Would you please specify the issue? Did you mean that it does not turn on/respond or it was disabled because you have entered wrong passcode?

If it does not respond/ does not turn on:

Force your device to start. To do this, press Sleep/Wake and Home buttons and hold them for at least 10 seconds.

Try to reset your device. This won't delete your data stored on the phone.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

If this does not help, take a look these Apple Support articles:

If it was disabled after wrong passcode: Forgot passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

If it was disabled follow the instructions on this page: Forgot passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support
