High C core cylinders are designed to provide both exterior and interior doors with added security. These locks come with a curved lip stainless steel strike plate that serves to prevent unauthorized entry. In the event of change of access codes or keys, the lock can be easily re-keyed or replaced without requiring replacement of its main housing unit.
The lock also comes with two separate keys, which look identical but are cut differently. The control key allows future changes in the lock code, while the entry key is used for routinely opening and closing gates or doors. Although these locks tend to be more expensive than conventional ones, they offer greater security as it is very difficult to break them open using force.
High C core cylinder locks are widely used in residential as well as commercial buildings due to their effective security features.
