What can I do if latch of the Sifely E Smart Lock (Deadbolt) will not fully retract or fully extend?

Question:

What can I do if the Sifely E Smart Lock (Deadbolt) latch will not fully retract or fully extend?

Answer:

This requires reinstalling the lock. The problem is most likely related to the spindle's orientation or the Calibration Switch. 

• If the door opens on the Left side (facing it from the outside), the spindle (shaft) must be inserted in a straight verticle or orientation into the latch hole.
• If the door opens on the right side (facing from the outside), the spindle (shaft) must be inserted in a straight horizontal orientation into the latch hole. 
• The latch hole must always be at a  square orientation, not an angled or diamond orientation.
