The BusKill App is super easy to use. It works on Windows, Mac, and Linux. It will automatically turn on screen lock when any USB device is removed. The trade off here is simplicity. There is only one action taken (screenlock) and it can not be customized for specific USB devices (triggers on any). But if those limitations seem OK, then the BusKill App is easy to get going.

Here is the main page for the project:

The code is open source and the GitHub repo is here:


Installation and usage of the BusKill App software is covered here:

Follow those instruction to install the BusKill App on to your system.


Once the BusKill App software is installed, usage is very simple.

Launch the BusKill App to bring up the little app window with the arm/disarm button.

Plug in the Neo Trinkey to a USB port.

Click the ARM button to enable the screen lock. The button will turn RED.

Now when the Neo Trinkey is removed from the USB port, the screen lock should be activated.

Note that the screen lock is nothing special - it is just whatever OS specific screen lock you have in place. So it's up to you to configure the screen lock to have password protection, etc.
