CleanLock

A small AutoHotkey v2 tool with a GUI that locks your keyboard and mouse independently, so you can wipe them down while your PC stays on.

Because you can lock one device and keep the other free, each device can unlock the other with a macro.

Features

• Separate lock buttons for keyboard and mouse
• 3-second delay after clicking, so you can get your hands ready
• Cross-device unlock macros (no need to touch the locked device)
• Safety auto-unlock timer (default 120 seconds, set to 0 to disable)
• Live status display and button labels
• Closing the window always releases both locks

Requirements

• Windows
• AutoHotkey v2
• Running as administrator is recommended for best results

Usage

1. Install AutoHotkey v2.
2. Download cleanlock.ahk and double-click it (or right-click and choose Run as administrator).
3. Click Lock KEYBOARD or Lock MOUSE. Locking starts after 3 seconds.
4. Clean your device, then unlock using the macros below.

Unlock macros

Locked device	How to unlock	Notes
Keyboard	Triple right-click (within ~1.2 s), or click the GUI button	Mouse must be unlocked
Mouse	Ctrl + Alt + M	Keyboard must be unlocked
Both	Wait for the safety timer, or press Ctrl + Alt + Del	Emergency exit

Tip: Avoid locking both at once. If you do, the safety auto-unlock timer is your way out, so leave it enabled.

Limitations

• Ctrl + Alt + Del and Win + L cannot be blocked by any script.
• Some touchpads and gaming mice with their own drivers may not be fully blocked.
• Physical power buttons and laptop lid switches are not affected.
• Windows may restrict input hooks in some elevated apps unless CleanLock runs as administrator.

Cleaning safety

Dampen your cloth rather than spraying liquid directly onto keys or the screen.

Troubleshooting

• Script won't start: Make sure it opens with AutoHotkey v2, not v1.
• Syntax or "Missing quote" errors: Save the file as UTF-8 and make sure it uses straight quotes ("), not curly ones.
• Lock doesn't seem to work: Run as administrator.
