Sargent SGT-10-C8-1 4 – Frequently Asked Questions

1) Will a Sargent Signature cylinder work in my existing Sargent master key system?
Yes. The Signature 8 Line bored lock cylinder blends into most existing Sargent key systems, so a single master key can operate both Signature and non-Signature cylinders. It's available in the majority of Sargent keyways, which is what makes it a practical way to raise key control on selected doors without rebuilding the whole system.
2) Can someone with a regular Sargent key open a Signature cylinder?
No. Signature keys operate both Signature and non-Signature cylinders, but a non-Signature key will not turn a Signature cylinder. The Signature cylinder is a 6-pin design with 2 added blocking bars and shear lines working with factory-loaded side pins, and only a dimpled key with the matching side pin depths and locations will release them. That one-way relationship is how you create a higher security tier on specific doors while keeping the building's existing keys working everywhere else.
3) What stops tenants from getting Signature keys copied at a hardware store?
The Signature key is an exclusive end-user pattern with a dimpled blade, and the cylinder's side pins are factory loaded to depths and locations that only that pattern matches. A hardware store blank won't cut a working key, which is the point of the protected key control on these cylinders for multi-tenant, healthcare, and school properties where keys wander.
4) Do I have to specify keying when I order these Sargent Signature cylinders?
Yes, keying is a required selection. You choose standard keying, KD (keyed different, every cylinder on its own key), or KA (keyed alike, a group of cylinders all operating from one key). For a building where a super or maintenance tech covers a run of doors, KA on that group plus your existing Sargent master is the usual setup.
5) Is the 10-C8-1 a replacement cylinder for a bored lock, or a whole lockset?
It's the cylinder only, a replacement part for Sargent 8 Line bored (cylindrical) locks. You reuse the existing lockset and chassis and swap the cylinder, which is why upgrading a facility to protected key control takes minimal effort. If the lock body itself is worn or you need a different function, you'll need a complete bored lock instead.
6) Can I upgrade only some doors to Signature and leave the rest alone?
That's exactly what the system is built for. Put Signature cylinders on the doors that need tighter control, exterior entries, IT rooms, pharmacy, records, and leave standard Sargent cylinders elsewhere. The master key still opens both, and the Signature-keyed doors simply can't be opened by the lower-level keys. No need to rekey the whole building at once.
7) What finishes does the Sargent 10-C8-1 Signature cylinder come in?
Two: 04 satin brass with clear coat, and 15 satin nickel plated with clear coat. Pick the one that matches the lock trim already on the door, since the cylinder face is the visible part once it's installed.
8) Is the Sargent Signature cylinder suitable for residential doors?
It's built for commercial openings, offices, schools, hospitals, retail, warehouses, government buildings, and multi-tenant residential. The Signature key system it belongs to is a facility-level key control program, so a single-family house gets little out of it. Apartment and condo portfolios, where key control across many units is the real problem, are a different story.
