Kwikset 83014 5" Replacement Square Corner Deadlatch, 1" x 2-1/4" Face

Treat it as a Kwikset service part. The 83014 is built for Kwikset locksets, and latch tailpiece and cam engagement is brand specific even when the face dimensions look identical. For a Dexter C1000 lockset, the Dexter Grade 1 deadlatch for the C1000 Series is the matching part. For Schlage S200 series, the Schlage 16-480 deadlatch is the one, adjustable to 2-3/8 or 2-3/4 inch backset with a 1 x 2-1/4 inch square corner face.

No. The 83014 has a square corner face, so it drops into a door mortised with square corners. A door prepped with a radius corner faceplate leaves a gap at each corner unless you re-chisel the mortise square. For a round corner prep, look at a radius corner deadlatch instead, such as the Schlage 12-289 with its 1/4 inch round corner and 1 x 2-1/4 inch face.

The 83014 is a 5 inch latch, which is the long backset version, so it suits the 2-3/4 inch backset prep found on most commercial and exterior doors. If your door is bored at 2-3/8 inches, the shorter Kwikset latch is the one you want. Measure from the door edge to the center of the knob bore before ordering, since that dimension is what decides it.

In most cases yes, provided the strike is set for the same 1 x 2-1/4 inch faceplate geometry and the door edge to strike alignment has not changed. The point to check is the deadlatch plunger: it has to land on the flat face of the strike plate, not drop into the strike opening. If the plunger falls into the hole, the latch is not deadlocked and the door can be slipped. Shift the strike or use a strike with a wider lip if that happens.

The nearest match is the Schlage S200 Series 16-480 deadlatch, which shares the 1 inch by 2-1/4 inch square corner faceplate dimension the Kwikset 83014 uses. The difference is backset: the 83014 is a 5 inch square corner deadlatch, while the 16-480 is adjustable to either a 2-3/8 inch or 2-3/4 inch backset, so one 16-480 covers both common bore centers. Both are deadlatches, meaning the latchbolt carries a deadlocking plunger rather than being a plain spring latch. Confirm the existing faceplate mortise in the door edge is a square corner cutout before swapping either way, since a round corner prep will not take a square corner face without filing.

The Kwikset 83014 is a square corner deadlatch with a 1 inch by 2-1/4 inch face, so it will not drop into a radius corner prep without rework. For a round corner opening, the Schlage Commercial 12-289 uses a 1 inch by 2-1/4 inch face with a 1/4 inch round corner and an adjustable 2-3/8 inch or 2-3/4 inch backset, matching the same face width and height. Note that the 12-289 is a B500 Series deadbolt latch rather than a deadlatch, so it suits a deadbolt bore, not a keyed knob or lever bore. Measure the corner radius on the old faceplate before ordering; a 1/4 inch radius prep and a square prep are not interchangeable.

The Schlage 12-630 is the one most often pulled by mistake. It is a square corner part with a 2-1/4 inch face height, so it photographs like the Kwikset 83014, but it is a deadbolt latch for the Schlage B600, B700 and B800 Series with a 1-1/8 inch face width and a fixed 2-3/8 inch backset. The 83014 is a deadlatch, the spring-loaded latchbolt with a deadlocking plunger that works with a keyed knob or lever, not a thrown bolt. A deadbolt latch has no anti-friction plunger and will not retract from a knob or lever. Match the function first, then the face dimensions.

A deadlatch has a small auxiliary plunger sitting alongside the main latchbolt. When the door closes, the plunger rests on the strike plate and blocks the latchbolt from being pushed back, which defeats loiding with a credit card or shim. A plain spring latch has no plunger and can be slipped. The Kwikset 83014 is a deadlatch, which is why it is the correct part for an exterior or tenant entry door. If the opening is an interior passage or privacy door where security is not the point, a regular latch like the Deltana G1RLP275 covers it.

The Kwikset 83014 is a fixed 5 inch latch, not adjustable. If you are stocking a truck or a maintenance shop and want one part that covers both preps, an adjustable-backset latch is the better buy: the Schlage 16-228 for S200 and CS210 series adjusts between 2-3/8 and 2-3/4 inch with a 1-1/8 x 2-1/4 inch square corner face, and the Schlage 16-480 does the same with a 1 x 2-1/4 inch face.

No handing to specify on the 83014. The latchbolt is reversible in the field: pull the latch out, rotate the bolt so the bevel faces the direction the door closes, and reinstall. Order the same part for a left hand or right hand opening.

If the knob or lever still turns freely, the cylinder keys fine, and the only fault is the latch sticking, not retracting, or the deadlocking plunger seizing, the 83014 latch alone fixes it and you keep the existing keying. Replace the full lockset when the cylinder is worn, the keying needs to change, or the chassis is loose in the door. For a keyless swap on the same prep, a Lockey M230 deadlocking spring latch lock covers 1-1/8 to 2 inch doors with an adjustable backset.

For a fire rated opening, the Accentra YSSL10 security sidelite auxiliary latch carries a fire rating and is built for a 1-3/4 inch door thickness, with an ADA compliant thumbturn on the inside. The Kwikset 83014 is a commercial replacement deadlatch and should be specified against the lockset and the label already on the door. On a labeled opening the assembly is what carries the rating, so confirm the latch you order is listed for the door and frame combination in the field before it goes in.

Use the Dexter deadlatch built for the C1000 Series, which is a Grade 2 deadlatch matched to that chassis. The Kwikset 83014 is a Kwikset replacement deadlatch and is sized to Kwikset chassis geometry, so it is not the part to order against a C1000 lock body. Replacement latches are keyed to their own lock family at the tailpiece and retractor interface even when the faceplate looks similar, so buy the latch for the brand of lock already in the door.

Deltana publishes Grade 1 regular latches in four configurations, split by function and backset: the G1RLE238 and G1RLE275 are entry function at 2-3/8 inch and 2-3/4 inch backset, and the G1RLP238 and G1RLP275 are passage and privacy function at the same two backsets. Order by measuring from the door edge to the center of the bore, then match the function of the trim going on the door. One point of difference to note: the Deltana parts are regular latches, while the Kwikset 83014 is a deadlatch, so if the opening needs a deadlocking plunger against latch shimming, that is a functional change and not just a grade change.

If the goal is to get off keys entirely rather than repair the existing lock, the Lockey M230 is a mechanical keyless digital combination lock with a deadlocking spring latch and an adjustable backset, and it fits doors from 1-1/8 inch to 2 inch thick. That replaces the whole lock rather than just the latch. The Kwikset 83014 is the path when the lock body itself is sound and only the 5 inch square corner deadlatch needs changing out. Both approaches use a deadlocking latch, so the security behavior at the strike is comparable; the decision is whether you are servicing an existing lockset or changing how the door is operated.

Two finishes are offered on the 83014: polished brass and satin chrome. Satin chrome is the one to pick against brushed nickel or satin chrome levers, polished brass against bright brass. Only the faceplate is visible once the latch is installed, so on a fleet of doors matching that plate to the existing knob or lever trim is all that matters visually.

The latch face is the only visible part once the door is closed on the frame side, and it shows on the door edge. The Kwikset 83014 comes in polished brass and satin chrome, so on a fleet of doors where edges are visible you can spec the latch face to sit with the rest of the trim. If you cross to the Schlage S200 Series 16-480 for its adjustable 2-3/8 inch or 2-3/4 inch backset, the face is the same 1 inch by 2-1/4 inch square corner footprint but you are matching a different manufacturer's finish naming, so verify the edge finish against a sample before standardizing a building on it.
