I think the costs are prohibitive. I can see this at around $300+ (hardware, installation). Considering most people buy locksets under $30, it's not hard to imagine why noone's pushing this in the marketplace.
i agree on existing houses. if you wanted you could probably hollow out your door frame and add an actuator build for a car, but that would be pretty expensive and a big pain in the ass. on a new house on the other hand, $300 for keyless entry probably wouldn't even add $1 to your mortgage. and, once it is the rage there, others would be jealous and spring for the $300.
i think it is just up to someone to position it and market it correctly for it to be the next big thing. ten years ago you probably would have scoffed at the idea of paying extra for keyless on your car, but now most people wouldn't buy one without it.
i don't think i would really be into the finger print scanner thing, though. it has been noted far too often on tv and in the movies that you don't actually need the person or even their whole hand to get past a finger print scanner. same with eyes.
