4. Press the up arrow side of the TUNE rocker button to change the fourth to left digit.
  8. Press the AM/FM button after entering the 4-digit code. If the correct code has been entered, the radio will return to the SEC (armed) mode and normal operation will return. If the wrong code has been entered, the display will show an error message and display "- - - -" indicating another attempt at the correct code can be made.
