How do I fix my lock button on my iPhone at the top?????
It's amazing how people ask vague questions and expect mind readers to know what's going on. You would think that the Make Use Of forums are filled with psychics.
However, since I'm not a psychic and I'm not sure what's going on, the next best thing is to check out this article from MacWorld UK: http://www.macworld.co.uk/how-to/iphone/how-fix-broken-iphone-lock-button-power-buttons-stopped-working-3464222/
What's the problem with it? Is it stuck, broken, moving but not locking?
