What This Site Is and Why It Exists

Foster City Locksmiths is an independent editorial guide, not a locksmith company, a referral service, or an affiliate network. We do not accept advertising, do not recommend specific companies, and do not receive commissions or referral fees.

The site exists because Foster City residents deserve accurate, unbiased information when hiring a locksmith. The locksmith industry in San Mateo County, like much of California, has a significant problem with scam companies advertising artificially low prices and then billing two to five times more after arriving on-site. Our research aims to arm you with the knowledge to recognize and avoid those situations.

Cost data is researched using publicly available pricing from licensed BSIS locksmiths operating in San Mateo County, verified against industry benchmarks, and updated at least twice per year. BSIS licensing information is sourced directly from the California state government at bsis.ca.gov.

We have no financial relationship with any locksmith company. This independence is what makes the cost and licensing data on this site trustworthy.

Editorial Methodology

Primary Sources First

Cost data, licensing requirements, and legal obligations are verified against California government sources, not secondary websites. BSIS licensing law comes from the California Business and Professions Code, cross-referenced with bsis.ca.gov guidance.

Regular Data Updates

Cost ranges are reviewed and updated twice yearly. San Mateo County pricing changes with economic conditions, and we flag outdated data rather than leaving inaccurate ranges in place. Each page displays the last-updated date.

Independence Maintained

We do not accept advertising or referral fees from locksmith companies. This means our assessments of typical costs, red flags, and scam patterns are not influenced by commercial relationships with the companies being described.
