Want to make your own Bluetooth Door Lock? Just yank out the stock electronics and toss in some custom electronics along with some code (that you can modify) and you are off to the races.
 “To open the lock, we will use the app LightBlue. It has a section called the Sandbox, that lets you control the LightBlue Bean without having to program your own iOS app. When the LightBlue Bean receives a serial message, it checks the bytes received against the keycode saved inside the sketch. If the keycode matches the buttons pressed in the sandbox, the Bean Lock will unlock or lock. Get the code from GitHub.
Also, remember to add a pincode to your Bean to prevent other people from reprogramming it.”
