Keyed Cylinder

Thanks for writing in! I believe you may be able to convert the handle to a keyed one, using the 82-310 Key Lock. For instructions on how to install it in the handle, take a look at the video tutorial below.

If you would prefer to purchase the entire handle set, take a look at the 82-030A Centered Keyed Handle Set.

Both come with a set of compatible keys. Each of their dimensions can be found on the website.
