We have a non-networked, non-remote electronic combo lock for our front door.

We are never locked out. There is no key under a rock. The phone cannot get unpaired, the remote cannot be intercepted and replayed. If we are on vacation, we can call up a friend and tell them a code so they can get in.

A 9V battery lasts about three years, then it starts flashing and beeping every time you open the door for a month before dying. If you already have the right hole in the door, it takes about 20 minutes to install.

And if you're intent on breaking in, well, the windows are made of glass. Please don't do that.

But did you look at the program code of it? Did you figure out that 8675309 opens it even if you didn't program it? That's what I have worried about on these kinds of devices.

While there is always a chance a backdoor like that exists, and thieves start memorizing default and backdoor codes and also learn how to recognize the corresponding models by sight from a non-suspicious distance... there's an orders-of-magnitde greater chance they use a low skill rock-through-window style attack.
