Spare Car Key & Key Duplication in Santa Monica, CA.

Working as a locksmith in Santa Monica for 15+ years has taught us a few things about this part of Westside.

Around Santa Monica Pier, we're often there for routine maintenance: smart-lock battery replacement, sticky deadbolts, and lost mailbox keys.

Quick access to I-10 and CA-1 means our nearest van can usually clear the freeway and reach you fast — even at peak traffic times.

We dispatch across every Santa Monica ZIP — 90401, 90402, 90403, 90404, 90405, 90406 — and our techs know the residential street grid as well as the commercial corridors.

Cross-border jobs into Venice, Pacific Palisades, Brentwood are routine, so the same fast response applies if your address technically straddles a city line.

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

Non-destructive entry first. Our locksmiths are trained to pick, bypass, and decode. We drill only as a last resort, and only after explaining why. Most Santa Monica lockouts in residential, commercial, and automotive locks are opened cleanly with no damage at all.

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.

Local knowledge of Santa Monica. 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 Westside and bring the right hardware on the first trip.

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

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 Santa Monica 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. Spare Car Key & Key Duplication-specific testing. Test all functions on both keys.

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

Standard spare car key & key duplication calls in Santa Monica 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 Westside. 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 only have one car key and that's risky.

2. Spouse or family member needs their own key.

3. Teen driver getting their own key.

4. Used car only came with one key.

5. Want a backup for vacation or rental scenarios.
