I know smartlocks have had their share of vulerabilities. I remember 3 or 4 years ago hearing about things such as sending codes un-encrypted over wifi or basing their security on MAC addresses alone. Both are practically a ‘key on top of the doormat’ travesty. THis may have got better. I think the issue is that manufacturers jump at a market without having much knowledge of IT security. Similar to whats happening with the connectivity of cars. The fact that most peeps in IT security(ok, they might lean towards the paranoid) will not have a smart lock on their house is enough for me for the time being.
