So usually when my iphone would stop working I would just press down on the lock and home button, and then the Apple logo would appear.
However, my lock button stopped working a while ago..
If I go to the Apple store can I get them to fix my lock button, without deleting any of my phone content?
Apple will not fix the lock button, they will replace the phone for $149. You should back up your phone so you can restore its content to the replacement. If it doesn't show up in iTunes, hope you have a previous backup on your computer or iCloud.
