To all of you extolling the virtues of combo locks, I guess you live in pretty secluded houses in safe neighborhoods with zero visibility of the keypad from across the street.

If I had a combo lock, I'd be more worried about someone with binoculars or an ultra-zoom camera watching me key my lock without covering my hand than my physical key getting lost or stolen.

If someone cared that much about getting into my house, they could easily get into any key-based lock as well, or through any other way, like a window.

I live right outside downtown Seattle but I have a fence, so my door is not visible from the street. I don’t know why more people don’t try it.

Aren't the keys you press visibly different from the others after a while? This is a failure mode I've noticed on several code pads. Even though you don't know the exact code, it gives the numbers so you now only have to guess the order.

Just change the code?
