A Piece of San Diego Security History You Can Trust

Grah Store front

Founded in 1914 by Ferdinand Grah and his son Rudolph Grah, Grah Safe & Lock has grown in concert with the city of San Diego. With over a century of experience serving the local community, our family business has thorough knowledge of the specific security needs of San Diego citizens and businesses.

Let us help you achieve security and meet regulations with our electronic locking devices, rekeying and master rekeying services, high security locks and keys, key duplications, safe sales and services, and video surveillance systems.

We are one of San Diego’s largest and most respected local locksmith companies. Your safety and security will always be our top priority.

Grah’s Professional Influence in History

In 1927 when Charles Lindbergh, the Legendary “Lone Eagle”, was building the Spirit of St. Louis, he turned to the finest craftsmen. One of them was Rudy Grah. For security, Lindbergh chose Grah Safe and Lock.

Rudy Grah installed the locks on the Spirit, helping create a piece of American history. Since 1914, Grah has evolved with the security industry. We now work with all forms of security from historical restorations to the latest in high technology. Grah continues to grow with the times!

Grah Will Give You Peace of Mind

Because quality and service count, Grah believes you have the right to be treated fairly no matter who you choose for your security needs.

Things to Consider When Choosing a Locksmith:

  • There are many uninsured “contractors” out there.
  • To protect yourself, ask to see their state issued license they are required to carry on their person.
  • Be sure to ask for proof of insurance by asking that a “certificate of insurance” be sent to you directly from their insurance company.

Grah Safe & Lock, Inc operates in a professional and business like-manner so you are protected. You get better results and we will be around to back up our work!

Tips for Saving Money

If you can, bring it into our shop.

When you bring it to us, you save on trip charges. Trip charges are the charges we charge to help cover the cost of fuel, drive time, auto wear and tear, and insurance. We are located at 939 University Ave. San Diego, CA 92103. We are off the I-163, on the corner of 10th and University.

Do you plan to give employees keys?

Employee theft accounts for over 30% of all business losses. If you plan to give your employees keys, switch to a high security keys that can not be copied without your permission. The initial expense is a small price to pay for the long term security protection, and it could save you thousands of dollars in theft and damage losses. You can also switch to an Access Control System. Access control systems have become much more user friendly and affordable. They no longer need to be hard wired to your building and anytime an employee leaves, their access privileges can be deactivated. Contact us for more information.
