Lock Rekeying in Mountain View, CA.

Working as a locksmith in Mountain View for 15+ years has taught us a few things about this part of Silicon Valley.

Around Googleplex and Castro Street, we're often there for routine maintenance: smart-lock battery replacement, sticky deadbolts, and lost mailbox keys.

Quick access to US-101 and CA-85 and CA-237 means our nearest van can usually clear the freeway and reach you fast — even at peak traffic times.

We dispatch across every Mountain View ZIP — 94035, 94039, 94040, 94041, 94042, 94043 — and our techs know the residential street grid as well as the commercial corridors.

Cross-border jobs into Sunnyvale, Los Altos, Palo Alto are routine, so the same fast response applies if your address technically straddles a city line.

Older Mountain View homes often have mortise or aging cylinder locks that need careful handling — drilling them is rarely the right answer the first time.

Local knowledge of Mountain View. 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 Silicon Valley and bring the right hardware on the first trip.

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 Mountain View traffic, knows our nearest van, and gives you a real ETA.

Same crew, start to finish. Whether it's a 5-minute lockout or a multi-day master key system in Mountain View, the same technician owns your job from arrival to handoff. No "we'll send another guy out for that part."

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.

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.

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.

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 Mountain View 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. Lock Rekeying-specific testing. Hand over fresh keys and recycle the old ones.

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

Standard lock rekeying calls in Mountain View 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 Silicon Valley. 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.

If any of these sound familiar, you're in the right place.

1. You just bought a new house.

2. A roommate or tenant moved out.

3. You lost a key or your bag was stolen.

4. An ex-partner has a copy you can't track down.

5. You want to consolidate three different keys into one.
