Schlage Commercial 80-036 SCHLAGE Everest & Everest 29 Uncombinated Core

It ships uncombinated: no keys, no pins, no springs, no slides. You pin it yourself to whatever bitting your Everest or Everest 29 system runs on, so budget a pin kit and cut keys alongside the core. Shops that key their own cylinders order cores this way on purpose. If you want a cylinder that arrives keyed with cut keys in the box, this is not that part.

Yes. The 80-036 is an uncombinated Everest and Everest 29 core, 7-pin, so a locksmith pins it to your existing bitting and it operates on the masters already in service. Nothing about it is preset, which is exactly what makes it usable in an established system instead of forcing a second keyway into the building. The 7-pin chamber count also gives a master key system more levels to work with than a 5-pin core.

They are two different interchangeable core formats. The Schlage 80-036 is an uncombinated Everest and Everest 29 core supplied in the SFIC core option. The Corbin Russwin 1080 is a Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, built for Schlage L9000 mortise locks and carrying an A01 Schlage L cam, so the core sits inside a mortise cylinder body that threads into the lock case and drives the lock through that cam. Confirm which core format the L9000 bodies on your doors were ordered with before you buy either one, since a small format core and a large format IC mortise cylinder are not interchangeable in the same prep.

No. Everest and Everest 29 are their own Schlage keyway families, and a Classic C key will not operate an Everest core. Running both on one system does not work, so pick a family and stay on it. If the openings you are adding have to stay on Schlage C and the prep is a mortise cylinder rather than an interchangeable core, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to Schlage C keyway.

Non-handed. One core covers either swing, so there is nothing to specify on the order and nothing to stock in duplicate. Handing only comes into play with the lock or exit device the core lives in, never with the core itself.

That works, with one step in between. Pull the compromised core with the control key, have the replacement pinned to a fresh change key that still runs under your existing master, and it goes straight back into the housing; every other opening keeps the keys it already has. Because the 80-036 arrives uncombinated, the pinning has to happen before it reaches the door, so this is a call to your locksmith rather than a same-hour swap. It is a commercial core and non-handed, so one part number covers any opening in the building.

The core comes in 626 satin chrome, which is the BHMA code for satin chrome, so the exposed face reads the same as 626 levers, mortise locks and exit trim already hanging on the doors. It is a standard commercial finish across brands. On a fleet of openings, keeping cores and trim on the same finish code is what keeps a rekey from looking like a patch job.

Staying with Everest or Everest 29 keeps you inside Schlage's keyway families. On the BEST side there are three: the 1C Series standard 5-pin core, the Peaks 1CB 150 Series interchangeable core, and the 1CDF, a drill resistant patented 7-pin brass core in the 150 Series. The real fork is pin count and whether the keyway is patented. A patented restricted keyway limits who can cut a duplicate; an open standard 5-pin core makes blanks and service easier to come by. Every cylinder in the system has to share one keyway family, which is why this gets decided once per facility and not door by door.

Narrow stile openings are usually cylinder driven at the deadlock rather than at a core housing. The Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 series and works down to a 1/2 inch minimum door thickness, which is the range narrow stile aluminum lives in. If the opening needs a pull that carries the cylinder, the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the Adams Rite 5017 wood door deadlock and deadlatch. The 80-036 is a non-handed core, so handing is not what rules it in or out here, the core housing prep is.

The Schlage 80-036 is an uncombinated Everest and Everest 29 core built on a 7-pin Primus classic cylinder, offered in the SFIC core option and in 626 satin chrome, and it comes without keys, pins, springs or slides. On the BEST side, the 1CDF is a drill resistant patented interchangeable core, 7-pin, in brass, from the 150 series, and the 1CB Peaks is an interchangeable core cylinder in the 1CB series. The dividing line is the key system rather than the housing: the 80-036 runs on Everest and Everest 29 keyways, while the BEST cores are cut to BEST key systems, so a building on one is running a separate master key chart from a building on the other.

The 80-036 is built on a 7-pin Primus classic cylinder in the Everest and Everest 29 family. The BEST 1C is a standard 5-pin cylinder core from the standard and premium cores line, so it is a shorter pin stack and a non-patented format. Within the BEST cores, the 1CDF sits at the other end: drill resistant, patented, 7-pin, brass, 150 series. All of them are cores rather than complete locks, and the 80-036 in particular arrives uncombinated, so it has to be pinned to your key system before it goes in the door.

The 80-036 is an uncombinated core and comes without keys, pins, springs or slides, so bench keying to your system is part of putting it in service. If you want a cylinder that shows up cut and ready to run, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway, supplied keyed different with two cut keys. Understand what you are changing when you go that way: the Falcon is a key-in-lever cylinder that belongs in a Falcon knob or lever lock, while the 80-036 is a core that drops into an interchangeable core housing and stays part of a keying system you control.

For a mortise body that is not prepped for an interchangeable core, the fit is set by cylinder length and cam. The Corbin Russwin 1000 is a Grade 1 series mortise cylinder at 1-1/2 inch with an A02 straight cam. The Corbin Russwin 1070 is a Grade 1 series 6-pin mortise housing at 1-1/4 inch with an A01 cloverleaf cam. The Detex MC65 is a 6-pin commercial grade mortise cylinder at 1-1/8 inch with a Schlage C keyway, which matters if the rest of the building runs Schlage classic keys rather than the Everest and Everest 29 keyways the 80-036 is built for.

Two groups get ordered by mistake. The BEST 12E is a dummy rim cylinder at 1-5/32 inch diameter in the 12E series, so it fills an opening and turns nothing. The Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, both designed for use with the Adams Rite MS1847 deadlock and deadlatch, which makes them door pulls that carry a cylinder rather than a replacement core. The 80-036 is an uncombinated core that goes into an interchangeable core housing and is keyed to an Everest or Everest 29 system.

They solve different problems. The Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Each of those is a rim cylinder matched by tailpiece and pin count to a specific lock it upgrades. The Schlage 80-036 is a commercial core, uncombinated, that goes into an interchangeable core housing so the core itself can be pulled and swapped with a control key.

For a lock that takes a key-in-knob or key-in-lever cylinder, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, and the 1579 is a knob and lever cylinder for Sargent locks. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway. Those thread or clip into the lock chassis itself. The Schlage 80-036 is an uncombinated Everest and Everest 29 core, so it needs a housing built to accept an interchangeable core, which is a different prep in the lock and a different way of rekeying later.
