Making a Universal Serial Bus (USB) security key requires installing a software program, such as Desktop USB Security Key, ID USB Lock Key or USB Lock Pro on a USB flash drive. This will enable you to lock and unlock your desktop or laptop computer by simply removing and inserting the USB flash drive into a USB port. However, you will first need to obtain a USB flash drive to use for the security key.
