If for some reason the average notebook lock is too complicated for you to operate (read: insert key and twist), perhaps the Kensington ClickSafe might be able to simplify matters a little more for you. The ClickSafe system fastens a small locking nub into a notebook’s lock slot and once that is fastened in place, you just need to push the locking cable into that, and your notebook is secured. Of course, you’ll still need the key to unlock it before you take the notebook home, but you already knew that, right? The ClickSafe lock will set you back $49.99 or $69.99, depending on which model you choose. In case you still don’t understand how this fancy new lock works, check out an installation video after the jump.
