U200 Lock Jamming
Hi all. I'm having an issue with my U200 lock after it being replaced for the same issue - and was wondering whether anybody was having the same problem - being a little wary of the same issue happening with two locks.
It is currently calibrated and set to auto lock when the door is shut - this all works fine. However, we tend to unlock the door manually both from the inside knob and the outside via our key. After working fine for months originally (although the replacement barely lasted a couple of months before showing up this issue), I was finding that after the lock automatically locked itself, it had a huge amount of resistance when trying to unlock it via the knob or key, making it a real struggle to unlock the door manually.
This issue did not occur if we locked the lock manually - only when it locked automatically. And we re-calibrated both locks, reset them, re-calibrated, all to no avail.
Confusingly, unlocking it manually from the inside - it appears you can sometimes get it unlock manually normally if you turn the lock the other way first - the U200 almost slightly clicks when you do this (I can confirm that this feeling is from the Aqara unit, and not the actual lock in the door). This indicates that the auto-lock function doesn't appear to be correctly "finishing" its lock process, despite the actual door still locking. But as I previously mentioned, I have re-calibrated the lock both manually and automatically, and have experienced the same result since the fault started occurring - on both locks.
The lock of the door is a simple turn bolt - no real mechanism in it (doesn't click into place or anything - it just slides with the turning of the barrel).
With the first lock, I contacted Aqara, who made me go through a lot of troubleshooting steps and send logs, as they said they hadn't yet come across the issue, before concluding I needed to go back to the seller to get a replacement.
However, as this is the second lock that has exhibited the issue, I just wanted to see whether anyone else had a similar issue with the U200?
