Emtek F20-3525-75-RH-FB – Frequently Asked Questions

1) Will the Emtek 3525 mortise entry set fit a standard 1-3/4 inch door?
Yes. The 3525 Rectangular mortise entrance lockset is built for a 1-3/4 inch door as standard, and thicker doors are handled by specifying the thickness when you order rather than by buying a different set. The lock body drops into a standard mortise pocket prepped to ANSI A115.1, so if the door is already mortise-prepped to that standard you are working with existing prep. Backset is 2-1/2 or 2-3/4 inches, so match whichever pocket depth the door has.
2) Do I have to specify handing on an Emtek 3525 mortise lockset?
Handing is required, and there is no field-reversing your way out of it. You pick left or right hand, and also whether the door swings in or out, which gives four handing choices in all. Stand outside the door: the side the hinges are on gives you left or right. Get it wrong and the lever or knob will be upside down and the latch bevel will face the wrong way.
3) What is the difference between the F20 and F13 function on the Emtek 3525 mortise lock?
Two different ways the door behaves. F20 is the entrance function, the normal front door setup where the key retracts the latch from outside and the inside trim always gives free egress. F13 is the dormitory function, used where the outside trim needs to stay locked and be released only by key. Both are ANSI-designated functions on the same 3525 lock body, so you are choosing behavior, not a different lock. Pick F20 for a house or apartment front door, F13 where you want the outside consistently secured.
4) Can I key an Emtek 3525 entry set to my existing Schlage keys?
The 3525 uses the Schlage C keyway, so it takes the same key blank as a standard Schlage residential cylinder and can be keyed into an existing Schlage C system. It is a single cylinder keyed lock, key outside and thumbturn or trim inside. You can order it keyed different or keyed alike across multiple sets, and if you already run a keying code you can supply that code when ordering.
5) Is the Emtek 3525 mortise lock fire rated for a door that needs a fire label?
The 3525 mortise lock is UL Listed with a 180 minute (3 hour) fire rating on the lock body. That covers openings up to a 3 hour label, provided the door, frame and the rest of the opening hardware carry their own labels. The rating is on the mortise lock itself, which is the part inspectors look at on a mortise opening.
6) What comes in the box with the Emtek 3525 entry set, and what else do I need to order?
Sold as a complete set: the mortise lock body, latch and strike plate, plus the exterior rectangular trim and the inside knob or lever you choose. The one thing you must decide on the order is the inside trim style, and it is a required choice with roughly ninety knob and lever options across bronze knobs, crystal and porcelain knobs, and levers. Also required is the keying selection. If the door is thicker than 1-3/4 inches, state the thickness so the spindle and screw lengths come right.
7) Should I use an Emtek 3525 mortise entry set or a commercial Grade 1 mortise lock?
The 3525 is a residential product, a solid brass decorative entry set in a rectangular plate with entrance or dormitory function. It is the right call for a house, a townhouse, a condo front door, or a high-end apartment where appearance carries as much weight as the hardware schedule. If the opening is a commercial door on a spec that calls out ANSI/BHMA Grade 1, look at a heavy duty commercial mortise lockset instead: ZenSupply carries the Corbin Russwin ML2003 and the Cal-Royal NM8050 Grade 1 entrance/office mortise lockset, both listed for 1-3/4 inch doors. Those are function-driven institutional locks, not decorative entry sets.
8) What is the closest equivalent to the Emtek 3525 mortise entrance lockset in a decorative brass residential handleset?
The Emtek 3525 is a brass mortise entry set with a 2-1/2 inch or 2-3/4 inch backset and F20 entrance or F13 dormitory function. The nearest peer in a decorative residential mortise body is the Baldwin 6301, an entrance/apartment mortise lock body with a 2-1/2 inch backset offered knob by knob, or the Baldwin 6301LS in the lever by lever version, both listed for doors 1-3/4 inch and over. The Baldwin 6301 pair covers the entrance/apartment function; the Emtek 3525 covers F20 entrance and F13 dormitory and takes a Schlage C keyway.
9) Which mortise locks are field reversible instead of requiring handing like the Emtek 3525?
The Emtek 3525 requires handing to be specified as left or right, in-swing or out-swing, at the time of order. Peers that avoid a handed order include the BEST 45HCAC heavy duty public entrance mortise lock body with field reversible operation, the Falcon MA101 Grade 1 heavy duty mortise passage lock with field reversible operation, and the Kaba Ilco 185 Series mortise deadbolt, which is listed with no handing. Field reversible bodies can be set on site; the Emtek 3525 is built to the hand you specify.
10) I want keypad or card access on a mortise door instead of a keyed brass entry set - what replaces the Emtek 3525?
The Emtek 3525 is a mechanical, non-electronic keyed mortise entry set. For credential-based access on a mortise prep, the Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad and cylinder override with no deadbolt, and the Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. The nexTouch keeps a cylinder override for mechanical key entry; the Saffire is credential and mobile driven.
11) My door is thicker than 1-3/4 inches - which mortise locks list a wider door thickness range than the Emtek 3525?
The Emtek 3525 is built to 1-3/4 inch doors as standard, with thicker doors specified at order. Among mortise peers listed for thicker doors, the Hager 3810E is a Grade 1 passage mortise lock with escutcheon and 2-3/4 inch backset covering 1-3/4 inch to 2-1/2 inch, the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon covering the same 1-3/4 inch to 2-1/2 inch range, and the Baldwin 6301 lists 1-3/4 inch and over. The Hager pair is non-keyed passage and office function, so a keyed entrance opening points back to the Baldwin 6301 or to the 3525 ordered with the door thickness stated.
12) I need a fire rated mortise lock - how does the Emtek 3525 compare to other fire rated options?
The Emtek 3525 is UL listed with a 180 minute fire rating. Among mortise peers with a stated fire rating, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour rating, the LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with a 3 hour rating, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with a fire rating and field reversible operation. The Emtek 3525 is the mechanical keyed brass option; the Schlage LE units are credential-based, and the MA101 is passage function.
13) What is the storeroom function equivalent when the Emtek 3525 entrance function will not work for a service door?
The Emtek 3525 is offered in F20 entrance and F13 dormitory function. For storeroom function on a mortise prep, the Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever in the 8800 Series, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. The NM8080 interchangeable core option suits a facility on its own core system; the Emtek 3525 is supplied in a Schlage C keyway.
14) I need matching hardware on an interior door that does not lock. Is there a non-functioning version of the Emtek 3525?
Yes. Emtek makes the 3125 dummy as the non-operating match to the 3525 rectangular mortise entry set, so you can carry the same rectangular plate and the same knob or lever across a door that needs no latch, like a closet or an inactive leaf of a pair. Same trim family, no lock body.
15) Is there a mortise entry set that works on doors thicker than 1-3/4 inches?
The 3525 handles thicker doors directly. It ships set for 1-3/4 inches, and you state the actual thickness at time of order so the parts are supplied to suit. That is worth knowing on older homes and custom entry doors, where 2 inch and thicker slabs are common. On the commercial side, ZenSupply also carries Hager 3800 Series mortise locks rated for 1-3/4 to 2-1/2 inch doors, and Baldwin 6301 mortise lock bodies listed for 1-3/4 inches and over, but those are function locks rather than decorative entry sets.
16) Can I order several Emtek 3525 entry sets keyed alike for a building?
Keyed alike is one of the two required keying selections, so a run of front doors can all take one key. Keyed different is the other option. Because the cylinders are Schlage C keyway, sets ordered this way also drop into an existing Schlage C masterkey system, and you can supply your keying code on the order. That is the practical route for a landlord standardizing several units on the same decorative entry set.
17) Is a Sargent 4874 mortise deadbolt a substitute for the Emtek 3525 entrance lockset?
No. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset in the 4870 Series - a deadbolt only, with no latch or operating trim. The Emtek 3525 is a keyed single cylinder entry set with F20 entrance or F13 dormitory function, supplied complete with latch and strike plate and an inside knob or lever. A 4874 would be specified alongside separate trim, not in place of a complete entry set.
18) Which mortise lock should I use for a bedroom or bathroom door where the Emtek 3525 entrance function is not appropriate?
The Emtek 3525 is a keyed entry function set. For a bed or bath opening, the Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch. Both are privacy function; the Emtek 3525 is keyed on the outside.
19) The door does not need to lock - what is the non-keyed mortise option next to the Emtek 3525?
The Emtek 3525 is a keyed entry set; the matching non-locking code in the same family is the 3125 dummy. For a functioning non-keyed mortise latch, the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, for 1-3/4 inch doors, and the Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch. A dummy does not latch at all, while the PM010 and 3810S retract a latch with the trim.
20) Are the Marks USA 21AC and 22AC ornamental iron mortise locks an alternative to the Emtek 3525?
They serve a different door. The Marks USA 21AC is an entrance double cylinder Unilock ornamental iron mortise lock with a round knob listed for 1 inch doors, and the 22AC is the same style entrance double cylinder ornamental iron mortise lock in the 22 Series, also listed for 1 inch doors - both built for narrow ornamental iron gates and doors. The Emtek 3525 is a brass entry set for 1-3/4 inch standard wood or comparable doors and is a single cylinder keyed function.
21) Can I use a Schlage PC10 in place of an Emtek 3525?
Only if the door is prepped for a cylindrical lock. The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, for 1-3/4 inch doors - a bored prep, not a mortise pocket. The Emtek 3525 requires standard mortise door prep to ANSI A115.1 and is keyed. Swapping between them means changing the door prep, not just the hardware.
22) What finishes does the Emtek 3525 rectangular mortise entry set come in?
Three bronze finishes: Flat Black Bronze, Medium Bronze, and Tumbled White Bronze. All three are living finishes on solid brass, so they will shift and soften with handling and weather rather than staying uniform out of the box. If you are matching hardware already on a building, that patina behavior matters more than the finish name.
23) Is the Emtek 3525 an electronic or smart lock?
No, the 3525 is a fully mechanical brass mortise entry set, key on the outside and no electronics anywhere in it. If you want keypad or credential access on a mortise prep, that is a different product family: ZenSupply stocks the Alarm Lock Trilogy DL3500CR Grade 1 electronic mortise lock, the Schlage CO-100 standalone keypad mortise lock, and the Dormakaba E-Plex 2066 pushbutton keyless mortise lock. None of those are decorative brass entry sets, so it is a real tradeoff between appearance and access control.
