Frequently asked question

The handle I purchased only is “locked” when pushing down to open. If you lift up on the handle at any time it is always unlocked & will open. Help?

Hello dear. Thanks for your inquiry. You made an error during installation. Please find the arrow on the square shaft of the lock and keep the direction of the arrow always facing the latch(opposite the handle). If you have any questions, please contact us.

Under the description it mentions “4 aaa alkaline batteries”. wouldn’t lithium be better for wireless door locks?

Hello dear. Thanks for your inquiry. Lithium batteries can also be used in our wireless door locks, but It is no different from alkaline batteries for smart door locks.

Can it be left unlocked?

Yep. You have to download the TTLock app and you can control it through there. There’s an option in the app to have it stay unlock until whatever time you have put.

How do you know that it is locked from the inside? Is there an indicator?

Dear, sorry to have kept you waiting, this lock cannot be locked from the inside. You can only delete the fingerprint or permission of the specified user through the TTLock APP, I hope my answer can help you

    It is not compatible with Google home even with the g2 gateway. Like it is advertised.

    I can’t use Google home to control it with my voice like it is advertised.

    Meet All Expectations!

    Installation was seemless. No need to down load the app suggested. If you have sifely app already, you can add the door lock to that app.

    Update: Got it working!

    Update: It’s a bit fiddly to set up, but now that I’ve finally got it installed it is working great!
    Things to pay attention to:
    1. There is an arrow printed on the lock shaft- ensure the surface with the arrow is installed perpendicular to (or facing) the strike plate. If you miss this step the door will be locked when you turn the handle on one direction, but not in the other.
    2. Just remove the two screws on the far end of the handle to install the batteries. That allows you to unsnap the battery retainer.
    3. Don’t fail to push the tiny black reset switch after installing the batteries.
    4. Leave the back cover off while you are you are working with the app. This is so you can get to that reset switch again, if necessary.
    5. If you’ve come this far you’re done, right? Wrong! You must yet program the lock. Let the app turn on your bluetooth.
    6. If you’ve programmed in your fingerprints, but the lock opens with touches other than those fingerprints, you’ve got to a. Reset the lock. b. Delete the basic settings. c. Uninstall the app and reinstall it. d. Start over with setting up fingerprints.
    Original post: I would love to know where we went wrong with this lock! We got it installed in the door and programmed in our thumbprints. The door will unlock with those thumbprints, but it will also unlock if we touch the sensor with any other fingerprint, even the heels of our palms! It is, as installed, an extremely ineffective lock. I’d be happy to change this rating if the vendor, or someone else here can guide us to correct our installation.
