Why local Cerritos experience matters
Local knowledge matters more in this trade than people realize.
Around Cerritos Auto Square, we're often there for routine maintenance: smart-lock battery replacement, sticky deadbolts, and lost mailbox keys.
Quick access to I-605 and CA-91 means our nearest van can usually clear the freeway and reach you fast — even at peak traffic times.
Cross-border jobs into Artesia, Lakewood, Norwalk are routine, so the same fast response applies if your address technically straddles a city line.
Newer construction in Cerritos typically uses Grade 2 builder-grade hardware that we frequently upgrade to smart-and-mechanical hybrid on request.
Why Cerritos customers choose One & Only Locksmith
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.
Same crew, start to finish. Whether it's a 5-minute lockout or a multi-day master key system in Cerritos, 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 Cerritos traffic, knows our nearest van, and gives you a real ETA.
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 Cerritos
Our process is the same on every call in Cerritos, 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 Cerritos 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. After-Hours Service-specific testing. Receipt provided same day.
Honest pricing for Cerritos customers
Pricing comes up on every call, so let's address it directly.
Standard after-hours service calls in Cerritos 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 Gateway Cities. 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.
