Hello, the following issues need attention:

(1) The key should be locked with screws.

(2) When installing the key sleeve, after the key is aligned with the key hole, press the red sliding sleeve, and then push the inner key clip.

(3) After installing the protective cover, make sure that the inner cover is flat. If the inner cover protrudes, you need to adjust the key and key sleeve.

You can fully insert the key (sometimes you need to push it hard) to unlock it. Remember to remove the key after unlocking.

The anti-theft mode with stick lock prevents thieves from unlocking the technology. The anti-theft mode of stick lock can be enabled through the mobile phone app. In this mode, the key cannot be used to unlock the door. If you want to close this mode, you can close it through the app settings.

If the lock is in anti-theft mode, it should be closed first. Let the locks be unlocked once more, and tear off the locks with a little force (you can drip in oils with strong permeability such as Fengyoujing to weaken the sticky adhesive.).

There may be several situations:

① The anti-theft door lock is old and jammed, which affects the work of the equipment: the lubricant can be applied to the key to insert the lock core and rotate to lubricate until the manual rotation feels smooth. At the same time, the anti-theft door lock tongue is also coated with lubrication, and then use the lock.

② The key in the lock is not installed in place: the metal part of the key to open the door of the key cover is exposed as much as possible, then lock the key, insert the door lock to rotate the test, re-install the lock after normal rotation, and continue the switch lock test.

③ Check whether the lock is installed in an offset position, pull out the protective cover and key sleeve, insert the positioner to check whether it is installed in an offset position, the lock core should be in the positioner hole, and the key hole should be aligned with the positioner horizontal line.

④ Whether the shape of the keyhole is a crooked crescent shape, the shape in the picture cannot be used.

⑤ Whether the keyhole trim is stuck in the key sleeve.

Please follow the installation procedure and installation demo video on your phone to carefully check whether your installation process is correct. Click "No. Calibration" during the test to fine-tune. If it still doesn't work, use a locator to insert it to detect whether it is installed in a deviated position.
