Lock screen is gone

[LTomBerry]

My phone just started doing this a few weeks ago. I don't know if I accidentally changed an option or if it's got a mind of its own. The lock screen no longer comes up when I turn the screen on. It just goes straight to the home screen. It doesn't matter whether I turn the screen off myself or from inactivity. This has resulted in a couple of butt dials and other goofs. Any ideas how to get it back? Running stock Verizon W6.5
