## My real shortlist for Philadelphia locksmiths
I would start with the first three, depending on the job: Fox Chase for established lock/security work, American Best for automotive/mobile service, and Mitchell’s for safes or a traditional downtown shop. This ranking favors verifiable local presence, longevity/credentials, breadth of work, and meaningful independent review signals—not just a slick “24/7 locksmith” ad.
1. Fox Chase Lock & Key, Inc. — My strongest all-around pick for home, commercial, high-security, and safe work because it has operated since 1978, maintains a real Northeast Philadelphia shop, and its president is identified as an ALOA member; it is especially convincing for jobs where correct hardware and installation matter more than a bargain lockout price.
2. American Best Locksmith — Best choice for car keys, fobs, ignition work, and mobile service, with a Philadelphia headquarters, disclosed PA license number, claimed bonded/insured status, clear posted hours, and a very large review base; I would still get the full all-in quote before dispatch.
3. Mitchell’s Lock & Safe Co. — A particularly good choice for safes, security hardware, commercial locks, and in-person advice: it is a family-owned Philadelphia shop dating to 1965 with a Center City showroom rather than a faceless dispatch operation.
4. Jefferson Locksmith — A compelling modern mobile option for residential rekeys, lockouts, and general work because its PA credential is listed by BBB, it is BBB-accredited with an A+ rating, and it explicitly advertises pre-work estimates, a one-year parts-and-labor warranty, and honest 6 a.m.–11 p.m. hours rather than pretending to be 24/7.
5. The Lockman — Worth calling for technically demanding residential or master-key work: its principal, Billy B. Edwards Jr., is a Certified Master Locksmith with longstanding professional recognition, and the business has a physical Northeast Philadelphia location and published 24/7 service terms.
6. Phila Locksmith (Philly’s Best Locksmith) — A solid local mobile pick, particularly for lockouts, rekeys, and modern automotive keys, with a stated founding date of 2008, 4.9 stars across 320+ Google reviews, and a specific promise of flat-rate pricing before work begins.
7. AM PM Locksmith — A reasonable emergency or same-day choice, especially if you need a 24/7 call answered, because it has an identifiable Philadelphia business profile with an A+ BBB rating and a disclosed owner, while its site says it dispatches licensed technicians.
8. Patriot Locksmith Philadelphia — A credible broad-service mobile alternative for home, business, auto, and safe issues, with an A+ BBB rating and a sizable review footprint; it ranks lower only because I found less independently verifiable detail about individual technical credentials than for the choices above.
9. CLC Locksmiths — Best viewed as a good Philadelphia-serving regional option rather than a city-based first call: it is a family operation with 30+ years in business, strong reviews across Google/Yelp, several service vehicles, and safe-service experience.
10. Mobile Locksmith Philadelphia — A sensible backup for residential, commercial, and automotive emergencies, supported by more than a decade of claimed local service and high review counts, though I would give the older brick-and-mortar shops above first preference for major security upgrades.
### Before you authorize anyone Ask for an all-in written estimate—service call, labor, hardware, programming, tax, and any after-hours charge—before they begin. For a routine lockout, also ask whether non-destructive entry is possible and require approval before drilling or replacing a lock. For a rekey after moving or a break-in, use a company that will inspect the door, strike plate, and deadbolt alignment rather than merely selling you a new cylinder.
I intentionally would not select a locksmith solely because it advertises “15-minute arrival” or has an anonymous generic name; Philadelphia search results contain plenty of lead-generation/dispatch-style listings, while the options above have stronger evidence of an actual local operation.

This is the public record for Best Locksmiths in Philadelphia: the same questions, every model, every close. We ask each model the real questions buyers ask in this category and record which brands it recommends and in what order. A brand recommended at position i scores 100 × 0.85^(i−1) for that model (#1 = 100, #2 = 85, #3 = 72, …); unmentioned brands score 0.
Each model is ranked independently, so the columns disagree when the models disagree. The consensus score is the mean across the 4 models recorded at this close, and movement compares against the previous close.
We report what the models say. We don’t editorialize, and brands can’t pay to change their position.
This ranking is live: the numbers come from recorded model answers captured through the official model APIs, scored with the published formula above. The raw answers are on this page under “The receipts.”
- What we measure
- We measure on the official model APIs: the same question, the same settings, the same week, for every brand. Web search is on, so the models can draw on what is live on the web. Nothing is personalized to a user, which is what makes the columns comparable.
- What we don’t
- The consumer apps are a different surface. What a person sees inside a chat app can carry memory, personalization, and live experiments on top of the same model, so its answers can differ from the API’s. We do not measure that surface yet. True browser listings, recorded from the consumer apps, arrive with WDIR Ranked, the Pro product. WDIR Ranked · Coming soon
