The U200 was purchased in November 2025, so six weeks later, the lubricant dried, and the lock was constantly jamming. I had already returned a lock for the same problem, but I bought it on Amazon, so it was quick. I bought another one on Aqara UK, with extra accessories. Replacing the lock bought on Aqara UK would probably take over a month, and the same thing would probably happen again in a few months. I don’t want to waste time replacing it.
The new locks will have the same problem if they use bad grease or replace the gear with bad grease.
I don’t understand how they can use such poor lubrication, be forced to replace and repair so many locks, and still sell new locks with the same problem.
@Sugar Thank you for sharing your experience with the U200 door lock and the detailed video—it’s really helpful for other users to be aware of such issues! It must be frustrating to encounter the same lubrication problem again after a replacement. Your feedback about the grease quality is valuable, and we appreciate you taking the time to highlight this.
