Hi, I have a schlage electric lock at my apartment. For the first time in nine months, this morning, I couldn’t get it to lock. After a couple of minutes, it finally made the noise that indicated it was locked. I spent another 5 minutes trying to open the door, turning the lock, etc and couldn’t get it opened, so I’m confident it is locked. What causes this issue and can the lock unlock itself randomly because of this issue while I am away? Any experience or knowledge you have is appreciated.
