Has anyone ever used this or do you know about it?

Remote control, like a car. Were you pleased? When the batteries get
weak, do you know if the door did not get looked? It uses iirc 4 AA
cells. (With a car, one locks the door when he's finished driving so the
car battery is allways strong.)


What about this push-button combination front door lock?

Any opinions on that? I'd have to lose the key and forget the code to
get locked out


Or what about this one:

that uses my fingerprint to let me in. I can't forget that. But does
the model you have in mind recognize a fingerprint immediately or do I
have to wiggle my finger and wait? (It also takes a key and a
combination.) Again batteries, doesn't say how many. (THIS ONE IS FOR
INDOORS BUT THERE IS PROBABLY ONE FOR OUTDOORS.
