At least in my experience people are a lot more likely to leave the garage door unlocked than the front door, either intentionally or unintentionally.

Agreed. Our garages have always had three entries: one from the house, one via garage door, and a side door. Side door was always locked, garage door always closed (never locked though), and the door between house and garage not only almost never locked, but often flat out open because that's where we put the litter box.

haha, our litter box is there as well. vinyl floors in mudroom are easiest to clean.
