For those of you who have a thicker outside storage door and need the longer 2-1/8" thumb locks and/or the key lock, contact Challenger for replacement locks. I searched the Internet without success. JR Products do not seem to have them. They also sell replacement doors. Hope this helps. I am posting the contact information by permission.
