Teodoor Smart Door Lock
Teodoor can automatically open your door when your phone is near via Bluetooth as well as grant temporary access to other people. But unlike most of its competitors, Teodoor also lets you use your existing keys and turn your lock manually.
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
