Why Westmont customers choose One & Only Locksmith
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.
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.
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 Westmont 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.
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 Westmont traffic, knows our nearest van, and gives you a real ETA.
What to expect when you call us in Westmont
Our process is the same on every call in Westmont, 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 Westmont 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. Transponder Key Programming-specific testing. Test starts and door operation.
Honest pricing for Westmont customers
Pricing comes up on every call, so let's address it directly.
Standard transponder key programming calls in Westmont 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.
