Here is a device that allows you to unlock the door via Bluetooth.
Here is a home-brew device built by an electronics enthusiast.
A while ago I heard about this and i really wanted to do it with my house as well.
In terms of security, it is secure as long as you have your phone with you and nobody can hack the signal. You pair with the Bluetooth lock once using a strong password, then on each sync it checks the phones MAC address and Password. This makes it difficult to spoof the key (but a strong password is still important).
