Hello! The key stamp is in your second picture. It appears to ready "6#27." Can you confirm? If so, I would recommend our 24-637.

Actually the numbers are 6#23 (sorry the picture is poor) is the replacement still 24-673?

Great! Thanks for confirming. That actually ends up being the same balance, our 24-637. This can replace balances stamped with 623, 627, 631, or 637.
