Q2: Will Tapo Smart Locks Lock Automatically After I Unlock It?

You can enable the Auto Lock feature in case you forget to lock the door. You can also set a Disable Auto Lock schedule to disable auto lock within a set time. To enable the Auto Lock feature, go to Device Settings > Lock Settings > Auto Lock.

Here is how auto lock works:

When the door sensor is available (requires installation and calibration):

• Auto-Lock after Closing: When you enter or leave and close the door, the system detects the "Closed" status and starts the timer to lock automatically.
• Smart Trigger: If no door opening is detected after unlocking, the timer won’t start right away. This prevents the door from relocking before you have a chance to walk through.
• Safety Backup: For added security, if no door opening is detected within 5 minutes after unlocking, the system will automatically relock the door to ensure your home stays secure.

When the door sensor is unavailable:

• Timer-based locking: The countdown starts immediately after successful unlocking, and the lock will engage when the countdown ends.

Mode switching:

• If the door sensor becomes unavailable while Auto-Lock is enabled, the system will automatically switch to the timer-based mode, ensuring the features continue to work as intended.

Q3: How Can I Change My Existing Password?

You cannot edit an existing password directly in the Tapo app, but you can create a new password and delete the old one. To learn how to add a new password, please refer to the following guide.

Q4: Can I Still Control The Tapo Smart Lock If The Router's Wi-Fi Suddenly Doesn't Work?

Yes, if the router’s Wi-Fi goes down, you can still connect to the Tapo Smart Lock via Bluetooth when you are next to the device.

Q5: What Is Wrong-Try Protection?

Wrong-Try Protection is a security feature of Tapo Smart Lock with fingerprint capability. When the failed fingerprint attempts reach the limit you set, you can use the PIN code to unlock. If the limit of PIN code attempts is reached, both methods will be in lockdown for the time you set. You can enable this feature in the Tapo app under Device Settings > Security Settings > Wrong-Try Protection.

Q6: How Does Scramble Pin Code Work?

With the Scramble PIN Code feature enabled, you can enter decoy digits before and after your passcode to prevent others from snooping your actual access password. Using a Scramble PIN Code makes your actual password longer, making it harder for others to remember. The total length should be no more than 20 digits. To set the Scramble PIN Code, go to Device Settings > Security Settings > Scramble PIN Code.

Q7: How to Check the Smart Lock Event Log

You can view locking, unlocking, and other activity on the door lock via the Event Log on the Status page. Tap Event Log on the Status page. If you want to save the log to the Cloud, you can enable Log Backup.

Door Sensor Related

Q1: What’s the difference between Door Sensor Calibration and Lock Calibration, and how can I do that?

Lock Calibration teaches the lock the orientation of your door and the exact limits of its locked and unlocked positions

To calibrate the lock, go to the Tapo app > Tap the Lock > Tap the Settings icon ( at the top-right corner) > Tap Lock Calibration.

On smart locks with a built-in Door Sensor, the calibration function teaches the lock the exact spatial relationship between the door frame and the door itself.

To calibrate the Door Sensor, go to the Tapo app > Tap the Lock > Tap the Settings icon( at the top-right corner) > Door Sensor > Tap Calibrate.

Q2: What should I do if the door sensor calibration fails?

The optimal placement for the door sensor is 7–10 cm from the center of the interior assembly. If calibration fails, please readjust the position of the Door Sensor.

Q3: Compared with door locks not equipped with a Door Sensor, what additional functions do those fitted with a Door Sensor have?

Left Open Alarm: When the door is open for a long time, the Tapo DL130 will notify with a phone notification or hub alarm.

Auto Lock with Door Closed: All Tapo door locks support automatic locking and will automatically lock after the countdown ends. For door locks with door sensors, the countdown only starts after the door is actually locked. For door locks without door sensors, the countdown starts as soon as the door is unlocked.

Door Opened/Door Closed Status as the Smart Action trigger: Door sensors can detect whether a door is locked or unlocked, and therefore can be used as triggers for smart actions.

Q4: Do I need to replace the battery for the Door Sensor?

There’s no need to worry about the door sensor’s battery, as it will use the battery of Tapo DL130.
