IPhone 5 home and lock buttons unresponsive?

IPhone 5 home and lock buttons unresponsive?

Added (1). i replaced the battery on my phone by myself (i have done it before with my other iPhone 5) and after reassembling, my phone was stuck in a recovery mode loop. I fixed that problem, but then i realized the home and lock buttons were unresponsive. I thought i had pry damage on it from taking out the battery, so i reopened it and i found nothing out of the ordinary to me. The funny thing is, my volume down button used to not work and now it does, even though my home and lock button doesn't.
