KeyLock – Unlock your PC with a USB drive.

KeyLock is a free, simple solution for protecting your Windows PC with physical access control. Instead of a regular password, the program uses a USB drive as a “key” – and without that key, there is no access to the computer.

It is especially handy for school computers, workstations, or home PCs when you want maximum security without complicated access systems.

Reviewer’s rating with pros and cons, and user ratings

★★★★★

KeyLock is a creative and effective solution for physically securing computers, especially in environments where you want to quickly lock your machine without passwords. It’s a slight drawback that the program is no longer actively updated and that its functionality depends on a physical USB drive — but it’s still useful and unique in its niche.

✅ Pros

🟢 Enhanced security with a physical access key
🟢 Interface is simple and easy to navigate
🟢 Option to personalize the lock screen
🟢 Extra power-saving feature is useful
🟢 Cannot be bypassed with Ctrl+Alt+Del (Task Manager is disabled)

❌ Cons

🔴 Available only on Windows
🔴 Do not lose your USB drive — otherwise you lose access
🔴 The program is no longer actively maintained
🔴 Not suitable as the sole security measure in businesses
