front door lock beside side light windows?
When we bought our mid '70s house, there was a lock on the front door that requires the use of a key to open it from either side. I assume this was installed because there are side light windows on both sides of the door and a thief could break the (tempered) glass and turn a regular deadbolt for easy entry. I want to replace the lock because I am more concerned about easy exit for our family if there was a fire than I am about burglars. My husband is not convinced that this is the way to go. I suggested that we consider a regular deadbolt and some secondary security (chain or something else), but a chain would not be in place if no one was home and we left through the front door.
Does anyone have a suggestion for a lock to be used on a front (exterior) door with side light windows? I am not ready to invest in replacing the entire door and surround.
