Kids can be pretty resourceful creatures and there are not many ways of stopping them from doing who knows what on the PC. That is until KidSafe came along, a USB key that is exactly that a key for your PC.

Computer geeks and white-hat hackers in the UK developed the KidSafe Parental Control Key to help lock down computer access in the easiest and most secure way possible. Each key is unique and cannot be duplicated. When inserted, the key allows your computer to boot and access the internet. When removed, the computer is locked tight, and unusable.

Kids today are smart, and can get around Windows passwords, and Internet filtering programs pretty easily. Proxies and workarounds exist for even the most draconian firewalls, but the KidSafe key protects your computer and your kids with a physical key. It’s stronger, more reliable, and more convenient than passwords. It can’t be uninstalled or worked around – even by booting to safe-mode. They’ve even got processes to keep your computer from booting to a live CD or other boot device.

You can buy the KidSafe security key from Think Geek for $59.99.
