Our Story

More Than a Century
of Earned Trust

Grah Safe & Lock has been a fixture of San Diego security since 1914 — more than a century of protecting homes, businesses, and institutions across the region. What started as a family business remains one today: locally owned, deeply rooted in the community, and driven by a genuine commitment to keeping San Diego safe.

We are not a national franchise or a call-center locksmith. Our technicians are ALOA-certified, background-checked, and trained to handle everything from a residential rekey to U.S. Government Classified Container inspections. As an authorized Medeco Security Center, a SAVTA member, and an ASIS International affiliate, we hold ourselves to a professional standard that goes well beyond the industry baseline.

Whether you are a homeowner looking to upgrade your deadbolts, a property manager dealing with tenant turnover, or a business requiring enterprise-grade access control, Grah Safe & Lock provides the personalized, expert service your security deserves — no job is too large or too small.

Every Day

Both. You are welcome to visit our San Diego shop during business hours, or we can dispatch a certified technician directly to your location. We provide on-site estimates for all project types.

Unauthorized key duplication occurs when someone copies your key without permission — one of the most overlooked security vulnerabilities. High-security locks from Medeco, Schlage Primus, and Keymark use patented keyways that legally and mechanically prevent duplication without proper authorization, giving you documented control over who holds a copy.

Yes. Grah Safe & Lock is certified, licensed, and insured. All ALOA-certified members undergo in-depth background checks and hold full professional licensing — we can confirm our credentials before any work begins.

Yes. Grah is a certified GSA Container Inspector, authorized to work on U.S. Government Classified Containers. We serve clients ranging from single-family homeowners to high-security government properties.

Rekeying is the right move after employee or tenant turnover, lost keys, suspected unauthorized copies, or criminal activity in the area. It is faster and more economical than full lock replacement, and equally effective at denying access to previous keyholders.

We feature systems by Schlage, Medeco, and Salto, among others. Electronic access control provides user-level permissions, door-by-door scheduling, and a complete audit trail of who entered and when — capabilities a traditional keyed lock simply cannot offer.

We are open Monday, Tuesday, Thursday, and Friday from 7:30 AM to 4:30 PM, and Wednesday from 8:00 AM to 4:30 PM. Call (619) 234-4829 or submit a request online to schedule a service appointment or on-site estimate.

Absolutely. We serve homeowners, property managers, retail businesses, commercial office buildings, and high-security government facilities — with solutions customized to each client's specific security requirements.
