Once you've installed the software as described in Installation, you're ready to use LaCie PC/Mac Lock. Simply register a LaCie USB key with the software, and you can use it to lock your operating system just like you lock your front door.

1. Click the LaCie PC/Mac Lock icon in the menu bar (Mac) or right-click the LaCie PC/Mac Lock icon in the system tray (Windows).

2. In the menu that opens, select Configure.
   
3. The Register a key wizard will open. Click Next.
   
4. The next screen instructs you to connect a USB key in order to register it with the software. If the key is already connected, dismount it as described in Unmounting Your USB Key. Then reconnect it.
   
5. In the next screen, type your operating system administrator password (see Assigning an Administrator Password for details).
   
   
   Mac users need to type their admin username and password again in order to finish configuration.
   
6. Once the password is accepted, configuration is complete.

Once you've configured a key, locking or unlocking your operating system is as easy as connecting or disconnecting the USB key.

Please note that you should properly unmount your key as described in Unmounting Your USB Key in order to avoid damaging its file system.

To disable or enable the software, select Disable or Enable in the PC/Mac Lock menu. If you've disabled the software, connecting or disconnecting the USB key will subsequently have no special effect until the software is enabled.

In certain situations, you may wish to temporarily disable the software, such as if you need the USB key or port for another task. To do this, select Disable for 30 minutes in the PC/Mac Lock menu.

If you want to register a different key, you first need to unregister the original key. To do this, select Unregister key in the PC/Mac Lock menu.

You can then register a new key.
