Someone pitched me this idea a few months ago and I urged him to pursue it. I'm glad to see that it's being done by a super technical team who seem to know what they're doing. Here's why I'm so excited: 1. Shloosl solves a small but acute problem that nearly everyone in the country has. 2. It's a big FU to a fragmented and unevolving couple billion dollar industry. I don't want to find a locksmith or go to Home Depot…
Security industry? As you said, it's unlikely they'll be surprised. I'd say if it catches on then we're much more likely to see legislation against these sorts of services unless they enforce valid IDs– hell, give it a month and I'm sure someone could find a way to spin it as a DMCA issue. That seems a whole lot easier to them than actually trying to solve the problem, which is that the locks we use are fundamentally insecure.
All in all though I do think it's a great idea, and I hope it does happen. I might even give it a try since I just welcomed a new roommate and it turns out I didn't have as many spare keys as I thought I did...
