App that lock the phone with volume button

[AC Question]

Hello, i have a samsung galaxy s3, and lately my power button was having issues and it locked my phone on the reboot screen, So i removed it and now i dont have a power button. And i found apps that lock the phone from the screen, but most of them are annoying and drain the battery. Is there any app that let me lock the phone using any alternative button, like volume up/down?
