Quick question. Does your door have a window in it?
If it does then I would recommend not getting a single sided dead bolt. A window would allow an intruder/thief to punch out the glass and reach in and unlock the dead bolt. If your other locks are Schlage this one can be rekeyed easily enough to match what you have.
If your door does not have a window in it this can be either swapped out for a new single sided dead bolt or, check with your local locksmith, they may have parts and pieces to turn what you have into a single sided dead bolt.
Our shop keep a lot of odd and ends either form swap out jobs or cannibalizing other locks for parts.
