Introducing Lockitron, the Keyless entry using your phone (iPhone).
This is quite an interesting gadget.

Yes, even though the video below shows Lockitron being controlled with and iPhone, the company offers an Android app for Lockitron.
Lockitron is compatible with most through-hole / cylindrical deadbolts (green checkmark). If you have an interconnected deadbolt (yellow X) you can use Lockitron by removing the interconnecting plate first. If you have a mortise lock (red X) then you can install Lockitron above your current lock by adding an additional deadbolt.
