Zkteco Ua300 | Factory Reset

To perform a factory reset on a ZKTeco UA300 biometric device, you can use the internal menu if you have administrator access, or utilize "Super Passwords" and hardware tamper switches if you are locked out. Resetting returns the device to its default state, which often includes clearing user data and reverting the IP address to 192.168.1.201. Method 1: Standard Reset via Device Menu

If you have admin access or the device is not locked, follow these steps to restore factory settings: Turn on the ZKTeco UA300

Press and hold the M/OK button for a few seconds to enter the menu. Navigate to Settings (or System). Select Restore Factory Settings (or "Initialize").

Confirm the action. The device will reboot with default configurations. Method 2: Reset Admin Privileges (If Locked Out)

If you cannot enter the menu because of a forgotten admin password, you can use a time-based "Super Password":

Check the Time: Note the exact time displayed on the device screen (e.g., 14:20). Generate a Super Password:

Option A: Use a specialized ZKTeco Password Reset Tool on a PC. Enter the device's time to generate a one-minute temporary password. zkteco ua300 factory reset

When prompted for an ID, enter 8888 and press OK. Enter the Super Password when prompted for the password.

Clear Admin: Once inside the menu, go to System Options > Advanced Options > Clear Admin Privileges to remove the lock. Method 3: Hard Reset via Tamper Switch

For models with a physical tamper switch (located on the back of the device), you can force a reset: Restart the device.

Wait for about 30–60 seconds after it boots until you hear a short beep.

Press the Tamper Switch three times quickly (within 30 seconds of the beep).

Q1: Will a factory reset remove the firmware version?

No. A factory reset only erases user data, logs, and settings. The firmware (operating system) remains the same version.

Q3: Does the device need to be connected to a PC for reset?

No. In 99% of cases, you can reset directly from the touch screen or boot menu.

What if the Engineering Menu doesn’t appear?

Try different tapping rhythms: double-tap rapidly, or tap continuously from the moment power is applied. Some firmware versions require you to press the physical power button (if equipped) while tapping the screen.

8. Conclusion

The ZKTeco UA300 factory reset is a powerful recovery tool but results in complete data loss of users and logs. The menu method is safest when admin access exists. The hardware jumper method is the only way to bypass a lost admin password. Always verify the PCB revision and jumper location before shorting to avoid damage.

  • Philips Head Screwdriver (to open the back casing for hard reset).
  • A paperclip or jumper wire.

  3. While holding the button, power on the device.
  4. Keep holding until you see a menu or a prompt mentioning "Restore Defaults" or "Factory Reset" .
  5. Navigate using the arrow keys to confirm (usually select "Yes").
  6. The device will reboot, returning to default IP (192.168.1.201), default communication credentials (often no password or 12345), and zero users.
