These new key cases can lock your computer automatically when you walk away. For those who tend to leave their computer unattended, this useful device can easily solve the hassle of manually turning it off. The Gatekeeper Chain Key has a built-in proximity sensor that automatically locks your PC when you walk away and then unlocks it when you return to your desk.

This device connects through Bluetooth 4.0 that communicates with your computer. It will give you a peace of mind knowing that your computer is safe from being hacked. Each unique key is assigned to a specific computer, so it can lock and unlock it every time.
