Why local Fremont experience matters
Working as a locksmith in Fremont for 15+ years has taught us a few things about this part of East Bay.
Around Tesla Fremont Factory and Mission Peak Regional Preserve, we're often there for routine maintenance: smart-lock battery replacement, sticky deadbolts, and lost mailbox keys.
Quick access to I-880 and I-680 and CA-84 and CA-238 means our nearest van can usually clear the freeway and reach you fast — even at peak traffic times.
We dispatch across every Fremont ZIP — 94536, 94537, 94538, 94539, 94555 — and our techs know the residential street grid as well as the commercial corridors.
Cross-border jobs into Newark, Union City, Milpitas are routine, so the same fast response applies if your address technically straddles a city line.
Newer construction in Fremont typically uses Grade 2 builder-grade hardware that we frequently upgrade to Grade 1 on request.
Why Fremont customers choose One & Only Locksmith
Live human dispatcher, 24/7. Call (888) 492-0666 and a real person picks up. No phone trees, no offshore call centers, no callback queues. The dispatcher knows Fremont traffic, knows our nearest van, and gives you a real ETA.
Bonded and insured. Bonded & Insured. We can provide our certificate of insurance, W-9, and license info on request — useful for HOAs, property managers, insurance claims, and commercial procurement.
Transparent pricing. You get a quote on the phone and a written quote on site before any work starts. We do not have a "minimum service charge" hidden in fine print, and we do not run the bait-and-switch game some pop-up locksmiths play.
Mobile, fully-stocked vans. We don't hand you a quote and then "go get the parts." Our trucks carry deadbolts, strikes, smart locks, panic bars, transponder blanks, programmers, extractors, and more — first-visit completion on the vast majority of jobs.
Real reviews, real reputation. Over 1,286 verified reviews and a 4.9-star average. We've built our business one neighbor at a time and we don't gamble that on a single bad job.
Same crew, start to finish. Whether it's a 5-minute lockout or a multi-day master key system in Fremont, the same technician owns your job from arrival to handoff. No "we'll send another guy out for that part."
What to expect when you call us in Fremont
Here's exactly what happens when you call us for service in Fremont.
1. You call (888) 492-0666. A live dispatcher picks up. They confirm the address, the issue, and any specifics ("front door deadbolt, Schlage, brushed nickel"). You'll get a clear ETA and a price range.
2. The nearest van rolls. We dispatch the closest fully-stocked technician to your Fremont location. You'll get a text or call when they're a few minutes out.
3. ID and authority verified. For lockouts and rekeys, we verify ownership or authority before opening anything. This protects you and us.
4. On-site assessment. Your tech inspects the lock, door, frame, hardware, and any related issues. We'll explain what we recommend and why.
5. Written, signed quote. Before any work begins, you get a clear written quote. If you don't want to proceed, you don't owe a dime.
6. Clean work. Hardware is installed straight, square, and to manufacturer spec. Strikes are reinforced into the king stud where appropriate. Old hardware is removed and disposed of.
7. Test and tour. We test the lock or system top to bottom, walk you through any new keys/codes/fobs, and answer questions.
8. Receipt and warranty. Itemized receipt by email, plus our workmanship warranty on every install.
9. Mailbox Locks-specific testing. Provide an extra duplicate on request.
Honest pricing for Fremont customers
Transparency is more useful than a fake "starting at" number.
Standard mailbox locks calls in Fremont are quoted by our dispatcher when you call. The number depends on a few real variables: the lock or system involved, time of day, distance from the nearest van, and any parts required. Once our technician is on site and has eyes on the job, you get a written quote — and you don't pay anything until you sign off.
Volume work — apartment turnovers, master keying, multi-door rekeys, and access control — is priced more aggressively per door because the setup is shared. Ask us for a multi-door quote.
Payment: Cash, Credit Card, Debit Card, Apple Pay, Google Pay. We email an itemized receipt the same day, useful for insurance claims, expense reports, or property management records.
