If you still have communication between the device and your computer, you do not need a third-party reset tool. You can clear the administrator status directly from the software interface. Using ZKAccess 3.5 or ZKTime Open the software and ensure the device is "Connected." Go to the or Terminal Management tab.

This is set within the management software (like ZKAccess 3.5 or ZKBioSecurity) to prevent unauthorized PC-to-device communication.

Select your device and look for an option labeled or "Cancel Admin."
