High-Security Locks in Fremont, CA.

Fremont has its own personality, and our service approach reflects it.

Around Tesla Fremont Factory and Mission Peak Regional Preserve, we run a lot of commercial calls — restaurants, retail, and offices that turn over staff frequently.

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.

Many Fremont customers manage rental units, ADUs, or multi-generational housing — master key systems, smart locks, and audit-friendly hardware all become very useful.

Local knowledge of Fremont. Older homes have older mortise locks. Newer high-rises have proprietary cylinders. Cluster mailboxes have specific USPS standards. We know what's typical for the East Bay and bring the right hardware on the first trip.

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.

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.

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.

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."

Transparency is the whole point — here's what your call to One & Only Locksmith looks like end to end.

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. High-Security Locks-specific testing. Document the system for future service.

Pricing comes up on every call, so let's address it directly.

Standard high-security 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.

Our pricing is in line with other reputable, licensed locksmiths in East Bay. If a quote sounds dramatically lower than ours, it's almost always going to climb dramatically once a technician is on site.

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.

Most high-security locks calls in Fremont happen for one of a small number of reasons.

3. You've had a previous break-in attempt.

4. You store valuables, firearms, or business inventory at home.

5. You want a single restricted key system across the property.
