One door, no wiring, no monthly login

A property manager doesn't need a networked access system for a single storeroom door. What they need is a lock that takes a code, holds it, and doesn't need an electrician or an IT ticket to install. That's the job the Schlage CO-100 is built for.

It's a battery-powered, offline cylindrical keypad lock. No wiring, no panel, no network connection of any kind. You mount it, you set codes at the lock itself, and it works. There's no card reader, no fob, no software login, just a keypad. If you're picturing something that reports back to a dashboard or lets you audit who came in at 2am, this isn't that lock. It's standalone by design, and that's the whole appeal for a single door.

Why this fits a storeroom or classroom door specifically

The CO-100 ships in Classroom/Storeroom function. That's not a marketing term, it's a specific behavior. The outside lever stays locked at all times. A valid code at the keypad retracts the latch and lets someone in; the door relocks itself as soon as it closes. From the inside, the lever always turns and always lets you out, full stop, no code needed. That's the function you want on a storeroom, a supply closet, or a single classroom where you're controlling entry but you never want to think about egress in an emergency.

Codes get added and deleted right at the lock. No app, no cloud account, no site license. If you've got one door and you don't want to manage software for it, that's a feature, not a limitation.

Think about what that means for a school supply closet mid-semester. A teacher leaves in October, and the old code needs to die that afternoon, not whenever the district's IT contractor can schedule a site visit. Whoever holds the master programming code punches it in, deletes the old user code, adds a new one, and walks away. Five minutes, no truck roll, no ticket number.

Hardware you should know about before you order

• Rated Grade 1 under ANSI/BHMA A156.25, the commercial-duty tier, not a residential-grade lock with a keypad bolted on.
• UL 294 listed for access control, which matters if your building's insurance or code inspector asks.
• Runs on field-replaceable AA batteries, the kind your maintenance guy already has in a drawer, not a proprietary battery pack you have to special-order.
• Fits standard 1-3/4" commercial doors.
• Satin Chrome finish, Sparta lever.

I'll say this plainly: if you need this door to talk to a network, trigger a lockdown from the front office, or show up in an audit log, the CO-100 is the wrong lock. It has none of that capability, on purpose. If a lockdown-capable networked opening is actually what you're after, look at our piece on the Schlage LE-Series instead, different lock, different job. And if you'd rather not deal with batteries at all, even AAs, we've also covered the mechanical Simplex 1000 pushbutton lock, which runs on nothing but a spring and a code wheel.

FSIC or SFIC, match what's already on the building

This is the one decision you actually have to make, and it has nothing to do with the electronics. The CO-100 comes prepped for one of two core formats, and Lock Depot stocks both:

• Prepped for a Schlage Everest full-size interchangeable core (FSIC), SKU CO-100-CY-70-KP-SPA-RD-626
• Prepped for a small-format interchangeable core (SFIC), SKU CO-100-CY-70-KP-SPA-GD-29R-626

Everything else about the two is identical: same body, same lever, same battery setup, same Classroom/Storeroom function, same finish. The only thing that changes is which core format the lockset accepts. Don't pick this based on preference. Walk the building, find out what core format is already in the other cylinders, and order the matching one. Mixing formats on one property just means you're carrying two sets of control keys and two sets of pinning kits for no reason. If your building has never had interchangeable cores at all, that's a conversation to have with whoever's doing your keying before you order either one, call us and we'll walk through it.

How you actually buy one

Both configurations are in stock. But neither one has a listed web price, this product is sold by phone only. That's not a glitch in the site. Keypad locks like this get configured to the job, core format, sometimes keying details beyond that, so we quote it live rather than post a number that might not match what you actually need. Call (877) 365-5625 or email sales@lock-depot.com, tell us FSIC or SFIC, and we'll confirm the configuration and get you a number and a ship date.

If you're not sure which core format your building uses, that's a normal question to bring to the call, we'd rather ask than have you guess and end up with a lockset that doesn't take your existing cores.

Common questions

Does the CO-100 connect to a network or access control software?

No. It's a standalone, offline lock. Codes are programmed directly at the keypad, and there's no wiring, panel, or software involved. If you need networked lockdown or audit-trail reporting, this isn't the right product, ask us about Schlage's wired and wireless lines instead.

What happens if the battery dies?

The lock runs on standard AA batteries that your maintenance staff can swap out in the field, the same as changing batteries in any household device. No proprietary battery pack to order and wait on.

Can someone get locked in from the inside?

No. Classroom/Storeroom function means the inside lever always turns and always lets you out, regardless of whether the outside is locked or a code has been entered. Free egress is built into the function, not optional.

How do I know whether I need FSIC or SFIC?

Check what core format is already installed in the rest of your building's interchangeable-core cylinders and order to match. We haven't given ourselves permission to guess on this one, if you're unsure, call (877) 365-5625 and we'll help you confirm it before you order.
