I installed a dead bolt on the door from my house into the garage with the key side in the house and the lever/knob side in the garage. The solid core fire rated door opens into the house and can't be kicked open from the house side. Simply walk through the door turn the dead bolt latch and pull the power cord to the garage door opener. (no one can use the door opener from the vehicle outside to open the overhead door) Loaded 12 ga and cell phone hidden out there as well as a stocked fridge. The family likes the simple safety option.
