Know the service you need (lockout, rekey, new install), your location, and any relevant details (vehicle make/model for automotive, door thickness for installs).
Call two or three licensed locksmiths before committing. Ask for a total estimate including any service or travel fees. Legitimate locksmiths quote before arriving.
Licensed locksmiths display their BSIS Locksmith License number on service vehicles and invoices. Any credentialed company will readily confirm their license status when asked.
Before any work begins, confirm the price matches the phone quote. If the on-site price is significantly higher with no legitimate explanation, you can decline and pay nothing.
A proper receipt includes the business name, BSIS license number, itemized services, parts used, and final price. Keep it for warranty claims or disputes.
What sets a reliable Foster City locksmith apart: BSIS-licensed operators provide a written quote before touching any lock, arrive in marked vehicles with company identification, and give you an itemized receipt showing exactly what you paid for. Stick with BSIS-licensed providers and confirm the all-in quote before work begins.
Foster City homeowners frequently ask whether smart locks are worth the upgrade. Here is an honest comparison based on security ratings, cost, and practical use.
Bottom line: A quality Grade 1 deadbolt professionally installed remains the best value for most Foster City homes. Smart locks add meaningful convenience features but require ongoing maintenance and a higher upfront investment.
These are illustrative experiences shared by Foster City and San Mateo County residents. Experiences vary by locksmith chosen.
"Used this guide to find a properly licensed locksmith. The tech arrived within 30 minutes, quoted me upfront, and rekeyed three locks for exactly what he said. Knowing what to look for made the whole experience stress-free."
"Locked my keys in the car near the lagoon. The cost table helped me know I should be paying around $100, not the $400 the first person quoted. Found a BSIS-licensed locksmith who charged $95 and got to me in 25 minutes."
"Just moved into a Foster City condo and was nervous about the previous owner's keys. The rekeying guide explained exactly what to ask for and how much to expect. Got three deadbolts rekeyed for $210 total, which matches exactly what the guide said."
"Managing a small office building in Foster City. The commercial section helped me understand master key systems and access control options. Very useful for someone who had no idea where to start."

Rekeying changes the internal pin configuration of the existing lock cylinder so old keys no longer work. It costs $60 to $100 and keeps your current hardware. Lock replacement installs an entirely new lock and costs $100 to $250 plus hardware. Rekeying is the better choice when the lock is in good working condition, such as when moving into a new home.
No. Licensed California locksmiths are required to verify proof of ownership before opening any vehicle. Have your driver's license and vehicle registration ready. This is a legal safeguard for you. Any locksmith willing to open a car without documentation is not following California law.
Premium smart locks from Schlage and Yale match Grade 1 deadbolts in physical security. The main risk with smart locks is digital: weak Wi-Fi passwords or outdated firmware create vulnerabilities traditional locks do not have. A Grade 1 traditional deadbolt professionally installed is still an excellent and simpler choice for most homes.

Most also cover Redwood Shores, Belmont, San Mateo, and San Carlos. Always confirm the service area and any travel fees when calling.
Call a BSIS-licensed locksmith. While waiting, verify there are no other unlocked entry points and stay safe. Do not attempt to force entry yourself as door and frame damage is expensive. Most Foster City lockouts during posted hours are resolved within 20 to 40 minutes. Confirm the price before any work begins and ask for a written receipt.
Programming a key fob or transponder usually costs $50-$150 in labor on top of the fob itself, which ranges from about $25 for a basic remote to $300+ for a proximity or smart key. A local auto locksmith is almost always cheaper than the dealership.
Most mobile locksmiths offer same-day service and can typically reach you in Foster City within 20-45 minutes for an emergency lockout, depending on traffic and time of day. Always confirm the ETA and the call-out fee on the phone before you book.
Tipping is not expected because the service fee already covers the work, but many customers tip $10-$20 for a fast late-night lockout or for going the extra mile. A five-star review is just as appreciated and helps a local locksmith even more.
