No doubt the remote keyless part is easy to work up because the electric powered lock is already around, but of course you don't see those in houses yet, so the keyless ones are that much farther away.
I'm sure you could get one, but you'd have to find some catalog for the ultra-paranoid home-security nut.
They have several models at ThinkGeek.com. I'm totally saving up for one. Currently you have to touch your access tag (RFID) to the sensor to unlock. But what I really want it to do is detect whether I'm inside or out and unlock it if I'm near the door outside, but not inside. Then there's no fumbling for keyfobs at all.
It's not paranoid, it's just easier. Plus you can do cool things like give out a PIN for friends to get in.
I'm not saying it's paranoid, in and of itself, but that it's most likely marketed to the paranoid.
Whenever I see someone using a keyfob to unlock their car, I always think "I wonder if your insurance will pay when you lose you keys and your car gets stolen."
Why wouldn't it? A car getting stolen is a car getting stolen, unless a family member, you or someone you really conspired to do it with did it.
At least, that's what I've gathered in the line insurance work, reading and classes in Massachusetts.
Well, A, you have to lose your keys like a dummy, and B, it has to be picked up by a bad guy. Call me wacky, but I'd say odds are pretty good that your keys will be found by someone who wouldn't even know what to do with a stolen car.
So it's a small risk vs a medium convenience. Guess I'll take the convenience.
You replying to the insurance bit or your cost/benefit analysis of the decision?
Responding to ericball so the latter.
