Sargent KP8277-LNB-26D – Frequently Asked Questions

1) Does the Sargent 8277 keypad mortise lock have a key cylinder override?
No. The 8277 is the keypad entry function with no cylinder override, so entry is by code only. If you need a mechanical key override on the same series, you need a different function number in the KP-8200 family. Note that cylinder and keying options are still specified on the order (standard cylinder, 60 Sargent large format interchangeable core less core, or 70 small format interchangeable core less core) for the lock body's keyed side, and Sargent builds the cylinder so it drops into a new or existing master key system.
2) Is the Sargent KP-8200 keypad lockset handed, or will one part work on both left and right doors?
Non-handed. The same 8277 works on a left or right hand opening, which is why a property manager standardizing across a building only has to stock one configuration per finish and lever.
3) Does the Sargent 8277 need to be wired to power or a panel?
No wiring. It's a standalone, battery-powered, motor-driven lock with a microprocessor controller, and all programming is done at the door on the keypad. There's no external controller, no reader wiring, and no power transfer hinge to run. Typical battery set gives about 40,000 operations, and user codes sit in non-volatile memory so they survive a dead battery.
4) Is the Sargent keypad mortise lock rated for high-traffic commercial use?
It's ANSI/BHMA Grade 1 to A156.13, the heavy-duty commercial mortise standard, and the lock is catalogued for commercial service. That's the grade specified for schools, healthcare corridors, government buildings and multi-tenant residential entries.
5) Can I replace an existing Sargent 8200 mechanical mortise lock with the KP-8200 keypad version?
The keypad lock uses the same 7800/8200 Series mortise installation template, including the sectional rose and escutcheon trim preps, so the door pocket carries over. What changes is the outside trim: the keypad unit mounts on the exterior face and you'll be running the keypad connection to the lock body per the wiring diagram, then setting user codes at the door before the opening goes back in service. Verify the existing pocket and strike alignment against the template rather than assuming an older cut matches.
6) What is the closest equivalent to the Sargent 8277 keypad mortise lock from another brand?
The Sargent 8277 is a standalone, battery-powered keypad mortise lockset with ANSI/BHMA Grade 1 certification and entrance/office function. The closest peers are the Schlage CO-100-MS-40-KP, a Grade 1 standalone electronic mortise lock with a keypad reader, and the BEST 45HZ EZ Series electronic keypad mortise lock. The Schlage CO-100 in that configuration is built for privacy function and 1-3/4 inch doors, while the Sargent 8277 is an entrance/office function lock. The Dormakaba E-Plex 2066 Series is another standalone pushbutton keyless mortise lock in the same family of product.
7) What should I use instead of the Sargent 8277 on a classroom door?
The Sargent 8277 is an entrance/office function lock, so for a classroom opening look at a classroom-function electronic mortise lock instead. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with classroom function and 300 user codes for doors 1-5/8 to 1-7/8 inches thick, and the Alarm Lock DL2700CR is a Grade 1 classroom-function Trilogy T2 mortise lock with weatherproof design over the same door thickness range. The TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID credentials on 1-3/4 inch doors.
8) Is there a networked or card-credential alternative to the Sargent 8277 keypad lock?
The Sargent 8277 is programmed entirely at the door from the keypad with no external controller. If the facility wants credentials or a network head end, the Alarm Lock DL1300NW is a Trilogy Networx wireless electronic mortise lock with keypad, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125 kHz proximity reader and mobile-enabled deadbolt, and the Dormakaba E-Plex E5086 is a Grade 1 pushbutton and card mortise lock. The Dormakaba Saffire LX-I-M002 is an RFID mortise lockset with BLE mobile access at BHMA Grade 2.
9) Is a wired electric mortise lock a substitute for the Sargent 8277?
They solve different problems. The Sargent 8277 is standalone and battery powered, rated for roughly 40,000 operations per battery set, so the door needs no power transfer. The BEST 45HW Series is a wired electromechanical mortise lock running on 12V or 24V, 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 03A is a heavy duty electric lock/unlock outside lever mortise lock at 12/24VDC with request to exit. All three require power run to the opening through a hinge or transfer device and an access control panel; the 8277 does not.
10) What looks like a substitute for the Sargent 8277 but will not work on the same door?
Several mortise products sit near the Sargent 8277 without being interchangeable. The Codelocks CL2255 is an electronic tubular mortise latch rated medium duty, a lighter mechanism than the Grade 1 mortise body under the 8277. The Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with privacy keypad, so it has no lever and needs separate latching hardware. The Alarm Lock DL1300NW is built for Adams Rite deadlatches in narrow aluminum stiles rather than a standard mortise pocket, and the Dormakaba E-Plex 2066 is a wide stile product. Emtek dummy mortise locksets such as the 3106 Manhattan do not latch at all.
11) For a behavioral health or ligature-resistant opening, is the Sargent 8277 the right lock?
The Sargent 8277 carries a lever and a surface keypad, which is not a ligature-resistant profile. For those openings the TownSteel MRX-A-01 is a Grade 1 heavy duty ligature-resistant arch trim mortise lockset in satin stainless steel with passage function for 1-3/4 inch doors, the TownSteel MRX-L-01 is the anti-ligature lever version, and 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.
12) What lever and rose choices do I have on the Sargent KP-8200 keypad lock, and what finishes?
Eight lever designs (A, B, E, F, J, L, P and W) and two rose styles, L and LN. Fourteen finishes run from 03 bright brass and 04 satin brass through 10B dark oxidized satin bronze oil rubbed, 14 and 15 nickel, 20D dark statuary bronze, 26 and 26D chrome, plus BSP black suede and WSP white suede powder coat. Pick the lever and finish that match the mechanical 8200 locks already on your other openings so the keypad door doesn't look like an add-on.
13) What function is the Sargent 8277, and is it the right one for an office door?
Entrance/office function. The outside lever is controlled by the keypad code, and it's the usual pick for a tenant suite, office or staff-only door where people need to lock and unlock from the inside and get in by code from the corridor. If you need a classroom function instead, that's a different function number, and comparable classroom electronic mortise locks include the Alarm Lock DL3500CR and the TownSteel FME-2000.
14) What are the alternatives to the Sargent 8277 if I want a key override or a card reader on the same door?
Several standalone electronic mortise locks cover what the 8277 does not. For keypad plus mechanical key override, the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override. For credential-based access instead of codes, the TownSteel FME-2000 Series is a Grade 1 RFID mortise lockset for 1-3/4 inch doors, and the Dormakaba Saffire LX-I-M002 adds RFID with Bluetooth mobile access. For pushbutton keyless with no batteries to change, the Dormakaba PowerPlex P2066 Series is self-powered. The Accentra nexTouch NTM623-NR is a Grade 1 touchscreen keypad mortise with cylinder override and no deadbolt.
15) What do I have to specify when ordering the Sargent 8277 keypad mortise lockset?
Four things beyond finish, lever and rose. Cylinder: standard cylinder, 60 for Sargent large format interchangeable core less core, or 70 for small format interchangeable core less core. Keying: keyed different, keyed alike, a specific key code, or none if you chose a less-core option and your locksmith is supplying cores. If you're keying to an existing system, enter the key code on the order. Order the less-core option when your facility already stocks its own IC cores.
16) We standardize on Sargent mortise hardware - can the 8277 keypad lock go on a storeroom door too?
The Sargent 8277 is built for entrance/office function, so a storeroom opening calls for a storeroom-function lock. Comparable mechanical storeroom mortise locks include the Accentra 8805FL, a Grade 1 storeroom mortise lock with Arcadia lever in the 8800 Series, and the Cal-Royal NM8080, a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. The 8277 itself is offered with Sargent large format (60) and small format (70) interchangeable core prep, so a facility keying to IC cores can carry the same core across both electronic and mechanical openings.
17) If I do not need electronic access control, what is the simpler mortise lock equivalent to the Sargent 8277?
The Sargent 8277 carries a battery-powered, motor-driven keypad on a Grade 1 mortise body. For the same entrance/office opening with a purely mechanical lock, the Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon on a 2-3/4 inch backset, non-keyed, for doors 1-3/4 to 2-1/2 inches thick.
18) Is there a Grade 1 alternative to the Sargent 8277 that runs without batteries?
The Sargent 8277 is battery powered with a typical 40,000 operations per battery set and non-volatile memory that retains user codes through power loss. If the facility wants to avoid battery changes entirely, the Dormakaba PowerPlex P2066 Series mortise lock is the self-powered pushbutton option in this group. For wired power instead, the BEST 45HW Series electromechanical mortise lock operates on 12V or 24V.
19) Does the Sargent 8277 need handing, and how does that compare to other mortise locks?
The Sargent 8277 is non-handed, so one part number covers both hands of door. Among mechanical peers the BEST 45H Series public entrance mortise lock body is field reversible and the Falcon MA101 Grade 1 heavy-duty mortise passage lock is also field reversible. By contrast the Baldwin 6310190RRLS is ordered specifically as right hand reverse, and the Schlage LEMD-GRW ENGAGE wireless mortise lock is specified right hand, so those require the hand to be confirmed at order time.
20) How does the Sargent 8277 compare to the Schlage LE Series mobile-enabled mortise lock?
The Sargent 8277 is ANSI/BHMA Grade 1 with keypad entry and standalone at-the-door programming. The Schlage Electronics LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED covering privacy, office and apartment functions, rated for a 3 hour fire rating on 1-3/4 inch doors. The 8277 is the Grade 1 option; the LEBMB-ADD adds mobile credentialing at Grade 2.
21) What do the LED colors mean on the Sargent KP-8200 keypad?
Green means unlocked, yellow means the lock is in programming mode, and a flashing green with a solid yellow means the deadbolt is thrown. That last one matters on a walk-through: your maintenance tech can tell from the LED whether the deadbolt is out without touching the lever.
22) Will the Sargent keypad hold up mounted on an exterior door in direct sun?
The keypad material is textured and UV-stable, so it resists ultraviolet degradation in outdoor and high-light locations. That's the difference between a keypad that stays legible and one that chalks and fades on a south-facing entry.
23) Is there programming documentation for the Sargent KP-8200 keypad lock?
Yes. Sargent publishes a KP8200 keypad mortise lock programming instruction sheet covering code entry and the user-selectable function settings, and the 7800/8200 Series mortise lock catalog covers the lock body itself. All programming is done at the keypad, so the installer sets master and user codes at the door with no software or laptop.
