Tapo DL110 Calibration Failed
I recently installed the Tapo DL110 and am getting an error when calibrating. I can verify that the lock itself is working and the doorbell and touchpad both work. I have reset multiple times and removed and replaced the battery with no change,

Do you use the new bolt provided in the package, or the old one? If you're currently using the old one, try to install the new one, see how it works.
Does the lock turn smoothly when you operate it manually with the thumb latch on the door lock? Any noticeable interruption?

@Wayne-TP I used the new bolt from the package. The old bolt wasn't compatible. The lock turns smoothly (no resistance) and I've tested with both the door closed and open.

@Wayne-TP hello, I am having the exact same problem and am currently unable to use my lock. Can I get some assistance?

@SoosFetti I ended up having to return mine to Amazon. I bought it used and I wonder if they keep repackaging these broken locks as "used".

Regarding the calibration failure issue on Tapo smart door lock, here are some troubleshooting suggestions:
1. Go through the installation video again to make sure every step was done correctly. How to Install Your Tapo Smart Wi-Fi Door Lock (Tapo DL100 / DLW10)
2. If you’re still using the original lock bolt, please replace it with the bolt included with the product, then try running the device again.
3. If the new bolt is already installed, make sure you can lock/unlock the door smoothly by hand. If not, dissemble the lock and reinstall it, making sure the tailpiece is mounted vertically, not tilted.
4. If the lock can be manually locked and unlocked smoothly but calibration still fails, please verify the calibration results separately with the door open and with the door closed.
a. If it calibrates when open but fails when closed, this indicates that the door frame depth is less than the length of the lock bolt when fully extended. Use the included Strike Box to adjust the frame depth for proper fit.
b. If calibration fails in both positions, this isn’t typical. In this case, please reach out to our support team for further assistance.

*Please perform a calibration with the door open and another with the door closed, and record a video of each. We’d recommend filming from inside the room, capturing the lock turning and the latch moving. Then share the videos with the support team for analysis.

I just purchased the Tapo 100 and I cannot get past the calibration. I am using the lock plates that came with the unit. The calibration even fails with the door open. I twist and turn the lock back and forth and there is no resistance. I even reset the lock and set it up again but it got stuck at the same step. Should I return it?

Is the deadbolt you’re using also the one that came with the product? I’d suggest going through the installation video again to make sure every step was done correctly. How to Install Your Tapo Smart Wi-Fi Door Lock (Tapo DL100 / DLW10)
For example, check whether the deadbolt is installed level and properly aligned.

If you still haven’t noticed anything unusual, please refer to the info in #7 and contact our support team with the relevant details so they can follow up further.
