Kwikset KWI-971PSKRDT Single Cylinder Interior Pismo Knob Trim with Round Rose

No handing to specify. The Pismo interior trim is universal handing and fully reversible, so the same part goes on a left hand or right hand door. For a property manager doing a run of units, that means one part number covers every opening regardless of swing, and nobody has to count doors before ordering.

Kwikset handlesets only. The Pismo trim is built for installation with Kwikset handlesets, and the interior and exterior halves share a spindle and mounting pattern that is specific to that system. Pairing it with another manufacturer's exterior half is not something Kwikset supports. If the exterior on the door is not Kwikset, replace both halves.

No. Handleset trim like the Pismo is made for a bored wood or steel residential entry door, and a narrow stile aluminum door does not have the stile width or prep for it. For that opening look at the Lockey 2950 narrow stile hookbolt pushbutton lock, which runs a 1-1/8 inch backset and fits doors 1-1/8 to 2 inches thick, or the Lockey 2500 Series with an adjustable backset over the same 1-1/8 to 2 inch thickness range.

They solve different problems at the door. The Pismo interior knob trim is the inside half of a Kwikset handleset - a knob on a round rose with an interior turn piece that throws the lock, and the matching Kwikset exterior pack is bought separately. The Codelocks CL250 is a tubular latch with key override from the CL200 series, so entry is granted by the code entered on the lock rather than by an interior turn piece. If the opening needs keypad entry for people who do not carry a key, the CL250 is the direction; if it needs a keyed residential entrance with a thumbturn inside, the Pismo trim is.

The BEST 8T Series closet function non-keyed tubular deadbolt gives you a blank plate on one side and a thumbturn on the other, with no knob or lever at all, and it is built for a 1-3/4 inch door. The Kwikset Pismo interior trim pairs the turn piece with a knob on a round rose and is meant to install with a Kwikset handleset. Pick the BEST 8T when the door only needs to be secured from the inside and there is nothing to grip on the outside; pick the Pismo trim when the inside of a handleset door needs both a knob and the turn piece.

Six: Venetian Bronze, Satin Nickel, Bright Chrome, Satin Chrome, Satin Brass and Matte Black. Order the interior trim in the same finish code as the Kwikset exterior pack it is pairing with, since the two ship as separate parts and a mismatch shows up on the same door leaf. Venetian Bronze and Matte Black are the two that read darkest against a painted door.

A turn piece on the inside face does the locking. Turn it to throw the lock, turn it back to release. The knob itself is the grip, not the locking control, and the key side lives on the exterior pack. It is a single cylinder setup, so there is no key required from the interior, which is what you want on a bedroom-side or unit-entry door where an occupant needs to get out fast.

No. Single cylinder means the key works the outside only, with a thumbturn inside. If a unit has glass sidelights next to the door and you want to defeat a break-and-reach, you want a double cylinder arrangement instead, which takes a key on both faces. The Pismo interior trim cannot be converted to that, since the interior control is a turn piece by design.

Nothing in the Pismo line does codes, it is a keyed mechanical handleset trim. For pushbutton or code entry, look at the Codelocks CL250 tubular latch with key override for a light-duty code-plus-key opening, or the Codelocks CL510/CL515 and CL610/CL615 back-to-back tubular latchbolt units, both rated heavy duty, where the door sees real traffic from both sides. Those replace the whole lock, not just an interior trim.

The BEST 8T Series closet function tubular deadbolt is the straightforward one: blank plate on one face, thumbturn on the other, no keyway at all, for 1-3/4 inch doors. The Kwikset Pismo interior trim is not that part, it is a keyed entrance function and it only works as half of a Kwikset handleset with the exterior pack bought separately.

Both are tubular latchbolt back-to-back locks rated heavy duty - the CL510 and CL515 are the CL500 series, the CL610 and CL615 are the CL600 series. Back-to-back means the opening is coded on both faces rather than carrying a knob and turn piece. That is a different user experience from the Kwikset Pismo interior trim, which is a knob on a round rose with an interior turn piece and comes with 2 keys. Choose back-to-back when you do not want to issue keys to the people using the door.

No. The Kwikset Pismo interior knob trim is universally handed, fits right and left hand doors, and installs in minutes with a screwdriver, but it is trim that mounts to a Kwikset handleset prep rather than a lock with its own adjustable bore. The Lockey 2500 Series mechanical keypad hook bolt lock has an adjustable backset and fits doors 1-1/8 to 2 inches thick, which is the option when the existing hole pattern will not line up to a fixed backset.

A screwdriver. The interior trim mounts to the exterior pack already in the door, so there is no boring, no chisel work and no template as long as the existing prep was cut for a Kwikset handleset. That makes it a practical in-unit swap for maintenance staff rather than a job that needs a door prep kit.

Yes, Microban antimicrobial protection is built into the Pismo trim, and Kwikset states it keeps the hardware 99.9% cleaner than unprotected surfaces. That is a surface-cleanliness claim on the hardware, not a health or infection-control claim, so it is worth noting on a shared-corridor or amenity door but it does not substitute for whatever cleaning protocol a facility already runs.
