Top Alternatives to Keyboard Locker for Secure Input ControlWhen you need to temporarily disable keyboard input—whether to prevent accidental typing, secure a kiosk, or protect a system while performing maintenance—Keyboard Locker (a lightweight AutoHotkey-based tool) is a popular choice. But it’s not the only option. This article examines robust alternatives, compares their features, and helps you choose the best tool for your use case: personal use, kiosks/public terminals, accessibility needs, or enterprise deployments.
Why consider alternatives?
Keyboard Locker is simple and effective, but it has limitations: it’s Windows-only, depends on AutoHotkey scripting, and offers basic functionality without advanced access controls, logging, or remote management. Alternatives can provide cross-platform support, stronger security, richer configuration, and integration with enterprise tools.
Key criteria for evaluating alternatives
- Platform support (Windows, macOS, Linux)
- Lock granularity (global, per-application, timed)
- Ease of activation (hotkeys, GUI, command-line, remote)
- Security features (password protection, process protection, signed binaries)
- Integration and management (remote deployment, logging, APIs)
- Accessibility considerations (screen reader compatibility, easy unlocking)
- Cost and licensing (free, open-source, commercial)

| Security | System-level control | Needs root privileges |
Best for: System administrators or developers managing kiosks or specialized Linux workstations.
6. macOS: Karabiner-Elements & Accessibility APIs
Overview: macOS lacks many off-the-shelf keyboard-lock apps, but Karabiner-Elements enables key remapping and disabling. Developers can use Accessibility APIs to manage input for specific apps.
Pros and cons:
| Feature | Pros | Cons |
|---|---|---|
| Platform | macOS | macOS-only |
| Granularity | Remap/disable keys, per-device rules | Not a single “lock keyboard” button |
| Activation | Profiles, command-line | May require restarting driver |
| Security | Uses system drivers | Can be complex for non-technical users |
Best for: Power users and sysadmins on macOS who need fine-grained key control.
7. AutoHotkey (advanced scripts) — beyond Keyboard Locker

Implementation examples (short)
- Quick user scenario (Windows): Install KeyFreeze, set a password, use the one-click lock when handing your device to a child.
- Admin scenario (Linux kiosk): Create a systemd service that runs an xinput script to disable internal keyboard and enable an external admin hotkey device.
- Enterprise scenario: Configure a kiosk profile in KioWare and deploy via your endpoint manager; enable remote unlock and auditing.
Security and accessibility considerations
- Ensure unlock methods are accessible (provide alternative input methods for users with disabilities).
- Avoid solutions that can permanently lock out administrators—test scripts on non-production machines.
- Use signed binaries or centrally managed policies in enterprise environments to prevent tampering.
Conclusion
There’s no one-size-fits-all replacement for Keyboard Locker; the best alternative depends on platform, required granularity, and whether you need enterprise controls or a simple local lock. For casual users, Kid-Key-Lock or KeyFreeze work well. For power users and admins, AutoHotkey scripts, BlockInput wrappers, or platform-native tools (xinput, Karabiner) provide fine-grained control. For kiosks and large deployments, invest in commercial kiosk software or endpoint management for security, logging, and centralized control.
