Yale / ACCENTRA 5400LN Commercial Locks
ASSA ABLOY ACCENTRA's Grade 1 commercial cylindrical lever lock — companion to the 8800 mortise lock. Reinforced 14-gauge steel chassis, field-reversible latch, non-handed strike, and Medeco M3/X4 high-security cylinder retrofit compatibility. Formerly Yale 5400LN, rebranded to ACCENTRA in 2024.
Parent company: ASSA ABLOY (ACCENTRA — rebranded from Yale Commercial 2024)
About Yale / ACCENTRA 5400LN
The ACCENTRA 5400LN Series (formerly Yale 5400LN, rebranded by ASSA ABLOY in 2024) is ACCENTRA's Grade 1 cylindrical lever lock — the companion cylindrical spec to the 8800 Series mortise for buildings where architects want consistent visual design and unified key control across cylindrical and mortise openings. Every 5400LN is ANSI/BHMA A156.2 Series 4000 Grade 1 certified and UL Listed for 3-hour A-label fire doors.
The chassis uses 14-gauge reinforced steel with a field-reversible latch and non-handed strike — same construction philosophy as the 8800 mortise, which means installation is fast and spec changes don't require re-ordering. A standard 5400LN drops into standard 2-1/8" cross-bore prep and can be handed/re-handed in the field without disassembly.
Where the 5400LN offers a distinct advantage over other Grade 1 cylindricals is Medeco cylinder retrofit compatibility. The 5400LN accepts Medeco M3 and Medeco X4 UL437 high-security cylinders as direct drop-in replacements — a common high-security upgrade path for existing installations. Keep the standard ACCENTRA 5400LN chassis, swap the cylinder for Medeco, and the opening becomes UL437-certified pick/drill/impression resistant at a fraction of the cost of a full proprietary high-security lock. Standard keyways run GA (factory default) through patented Para®. Also available with SFIC and ACCENTRA LFIC housings. Key-En-Lock is an ASSA ABLOY authorized dealer and handles both legacy Yale 5400LN and current ACCENTRA 5400LN as the same product line — parts interchange.

ANSI A156.2 F-Function Quick Reference

| F75 | Passage — no locking |
| F76 | Privacy — inside thumbturn |
| F82 | Entry/Office — key locks outside |
| F84 | Classroom — key outside, inside free |

What happened to Yale Commercial — is ACCENTRA 5400LN the same?
Yes. In 2024, ASSA ABLOY rebranded its Yale Commercial business to ACCENTRA. The 5400LN cylindrical series (like the 8800 mortise series) is identical post-rebrand — same product, same part numbers, same compatibility. Parts interchange between legacy Yale 5400LN and current ACCENTRA 5400LN. Packaging and branding changed; the hardware did not. Existing Yale 5400LN installations accept new ACCENTRA parts without modification. The rebrand does not affect the residential Yale brand (Yale Locks and Hardware) which remains unchanged.
Why would I spec 5400LN over Schlage ND or Best 9K?
Three primary reasons. First, 8800 mortise pairing — if your building spec includes ACCENTRA 8800 mortise locks on entry doors, the 5400LN cylindrical shares trim design and GA keyway so the building has visual and operational consistency. Second, Medeco cylinder retrofit path — the 5400LN accepts Medeco M3/X4 UL437 high-security cylinders as direct drop-ins, giving you a lower-cost upgrade path to UL437-certified security versus buying a dedicated high-security lock. Third, fast install — field-reversible latch, non-handed strike, and free-floating front plate reduce installation time per opening.
How does 5400LN accept Medeco cylinders?
The 5400LN uses a standard 6-pin KIK (key-in-knob) cylinder format that's dimensionally compatible with Medeco M3 and Medeco X4 high-security cylinders. Order the 5400LN "less cylinder" (suffix LC), then install a Medeco M3 or X4 cylinder during setup. No drilling, no lockbody modification. Result: 5400LN chassis with UL437-certified pick/drill/impression-resistant cylinder. Cost is roughly $80-$130 for the Medeco cylinder added to the $150-$250 5400LN chassis — far less than a dedicated high-security cylindrical lock ($400-$700+). Rekey to existing Medeco-keyed buildings is straightforward when using the same Medeco keyway across the portfolio.
Is 5417LN code-compliant for Florida K-12 classroom security?
Yes. The 5417LN (F110 classroom security) meets current Florida school hardware requirements. Key in either lever locks/unlocks the outside — teacher locks from inside without opening the door during lockdown. Inside lever always free under NFPA 101. UL 3-hour fire rating when installed on fire-rated classroom doors.
Can I replace an existing Yale 5400LN with an ACCENTRA 5400LN?
Yes — direct swap. Chassis dimensions, strike dimensions, cylinder thread, and trim mounting holes are identical. An ACCENTRA 5405LN fits directly into a door prepped for a Yale 5405LN without modification. Parts interchange including levers, springs, cylinders, and strikes.
What access control platforms work with the 5402LN electrified variants?
Any standard 12V or 24V DC access control: PDK.io, Openpath, Brivo, S2, Genetec, LenelS2, Honeywell Pro-Watch, Kantech, CCure. The 5402LN-EU is fail-secure for card-reader entries; 5402LN-EL is fail-safe for stairwell reentry. Add RX for egress logging and LX latchbolt monitor for closed-door confirmation. Medeco high-security cylinder retrofit works on electrified variants — useful for controlled-drug access or high-security storage with access control.
How does 5400LN compare to the 8800 mortise lock in the same ACCENTRA lineup?
5400LN is a cylindrical lock — standard 2-1/8" cross-bore prep, simpler function set, 10-15 year service life, spec'd for interior office/classroom/storeroom doors. 8800 is a mortise lock — rectangular pocket in door edge, 40+ functions, integrated deadbolt, 15-20+ year service life, spec'd for entry doors and high-traffic institutional. Both share the GA keyway and Para® patented keyway options, so they master-key together cleanly in the same building.
