We have SimpliSafe keypad locks and I believe you can use the key if you need to. My daughter installed UltraLoq U-Bolt locks, which also let you use a key.
I like the fact that I can give guests, our cleaning lady, some service folks their own codes and can eliminate their codes when their need to use it goes away. We gave three driveway facing doors and I have locks on all three and like the fact that I can lock or unlock them when traveling and can see when people lock or unlock the door.
I’m a little unclear on how secure things actually are. We live in a very safe sub/exurb at the very end of a 1/2 mile street – only house on a cul-de-sac and you can’t see our house from the street. People would pass a number of very large, expensive looking houses visible from the street prior to reaching the cul-de-sac. And on the other side of our house is a river. But, because it is on the river, the house is mostly glass and actually has 13 external doors (Mostly sliding doors). We do lock the door at night and when we go out at night but mostly don’t activate the alarm system.
