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.

A related option to allow entry based on a code, if you don't want to replace your lock, is to put a combination key lock box (sometimes called a "realtor box") somewhere near the door. We have one of these and have been very happy with it. And no batteries that can die!

One threat model with that kind of approach is that once a visitor possesses your key -- even if they return it -- you can't tell how many copies they may have made.
