This question already has an answer here:
I need to remove a Schlage double-cylinder deadbolt from our front door. Problem is, there is no visible way to remove it. There is a hole on one side and a pin with no head on the right. This deadbolt does not have caps covering screws not same as another user's post
I've tried this and that, but nothing worked. I've enclosed a picture of lock (hole on left and pin on right)
The only person who might have know anything is no longer with us, any ideas with how to remove deadbolt without destroying door would be appreciated.
