Lock Change for Bonita homes, done by licensed San Diego County technicians. A thirty-year-old lock that's been rained on, kicked, or rattled by a dozen tenants is not protecting you — it's just an obstacle for an opportunist. We replace worn-out, loose, or low-grade hardware with current ANSI Grade-1 or Grade-2 deadbolts and knobs sized for your door.
