Kwikset Kevo Bluetooth Electronic Lock: No more fumbling for your keys with the Kwikset Kevo electronic lock. Its Bluetooth connectivity automatically syncs your mobile device to your lock with touch-to-open convenience, making your smartphone or tablet your new key. Use the Kevo app to grant access to others and track their usage.
I like that you can finally remotely lock this but you still have to buy another device to do it. Also if you accidentally bump the lock on your way out the door it will lock at times unintentional. You think they could figure out if the door was open or closed first.
