The ZKTeco UA300 is a biometric time and attendance terminal. Factory resetting the device is typically done to clear the database, reset communication settings, or remove an administrator who is no longer available.
Method 1: Reset via the Device Menu (If Admin access is available)
If you can still access the menu, this is the safest and most complete method. Press the M/OK key to enter the main menu. Navigate to System and press OK.
Select Auto Test or Advanced Settings (the name varies by firmware version). Find and select Factory Reset.
Confirm the action. The device will reboot with default settings. Method 2: Reset Admin Privileges (If locked out)
If you are locked out because of a forgotten administrator password or fingerprint, you can use a temporary "Backdoor" password based on the device's internal time. zkteco ua300 factory reset
Note the Time: Look at the current time displayed on the UA300 screen (e.g., 14:20).
Generate Password: Use the ZKTeco Admin Password Reset Tool or a similar utility. You enter the device time, and it generates a one-time password. Enter Backdoor: Press M/OK. When prompted for the Admin ID, enter 8888. Press OK and enter the generated temporary password.
Clear Admin: Once in the menu, go to User Management, find the administrator, and change their role to "Normal User" or delete them entirely. Method 3: Reset via Management Software
If the device is connected to a network, you can reset it using ZKTeco ZKTime.Net or similar management software.
Open the software and ensure the device status is Connected. Go to the Device Management or Terminal Management tab. Look for AC Manage or Device Maintenance. Select Clear Admin Privileges or Restore Factory Settings. Default Connection Settings
After a successful factory reset, the device will return to these defaults: IP Address: 192.168.1.201 Subnet Mask: 255.255.255.0 Gateway: 0.0.0.0 Admin Password: None (or 1234 for some older variants) To help you further, could you tell me: Are you locked out of the admin menu? Do you have the ZKTeco software installed on a PC?
Where the "Factory Reset" experience loses points is in the nuance of what actually gets erased.
