On Thurday night, I intentionally went through the parking lot of a locked out false alert at a local pharmacy, that had their door openers turned off, since it was past closing time. The next morning, I went past this location and the false alert was still locked out.
I did this again Friday night, only this time I went past this location at least 4-5 times, while out looking for some 35.5Ka. I again went past the location Saturday morning, and again, the false alert is still locked out.
I'm not sure what it takes to automatically unlock a locked out false alert that is no longer present, but it's definitely not one pass without the false alert present, that's for sure.
