Sargent 28LC-65G05 KB 26D – Frequently Asked Questions

1) What does office function mean on a Sargent 65G05 lever lock, and is it the right function for a private office door?
Office function means the outside lever can be locked and unlocked by key, and once locked it stays locked until it is keyed back, while the inside lever always retracts the latch for free egress. That is the usual choice for a private office or a suite door where staff want to leave it unlocked all day and secure it on the way out. If you want the outside lever to stay locked at all times and only key in, storeroom function is the one to spec instead.
2) Do I have to order a Sargent 6500 lever handed left or right?
No handing to specify. The 6500 Series cylindrical lever is non-handed, so one part number covers left and right hand openings and you can stock a single lock for a whole building. That also means a lock pulled off one door goes straight onto another swinging the other way.
3) Can I put a Sargent 6500 lock on a fire rated door?
Yes. The 65G05 is UL-cUL fire rated up to 3 hours and complies with NFPA 80, so it can go on a rated opening at that rating or below. The rugged build also passes hurricane code testing including Florida Building Code requirements, which matters on exterior and storm-rated openings in coastal jurisdictions.
4) What cylinder options does the Sargent 6500 come with, and can I order it less cylinder to use my own cores?
Four cylinder choices. Standard is a 6-pin Sargent cylinder. The 60 option takes Sargent large format interchangeable core (FSIC) and ships with a plastic disposable construction core; the 70 option is the same idea for small format interchangeable core (SFIC). LC is less cylinder, which is what you order if a locksmith is supplying the cores from an existing keying system. The construction core versions let the trades key the job temporarily and then drop in permanent cores at turnover without pulling the lock apart.
5) Can Sargent 6500 locks be keyed alike or put on my building master key system?
Yes to both. Keying is a required selection with options for keyed different, keyed alike, master keying, or standard keying, plus a no-cylinder option for less cylinder orders. Keyway choice runs the full Sargent range with LA as the standard, and covers the C, H, L, and R families along with R, RA through RL, S and U. Key systems including Degree, Signature and XC are supported, so a property manager standardizing a building can bring these onto the same system as the rest of the doors.
6) What is the closest equivalent to the Sargent 65G05 office function lever from another commercial brand?
The Falcon B511CP6D is the nearest match: a Grade 2 medium duty cylindrical lever lock in the entry/office function, the same lever-operated bored lock in the same grade and function family as the Sargent 65G05 office function Grade 2 cylindrical lock. The Cal-Royal AG00 entrance lever is another Grade 2 cylindrical lever in the entrance/office family, offered with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, and fitting doors 1-3/8 inch to 1-3/4 inch thick. The difference that decides it is keying: the Sargent runs Sargent keyways such as LA standard, and the Cal-Royal comes in the Schlage C keyway, so pick by the key system already in the building.
7) I need a heavier duty version of the Sargent 65G05 for a high traffic opening. What steps up from it?
The 65G05 is standard duty and ANSI/BHMA Grade 2. For a heavier opening, the Dexter C1000 Series entry/office lever is Grade 1 with a clutching keyed lever and fits doors 1-3/8 inch to 1-3/4 inch, the same range the Sargent covers, so the door prep intent stays comparable. The Falcon T101 is a Grade 1 heavy duty cylindrical lever with pressure release technology but in passage function, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever, fire rated, for 1-3/4 inch to 2 inch doors. Of those, only the Dexter C1000 entry/office keeps the keyed office function.
8) What is the difference between the Sargent 65G05 office lever and a storeroom lever like the Cal-Royal AG05?
Function, not construction. The 65G05 is office function with a single cylinder, meaning the outside lever can be left unlocked for business hours and locked when you want it locked. The Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch; a storeroom outside lever stays locked at all times and is retracted only by key. The Hager 2580 is another Grade 2 storeroom lever, for doors 1-3/8 inch to 2 inch. Order storeroom for a mechanical or supply room that should never be left open, and office for a suite door that gets unlocked each morning.
9) Which lever lock replaces the Sargent 65G05 on a classroom or a door that needs key control from the corridor?
Office function is not classroom function. For a classroom door, the Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, matching the 2-3/4 inch backset the 65G05 offers. The Dexter C1000 classroom lever is the Grade 1 clutching keyed version for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 classroom security version adds inside key control of the outside lever. Classroom function locks and unlocks the outside lever by key only, with no inside button, which is what most school and campus specs call for.
10) Can I keep one keyway across a building if I mix the Sargent 65G05 with other brands?
Not directly. The 65G05 runs Sargent keyways, LA standard plus the C, H, L and R families, and takes Sargent large format interchangeable core, small format interchangeable core, a standard 6-pin cylinder or less cylinder. Several peers are built on the Schlage C keyway instead, including the Cal-Royal AG00 entrance lever and the Cal-Royal AG03 classroom lever, and the Arrow MK33-BD-CS asylum lock is a Schlage C keyway part. Where a Yale or Accentra opening has to accept a Schlage cylinder, the Accentra 107S is a Schlage cylinder adapter kit for Yale hardware. The practical route is to order the 65G05 less cylinder or in an interchangeable core version and populate it with cores from the system already in the building.
11) Which locks match the Sargent 65G05 on fire rated openings?
The 65G05 carries a UL-cUL fire rating up to 3 hours with NFPA 80 compliance. Among the peers, the Corbin Russwin CL3110 Grade 1 vandal resistant passage lever is fire rated for doors 1-3/4 inch to 2 inch, the Falcon K101 Grade 1 heavy duty passage lock is fire rated for doors 1-3/8 inch to 2-1/4 inch, and the Arrow MK02-TA Grade 1 privacy lock is fire rated. Note that all three are non-keyed functions, so on a keyed fire door opening the 65G05 office function is the one that carries both the rating and the key.
12) What door prep does a Sargent 6500 cylindrical lock need?
Modified 161 prep. That is the standard cylindrical bore with an added cut, so most doors already prepped for a commercial cylindrical lock take it with little or no rework. Templates come with the lock for marking the holes, and you set the backset (2-3/8 or 2-3/4) to match what is already bored.
13) Is a Grade 2 lock like the Sargent 65G05 enough for a busy commercial door, or should I step up to Grade 1?
Grade 2 standard duty suits offices, tenant suites, and interior commercial doors with moderate traffic. For a main entrance, a corridor door, or anywhere the door is cycled hard all day, a Grade 1 heavy duty cylindrical lock is the better spend, and options like the Falcon K Series K101 or the Corbin Russwin CL3100 Series are Grade 1 heavy duty cylindrical locks. Note the Corbin CL3100 is rated for 1-3/4 to 2 inch doors, so it will not go on a 1-3/8 inch door the way the 6500 will.
14) Does the Sargent 65G05 lever meet ADA requirements for accessible openings?
Yes. The lever trim is ADA compliant with ICC A117.1 certification, so it satisfies the operable-hardware requirement on accessible routes where a knob would not.
15) If I am putting a Sargent 6500 office lock on a classroom or storeroom door, is it the right function?
No. Office function lets the outside lever be left unlocked, which is wrong for a room that must stay secured. For a storeroom door where the outside lever is always locked, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom lever. For a classroom door, the Cal-Royal AG03 is a Grade 2 classroom lever on a 2-3/4 inch backset, and the Dexter C1000 classroom is the Grade 1 option.
16) Which lever should I order instead of the Sargent 65G05 for a restroom or a bedroom door?
Office function keys from the outside, which is wrong for a bathroom. For privacy, the Hager 2540 is a Grade 2 cylindrical privacy lock with the Withnell lever for doors 1-3/8 inch to 2 inch, the Arrow MK02-TA is a Grade 1 privacy cylindrical lock with a tudor knob for doors 1-3/4 inch to 2 inch and is fire rated, and the Baldwin Estate 5103 privacy lever with the 5048 rose covers the decorative side. Privacy locks push-button from inside and release with an emergency tool from outside instead of a key.
17) Is a Grade 3 lever like the Cal-Royal AUS00 an acceptable substitute for the Sargent 65G05?
They are not the same class of lock. The 65G05 is ANSI/BHMA Grade 2 commercial. The Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body, fitting doors 1-3/8 inch to 1-3/4 inch, and the Callan Artino and Callan Bennett entrance leversets are also Grade 3. If a facility spec or a code review calls out Grade 2, a Grade 3 lever will not satisfy it regardless of how similar the function reads. Where the spec is silent and the door is light traffic, the Grade 3 entrance/office levers serve the same keyed-outside, always-retractable-from-inside pattern.
18) Can I order a passage lever in place of the Sargent 65G05 if the door does not need a key?
Yes, and it is the simpler part. The 65G05 is keyed. If the opening never locks, the Falcon B101 is a Grade 2 medium duty non-handed cylindrical passage lever, the Hager 2510 is a Grade 2 passage lever for doors 1-3/8 inch to 2 inch, and the Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever. All three drop the cylinder and the keying decision entirely. Note that a passage lever cannot be keyed later, so if the room may need to lock at some point, stay with the keyed 65G05, which is also offered as a less cylinder version if you are supplying your own cylinder.
19) Does a dummy lever like the BEST 7KC 1DT work as a match for the Sargent 65G05 on an inactive leaf?
A dummy trim is not a lock and has no latch. The BEST 7KC Series 1DT is a Grade 2 non-keyed single dummy trim, and the BEST 9K Series 1DT is the Grade 1 heavy duty equivalent; both are a lever fixed to the door for pulling only. Use one on the inactive leaf of a pair or on a false door where the 65G05 keyed office lock is on the active leaf. It will not latch, will not lock, and cannot be keyed to the same system.
20) What do I use instead of the Sargent 65G05 if the opening needs to unlock on a credential or a code rather than a key?
The 65G05 is a mechanical keyed lock. For code entry, the Delaney LP250 is a Grade 2 electronic keypad leverlock and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination for doors 1-1/8 inch to 2 inch. For an access control tie-in, the Corbin Russwin CL33903 is a Grade 1 electrified fail safe cylindrical lever running on 12VAC/DC for doors 1-3/4 inch to 2 inch, which unlocks on loss of power. Confirm your egress and fire strategy before choosing fail safe, since it releases the outside lever when power drops.
21) Will a residential grade lever like the Kwikset 200BRNL Breton hold up where a Sargent 65G05 is specified?
They are aimed at different traffic. The Kwikset 200BRNL Breton is a Grade 3 passage lever for doors 1-3/8 inch to 1-3/4 inch and the 300BRNL Breton is the Grade 3 privacy version; neither is keyed for an office opening. The 65G05 is a Grade 2 commercial office function lock in standard duty construction. On a tenant unit interior door where nothing needs to lock with a key, the Kwikset passage lever covers it. On a suite entrance carrying a commercial spec, the Grade 2 keyed lock is the one that answers the specification.
22) I want a lever instead of a knob for ADA compliance. Which knob locks in the same functions should I avoid?
The 65G05 is a lever handle lock and is ADA compliant to ICC A117.1. Knob-operated cylindrical locks in the same catalog will not meet that requirement on an accessible route: the Arrow RL Series HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob for doors 1-3/8 inch to 1-3/4 inch, the Arrow MK33-BD-CS asylum lock is a heavy duty ball knob, and the Arrow MK02-TA privacy lock is a tudor knob. If the door is on an accessible path, order a lever, and the 65G05 comes in B, L and P lever styles.
23) Do I have to specify handing when cross-shopping the Sargent 65G05 against other lever locks?
Not with the 65G05, which is non-handed and installs either way. Some peers are the same: the Falcon B101 and the Falcon K101 are both non-handed lever locks. Others are handed and must be ordered to the door swing, such as the Baldwin Estate 5103 half dummy, which comes as a distinct left hand and right hand part. Confirm the swing before ordering any handed lever, since a handed part cannot be flipped in the field.
24) What finishes and lever styles can I get on a Sargent 6500 leverset?
Seven finishes: 03 bright brass clear coated, 04 satin brass clear coated, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 26 bright chrome over nickel, 26D satin chrome over nickel, and BSP black suede powder coat. Three lever designs, B, L and P. For a facility standardizing across openings, 26D is the usual commercial default and it is the one to match if the rest of the building is satin chrome.
25) How many keys come with a Sargent 65G05?
Two keys ship with the lock. It is a single cylinder keyed lock, keyed on the outside only, so if you are turning over a suite to a tenant and need more than a pair, plan the key count into the keying order rather than the lock order.
26) Does the Sargent 6500 need a matching dummy or passage lever for the other doors in the same office suite?
For non-locking openings in the same suite you would pair the keyed office lock with a passage or dummy lever in a matching finish. Cross-brand, the Falcon B101 is a Grade 2 non-handed cylindrical passage lever and the BEST 7KC Series 1DT is a Grade 2 single dummy trim lever. Matching lever design and finish across the suite is what makes a retrofit look intentional rather than patched.
27) Is a decorative lever like the Deltana Manchester or Baldwin Estate 5103 interchangeable with the Sargent 65G05?
They serve different specs. The Deltana 6201 Manchester, 6411 Morant and 6431 Linstead entry levers fit doors 1-3/8 inch to 2 inch and the Baldwin Estate 5103 is offered as a passage lever, a privacy lever and left and right hand half dummies on the 5048 rose. Those are residential entry and trim products chosen for appearance. The 65G05 is a commercial Grade 2 non-handed office function lock certified to ANSI/BHMA A156.2 Series 4000. Use the decorative levers where the look drives the choice and no commercial grade is called out; use the 65G05 where a submittal names a grade.
