Sargent 77-3450 3 – Frequently Asked Questions

1) What exactly comes with the Sargent 77-3450 escutcheon, and do I have to buy a cylinder separately?
The Sargent 77-3450 is an outside escutcheon supplied with an LW1/KW1 cylinder, so the trim plate and the cylinder come together as one assembly. It covers the exterior face of the door only, so if you also need the inside trim you are ordering that as a separate part.
2) Can the Sargent 77-3450 cylinder be keyed into our existing building master key system?
The cylinder shipped with the 77-3450 is cut for the LW1/KW1 keyway. If your Sargent openings are already on LW1/KW1, it belongs to the same keying family and your locksmith can key it to your existing system. If your building runs a different Sargent keyway, this one will not accept those keys.
3) Do I have to replace the whole lock, or can I just swap the outside trim?
For a Sargent mechanical lock, the 77-3450 lets you replace just the outside escutcheon and its cylinder. The lock body and interior trim stay in the door, which keeps a worn or vandalized exterior plate from turning into a full hardware changeout.
4) Is the Schlage 47260707 CO Series exterior escutcheon a substitute for the Sargent 77-3450?
No. The Sargent 77-3450 is a mechanical outside escutcheon supplied with an LW1/KW1 cylinder for keyed entry on Sargent commercial mechanical lock systems. The Schlage Electronics 47260707 is a CO Series exterior escutcheon for cylindrical and mortise locks built around a keypad, so it serves electronic access control rather than a key cylinder. If the opening is being kept mechanical and key-operated, the 77-3450 is the part that matches; the CO Series escutcheon belongs on a CO100 keypad lock.
5) Will the Sargent 77-3450 match the finishes on the rest of my door hardware?
Eleven finishes are offered: 03 Bright Brass clear coated, 04 Satin Brass clear coated, 09 Bright Bronze clear coated, 10 Satin Bronze clear coated, 10B Dark Oxidized Satin Bronze oil rubbed, 10BL Dark Oxidized Satin Bronze clear coated, 15 Satin Nickel plated clear coated, 20D Dark Statuary Bronze lacquered, 26 Bright Chromium over nickel, 32 Bright Stainless Steel, and 32D Satin Stainless Steel. Match the BHMA number stamped on your existing Sargent trim and you will get a consistent look across the fleet.
6) I need to order a replacement outside trim for a Sargent lock. What do I have to specify?
Two things settle the order: the model, 77-3450, and the finish code. The keyway is fixed at LW1/KW1 on this assembly, so that is not a choice you make. Give your locksmith the existing key bitting if you want it keyed alike to the other doors.
7) I need an escutcheon for exit device trim, not a lock. Is the Sargent 77-3450 right?
The Sargent 77-3450 is an outside escutcheon with an LW1/KW1 cylinder intended for Sargent mechanical lock systems, not for exit device trim. For an exit trim application the Schlage Electronics 47260708 is a CO Series exterior escutcheon made specifically for exit trim on CO-100 keypad hardware, in an Aged Bronze finish. Choose by the hardware the escutcheon mounts to: mechanical lock versus exit device trim.
8) What is the difference between the Sargent 77-3450 escutcheon and MS Sedco ESC escutcheon plates?
They cover different devices. The Sargent 77-3450 is a commercial outside escutcheon that carries an LW1/KW1 cylinder on the exterior face of a door using Sargent mechanical lock hardware. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, so it trims a push switch rather than a key cylinder. Ordering the Sedco plate for a keyed opening will leave you with no cylinder mounting.
9) Is the Sargent 77-3450 escutcheon suitable for high-traffic commercial doors, or is it a residential part?
It is a commercial-grade part, catalogued for commercial mechanical lock service rather than residential use. Typical placements are office buildings, schools, healthcare, retail, government facilities, multi-tenant residential, and warehouse openings.
10) Which finish holds up best outdoors or in a coastal building?
Among the eleven choices, the two stainless options, 32 Bright Stainless Steel and 32D Satin Stainless Steel, are the ones to specify for exposed or humid openings. Oil rubbed 10B is a living finish that will change tone with handling, while the clear coated brass and bronze finishes such as 03 and 09 are better kept to interior openings.
