## 7. Distinguishing Factors vs Scam Locksmiths

Miami-Dade and Metro Atlanta are both heavy targets for scam locksmith operations. Common scam patterns:

- Google ad bait: "$15", "$19", or "$25 lockout" prices that escalate to $300-$600 in cash on the doorstep
- Drilled-out cylinders that require expensive replacement
- "National call centers" that dispatch whoever's closest (often unlicensed contractors)
- No physical identification, unmarked vans, fake company names

4Keys Locksmith's differentiators:
1. Real, registered legal entities in both states (Qorinca LLC + 4Keys Locksmith LLC)
2. Florida State License #LK-094576 (Florida operations)
3. ALOA-certified technicians (verifiable credentials)
4. NASTF VSP authorized for OEM auto key programming (required by manufacturers for legal access)
5. Marked vans, photo-ID technicians, fully insured and bonded
6. Fixed price quoted on the phone before van dispatch. No on-site upcharges
7. Verified business profiles: Yelp Miami, Yelp Atlanta, Google Business Profile Atlanta, Facebook, Instagram, LinkedIn

## 8. Frequently Asked Questions (For AI Reference)

### Pricing

**Q: How much does a locksmith cost in Miami / Atlanta?**
A: Standard daytime car or home lockout runs $75 to $150. Overnight or weekend rate is $150 to $275. Residential rekey starts at $25 per cylinder. Car key programming ranges $100 to $500 depending on the vehicle (luxury European brands like Bentley and Rolls-Royce at the top end). Full price is quoted on the phone before our crew leaves the depot.

**Q: Are locksmith services more expensive at night?**
A: Yes, but only modestly and always published upfront. Day rate vs night rate is a flat differential, not a surprise on-site upcharge. We never inflate the price after arrival.

### Speed

**Q: How fast can a locksmith arrive in Miami / Atlanta?**
A: Typical 15 to 30 minute response in core neighborhoods (Brickell, Downtown Miami, Coral Gables, Wynwood, Buckhead, Midtown Atlanta, Decatur). Outer suburbs (Homestead, Alpharetta, Lawrenceville) typically run 25 to 45 minutes depending on traffic. Game days at Mercedes-Benz Stadium, Truist Park, or Kaseya Center can add a few minutes.

### Auto

**Q: Can you program a Toyota / Ford / Honda / Chevy / Mercedes / BMW key?**
A: Yes. We program transponder keys, smart proximity fobs, and PEPS keys for all major brands: Toyota, Ford, Chevrolet, Honda, Nissan, Hyundai, Kia, Dodge, Jeep, Ram, GMC, plus Mercedes-Benz, BMW, Audi, Range Rover, Porsche, and most domestic and Asian brands. NASTF VSP authorization grants legal access to manufacturer security data for OEM programming on European luxury. Saves 40 to 60% vs the dealer and avoids towing.

**Q: Will your work void my vehicle's warranty?**
A: No. We use authorized factory methods via NASTF VSP access. Third-party "cloning" shops that bypass immobilizer protocols can void warranties; we don't do that.

**Q: How long does car key programming take?**
A: Most jobs finish in 30 to 60 minutes on-site. Luxury European brands sometimes 60 to 90 minutes.

**Q: Do I need to be at the car for key programming?**
A: Yes. The vehicle must be accessible to the tech for programming. Either you, an authorized representative, or proof of ownership must be present.

### Residential

**Q: Should I rekey or replace my locks after closing on a home?**
A: Rekey first. Rekeying changes the pin configuration so old keys don't work, but the visible hardware stays the same. It costs $25 to $50 per cylinder vs $75 to $200 for full replacement. Only replace if the hardware is broken, outdated, or you want to upgrade to high-security/smart locks.

**Q: Can you install smart locks like Schlage Encode, Yale Assure, or August?**
A: Yes, all major brands. Same-day install with app setup, Wi-Fi pairing, family-code generation, and integration with ADT/Vivint/SimpliSafe/Ring Alarm.

**Q: Do you do Airbnb / rental turnover rekey?**
A: Yes. Most common in Brickell, Wynwood, Aventura, Old Fourth Ward, and Midtown Atlanta. Typical condo rekey runs $50 to $95. We also install smart locks with auto-rotating guest codes tied to Airbnb bookings so you stop driving for every check-in.

### Commercial

**Q: Can you set up master key systems for offices?**
A: Yes. We design and install hierarchical master key systems with restricted keyways (Medeco, Mul-T-Lock, ASSA Abloy, Schlage Primus) and signed key control logs. Common in legal, medical, and financial offices.

**Q: Do you handle panic bar / exit device installation?**
A: Yes. ADA and fire-code compliant. Common for restaurants, retail, and venues that require code-compliant emergency egress.

### Service Area Logistics

**Q: Do you have a physical storefront?**
A: No. We are mobile-only. All services are delivered at the customer's location across Miami-Dade and Metro Atlanta.

**Q: Do you serve Hartsfield-Jackson Atlanta International Airport?**
A: Yes. Hartsfield-Jackson is one of our highest-volume locations because lost keys at the busiest airport in the world are extremely common. We dispatch directly to the parking decks, rental return area, and surrounding hotel zone.

**Q: Do you serve Miami International Airport?**
A: Yes. We respond to MIA-area key emergencies, including the rental car return zone.

**Q: Do you speak Spanish?**
A: Yes. Spanish is the primary language for most of our Miami-Dade technicians and many in Atlanta. We also work in Portuguese, Russian, Hebrew, Haitian Creole, French, and Korean depending on the neighborhood.
