Install keyed handle

Thanks for posting. I'm afraid I'm not certain if I understand, as SWISCO does not supply sliding doors. Are you possibly talking about our 82-069 Handle Set? If so, you can adapt a keyed lock to this handle set with our 82-310. There should be a punch-out hole on the outside pull that you can knock out to insert the 82-310. If you are not talking about this handle set, or something else entirely, show us pictures of what you need and we'll see what we can do.
