Need a new lock because I can't get keys made

Question

I think I just need to lock, not the handle - the screws that attach the handle are 4" apart.
Please let me know what part would work or if you need more info.
Thanks!

Thanks for choosing SWISCO.com. I believe you should be able to replace the key cylinder in your handle with the 82-310. Take a look at the part and related videos I've posted and see if it will work for you.
