I would like to replace this handle with one that has an exterior key lock. Hopefully you can read the model number on the door label. Do you have one that will work?

See our 82-030 Handle Set. You can adapt the 82-310 Key Lock to the outside pull; this blog article here explains how. If you need a new mortise lock as well, see the 82-218.
