Why local Walnut experience matters
Local knowledge matters more in this trade than people realize.
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
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 Walnut lockouts in residential, commercial, and automotive locks are opened cleanly with no damage at all.
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.
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.
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.
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."
What to expect when you call us in Walnut
Our process is the same on every call in Walnut, whether it's a $99 lockout or a $5,000 access control build-out.
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. Cabinet & Drawer Lock Installation-specific testing. Walk you through any electronic options.
Honest pricing for Walnut customers
Transparency is more useful than a fake "starting at" number.
Standard cabinet & drawer 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.
Our pricing is in line with other reputable, licensed locksmiths in San Gabriel 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.
