Can you suggest a USB motor / solenoid / actuator that can by activated via the command line on my Windows 8 PC? I would like my front door to automatically unlock every time I approach it. Details are as follows:

I downloaded BTProx for windows
, which is an application that senses when a bluetooth device comes within range (about 30 feet) of the computer. I installed BTProx and paired it wit my smartphone. Now everytime my computer senses my smartphone, the BTProx application will launch a program on my computer.
My front door is within range of my computer's bluetooth sensor, and I successfully have BTProx running a basic command line program that prints the current time, and I would like to find a way to unlock my front door with this setup.
My question to the hive mind is: can you suggest a USB motor / solenoid / actuator that can by activated via the command line on my Windows 8 PC? I'm going to attach the motor / solenoid / actuator to the doorjam to automatically turn the doorknob. My vision for a finalized version of this setup will be: 1. I approach front door. 2. BTProx senses my phone's bluetooth and runs a .bat file that turns on the USB device. 3. The USB device turns the doorknob, then resets itself back to resting position after 10 seconds.
Any suggestions for USB powered devices or other ideas altogether? I'd like to find a device that's simple and cheap.
