Corbin Russwin ML2000 Mortise Locks
Grade 1 heavy-duty mortise lock series with patented Quick Reversible latchbolt, 1" stainless steel deadbolt, 63 mechanical and electrified functions, and a 10-year warranty. The Corbin Russwin specification of choice for high-traffic educational, healthcare, government, and institutional doors.
Parent company: ASSA ABLOY (Corbin Russwin, Inc.)
About Corbin Russwin ML2000
The Corbin Russwin ML2000 Series is an ANSI/BHMA A156.13 Grade 1 mortise lock built by ASSA ABLOY for the kind of openings that see thousands of cycles a day — K-12 classroom doors, hospital corridors, government building entries, and multi-tenant commercial offices. Constructed of heavy-gauge steel with a patented Quick Reversible latchbolt (re-hand without disassembling the lockbody), 1" throw stainless steel deadbolt, and 3/4" anti-friction latch, the ML2000 is engineered for 10-year service life with minimal maintenance.
What sets the ML2000 apart from every other mortise lock on the market is the universal lockbody design. The ML2054 entry/office function (ANSI F04) can be reconfigured in the field to 11 other functions without removing the lock case from the door — a major advantage for facility managers who need to change door behavior (e.g., convert a classroom to a storeroom) without stocking multiple lockbodies. Corbin Russwin also offers the ML2000VR (Vandal Resistant) for abuse-prone environments and ML2000HS (High Security) with Access 3® or Pyramid patented key systems for environments where key control matters — multi-family, cannabis retail, government, pharmaceuticals.
Key-En-Lock services the full ML2000 lineup across Brevard County. We stock the most-specified lever designs and finishes on the truck, handle field rekeys to IC or conventional cylinders, and service the electrified ML20900 / ML20906 / MELR variants that tie into PDK.io, Openpath, and other access control platforms. For behavioral health facilities we install the BHSS and HSS anti-harm trim — Corbin Russwin is one of the few manufacturers offering a Grade 1 mortise lock with a recessed, anti-ligature knob certified for psychiatric units.

Electrified & Access Control Variants
Modern commercial buildings tie mortise locks into card readers, mobile credentials, and access control panels. Corbin Russwin ML2000 offers a full electrified lineup for card-reader exits, stairwell reentry (IBC 1010.1.9.12), and fail-safe vs fail-secure configurations.
- ML20906 — Fail-secure outside lever: Power unlocks the outside lever; power loss keeps it locked. The standard for card-reader entries (office, retail, multi-family). 12V DC or 24V DC.
- ML20900 — Fail-safe outside lever: Power keeps it locked; power loss unlocks. Required for stairwell reentry doors under IBC 1010.1.9.12 and for fire corridor doors where fire alarm drops power.
- MELR (Motorized Electric Latch Retraction): A motor retracts the latchbolt on command — replacing older solenoid retractors. Low current draw, quiet operation, and compatible with auto door operators, card readers, and touchless entry.
- EcoFlex® technology: Corbin Russwin's energy-efficient electronics — up to 89% less power than comparable electrified mortise locks. Reduces PoE and power supply load.
- RX (Request-to-Exit) monitoring: Built-in microswitch signals access control system when inside lever is operated, logging egress events.
- LX (Latchbolt Monitor): Senses latchbolt position — confirms door is actually latched when closed, critical for secured storerooms and healthcare controlled drug rooms.
- DPS (Door Position Switch): Built-in door open/closed sensor eliminates separate magnetic contact — cleaner install, fewer failure points.
- SN200-ML2000: Wiegand-compatible integrated reader + lock combination. Migration path from legacy card systems to mobile credentials.
Fire Rating & Code Compliance
- UL Listed for use with fire-rated doors up to 3 hours (except ML2020 privacy).
- Field-reversible latchbolt does NOT void fire rating — Corbin Russwin certifies reversal in field.
- Fire-rated installations require standard ANSI straight lip strike (4-7/8" x 1-1/4" x 1-1/8" lip to center) with dust box.
- Florida Building Code accepts UL 10C labeled mortise locks on A-label (3-hour) fire doors — verify label during every fire door inspection.
- Electrified variants (ML20906/ML20900) maintain UL fire rating when wired per Corbin Russwin spec.
- BHSS / HSS behavioral health trim options are UL-listed for fire doors — rare among anti-ligature hardware.
Common Corbin Russwin ML2000 Repairs We Service
After 25+ years of commercial locksmith work in Brevard County, these are the failure modes we see most often on Corbin Russwin ML2000 mortise locks. All are truck-serviceable — we don't need to take the door off its hinges.
- Lever sag or spring back failure — worn torsion spring in the spindle assembly, most common ML2000 failure after 5+ years of heavy use. On-site spring kit replacement, no disassembly from door required.
- Cylinder won't turn / key binds — cam alignment drifted or cylinder retainer screw loose. Cam repositioning on-site; if cylinder itself is worn, swap to a new CR-compatible 1-1/8" mortise cylinder.
- Deadbolt stuck in extended position — usually door sag has misaligned strike; re-shim strike or adjust hinges. Occasionally a bent deadbolt; replace.
- Latchbolt won't retract when lever turned — internal drive cam worn or lever hub slipping. Lockbody rebuild with OEM kit or full lockbody swap.
- ML20906 electrified lock not releasing — solenoid failure, voltage drop from long wire run, or access control relay issue. We test voltage at the lock, troubleshoot wiring, and replace solenoid or full electrified lockbody as needed.
- MELR motor not retracting latch — power supply dip, motor driver board failure, or latchbolt binding. Diagnostic + motor kit replacement on-site.
- Key system rekey (entire building) — we rekey in place using CR 59A1, 60, Access 3®, or Pyramid keyways. Master key + grand master key schemes designed for multi-tenant properties.
- IC core swap — SFIC or CR LFIC cores exchanged in under 30 seconds per door. No lockbody disassembly.
- Behavioral health upgrade (HSS / BHSS) — we retrofit existing ML2000 locks with anti-ligature trim for psychiatric, group home, and detention facility certifications.
- Vandal repair — replacing smashed escutcheons, bent levers, kicked strikes. Full ML2000VR retrofit available for repeat-vandal openings.

Call (321) 224-5625Frequently Asked Questions
What's the difference between ML2000 and ML2000VR?
The ML2000VR (Vandal Resistant) uses heavier-gauge tapered-edge stainless steel escutcheons, Torx pin-tamper-resistant screws, and reinforced internal components. The lockbody itself is the same Grade 1 mechanism — VR is a trim upgrade for abuse-prone environments (school locker rooms, detention, high-crime retail back doors). If you've got a door that gets kicked, pried, or smashed regularly, spec the VR — otherwise standard ML2000 is fine.
Can I rekey an ML2000 to a key I already have?
Yes — the ML2000 accepts any standard 1-1/8" mortise cylinder, so you can rekey to match an existing Schlage C, Kwikset KW1, or other standard keyway just by swapping the cylinder. If you're using the Corbin Russwin 59A1 or 60 keyway, we can rekey the existing cylinder on-site. For patented Access 3® or Pyramid keyways, the cylinder must come from an authorized CR dealer (we are one) and blanks are key-control restricted.
Is the ML2054 really reconfigurable to other functions in the field?
Yes — this is one of the ML2000's headline features. The ML2054 universal lockbody has an internal function-change mechanism that lets us convert F04 entry/office to 11 other functions (storeroom, classroom, privacy, etc.) without removing the lock from the door or ordering a new lockbody. Facility managers stock one ML2054 variant and adapt doors as needs change. Saves ordering time and parts inventory.
Does ML2000 work with PDK.io or other access control?
Yes — the ML20906 (fail-secure) and ML20900 (fail-safe) electrified variants work with any standard 12V or 24V DC access control system including PDK.io, Openpath, Brivo, S2, Genetec, LenelS2, and proprietary systems. The MELR motorized variant is quieter and lower-current than solenoid-based alternatives. For new installations we typically spec ML20906 with RX request-to-exit and LX latchbolt monitor — gives the access control platform full status visibility. We install the lock, run low-voltage wiring, and hand off to your access control vendor or do end-to-end through our PDK.io dealer authorization.
How does ML2000 compare to Schlage L9000 and Sargent 8200?
All three are ANSI A156.13 Grade 1 mortise locks and all three are specified interchangeably by architects. Corbin Russwin ML2000 has the widest function catalog (63 mechanical + electrified) and the unique universal-lockbody field-reconfigure. Schlage L9000 has the widest lever/escutcheon design selection and the strongest Primus high-security keying. Sargent 8200 has the heaviest cast stainless steel chassis — considered the industry durability benchmark — and the best fail-secure/fail-safe electrified implementation. For behavioral health and psychiatric openings, ML2000 wins (BHSS/HSS are best-in-class). For key control and master keying depth, Schlage. For pure abuse resistance, Sargent.
Is ML2000 code-compliant for Florida K-12 classroom security?
Yes — the ML2062 (classroom intruder deadbolt) and ML2057 (classroom security) functions meet current Florida school safety guidance. The ML2062 is the stronger spec: one motion of the inside lever throws both the latchbolt and deadbolt simultaneously, so a teacher can lock a classroom in a lockdown without opening the door or fumbling with a key. This meets Alyssa's Law intent for secure interior egress. Also code-compliant under Florida Building Code and NFPA 101 for free egress (inside lever is always free). We've installed these across multiple Brevard County K-12 and private school retrofits.
How long does an ML2000 mortise lock last in a commercial building?
Corbin Russwin warrants the mechanical lockbody for 10 years. In real-world high-traffic service (school corridor, hospital, office tower), the lockbody typically runs 15-20+ years before needing a rebuild — the Quick Reversible latchbolt and heavy-gauge steel chassis are built for millions of cycles. The most common wear items are the spindle torsion spring (5-10 years) and the cylinder (5-15 years depending on keying system). We service all of these in-field without removing the lock from the door.
