Baldwin Reserve 8BR0204 Single Cylinder Deadbolt Cylinder Kwikset Smartkey with Housing and 2 Keys

The 8BR0204 deadbolt cylinder is a Kwikset SmartKey keyway, so it works within a SmartKey system. SmartKey lets you re-key the cylinder yourself with the tool and an existing working key, which is how you bring it onto the same key as the other SmartKey locks on the property. It's a 5 pin cylinder and ships with 2 keys.

It's the cylinder only, supplied with its housing and 2 keys. You're buying the keyed plug assembly that drops into a Baldwin Reserve single cylinder deadbolt, not the bolt, strike, or interior thumbturn. If the deadbolt body itself is failing, the cylinder won't fix it.

Baldwin lists the 8BR0204 as a residential product. For apartments, single family rentals, and light multi-family doors it's the right part. For a commercial opening under a Grade 1 or Grade 2 spec, or anywhere a master key system or high security keyway is required, look at commercial hardware instead. SmartKey is a residential re-key system, not an interchangeable core.

Yes, and that's the practical reason to use SmartKey across a fleet. Each 8BR0204 is a SmartKey 5 pin cylinder, so you can re-key any unit to a new key in seconds without pulling the lock or calling a locksmith, which is what you want on turnover. Order the finish that matches each door's Reserve trim: 004 Venetian Bronze, 150 Satin Nickel, or 190 Satin Black.

No - they are different parts of a door opening. The Baldwin Reserve 8BR0204 is a single cylinder deadbolt cylinder in a Kwikset SmartKey keyway, supplied with its housing and two keys; it is the keyed plug that operates a deadbolt. The Hager 3941 is a 3100 Series dead latch with a 2-3/8 inch backset and a 1 inch by 2-1/4 inch faceplate - a latch mechanism that mortises into the door edge and has no keyed cylinder. If the door needs a rekeyable deadbolt plug, the 8BR0204 is the part; if it needs the latching hardware bored into the edge, the Hager 3941 is a separate item and the two are ordered together, not one instead of the other.

Three: 004 Venetian Bronze, 150 Satin Nickel, and 190 Satin Black. Match the number to the rest of your Baldwin Reserve trim on that door, since the cylinder face is the visible part on the outside of the deadbolt. Baldwin uses the same finish codes across the Reserve line, so a 150 cylinder matches 150 levers and rosettes.

It's built for a single cylinder deadbolt, meaning keyed outside with a thumbturn inside. A double cylinder deadbolt is keyed on both faces and takes two cylinders, so this one part won't complete that opening.

Brass is the substrate. That matters on exterior doors, where a brass cylinder body holds up to weather better than pot metal, and it's why Baldwin can put a durable plated finish over it in bronze, nickel, or black.
