Why local Walnut experience matters
Working as a locksmith in Walnut for 15+ years has taught us a few things about this part of San Gabriel Valley.
Quick access to CA-60 and CA-57 means our nearest van can usually clear the freeway and reach you fast — even at peak traffic times.
We dispatch across every Walnut ZIP — 91788, 91789 — and our techs know the residential street grid as well as the commercial corridors.
Cross-border jobs into Diamond Bar, Industry, West Covina are routine, so the same fast response applies if your address technically straddles a city line.
Many Walnut customers manage rental units, ADUs, or multi-generational housing — master key systems, smart locks, and audit-friendly hardware all become very useful.
Why Walnut customers choose One & Only Locksmith
Same crew, start to finish. Whether it's a 5-minute lockout or a multi-day master key system in Walnut, 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.
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.
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 Walnut traffic, knows our nearest van, and gives you a real ETA.
Local knowledge of Walnut. 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.
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.
What to expect when you call us in Walnut
Here's exactly what happens when you call us for service in Walnut.
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 Walnut 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. Smart Lock Installation-specific testing. Walk you through the app and best practices.
Honest pricing for Walnut customers
Pricing comes up on every call, so let's address it directly.
Standard smart lock installation calls in Walnut 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.
