Hi LinkdaKR and welcome to the BlackBerry Support Community Forums!
Are you referring to the keyboard lock or the password lock on your BlackBerry® smartphone?

The lock button on the top left hand side of the phone. I believe it's the keyboard lock. The screen turns black and is locked until I press it again. It used to keep me from accidentally pocket dialing when I'm finished with the phone.

Which version of software did you upgrade your BlackBerry® smartphone to? If you're not sure, you can type 'myver' in any text field then press the space key to display it.

Can you try downgrading your BlackBerry smartphone to the previous version to test it for me?
Plug your BlackBerry smartphone into your PC then launch the BlackBerry Desktop Software. Before doing anything, backup your device. Next, click on Device then Update. Choose View Other Versions from the pop up screen then choose 220.127.116.111 from the list.
If you could try this when you have the opportunity, then let me know if the lock button works, it will help in diagnosing whether its a software bug or a physical problem with the device. You can just let me know the results.
