Remote locking is quite common for automobiles, not so common for doors. This James Bond-ish home security system uses a coded signal from the wristwatch to the electronic box on the door to lock and unlock the door. Far more stylish than a few RFID locks we’ve seen in the past.

The code is a 128-Bit encrypted signal that is generated by tapping the screen of a geek-tastic TI Chronos watch containing a micro-controller, accelerometer, and Wi-Fi.

The accelerometer picks up the sequence of taps on the screen and relays it via Wi-Fi to the electronic system attached to the door bolt. The door system decrypts the tapped signal and actuates a servo to locks/unlock the door. Check out all the details and links to the source code.
