Overview

The Cert Update Utility updates the expired security certificate and firmware for SREDKey 2 readers. 

Note the following information:

• Each SREDKey 2 reader requires a separate update due to security certificate information.
• After the utility installs the security certificates, it scans the Firmware directory and completes the update.

Updating a SREDKey 2 Reader

1. Open the Cert Update Utility directory.
2. Plug the target SREDKey 2 reader into the computer's USB port.
3. Run Cert_Update_Utility.exe.
4. The utility prints a successful update message when complete.

When the update is complete, unplug the SREDKey 2 unit and, if needed, plug in the next device to update; the utility can update as many devices as needed.
