The Simplex LL1021S26D41 is typically prepped for a Schlage Large Format Interchangeable Core (LFIC), and the core is usually not included. That means you would need a compatible Schlage LFIC core to use the key override feature on this lever set.
It is still a good idea to confirm the exact handing and model suffix before ordering, since Simplex L1000 series locks are offered in different core preps.
