Key Fob Programming in San Marino, CA.

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

Around The Huntington Library, we're often there for routine maintenance: smart-lock battery replacement, sticky deadbolts, and lost mailbox keys.

Cross-border jobs into Pasadena, South Pasadena, San Gabriel are routine, so the same fast response applies if your address technically straddles a city line.

Older San Marino 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 San Marino. 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 San Gabriel Valley 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 San Marino, 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.

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.

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 San Marino lockouts in residential, commercial, and automotive locks are opened cleanly with no damage at all.

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 San Marino 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. Key Fob Programming-specific testing. Document key count for vehicle records.

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

Standard key fob programming calls in San Marino 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.

What we won't do: quote a $19 "service call" on the phone, show up with a $400 number, and pressure you. That's the playbook of pop-up "lowest price" listings, not a real local locksmith.

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.
