Q: Help please!!!

Hi, brianna_1.  

Thank you for visiting Apple Support Communities.  

I understand that your iPhone is disabled and your Sleep/Wake button is also not working.  I have a couple solutions that may get your device functioning again.  If you have the Find my iPhone feature enabled on your device, you can wipe it by using iCloud.  Take a look at the article below for more information.  

Erase your device with iCloud

If you set up Find My iPhone on your iOS device or Mac, you can use iCloud to erase and restore it.

1. From another device, go to icloud.com/find.
2. If prompted, sign in with your Apple ID.
3. Click All Devices at the top of your browser window. 
4. Select the device you want to erase.
5. Click Erase [device] to erase your device and its passcode.
6. Now you can either restore from a backup or set up as new.

If your device isn't connected to a Wi-Fi or cellular network, you can't erase it with Find My iPhone.

 

If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled

The next option would be to take a look at your Sleep/Wake button since you have an iPhone 5.  Take a look at the information in the link below to see if your device qualifies.
