Latch is not workin

Thanks for reaching out to us. Your old handle set was discontinued and is no longer available, unfortunately. However, take a look at the 82-005 surface mount handle assembly. This measures 4-15/16" on the installation hole centers so you'll need to drill new holes. There is also an included keeper so you'll also need to make sure there's room on the jamb to install it. Take a look at the specifications along with the related videos and see what you think.
