Questions and answers of the customers

  1. A

    Absolutely, we offer this model with the core included. You can order the L1021B which includes a Falcon IC core, the L1021S (Schlage core), L1021C (Corbin core), L1021M (Medeco core), or L1021R (Sargent core).  If you have an existing Schlage key system, you'll want to choose the Schlage model. If you don't have a key system in place, choose the L1021B with the falcon key core. We can also key your cores alike when ordering multiple locks.
