I never carry a house key.


The one caution I will offer is that you need to be very accurate with the
placement of your strike plates. While the human hand is very capable of
forcing the deadbolt past a strike plate that is slightly out of alignment,
the electronic lock doesn't have that strength and will balk when it
encounters resistance.


I do carry a key. It is in my bill fold someplace. I haven't ever
used it, but in the unlikely case that the batteries go dead all the
doors at the same time I will be able to get in. Just one more
case of belt and suspenders.

Better locks have terminals for jumper cables. You just pull the car
close to the door and hook up the cables and unlock.
