Lock your device with a password

Looking for a simple way to help protect your BlackBerry device data and prevent unauthorized use of your device? You can set a device password so that you can lock your device when it's in open view or not in use.

  1. If you don't have a password, on the home screen, swipe down from the top of the screen. Tap image Settings > Security and Privacy > Device Password. Turn on the Device Password switch. Enter a password.
  2. To lock your device, do one of the following:
    • Press and hold the Power/Lock key. Tap The Lock icon.
    • To automatically lock your device after a certain amount of time, on the home screen, swipe down from the top of the screen. Tap image Settings > Security and Privacy > Device Password. In the Lock Device After drop-down list, select an interval.

    • To allow an active app to override when your device locks, for example, so your device does not lock while you are watching a movie in the Videos app, on the home screen, swipe down from the top of the screen. Tap image Settings > Security and Privacy > Device Password. Turn on the Allow Apps to Extend Password Lock Time switch.
To unlock your device, press the Power/Lock key. Swipe up from the bottom of the screen. When prompted, enter your device password.

Lock your device with your work space password

If your BlackBerry device uses BlackBerry Balance technology to separate your work and personal activity, you might be able to use the same password for your work space password and your device password, depending on the rules set by your administrator.

  1. On the home screen, swipe down from the top of the screen.
  2. Tap image Settings > Security and Privacy > Device Password > BlackBerry Balance.

Unlock your device with a network unlock code

Before you begin: To obtain the unlock codes for your BlackBerry device, contact your service provider.

Your device might be network locked which allows your device to make a mobile network connection with only your current service provider. If you plan to travel internationally and you want to use a SIM card from another service provider, you might need to enter an unlock code.

Tip: To see the current service provider associated with your device, on the home screen, swipe down from the top of the screen. Tap image Settings > About. In the Category drop-down list, tap SIM Card.

  1. On the home screen, swipe down from the top of the screen.
  2. Tap image Settings > Security and Privacy > SIM Card.
  3. In the Phone Network Lock section, tap a locked item.
  4. When prompted, enter the unlock code.

CAUTION: For security reasons, each unlock code can only be entered incorrectly 10 times. If you exceed the number of allowed attempts to enter an unlock code, your SIM card will allow emergency calls only. For assistance, contact your service provider.
