Which Kwikset Replacement Latch Fits Your Door?

Best for
Interior passage doors needing a basic latch

The Kwikset 6-Way Adjustable Plain Latch (part 81847-001) is a genuine Kwikset replacement in an unfinished face. A plain latch, as the name is generally used in door hardware, is a spring latch without the extra deadlatch plunger, which makes it the typical choice for interior passage doors such as a hallway, closet or game room where you just need the door to stay shut.

The listing is sparse. The title says 6-way adjustable, but the listing does not specify which backsets or mortise shapes it supports. It also lists the item weight as 0.16 ounces while the features list a package weight of 0.16 pounds, so one of those figures is wrong. Check the backset on your door before ordering.

It suits a quick fix on a sticky or broken interior latch. If the door faces outside or you want some resistance against someone slipping the latch, look at the entry or dead latch options below.

Best for
Older doors with a 5-inch backset

The Kwikset Security 83014-015 is a narrow-purpose part: it only fits doors with a 5-inch backset hole and a standard rectangular face, and it fits deadbolt mechanisms with square-corner mortising only. Five-inch backsets show up mostly in older homes, so if your deadbolt sits unusually far from the door edge, this is the part to measure against.

It comes in polished brass to match Kwikset polished brass knobs and levers, and the listing says complete installation instructions are included. The listing uses both “deadlatch” and “deadbolt latch” to describe it, and the description says it replaces the latch on a Kwikset deadbolt. Warranty terms also conflict: the features and description state 10-year mechanical and 5-year finish warranties, while the specifications say a 1-year mechanical warranty.

Choose it only if you have measured a 5-inch backset. For the far more common 2-3/8 or 2-3/4 inch backsets, the 1825 dead latch or 83186 drive-in latch is the right direction.

• Fits 5-inch backset with rectangular face
• Square-corner mortise only
• Polished brass finish

Best for
Replacing a worn deadbolt latch

The Kwikset 1825-18 6-Way Adjustable Dead Latch (model 81825-001) is the most flexible replacement here. It fits square-corner, round-corner or circular drive-in applications and adjusts for 2-3/8 or 2-3/4 inch backsets, which covers most modern doors. The listing calls it a replacement deadbolt latch with a full 1-inch throw and says it meets ANSI/BHMA Grade 1 security specifications.

A few listing fields do not line up. The included components field says “Camera,” which is clearly an error for a latch. The features promise a lifetime finish and mechanical warranty, while the description mentions 10-year mechanical and 5-year finish warranties. The finish is polished brass.

This is the pick for someone whose existing Kwikset deadbolt still turns but whose latch is worn or damaged, and who wants one part that adapts to whatever mortise is already cut. If your door has a 5-inch backset, it will not fit; use the 83014 instead.

• 6-way adjustable for mortise shape and backset
• 2-3/8 or 2-3/4 inch backset
• 1-inch throw
• Polished brass finish

Best for
Contractors matching antique brass hardware

The Kwikset 81826-001 Antique Brass Adjustable Entry latch is listed with almost no detail beyond its title: an adjustable entry door latch in antique brass. Entry latches generally pair with keyed entry knobs and levers and include a deadlatch plunger to resist slipping, but the listing itself does not specify backsets, mortise types or warranty.

The specifications list an item package quantity of 10 and a weight of 3 pounds, which suggests a multi-pack, yet the title does not say so. Confirm the quantity on the product page before ordering. If it is a ten-pack, it will appeal more to landlords or contractors refitting several doors than to someone fixing one.

It suits readers who need the antique brass finish specifically to match existing hardware. If you need documented specs, the 1825 dead latch listing is far more complete. For a whole replacement set instead of a single part, see our guide to the Kwikset entry door lock set.

Upgrading a gaming room door to a deadbolt

The Kwikset 816 Key Control Deadbolt Lock is not a latch replacement but a complete single-cylinder deadbolt in round satin nickel. It locks from outside with a key and from inside with a turn piece, and the listing recommends it for exterior doors or for securing interior rooms with a key. That makes it the upgrade for a gaming room or home office holding expensive gear.

It uses SmartKey Security, which the listing says protects against advanced break-in techniques and lets you rekey the lock yourself in seconds. Security, durability and finish are Grade 2 BHMA certified. The box includes the exterior keyed deadbolt, interior turn piece, adjustable latch, two keys, screws, strike plate, SmartKey tool, installation hardware and guide. It fits doors 1-3/8 to 1-3/4 inches thick with an adjustable latch backset from 2-3/8 to 2-3/4 inches, and the hardware is Microban treated. The listing states a lifetime mechanical and finish warranty.

Pick it when you want a key on the door, not just a latch that clicks shut. It requires a deadbolt bore; if your door only has a knob hole, drilling is needed. If you would rather skip keys, our look at keypad door locks covers code-entry options.

Best for
Deadbolt doors without an edge mortise

The Kwikset Corporation 83186-001 Adjustable Drive-in Deadbolt replacement latch is built for doors without an edge mortise. A drive-in latch has a round collar that presses into the bored hole, so there is no chiseled pocket for a faceplate. It adjusts for 2-3/8 or 2-3/4 inch backsets, and the listing says no special preparation is required.

The listing advises measuring backset, cross bore and door thickness before buying. It does not specify throw length, finish or warranty, so the 1825 remains the better-documented choice if your door does have a mortise.

This fits a deadbolt door where someone originally installed a drive-in latch, common on budget pre-hung doors, and you need a matching replacement.
