If only one person would be using this, this would be OK. If multiple users
could be using this at the same time, there's a nonnegligible chance your
code could generate multiple instances of the exact same 'unique' key.

There's only one reliable way to generate unique serial numbers: request
them from a single, central source that keeps track of the last such value
provided. No other approach is robust.
