What Is Lock Rekeying & When Do You Need It?
Rekeying is the process of changing the internal pin configuration of your existing lock so that a new key operates it — while the old key no longer works. It\’s one of the most cost-effective security upgrades available to South San Francisco homeowners and business owners. Salt air along the California coast accelerates corrosion in lock cylinders, making regular maintenance essential, making periodic lock maintenance and rekeying even more important for keeping your property secure.
