Door replacement

Hello,

The dimensions of the door lock is 5/16 and 1/2in and the inside holes for deadbolt locking is 29/32. The inner part is one single piece and the outside part is 2 separate pieces.
Checking to see if this is a match. The door is a little under 2 inches thick. The lock handle is on the handle and key hole is on the top. Also, the inner part is fine and works we just need to replace the outer due to not having a working key. Is it possible only to replace the outside part?
