I tried using my USB Wireless Lock again the other day, but it's just too dammed flaky. My PC would lock it self randomly even when my FOB was close by.

Then I came across this post on lifehacker about a program called Blue Lock that will use your Bluetooth phone and Lock once the phone is outside of the visibility of your PC.

I've been running it for a few days and it works flawlessly. So well in fact that sometimes it won't lock if I am around the corner because the range of bluetooth can be pretty substantial.

The program works best when your machine is using the Microsoft Bluetooth Stack. I have a Microsoft Laser Mouse 8000, which of course uses the MS Stack. But my Lenovo Thinkpad uses the Broadcomm stack (you can still use the MS one if you uninstall the Lenovo software).

Quick note. If you want your machine to automatically lock again after you unlock your PC (it doesn't do this) you need to go into the configuration file in the bluelock folder and change:

clearLockDeviceFieldOnLock=true

to false:

clearLockDeviceFieldOnLock=false

and definitely pay attention to the warning. I set my timeout to 30 seconds.
