Kwikset Deadbolt Installation Nationwide

Kwikset Deadbolt Installation: The New York Owner’s Guide

We install Kwikset deadbolts same-day across New York for a flat installed price of $195-$325, depending on whether your door needs fresh drilling or fits a standard 2-1/8″ bore. That quote is the full price - hardware, labor, and testing - and we stock the full Kwikset lineup on our trucks: 660 Series, 980/985 SmartKey, and 994 contemporary lines. Most jobs in Manhattan, Brooklyn, and Queens take under 45 minutes from the time we park.

Call (833) 317-5852

Homeowners usually call us when the thumb turn spins without engaging the bolt, when the key catches at 10 o’clock and won’t budge, or when the bolt sticks halfway in winter. In pre-war buildings on the Upper West Side, we see a lot of misaligned strikes from settling frames. In newer construction in Long Island City, the issue is often a builder-grade Kwikset that was never lubricated and seizes after five years.

Which Kwikset Models This Applies To

Kwikset has made deadbolts since 1946, and the mounting specs have stayed remarkably consistent - but the internal mechanisms have changed twice. If your lock was made before 2008, it likely uses the traditional pin-tumbler system. From 2008 forward, most residential lines carry SmartKey re-key technology, which uses a sidebar instead of bottom pins. The two are not interchangeable in the cylinder.

To identify what you have: look for “SmartKey” stamped on the keyway face, or check the key head for a small “+” symbol. The 660 Series is the standard single-cylinder deadbolt with a thumb turn inside. The 980 Series adds SmartKey and a reinforced strike plate. The 985 double-cylinder uses a key on both sides - required by code for doors with glass within 40 inches of the lock in many New York municipalities.

We stock both OEM Kwikset hardware and quality Grade 2 aftermarket equivalents from Arrow and Falcon. For rental properties in Astoria and Washington Heights, we often recommend the aftermarket option - same ANSI Grade 2 rating, same 1″ throw, roughly 30% less cost. For owner-occupied homes in Park Slope or Forest Hills, most customers want the Kwikset box with the lifetime finish warranty. We carry both on the truck and will show you the difference before we open anything.

Signs Your Kwikset Deadbolt Installation Is Failing

• The thumb turn spins freely but the bolt doesn’t move. The tailpiece connecting the thumb turn to the bolt mechanism has sheared or slipped its clip. This is the most common failure we see in Kwikset 660s after 8-12 years of use. The pot metal tailpiece fatigues at the bend point.
• The key works in warm weather but sticks when temperatures drop below 30°F. The factory lubricant has gummed with dust, or the cylinder wafers in a SmartKey lock are dragging. New York’s freeze-thaw cycles push moisture into keyways, especially on south-facing doors where snow melts and refreezes daily.
• The bolt extends only halfway or requires shoulder pressure to seat. The door frame has settled, or the strike plate was never properly mortised. In brownstones from Bed-Stuy to Harlem, we’ve measured frame shifts of 1/4″ or more as buildings compress over decades. The lock is fine - the geometry is wrong.
• The deadbolt is loose in the door and wobbles when you turn it. The mounting screws have stripped the wood, or the faceplate screws have backed out. This happens often in hollow-core doors where the initial installation used the short screws that come in the retail box instead of the 3″ security screws we install standard.
• You hear a click but the bolt doesn’t retract fully. The bolt itself is bent, or the internal cam is worn. This is more common in double-cylinder 985 models where tenants force the key against a sticky bolt rather than addressing the alignment.

Replacement Cost & What’s Included

Our flat installed pricing for Kwikset deadbolt installation in New York:

• Standard replacement (existing bore, no drilling): $195-$245
• Fresh installation or old bore repair: $265-$325
• SmartKey re-key to match existing house key: $35 (included free with 980/985 install)
• Upgraded 3″ strike plate with 3″ screws: no extra charge

What drives the range: door thickness over 1-3/4″ requires longer tailpieces; metal doors need specialized bits and slower drilling; pre-war plaster-and-lath frames often need strike box reinforcement. We tell you exactly where you land before we drive. The 90-Day Done Right Promise covers everything - if the bolt sticks or the finish flakes, we come back. No paperwork to file, no arguing.

Seniors and veterans receive 5% off any installation. If your previous locksmith gave you a written estimate, we’ll provide a free second opinion.

DIY or Call Us?

There is nothing dangerous about installing a deadbolt - no springs under tension, no electrical, no gas. But there is plenty that goes wrong.

What you can safely check: remove the two mounting screws and confirm the tailpiece is seated in the bolt cam. If it slipped out, re-engaging it takes thirty seconds. You can also test whether the bolt moves smoothly with the thumb turn removed - if yes, the lock body is likely fine and the issue is alignment.

Where DIY fails: drilling a new bore without a door jig leaves scars that can’t be hidden. SmartKey cylinders require a working key to re-key - lose it, and you’re buying a new cylinder. And in New York’s older housing stock, what looks like a simple swap often reveals a door that has been drilled three times by previous owners, with splintered wood that won’t hold screws. We carry hardwood dowels and epoxy on the truck for exactly this. Flat price before the truck rolls - that is the only way we know how to do it.
