Fast, Reliable Residential Locksmith Across San Bruno
If you’re locked out of a San Bruno house, need a deadbolt upgraded, or want old tenant keys rendered useless after a rental turnover near Tanforan, you want a residential locksmith who quotes the real price before leaving the shop. That’s how we work. A typical lockout in San Bruno runs $95 – $165, and a standard deadbolt replacement runs $185 – $310 including hardware and labor, with the full price confirmed in writing on the phone before anyone is dispatched. Call (409) 405-4485 and you’ll talk to a live person who can tell you exactly what the job will cost.
We know San Bruno’s streets, from the flatlands off San Mateo Avenue up to the tract homes above Sneath Lane. We know which doors have original mortise locks, which strikes are tired, and which cylinders have been rekeyed so many times the pins are worn smooth. That local familiarity means we show up with the right parts the first time, not a guess.
Why Preston Locksmith & Security Is San Bruno’s Preferred Residential Locksmith Company
Founded in 2008, Preston Locksmith & Security is part of the Relay Home Co. family, independently owned and operated, and led by Kevin Yoon. Our Residential Locksmith team works across the San Bruno area every week, so when you call for service in San Bruno, you’re not getting a dispatcher routing a stranger from two counties away. You’re getting a background-checked, uniformed technician who has already worked on doors like yours in your neighborhood.
Every San Bruno job is covered by The Relay Visibility Guarantee. That means a written price before work begins, a live trackable arrival time, before-and-after photos, and a written guarantee on every repair. If the repair fails within 365 days, we come back free under our 365-Day Done Right Promise, no charge and no argument. Nothing about our process leaves room for a bill that swells between the estimate and the invoice.
Our phones are answered by a live person 24/7. You will not sit through a voicemail tree when you’re locked out on a cold night in San Bruno. You’ll get a real human who can quote the job, schedule it, and send you a trackable arrival time right then.
Lost Key Replacement in San Bruno
Lost key replacement in San Bruno usually means one of two things: cutting a new key from a code or existing copy, or rekeying the lock so the lost keys no longer turn the cylinder. If you lost a single house key and don’t know who might have it, rekeying is the safer play. A standard rekey in San Bruno runs $65 – $95 per cylinder, and cutting a new key from a Kwikset or Schlage code runs $8 – $18 per key, with the written price confirmed before we start.
Rekey After Lost Keys
Rekeying swaps the internal pins so old keys stop working. No new hardware needed. For a San Bruno homeowner who lost a key with a house tag on it, this closes the security gap in about 20 minutes per lock.
Key Fabrication From Code
When you have the original key code stamped on your Kwikset or Schlage cylinder, we cut a fresh key on the spot. The door hardware stays untouched, and you’ll have working keys in minutes rather than replacing the entire lock.
House Key Locksmith in San Bruno
A house key locksmith in San Bruno handles more than cutting blanks at a kiosk. We handle worn keys that no longer fit the cylinder, broken key extraction from a deadbolt, and situations where a new homeowner wants every prior key in San Bruno neutralized without replacing all the hardware. That last job is a rekey, and it’s the most cost-efficient way to take control of a house you just closed on near El Camino Real.
Duplicate and Worn Key Work
Keys wear down, and so do the pins inside. A key that works in the deadbolt but not the knob usually signals a cylinder on its way out. We can measure the wear, decode it, and either cut a fresh key from the lock itself or rekey the cylinder to new pins.
Broken Key Extraction
When a key snaps off inside a Schlage or Yale deadbolt in San Bruno, the temptation is to grab needlenose pliers. Don’t. That usually pushes the broken blade deeper. We use thin extraction picks to pull the piece without drilling the cylinder, then test for pin damage before cutting a replacement.
Trusted Brands We Service in San Bruno
We stock common parts for Kwikset, Schlage, and Yale hardware in our San Bruno service vehicles, and we’re factory-trained on Medeco, Baldwin, Mul-T-Lock, Sargent, and Abloy for high-security cylinders and commercial-grade residential applications. That matters because a 1940s bungalow off Huntington Avenue often carries a Baldwin mortise lock that generic parts won’t fit, while a newer tract home above Sneath Lane might have a smart lock from Yale. We don’t sell you a universal replacement that dulls your door’s security. We match the hardware.
Common Residential Locksmith Problems We See in San Bruno Homes
- Frozen mortise locks on pre-war bungalows. The original 1920s – 40s mortise bodies near the El Camino corridor were built for brass internals, and decades of fog-driven moisture make the deadbolt throw stiff until the case is opened, cleaned, and lubricated or swapped.
- Worn strikes and milled-edge door sag. San Bruno’s older flatland homes settle. A door that sags a quarter inch means the deadbolt no longer lines up with the strike, and shimming the hinges plus replacing the strike is a better fix than forcing the lock.
- Builder-grade deadbolts on slope-side tract homes. The homes above Sneath Lane and around Crestmoor often shipped with cheap pin-and-tumbler deadbolts that bump open in seconds. Swapping those for an ANSI Grade 1 deadbolt with a hardened steel bolt is one of the most common upgrades we do.
- Rental turnover rekeys near Tanforan. Landlords converting units between tenants near Tanforan need old keys dead fast. Rekeying each cylinder runs $65 – $95, and we can do the whole unit in under an hour so the next tenant gets fresh key control.

FAQs About Residential Locksmith in San Bruno
A residential lockout in San Bruno costs $95 – $165, and no, the price will not change when the tech arrives. We give you the full price on the phone before dispatch, and that number is the number on your invoice. No call-out surcharge, no lockout fee added on the porch. Call (409) 405-4485 for an exact quote, and we’ll lock it in writing.
We can rekey most original mortise locks in San Bruno. The cylinder comes out, pins get swapped, and old keys stop working. If the mortise body itself is frozen or the tailpiece is broken, we’ll tell you and quote a replacement on the spot, but we never sell a full hardware swap when a rekey solves the problem. That’s a rental-friendly fix, and it costs the same $65 – $95 per cylinder.
Cutting a new key from code takes about 10 minutes once we’re at the door. Rekeying a cylinder so lost keys stop working takes about 20 minutes per lock. Most San Bruno jobs are done within an hour of arrival, and our tech’s live arrival time means you’re not waiting in a four-hour window.
Because we send you a live trackable arrival time and the tech’s name and photo before they knock. Our technicians are background-checked and arrive in uniform with Preston Locksmith & Security identification. And before any work starts, you get the written price. If the person at your door can’t produce those, it’s not us.
For a rental near Tanforan or anywhere in San Bruno with tenant turnover, bump-resistant matters. A standard ANSI Grade 1 deadbolt is strong against forced entry, but a bump-resistant cylinder with security pins, like the Kwikset SmartKey or Schlage B60N, blocks the most common key-bumping attack. The upgrade is usually $25 – $50 more than a basic Grade 1, and it’s worth it if previous tenants kept copies of their keys. Call (409) 405-4485 for a price based on your specific door.
