Hi David, different homes definitely have different needs and deadbolts come in different styles – both interior turn-lock (single cylinder) and key-lock (double cylinder) depending on the presence of a window near your door. We don’t have a window pane next to our door, so our previous builder-installed deadbolt didn’t require a key from the inside either. Sorry if there was something in this post that implied it was double cylinder/had an interior key, that definitely wasn’t my intention as it’s a keyless lock.

Thank you! We are loving it on the garage so much! Plusn someone else was at our house last week, and I noticed after she left, she forgot to lock the front door. I locked it right from my phone! So handy!
