To lock the Curve just hold down the Enter/Return key. That works on mine.
you can also download this software:

How to reset the blackberry curve password without losing data We have a BB that was turned in because an employee was terminated and they locked it before turning it in.


No you can't unlock blackberry curve 8300 without losing data if you didn't know the correct password, that's feature of RIM security to secure all customers data if their phone stolen or missing. You must type any password 10 times to unlock blackberry password and there is no option to save all your data.

How to change password on blackberry when you don't know the password?


If you or a user turns on content protection for a BlackBerry device that is running BlackBerry Device Software version 4.3 or later, you can reset the BlackBerry device password using a BlackBerry Enterprise Server version 4.1 SP5 or later. The BlackBerry Enterprise Solution uses the remote password reset cryptographic protocol to reset the BlackBerry device password when content protection is turned on. The BlackBerry device does not prompt the user for the old BlackBerry device password.
The remote password reset cryptographic protocol is designed to provide the following features:

* permit the BlackBerry device to encrypt the content protection key again with the new password, without the old password being available
* prevent a hardware-based attack on the BlackBerry device from recovering the content protection key without knowing either the BlackBerry device password or the IT policy private key that the BlackBerry Enterprise Server generates for the BlackBerry device
* prevent the BlackBerry Enterprise Server from accessing any data that a potentially malicious user could use to recover the content protection key

To reset the BlackBerry device password, you send the Specify new device password and lock device IT administration command to the BlackBerry device. You should send the IT administration command to a content-protected BlackBerry device that is in the possession of the BlackBerry device user only. If you send the IT administration command to a BlackBerry device that is in the possession of a potentially malicious user, that user can use a hardware-based attack to recover the key pair that the BlackBerry device created when it received the IT policy. The potentially malicious user can use the key pair to decrypt all the data on the BlackBerry device.

* Process flow: Resetting a BlackBerry device password when content protection is turned on

Locked out of my blackberry curve 8520 smartphone


If you are locked out you can enter the wrong password several times and the phone will restore to factory settings. The downside to this is you lose everything unless you used the backberry server and saved!

Describe your AT&T BlackBerry Curve


BlackBerry smartphones support individual security passwords between four and 14 characters in length. The use of the password is designed to make sure that only the BlackBerry smartphone user can access the information stored on the BlackBerry smartphone.
The BlackBerry smartphone rejects less secure passwords, such as those composed of identical characters or those that consist of natural sequences (for example, 1234). In instances such as these, the BlackBerry smartphone will display the message The password cannot be a sequence.
Set a BlackBerry smartphone password
  1. From the Home screen of the BlackBerry smartphone, click Options.
  2. Click Security Options.
  3. Click General Settings. Note: If you are running BlackBerry® Device Software 4.0.2 or earlier, click Options, and then Security.
  4. Change the Password field to Enabled.
  5. Display the menu and click Save.
  6. Type your new password and click Enter.
  7. Verify your new password by typing it again and click Enter.

Additional Information When the Security Timeout feature is set for a longer duration than the Backlight Timeout feature, the BlackBerry smartphone will lock automatically when the combined duration of the features has elapsed. For example, if the Backlight Timeout feature is set to dim after two minutes and the Security Timeout feature is set for 20 minutes, the BlackBerry smartphone will not automatically lock until 22 minutes has elapsed.
