I came across this project by some university students for the TI Ultra low power challenge.
They have used a special wrist watch which contains a TI ZigBee wireless device and accelerometers. They send the unlock code by tapping on the wrist, this tapping is interpreted by the accelerometer, then encrypted by the ZigBee device and transmitted. Another ZigBee device is present inside the door lock, which decodes the encrypted unlock code sent by the watch and then activates the servo to open the lock.
And the fun part is that he opens the door from about 20 meters away and the time taken is less than it would take to get a key out of ones pocket and open the door with it!!!
Here is the video of the demonstration.
