MetroKey (COM4) Driver

The MetroKey (COM4) driver helps Windows communicate with the Metrologic USB device listed as MetroKey on the COM4 serial port. It is intended for users setting up the device, restoring a missing connection, or troubleshooting software that cannot access its assigned COM port.

Key Features

• USB device communication: Provides the driver support Windows needs to recognize and communicate with the connected MetroKey device.
• COM port access: Enables compatible applications to use the device through its assigned serial interface. Although the device name shows COM4, Windows may assign a different port after installation.
• Support for older Windows systems: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that explicitly supports your Windows release and system architecture.
• Connection troubleshooting: Installing the correct driver may resolve recognition problems caused by a missing, incompatible, or damaged driver.

How to Install MetroKey (COM4) Driver

1. Check your Windows version and architecture. Confirm whether your system is 32-bit or 64-bit before selecting a package. If comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supplied support list; do not assume compatibility.
2. Verify the device identity. Open Device Manager and locate MetroKey (COM4), or check unidentified USB devices. Compare its hardware IDs with the driver package information where available.
3. Choose the appropriate download. Before starting your MetroKey (COM4) driver download for Windows, confirm the package supports your device and operating system. Use a trusted source, and check any free download for authenticity rather than relying on its filename alone.
4. Install the driver. Extract the downloaded archive if needed. Run the included installer and follow its instructions, or select Update driver in Device Manager and browse to the extracted driver folder.
5. Confirm the connection. Restart Windows if prompted, then reconnect the device. Check Device Manager for warnings and confirm the assigned COM port. Configure your application to use that same port.

Keep the driver updated when a compatible release addresses a problem or meets your software requirements. Before an update, verify that the latest version still supports your Windows release and MetroKey hardware. If the device already works reliably, review the release notes before replacing its current driver.
