California Law
California requires all locksmiths to hold a license from the Bureau of Security and Investigative Services (BSIS). This is not optional. Hiring an unlicensed locksmith in Foster City puts you at risk.
Decision Guide
Three things every San Mateo County resident should know before calling any locksmith.
BSIS-licensed locksmiths pass criminal background checks. This matters because they have unrestricted access to your home or vehicle during the job.
A licensed locksmith provides a written estimate before any work begins. If a technician refuses to quote upfront or inflates the price after arrival, that is a red flag.
Legitimate locksmiths require you to prove you are authorized to access the property or vehicle. This protects both you and the locksmith under California law.

Step-by-Step
Four steps every resident should follow before calling a locksmith. These prevent scams and ensure you get a licensed, insured professional.
Search "locksmith Foster City CA" rather than generic terms. This surfaces local BSIS-licensed operators rather than national aggregators who subcontract to unlicensed techs.
Before anyone arrives, ask for the locksmith's BSIS license number. Verify it in real-time at bsis.ca.gov. A legitimate locksmith will not hesitate to provide it.
Insist on a written or confirmed quote before any work begins. Scam locksmiths quote $35 over the phone and charge $300+ on arrival. A real quote protects you.
Have your ID and proof of residency ready (utility bill, lease, title for vehicles). A licensed locksmith is required by California law to verify your right to access the property.

Common Questions
Direct answers to the questions San Mateo County residents ask most often about locksmiths.
A residential locksmith in Foster City typically costs $75-$175 for standard services like rekeying or lockout assistance. Automotive key programming runs $175-$450 depending on the vehicle make and model. Commercial access control installation starts at $250 and can reach $1,200+ for multi-door systems.
Always request a written estimate before authorizing any work. California law does not cap locksmith rates, so pricing varies between providers.
Yes. California requires all locksmiths to hold a license from the Bureau of Security and Investigative Services (BSIS). You can verify any locksmith's license number in real-time at bsis.ca.gov. Always ask for the license number before they arrive.
Rekeying changes the internal pin configuration of your existing lock cylinder so old keys no longer work. It is significantly cheaper ($25-$75 per lock) than full replacement and is ideal when the lock hardware is in good condition.
Full lock replacement ($100-$300+ per lock) is appropriate when the lock is damaged, you want a security upgrade, or you are switching from traditional to smart lock hardware.
Step 1: Ask for the BSIS license number before they arrive. Step 2: Verify it at bsis.ca.gov. Step 3: Ask them to show a photo ID when they arrive. Step 4: Get a written estimate before any work begins.
Red flags: refusing to give a license number, quoting a very low price over the phone that changes dramatically on arrival, unmarked vehicle with no company identification.

Luxury European brands (BMW, Mercedes, Audi) and Teslas typically require dealership programming due to proprietary encrypted systems.
