Schlage B610-203 626 – Frequently Asked Questions

1) Will the Schlage B610-203 cylinder housing fit a 2-inch thick door?
Yes. The B610-203 housing covers doors from 1-3/8 inches up to 2-1/4 inches thick, so a 2 inch door is inside the range. That span also covers standard 1-3/4 inch commercial doors and older 1-3/8 inch interior doors.
2) Can I replace just the cylinder housing instead of the whole deadbolt?
That is exactly what the B610-203 is for. It is a genuine Schlage replacement housing for B500 Series deadbolts, so a damaged or worn housing can be swapped in the field and the rest of the lock body, core and strike stay in place. Useful when a housing gets wrenched or finished-scarred on a high-traffic opening.
3) Does the B610-203 come with a cylinder or core?
No core is part of it. The B610-203 is the housing only, made to accept a Full Size Interchangeable Core, so you reuse your existing FSIC core or order one keyed into your system separately.
4) If the deadbolt uses a small format interchangeable core instead of a full size core, what housing should be used in place of the Schlage B610-203?
The B610-203 is built for Schlage B500 Series exterior single Full Size Interchangeable Core (FSIC) deadbolts, so it is the wrong housing for an SFIC cylinder. For a small format interchangeable core, the Kaba Ilco R2800 Series is a small format IC core convertible housing. Confirm the core format stamped on the existing cylinder before ordering, since FSIC and SFIC cores are not interchangeable in the same housing.
5) What finishes is the Schlage B610-203 housing available in, and can I match the other deadbolts in my building?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel and 626 satin chrome. Those are standard BHMA finish numbers, so match the number stamped on or specified for the existing B500 deadbolts rather than eyeballing the color. 626 satin chrome and 613 oil rubbed bronze are the two most common on commercial openings.
6) I want to convert a lock to interchangeable core rather than replace a Schlage FSIC housing. What are my options?
The B610-203 is not a conversion part, it is the FSIC housing for a B500 deadbolt that already runs interchangeable core. If the goal is converting existing hardware to IC core, look at a convertible housing instead: the Kaba Ilco S26506 is a mortise large format IC core convertible housing in the Schlage size, and the Kaba Ilco R2800 Series is a small format IC core convertible housing. Large format is the size Schlage FSIC uses, so the S26506 is the closer match if your keying system is already Schlage large format.
7) Does the B610-203 support master keying?
Yes, by way of the core. Because the housing takes a Full Size Interchangeable Core, the keying lives in the removable core, so the opening can be pulled into a master key system or rekeyed with a control key without touching the housing.
8) Is the B610-203 suitable for school and hospital doors, or is it a residential part?
It is a commercial part, built to Schlage's commercial-grade specifications for the B500 platform. Typical use is office buildings, schools, healthcare, government buildings, multi-tenant residential, warehouses and retail.
