One of the strong design features of Apple's iPhone, going right back to the first launch in 2007, is that the handset has only two buttons and two switches with all the other functions controlled from the touch screen. It's the two buttons that are important for controlling the locking function, the "Home" button and the "Sleep/Wake" button. You can use them to try and solve a problem with your phone's locking function. If that doesn't work you should take the phone for repair.

Press the "Sleep/Wake" button, the one on the top side of the phone. Now drag the slider and your phone should come on.
Press the "Home" button, the one near the bottom of the phone's front. Drag the slider that appears.
Press and hold down the "Home" button until a red slider appears. Drag this to turn the phone completely off. Now press the "Home" button again, until an Apple logo appears on the screen.
Press and hold both the "Sleep/Wake" and "Home" buttons for 10 seconds. An Apple logo should appear as your phone powers up.
If you're still having problems with your phone's locking function, you can take it to an Apple Store or an Apple-authorised service provider. They'll repair it for free if it's still under Apple's one-year warranty, but there is likely to be a charge if your phone is out of warranty.
