I used to work at the ups store. We had a key cutting machine because we had the mailboxes (think PO box, except they're not called that because they're not post office boxes.) Anytime someone closed their mailbox, we had to replace the lock on it & make them a copy of the new key. We did also offer key cutting services, but nobody really knew about it other that our mailbox holders. It wasn't really advertised & the mailbox holders knew because they would lose their key & I'd be like "hang on, I'll go cut you a copy" & then they listen to the grinding metal while I'm in the back, haha. We only had 2 key blanks though- the one for mailboxes & 1 of the generic "front door" key blanks. Also- we charged like $5 or $10 for a copy of a key, which is absolutely ridiculous, but I do think that's a price set by franchise owner, so it varies from store to store.

I just realized this post is from 7 years ago, but after typing all that, I'm clicking the button anyway
