I recently installed a U400 t replace my Eufy lock that was driving me crazy. It’s been working great, except for today, I exited the door and it automatically locked behind me after a minute. I tried opening the door with my fingerprint and PIN code, neither worked. The lock made some noise and would not unlock. After numerous attempts it opened. I see the following error code in the log, “Latch not fully extended or retracted.” The latch mechanism work’s smoothly and does not have any issues with the alignment of the door or striker plate. Calibation works flawlessly. Any ideas on what and how do I prevent it from reoccurring and being locked out?
Thanks Shane
