BEST 45HZ7-DV-15KP-626 – Frequently Asked Questions

1) Will the BEST 45HZ mortise lock drop into my existing 2-3/4 inch backset mortise prep and strike?
The 45HZ runs a 2-3/4 inch backset, the standard commercial mortise backset, with a case measuring 5-7/8 x 7/8 x 4-1/16 inches and an 8 x 1-1/4 x 1/16 inch faceplate. The latchbolt throws 3/4 inch and the deadbolt throws a full 1 inch, so your frame prep has to accommodate a deadbolt pocket, not just a latch. A universal non-handed strike, 4-7/8 x 1-1/4 x 3/32 inches to ANSI A115.1, ships with the lock. If your existing frame is ANSI A115.1 prepped, the supplied strike matches it. Bear in mind the escutcheon is 10-1/2 x 3-5/16 x 1 inch, so the door face has to be prepped for the keypad escutcheon regardless of how good the pocket is.
2) Does the BEST 45HZ keypad lock come with a core, or do I have to order the cylinder separately?
The 45HZ is a small format interchangeable core lock supplied prepped less core as standard, so plan on providing the core. Two housing choices exist at order time: a 7-pin housing that accepts all BEST cores, or a less core housing. If your building is already keyed on a BEST SFIC system, the 7-pin housing lets you pin your existing core straight in and keep the master key hierarchy intact on the key override side.
3) What does the DV latch with key override function actually do on the BEST 45HZ?
Latch with key override means the outside lever stays locked and is released by a valid keypad code, with a mechanical key in the interchangeable core as the fallback when the electronics are down or a code is forgotten. It runs standalone, one door at a time, with no external controller or head-end wiring. The 1 inch deadbolt is thrown separately, so the keypad governs day-to-day passage while the deadbolt handles lockdown.
4) My door is 1-5/8 inch thick - can I still use a BEST 45HZ electronic keypad mortise lock?
The 45HZ standard configuration is designed for 1-3/4 inch doors, with a thick door configuration available for doors up to 3 inch when the thickness is specified at ordering. For a thinner leaf, the Alarm Lock Trilogy family lists a door thickness range of 1-5/8 inch to 1-7/8 inch across the DL2700CR classroom, the DL3500CR classroom, and the DL4500 Series electronic mortise deadbolt with 2,000 user codes and privacy keypad, all Grade 1. Ornamental iron openings are different again - the Marks USA 21AC and 22AC entrance double cylinder mortise locks are listed for 1 inch doors.
5) Which electronic mortise lock should I use on a classroom door instead of the 45HZ latch with key override?
The 45HZ is built around a latch with key override function, which is not a classroom function. For a classroom opening, the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with classroom function and 300 user codes, and the DL2700CR Trilogy T2 is a Grade 1 electronic mortise lock with classroom function in a weatherproof design. Both are listed for doors 1-5/8 inch to 1-7/8 inch thick. TownSteel offers the FME-2000 Series, a Grade 1 heavy duty classroom mortise lockset with RFID, and the FME-4000 Series electronic intruder classroom mortise lockset with RFID, both for 1-3/4 inch doors.
6) What is the closest alternative to the BEST 45HZ keypad mortise lock from another brand?
The Dormakaba E-Plex 2066 is the nearest match in concept - an electronic pushbutton keyless mortise lock in the E-Plex 2000 Series, operating standalone from a keypad the same way the 45HZ does. The Schlage CO-100 is another standalone electronic mortise lock with a keypad reader, listed as Grade 1 heavy duty in the CO Series. Where they part company is the credential path behind the keypad: the 45HZ carries a key override function and takes an SFIC prep, so a BEST core can be dropped in for mechanical entry, while the Dormakaba E-Plex 2066 is described as keyless. The Accentra NTM623-NR nexTouch Generation 3 mortise lock also pairs a keypad with a cylinder override, using a capacitive touchscreen instead of mechanical pushbuttons.
7) Does the BEST 45HZ report to an access control system, and what do I use if I need networked or credential-based access?
The 45HZ operates standalone as a one-door access control system without external controllers or complex wiring, programmed at the keypad. If the doors need to report back or accept credentials beyond a code, the Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock with keypad built for Adams Rite deadlatches. The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt with LED, in Greenwich trim, right hand, rated 3 hours for fire. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Dormakaba E-Plex E5086 combines pushbutton and card in a back to back Grade 1 mortise lock with entry/egress function.
8) What looks like a substitute for a BEST 45HZ keypad mortise lock but will not work as one?
Several mortise products carry keypads or electronics without doing the same job. The Alarm Lock DL4500 Series is an electronic mortise deadbolt with a privacy keypad - a deadbolt function, not a keyed latch, so it will not retract a latchbolt for normal traffic the way the 45HZ latch with key override does. The Codelocks CL2255 is an electronic tubular mortise latch in the CL2000 Series rated medium duty, a lighter platform than a heavy commercial opening calls for. The Command Access ML190 Series is a motorized mortise lock with field selectable EL/EU operation on 24VDC, which needs a power supply and an upstream access control decision rather than a keypad at the door. And the Schlage L9092EU 03A electric lock/unlock outside lever mortise lock with request to exit runs on 12/24VDC as a corridor function on 1-3/4 inch doors, again controlled remotely rather than by code.
9) Will a BEST 45HZ work on an aluminum storefront or glass door?
The 45HZ is built on a mortise case 5-7/8 inch H x 7/8 inch D x 4-1/16 inch W with a 2-3/4 inch backset for doors 1-3/4 inch thick, which is a hollow metal or wood door pocket rather than a narrow stile. For aluminum openings, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock with keypad is made for Adams Rite deadlatches, and the Dormakaba E-Plex 2066 is listed as wide stile. All-glass doors take a different part entirely - the Kaba Ilco BR Series is a glass door bottom rail lock.
10) Which lever styles on the BEST 45HZ return to the door, and does that matter for code?
Lever styles 3, 14, and 15 return to within a minimum of 1/2 inch of the door surface. Styles 12, 16, and 17 do not return. Round knob is offered as style 4. Returned levers are what specifiers usually call for on egress and accessible openings because a non-returning lever can catch clothing or a bag; if your facility standard calls for a returned lever, order 3, 14, or 15.
11) Should I use a standalone keypad mortise lock like the BEST 45HZ or a networked electronic lock?
Standalone is the right call when you have a handful of doors, no access control head end, and no appetite for running wire. The 45HZ programs at the door and needs no controller. Go networked when you need audit trails pulled centrally, credentials revoked instantly across a campus, or lockdown from a console. For that, ZenSupply carries the Alarm Lock DL1300NW Trilogy Networx wireless mortise lock, the Schlage Electronics LEMD-GRW ENGAGE Series wireless mortise lock with a 125kHz proximity reader, and the Dormakaba LX-I-M002 Saffire RFID mortise lockset with BLE mobile access.
12) What are the alternatives to the BEST 45HZ if I need a pushbutton mortise lock on a thicker or thinner door?
The 45HZ standard build is a 1-3/4 inch door lock, with thick door builds to 3 inches ordered by stated thickness. If your doors sit in the 1-5/8 to 1-7/8 inch band, the Alarm Lock Trilogy line is specified for exactly that range: the DL2700CR T2 classroom mortise lock, the DL3500CR Grade 1 with 300 user codes, and the DL4500 Grade 1 electronic mortise deadbolt with 2,000 user codes. All three are keypad locks. Other 1-3/4 inch pushbutton options include the Dormakaba E-Plex 2066 and the Schlage CO-100 standalone keypad mortise lock.
13) Do I need to run power or wire to install a BEST 45HZ EZ Series keypad lock?
No head-end wiring is required. The 45HZ works as a one-door access control system on its own, without external controllers. Installation is the mortise pocket, the trim, and programming the codes and key override at the door. If you are replacing a hardwired electric mortise lock and want to keep the wiring approach, the Command Access ML190 motorized mortise lock runs on 24VDC with field selectable fail safe or fail secure operation, and the Schlage L9092EU with request to exit is a 12/24VDC electrified mortise lock.
14) I do not need electronic access control - what is the mechanical equivalent of a 45HZ mortise lock?
For a keyed mortise lock without the keypad, the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option, which suits a site already keyed to a small format core the way the 45HZ SFIC prep does. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors. The Cal-Royal NM8050 covers the office/entrance function with an auxiliary deadlatch, Grade 1, for 1-3/4 inch doors. All of these are credential-by-key only, so audit trails and user codes are not part of the picture.
15) Which mortise lock takes battery power without a hardwired supply as an alternative to a keypad lock?
The Dormakaba PowerPlex P2066 Series is a mortise lock in the PowerPlex 2000 Series, and the Dormakaba E-Plex 2066 covers the same wide stile mortise footprint as an electronic pushbutton keyless lock in the E-Plex 2000 Series. The 45HZ itself is a standalone one-door system that does not require external controllers or complex wiring, and it is UL listed under GYQS for electrically controlled single point locks on 3-hour A label doors in both the U.S. and Canada - worth confirming against the peer you pick if the opening is a rated one.
16) Is there a simpler mortise lock for an interior door that does not need a code or a key?
Yes - where the opening only needs latching and free passage, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating. The Hager 3810E is a Grade 1 passage mortise lock with escutcheon on a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, and the 3810S is the same passage function with a rose. That 2-3/4 inch backset matches the 45HZ backset, so the mortise pocket layout carries over. Schlage's PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. None of these secure the door - they are for openings where the electronic credential is not wanted at all.
17) What do I use instead of a keypad mortise lock on a restroom or patient room where privacy is the requirement?
The Schlage CO-100 standalone electronic mortise lock is offered in a privacy function with a keypad reader, Grade 1 heavy duty in the CO Series for 1-3/4 inch doors, which keeps the electronic platform while changing the function. Mechanically, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. In behavioral health settings the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function and the MRX-A-01 is the arch trim ligature resistant version, both for 1-3/4 inch doors.
18) How does the BEST 45HZ compare with the Schlage LE Series mobile-enabled mortise lock?
Both put the credential at the door. The Schlage Electronics LEBMB-ADD is a mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, listed Grade 2 for 1-3/4 inch doors with a 3 hour fire rating. The BEST 45HZ is a latch with key override function on a 0.095 inch cold rolled steel case, UL listed under GYQS for 3-hour A label doors in the U.S. and Canada, with a 3/4 inch stainless steel latchbolt and 1 inch deadbolt throw. The 45HZ takes an SFIC prep so a BEST core covers mechanical entry; the LEBMB-ADD is credentialed by push button and mobile.
19) Can a Baldwin or Emtek mortise lock body replace a BEST 45HZ on a commercial opening?
They are built for a different opening. The Baldwin 6301 entry/apartment and 6310 entry/storeroom mortise lock bodies are on a 2-1/2 inch backset, while the BEST 45HZ uses a 2-3/4 inch backset, so the mortise pocket and cylinder centerline do not line up. The Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane are dummy function mortise entrance locksets, meaning trim only with no latching mechanism. For a commercial replacement with matching backset geometry, the Hager 3850E Grade 1 office mortise lock with lever and escutcheon uses a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch.
20) I only need a deadbolt on this door, not a full electronic lockset - what mortise deadbolt options are there?
The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset in the 4870 Series, the same backset the 45HZ uses, so it sits in comparable pocket geometry. The Kaba Ilco 185 Series is a no-handing mortise deadbolt sold in a single pack. If the deadbolt needs to be code-operated, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for doors 1-5/8 inch to 1-7/8 inch. The 45HZ integrates its own 1 inch throw stainless steel deadbolt alongside the latchbolt rather than running as a separate deadbolt.
21) Is there an alternative to a keypad mortise lock for a dormitory or corridor door with a deadbolt?
The Sargent 7925 is a dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, Grade 1 heavy duty - the mechanical route for corridor and dormitory openings. For classroom security with visual status, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset in the LA318 Series with an ANSI strike and a steel escutcheon measuring 8-1/2 inch H x 2-3/4 inch W x 7/16 inch, for 1-3/4 inch doors. The BEST 45HZ escutcheon runs 10-1/2 inch H x 3-5/16 inch W x 1 inch deep, so the trim coverage on the door face is not interchangeable between them.
22) Can I get the BEST 45HZ keypad mortise lock in a finish to match the rest of my building?
Twelve finishes are offered: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial, and 690 statuary dark bronze. 626 is the workhorse on commercial openings. The 626AM antimicrobial variant is worth a look on patient rooms and food service doors where touch surfaces are part of the spec.
23) Is the BEST 45HZ mortise lock case durable enough for a high traffic commercial entrance?
The case is 0.095 inch cold rolled steel, zinc dichromate plated for corrosion protection. Latchbolt, deadbolt, and auxiliary bolt are all stainless steel, and the latchbolt is oil-impregnated so it runs against the strike without galling. That is a heavy duty mortise platform under the electronics, which is the part that usually decides whether an electronic lock survives a busy corridor.
24) What is the difference between the BEST 45HZ keypad trim options and a push/pull paddle mortise set?
The 45HZ trim comes as KP keypad or KG keypad with an inside trim passage toggle button, with lever styles including 3 solid tube with return, 12 solid tube no return, 14 curved with return, 15 contour with angle return, 16 curved without return, 17 gull wing, and 4 round knob. Where hands-free egress matters, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in the 195 Series, ligature resistant and ADA compliant in satin stainless steel - a paddle operation rather than a lever, and passage rather than credentialed entry.
