DFA Storm Door Key needed

Question

I am locking to purchase a lock for this door handle, which is on my DFA storm door. I had a locksmith look at my door, and he said it is unable to be rekeyed. I am hoping that 40-089 is the item I am looking for. Unfortunately, i was unable to take a pic of the internal workings of the current lock. It is oval, matching 40-089, but it has 2 flappers (I believe that's what they are called) - one for the thumbturn and one for the key. Will 40-089 work for Mr, or is rpthere another lock that I need? Thank you.

It's really hard to be sure, but take a look at our 40-123, and the 40-129 offset key cylinder. See if either of these match up to your key lock. I don't believe the 40-089 will fit you handle, to be honest. The shape is not the same. You may want to contact a professional to replace this lock.
