Door lock won't open by hand

@captain11​ I would just a couple more item to that list:

• Make sure that your Smart Lock is updated to the latest firmware, which you can check from the Overview screen of the SimpliSafe app. If you see a Firmware Update box, tap it to get started (you'll need to be at the location, with your phone close to the Smart Lock, to to this)
• Try Re-Calibrating the lock through the Keypad Menu > Devices > [Your Smart Lock]. This will tell the unit to re-learn the correct locked/unlocked positions for your door.

@cassieebbrooks​ Sounds like a sync issue.  I would remove the lock from the system and then reinstall it to the system. Synching is part of the installation process and I know another customer that this step took care of the same issue for them.

@sanderbuitelaar​ have you already tried re-calibrating your lock? You can do so from the Keypad, under Menu > Devices > [Your Smart Lock].

@amie2814​ If you cannot manually unlock your Smart Lock after it auto-locks, it may be due to the strike plate on your door. I would try adjusting the strike plate to ensure that the deadbolt passes through it without hitting the side.

I'm having the same issue. I've had Simplisafe replace the lock 4 times, and it happens every time. Before writing this, I just installed the 4th lock they sent me. And once again, when it unlocks itself, it jams up and I have to really force it hard to turn the lock. It's not the striker or the door. The same thing happens when the lock isn't even attached to the door. This is so frustrating. Simplisafe tech supports claims to have never heard of this condition. Yet, I can find numerous postings online describing the problem and they all reported it to Simplisafe. 

Update: I figured it out and solved the problem. I realized this only happens on one of my four doors that have Simplisafe locks installed. Three doors that work flawlessly open from the right. The one that keeps jamming or freezing up opens from the left. I tried switching locks around and the problem persisted. I didn't think the issue was with the door, so I took the lock off the door and placed it on the table. I recalibrate the lock for a right opening door and the problem went away. It no longer jammed up. I then recalibrated it again while still on the table for a left opening door. And magically the lock didn't jam or freeze. I reattached the lock to the door and the problem is gone. It now works as it should.
