How do I change the lock code on my Samsung Convoy 4?

You can change the Phone Only lock code (used to lock and unlock your device) and the Calls & Services lock code (used for restricting access to calls and other features). The last four digits of your phone number are the default lock code for both on your device.

• Changing the lock code for Phone Only does not change the lock code for Calls & Services, and vice versa.
• You can have a different code for Phone Only than for Calls & Services.

Changing the Phone Only Lock Code

  1. From the Home screen, press the OK key.

  2. Use the Directional key to highlight Settings and press the OK key.

  3. Use the Directional key to highlight Phone Settings and press the OK key.

  4. Use the Directional key to highlight Security and press the OK key.

  5. Enter your lock code. 

    The default code is the last four digits of your phone number.

  6. Press the OK key to select Edit Codes.

  7. Press the OK key to select Phone Only.

  8. Use the keypad to enter a new four-digit lock code. You will be asked to enter the new code twice for verification.

Changing the Calls & Services Lock Code

  1. From the Home screen, press the OK key.

  2. Use the Directional key to highlight Settings and press the OK key.

  3. Use the Directional key to highlight Phone Settings and press the OK key.

  4. Use the Directional key to highlight Security and press the OK key.

  5. Enter your lock code. 

    The default code is the last four digits of your phone number.

  6. Press the OK key to select Edit Codes.

  7. Use the Directional key to highlight Calls & Services and press the OK key.
