A complete guide to the six main service categories offered by BSIS-licensed locksmiths serving Foster City and San Mateo County.
What locksmiths do in Foster City: BSIS-licensed locksmiths in San Mateo County offer six main service categories: residential, commercial, automotive, emergency lockout, rekeying, and smart lock installation. Each category has different cost drivers, equipment requirements, and licensing considerations.
California's BSIS licensing requirement means every legitimate locksmith working in Foster City has been background-checked and carries mandatory insurance. This guide breaks down each service category so you know what to ask for and what to expect to pay.
Service Type 1
Residential locksmith work covers everything related to home security hardware: locks, deadbolts, door knobs, sliding door locks, and garage entry points. In Foster City's mix of single-family homes, condos, and townhomes, this is the most common locksmith service category.
Typical cost in Foster City: $75-$175 for standard services. New deadbolt installation runs $100-$300 including hardware.
Service Type 2
Commercial locksmith work in Foster City covers offices, retail spaces, industrial buildings, and multi-tenant commercial properties. The equipment and complexity level is significantly higher than residential work, which is why commercial-grade BSIS licensees have additional training requirements.
Typical cost in Foster City: $250-$1,200+ depending on system complexity and number of doors.
Service Type 3
Automotive locksmith work covers car lockouts, transponder key cutting, key fob programming, and ignition repair. This is the most equipment-intensive locksmith category. A legitimate automotive locksmith in Foster City carries an OBD-II programmer, key cutting machine, and proprietary software for multiple vehicle brands.
Typical cost in Foster City: $75-$150 for lockout, $175-$450 for key cutting and programming. European luxury vehicles (BMW, Mercedes) typically cost more and may require dealer involvement.
Service Type 4
Emergency lockout service covers being locked out of your home, office, or vehicle during the locksmith's posted operating hours. "Emergency" in the locksmith industry refers to urgency of the situation, not a different service category. Costs may be slightly higher during evenings or weekends.
What to have ready: Your government-issued ID with a matching address (or vehicle registration for car lockouts). All licensed locksmiths in California must verify authorization before proceeding.
Service Type 5
Rekeying is the process of changing the internal pin configuration of an existing lock cylinder so that old keys no longer work. It is the most cost-effective way to change who has access to your home or office, and is the standard recommendation when moving into a new Foster City property.
Cost vs. replacement: Rekeying typically costs $25-$75 per lock. Full lock replacement runs $100-$300 per lock. Unless the hardware is damaged or you want an upgrade, rekeying is almost always the better option.
Service Type 6
Smart lock installation replaces your traditional deadbolt with a WiFi or Bluetooth-enabled device controlled via smartphone. BSIS-licensed locksmiths in Foster City handle the hardware installation, app configuration, and integration with existing home automation platforms like Google Home, Amazon Alexa, and Apple HomeKit.
Typical cost: $150-$350 installed, including the device and app configuration. Most installations take 45-90 minutes.
