I have an old metal security door that I am looking for a replacement lock or tumbler. I got locked out of my house because I lost the key to the security door. The locksmith came and opened the door, however, since I did not have a backup key the door is disabled. The door is old and the name on the lock panel is PADO. I looked up on your web site and it looks like your product code
40-049 would be usable. Can you verify that would work for me?
