BEST 45HZ0-NV-3KP-626 – Frequently Asked Questions

1) What door prep does the BEST 45HZ mortise lock need, and will it drop into an existing mortise pocket?
The 45HZ needs a 2-3/4 inch backset mortise pocket. The case measures 5-7/8 x 7/8 x 4-1/16 inches, the faceplate is 8 x 1-1/4 x 1/16 inches, and the escutcheon is 10-1/2 x 3-5/16 x 1 inch (1 inch at the top sloping to 3/4 inch at the bottom). If the existing pocket was cut for a 2-3/4 inch backset mortise lock, the case will go in; the escutcheon footprint and the keypad wiring route are what you need to check next, since the electronic trim covers more of the door face than a plain rose.
2) What does the NV Latch No Key Override function on the BEST 45HZ actually do?
NV is a latch-only function with no key override. Access is by keypad code, and there is no mechanical key that will retract the latch from outside if the electronics are down or a code is forgotten. On an opening where somebody needs to get in with a key regardless, pick a version with a cylinder override instead. The 45HZ NV does still include a 1 inch stainless deadbolt alongside the 3/4 inch stainless latchbolt.
3) Do I have to specify handing when I order the BEST 45HZ keypad lock?
Handing is a required selection: right hand, left hand, right hand reverse, or left hand reverse. Order it to match the opening. The latchbolt itself is oil-impregnated and field reversible without opening the case, and the auxiliary bolt and the strike are both non-handed, so a handing mix-up on site is recoverable rather than fatal.
4) I need a keypad mortise lock with a key override. What should I look at instead of the BEST 45HZ NV?
The 45HZ NV function is latch with no key override, so if a mechanical bypass is a requirement it is the wrong part. The Accentra NTM623-NR nexTouch Generation 3 mortise lock is a Grade 1 keypad unit with cylinder override and no deadbolt. Schlage's CO-100-MS-40-KP is a standalone keypad mortise lock, Grade 1 heavy duty, in privacy function for 1-3/4 inch doors. Both are keypad mortise locks like the 45HZ but resolve the override question differently.
5) I am replacing a mechanical mortise lock with a keypad. Does the BEST 45HZ use the same door prep?
If the lock coming out is a 2-3/4 inch backset mortise lock, the pocket and the 2-3/4 inch backset match, and the ANSI A115.1 strike prep in the frame carries over. Comparable mechanical mortise locks on the same 2-3/4 inch backset include the Hager 3800 Series and the Sargent 4870 Series deadbolt. The two things that change on the swap are the door face, since the 10-1/2 x 3-5/16 inch escutcheon is larger than a rose, and the deadbolt pocket, which the 45HZ needs for its 1 inch throw.
6) What is the closest equivalent to a BEST 45HZ standalone keypad mortise lock from another manufacturer?
The Schlage CO-100-MS-40-KP is the nearest peer: a standalone electronic mortise lock with a keypad reader, listed Grade 1 heavy duty for 1-3/4 inch doors. The difference is function - the Schlage CO-100 in that configuration is a privacy function, while the BEST 45HZ NV is a latch no key override function. The Dormakaba E-Plex 2066 is another standalone electronic pushbutton keyless mortise lock, catalogued for wide stile doors. All three are keypad-operated mortise locks that run without a network head end.
7) I need a keypad mortise lock that still opens with a key if the battery dies - what should I order instead of the 45HZ NV?
The NV function is latch no key override, so there is no mechanical key path on that configuration. For an opening that needs a key bypass, the Accentra NTM623-NR nexTouch Generation 3 mortise lock is a capacitive touchscreen keypad lock with cylinder override and no deadbolt. The Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card entry/egress mortise lock in a back to back arrangement. Confirm the override cylinder keyway matches the rest of the building before ordering.
8) We want credential badges instead of a keypad on a mortise lock - what replaces the BEST 45HZ?
The BEST 45HZ is a keypad-entry lock, so for card or fob credentials look at the RFID peers. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology for 1-3/4 inch doors, and the FME-4000 is the electronic intruder classroom version with RFID. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. Same 1-3/4 inch door prep territory on the TownSteel units, different credential entirely.
9) Will a Schlage L9092EU electric mortise lock do the same job as a BEST 45HZ keypad lock?
No - it is a different control model. The Schlage L9092EU 03A is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, heavy duty for 1-3/4 inch doors. It is switched by an external access control system and needs power run to the door. The Command Access ML190 is similar in concept: a motorized mortise lock with field selectable EL/EU operation on 24VDC, heavy duty storeroom function. The BEST 45HZ carries its own keypad and credentials at the door.
10) Our classrooms need lockdown from inside - is the 45HZ NV the right choice or should I look at another lock?
The NV function is latch no key override, which is not a classroom security arrangement. For classroom lockdown, the Marks USA LA318GJ is a classroom security indicator mortise lockset with an ANSI strike and a steel escutcheon measuring 8-1/2 inch H x 2-3/4 inch W x 7/16 inch, Grade 1 for 1-3/4 inch doors. The TownSteel FME-4000 is an electronic intruder classroom mortise lockset with RFID, Grade 1 heavy duty for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 mechanical classroom mortise lockset with auxiliary deadlatch.
11) Does the BEST 45HZ come with a core, and will it take our existing BEST keys?
Two cylinder housings are offered. The 7-pin housing accepts all BEST cores, so a facility already keyed on a BEST small format interchangeable core system can drop its own core in and stay on the existing keyway. The less core housing ships without one. The standard prep is SFIC less core either way, so the core is bought separately and keyed to your system.
12) What lever styles are available on the BEST 45HZ, and which ones return to the door?
Seven lever choices: 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. Styles 3, 14 and 15 return to within a minimum of 1/2 inch of the door surface; 12, 16 and 17 do not return. If your facility standard calls for a returned lever, order 3, 14 or 15. Levers come in brass, bronze or stainless steel base material.
13) What is the difference between the KP and KG trim on the BEST 45HZ keypad lock?
KP is the keypad alone. KG adds an inside trim passage toggle button, which lets staff hold the outside lever in passage from the secure side, so a room can be left open during business hours and toggled back to locked without touching the keypad programming. On a classroom, conference room, or a retail back-of-house door that swings between open and secure daily, KG is the one to order.
14) What are the alternatives to the BEST 45HZ if I want card or mobile credentials instead of a keypad code?
The 45HZ is code-entry only. For credentials, the TownSteel FME-2000 Series is a Grade 1 classroom mortise lockset with RFID for 1-3/4 inch doors, and the Dormakaba LX-I-M002 Saffire is an RFID mortise lockset with BLE mobile access at BHMA Grade 2. Schlage's LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt, listed with a 3 hour fire rating. Pick by how you intend to issue and revoke credentials, because that is the real operating difference, not the lock body.
15) Should I run a standalone keypad lock like the BEST 45HZ or a hardwired electric mortise lock?
A standalone keypad lock keeps the credential and the decision in the door, so there is no wire to the frame, no power supply, and no head end. That is the fit for scattered openings, tenant doors, and retrofits where getting power to the frame is the expensive part. If the opening has to release from a fire alarm, an access control panel, or a front desk, you want a wired lock instead: the Command Access ML190 Series is a motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC, and the Schlage L9092EU with 03A trim is an electrically unlocked mortise lock, keyed outside, with request-to-exit, on 12/24VDC.
16) I have 40 doors to standardize on. Can the BEST 45HZ carry the whole building?
For a fleet, the 45HZ standardizes well on three axes: one backset (2-3/4 inches), one strike that is non-handed and ANSI A115.1 so every frame takes the same part, and a 7-pin housing that accepts all BEST cores so every door stays on one master key system. Where doors differ, you change only the trim: KP keypad or KG with the inside passage toggle, and any of seven lever styles in a single finish. Doors thicker than 1-3/4 inches up to 3 inches are handled by specifying thickness on those line items.
17) What do I need to specify when ordering a BEST 45HZ EZ Series keypad mortise lock?
Five things settle the order: handing (RH, LH, RHR or LHR, required), cylinder housing (7-pin accepting all BEST cores, or less core), trim style (KP keypad, or KG with the inside passage toggle button), lever style (3, 4, 12, 14, 15, 16 or 17), and finish. Add door thickness if the door is over 1-3/4 inches, up to 3 inches. The strike comes with the lock. The interchangeable core does not, since the standard prep is SFIC less core.
18) Which keypad mortise lock should I use if I need audit trail and lots of user codes rather than a simple standalone keypad?
The Alarm Lock Trilogy family is the alternative for high user-code counts. The DL3500CR is a Grade 1 electronic mortise lock with 300 user codes and classroom function, and the DL4500 series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad. Both are catalogued for doors 1-5/8 inch to 1-7/8 inch thick, so verify door thickness before substituting - the BEST 45HZ standard configuration is built for 1-3/4 inch doors with a thick door option up to 3 inch.
19) Is there a networked or wireless version of a keypad mortise lock instead of a standalone one?
Yes. The Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock with a keypad, built for Adams Rite deadlatches. The Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile-enabled deadbolt with LED, Greenwich trim, right hand, and carries a 3 hour fire rating. Both report to a system head end, where the BEST 45HZ is programmed at the door.
20) If the opening does not really need electronics, what mechanical mortise lock covers the same door prep?
For a 2-3/4 inch backset mortise pocket, the mechanical peers are straightforward. The Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, which pairs with the same interchangeable-core keying approach as the 45HZ SFIC prep. The Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever, and the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors.
21) Can I substitute a Sargent 4874 or Kaba Ilco 185 mortise deadbolt for a keypad mortise lock?
Those are deadbolt bodies, not latching locksets. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, and the Kaba Ilco 185 Series is a non-handed mortise deadbolt. Neither carries a lever or a latchbolt, so the door will not latch on closing. The BEST 45HZ NV carries a 3/4 inch throw stainless latchbolt plus a 1 inch deadbolt throw in one case. If a keypad-controlled deadbolt is what you actually want, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with a privacy keypad.
22) What looks like a substitute for an electronic keypad mortise lock but will not work as one?
Watch for trim and thumbturn items that share the mortise name. The Sargent 130KB and 130W are mortise thumbturns, standard duty, not locks. The Schlage L0170 is a half dummy trim, Grade 1 mortise non-keyed lever with no operating function, and the Falcon MESC600DT is dummy escutcheon lever trim for M9900 exit devices. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets in the dummy function are decorative trim as well. None of these latch or control access.
23) I need a mortise lock on a door thicker than 1-3/4 inch - which options handle that?
The BEST 45HZ has a thick door configuration for doors up to 3 inch thick; specify the thickness when ordering. Among the peers, the Hager 3810E and 3810S 3800 Series Grade 1 passage mortise locks cover 1-3/4 inch to 2-1/2 inch with a 2-3/4 inch backset, and the Baldwin 6301 entry/apartment mortise lock body is catalogued for 1-3/4 inch and over with a 2-1/2 inch backset. Note the Baldwin backset differs from the 2-3/4 inch prep on the 45HZ.
24) For a behavioral health or hospital door, is a keypad mortise lock like the 45HZ appropriate?
Those openings usually call for anti-ligature trim rather than a keypad and escutcheon. The TownSteel MRX-A-01 is a satin stainless steel ligature resistant arch trim mortise lockset in passage function, Grade 1 heavy duty for 1-3/4 inch doors, and the MRX-L-01 is the stainless steel anti-ligature lever version. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
25) Which mortise lock matches an existing BEST small format interchangeable core keying system?
The BEST 45HZ ships with SFIC prep less core, and can be ordered with a 7-pin housing that accepts all BEST cores or a less core housing. If you need a mechanical lock on the same keying system, the Cal-Royal NM8080 Grade 1 storeroom mortise lockset offers an interchangeable core option for 1-3/4 inch doors. Verify the core format with the keying schedule before committing a fleet order.
26) Can I match the BEST 45HZ to the finish on the rest of my doors?
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 satin chrome is the usual commercial standard. 626AM is the one to specify for healthcare or food service where an antimicrobial coating is part of the spec.
27) Is the BEST 45HZ tough enough for a high traffic commercial opening?
The case is 0.095 inch cold rolled steel with zinc dichromate plating for corrosion protection, and the latchbolt, deadbolt and auxiliary bolt are all solid stainless steel. It is a commercial-rated lock, not a residential one. The steel case plus a 1 inch deadbolt is the construction you want on a corridor, stairwell, or tenant entry that cycles all day.
28) Is there a lighter duty electronic mortise latch for an interior or low traffic door?
The Codelocks CL2255 is an electronic tubular mortise latch in a brushed steel finish, catalogued as medium duty in the CL2000 Series. It is a latch-only electronic unit for openings that do not need the heavy commercial case work. The BEST 45HZ uses a 0.095 inch cold rolled steel case with zinc dichromate plating and a solid stainless latchbolt, which is the construction you want on high traffic openings.
