About PDQ SD / GT Series
PDQ Manufacturing is a US-based commercial hardware manufacturer producing Grade 2 and Grade 1 cylindrical locks, mortise locks, exit devices, and door closers. The SD Series (Standard Duty) and GT Series are PDQ's most-specified Grade 2 commercial cylindrical lever lines — ANSI/BHMA A156.2 Series 4000 Grade 2 certified, UL Listed for 3-hour A-label fire doors, and competitively priced against Falcon W and Kwikset Commercial.
PDQ's advantage in the Grade 2 market is function range and keyway flexibility. The SD and GT Series cover the full commercial function set (passage, privacy, entrance, office, classroom, storeroom, corridor, apartment) in multiple lever designs and finishes, with standard compatibility for Schlage C, Kwikset KW1, and SFIC keyway options — making it easy to slot into existing buildings regardless of which primary brand is already installed. For public restroom doors, medical office interior doors, retail stockrooms, and light-commercial office applications where ANSI Grade 2 is adequate, PDQ is a common specifier's choice for stretching the hardware budget without sacrificing code compliance.
PDQ also produces MR Series mortise locks, SP Series panic hardware, and door closers — so a full commercial hardware package can be specified within the PDQ brand, simplifying ordering and warranty management. The trade-off versus Allegion/ASSA ABLOY/dormakaba brands is a smaller dealer network and thinner parts availability for older units — typical of value-tier brands. For new construction and retrofits where upfront cost matters and service life of 7-12 years is acceptable, PDQ is competitive. Key-En-Lock services the PDQ commercial lineup across Brevard County.

ANSI A156.2 F-Function Quick Reference
ANSI A156.2 standardizes cylindrical lock functions so specifications work across brands. When an architect specs "F82 entrance/office," any Grade 1 or Grade 2 cylindrical lock from any brand will meet that function — the choice is brand, keyway, and trim preference.
| ANSI | Function |
|---|---|
| F75 | Passage — no locking |
| F76 | Privacy — inside thumbturn |
| F81 | Entrance — key + push-button |
| F82 | Entry/Office — key locks outside |
| F84 | Classroom — key outside, inside free |

Call (321) 224-5625Frequently Asked Questions
Why would I spec PDQ instead of Falcon W or Kwikset Commercial?
Three reasons. First, price — PDQ is typically 10-20% cheaper than Falcon W at the equivalent function. Second, keyway flexibility — PDQ offers Schlage C AND Kwikset KW1 AND SFIC in the same product line, giving you more master-keying options than Falcon W (which is Schlage-only). Third, full product line — PDQ makes cylindrical, mortise, exit devices, and closers under one brand, simplifying ordering on multi-opening projects. Trade-offs: smaller dealer network, thinner parts availability for older units.
Is PDQ really Grade 2 certified?
Yes — ANSI/BHMA A156.2 Grade 2 on the SD and GT Series. Verify certification on the specific model when ordering. PDQ also makes Grade 1 cylindrical locks under their higher-tier product lines, but the SD and GT are the common Grade 2 commercial specs.
Where does PDQ commonly get specified?
Public restrooms, medical office interior doors (exam rooms, consult rooms, office doors), retail stockrooms and back-of-house, light-commercial office interior doors, community centers, and small municipal buildings. Anywhere Grade 2 is adequate and budget matters more than 20-year service life.
How long will PDQ commercial last in typical service?
Grade 2 cycle rating is 400,000 cycles — translates to 7-12 years in typical light-commercial service. For doors seeing 50-100 cycles per day (medical exam rooms, office interior, public restrooms), this is the right spec. For high-traffic doors (entries, high-volume retail), step up to Grade 1.
Can I rekey PDQ to match existing Schlage keys?
Yes. PDQ SD and GT Series ship with Schlage C keyway as standard, so direct rekey into an existing Schlage master system is straightforward. We handle on-site rekey for PDQ commercial installations.
Is PDQ fire-rated?
Yes — UL Listed for 3-hour A-label fire doors on the Commercial SD and GT lines. Verify the specific model and UL label during NFPA 80 annual inspection.
Does PDQ have an electrified option?
PDQ offers electrified variants on select Grade 2 and Grade 1 models for access control integration. For electrified cylindrical, many spec'ers step up to Schlage ND80PDEL, Best 9K0L, or Sargent 10XG05-EL given the higher reliability and deeper access control support. For budget electrified retrofit, contact us to verify which PDQ electrified models are appropriate for your access control platform.
