Teodoor Smart Door Lock paired with the bluetooth on your phone is your new door key. Taking your house to the ultimate next level – you can set it to automatically unlock your door when you’re in close proximity and then lock behind you. The companion app helps you set permissions for other people based on one time or recurring as well as lets you open your door remotely. Another part about this that I really like is that you can still use your regular key as needed. Say for your parents who will never join the smart home movement or when you forgot to replace the batteries. You can back Teodoor on Kickstarter for $119 and get it in silver, black or gold.
