In-Depth Reviews

1. Stanley Black & Decker DOOR LOCK INSTALLATION KIT — Best Budget Pick

Stanley Black & Decker's door lock installation kit is a no-frills, proven performer that's been a jobsite staple for decades. The Hanson bi-metal design handles both wood and hollow-core doors without complaints, and the jig provides reliable alignment for standard backsets. For homeowners who need to replace a single lockset and don't plan to make a career out of it, this kit delivers exactly what it promises at a price that doesn't require a second thought.

The bi-metal hole saw construction resists heat buildup during cutting, which extends blade life significantly compared to standard carbon steel alternatives. The kit is compact and lightweight, making it easy to handle solo. It won't win awards for innovation, but Stanley's build quality has remained consistent across production years, and the brand's reputation for reliability in hand tools carries over here.

Where this kit shows its limitations is in the absence of a self-clamping mechanism. You'll need a helper or a clamp to hold the jig steady, especially on hollow-core doors that can shift during drilling. That said, for the price point, it's a legitimate entry point for the category.

Pros:

• Affordable price point for occasional use
• Bi-metal hole saws cut both wood and metal doors
• Compact, lightweight design is easy to maneuver
• Trusted Stanley Black & Decker build quality

Cons:

• No self-clamping mechanism — requires a second pair of hands
• Fewer accessories than competing kits at similar price ranges

2. Milescraft 1338 Lock Mate PLUS — Best Self-Clamping Kit

The Milescraft 1338 Lock Mate PLUS is built for professionals and serious DIYers who install door hardware regularly. Its standout feature is a self-clamping design that attaches to the door without screws, hardware, or surface damage — you simply position it and it grips the door edge on its own. This eliminates one of the most frustrating aspects of lock installation: managing the jig while simultaneously trying to keep your drill aligned.

The kit accommodates doors ranging from 1-3/8 inches to 1-3/4 inches in thickness, covering virtually every residential interior and exterior door on the market. The included bi-metal cobalt alloy hole saws — a 2-1/8-inch and a 1-inch — are capable of cutting through solid and hollow-core wood as well as metal doors without premature dulling. Cobalt content in the saw teeth extends service life substantially beyond standard bi-metal configurations.

Milescraft has engineered the Lock Mate PLUS for repeat use. Contractors who install multiple locks per week report the clamping mechanism holds up through hundreds of cycles. The only note of caution: users who work exclusively on very thin hollow-core doors (under 1-3/8 inches) will find the lower thickness limit binding.

Pros:

• Self-clamping — attaches without screws and causes zero surface damage
• Cobalt alloy bi-metal hole saws handle wood and metal doors
• Adjustable for 1-3/8" and 1-3/4" door thicknesses
• Professional-grade durability for high-volume use

Cons:

• Higher price point than entry-level kits
• Not suited for doors thinner than 1-3/8 inches

3. IRWIN Tools Door Lock Installation Kit (3111002) — Best Complete Kit

IRWIN's 3111002 kit stands out for the sheer breadth of what's included in the box. Beyond the standard jig and hole saws, you get a double-sided jig, a 3/8-inch mandrel, a bolt plate template, a custom router bit, and a hinge plate template. This is one of the most complete door preparation kits available at a mid-range price — a contractor installing a full door slab from scratch has every tool needed to do the job in a single purchase.

The bi-metal hole saws cut cleanly through both metal and wood doors, and the double-sided jig design allows you to align both face bore and edge bore holes from a single setup, reducing cumulative alignment error. IRWIN's kits fit all standard interior and exterior doors, making it versatile across residential projects. The included hinge plate and bolt plate templates are often purchased separately with competing kits, adding genuine value here.

Build quality on the jig itself is solid, though heavy professional users report that the plastic body can show wear after extended use. For the DIYer who installs a few doors per year or the light-duty contractor, this kit delivers excellent value and capability in a single package.

Pros:

• Includes hinge plate template and bolt plate template — competitors often omit these
• Double-sided jig reduces alignment error on face and edge bores
• Bi-metal hole saws work on metal and wood doors
• Fits all standard interior and exterior door sizes
• Custom router bit included for latch plate mortise

Cons:

• Plastic jig body shows wear under heavy professional use
• No self-clamping — manual positioning required

4. DEWALT Door Lock Installation Kit D180004 — Best Overall

DEWALT's D180004 earns the best-overall designation in 2026 by solving the two problems that frustrate users most: alignment and surface damage. The C-clamp design clamps to the door edge without tools, leaving no marks on the door face. Once clamped, the jig holds rock solid while you drill — no helper required, no shifting mid-cut.

The dual adjustable bushings accept both standard backsets (2-3/8 inch and 2-3/4 inch) and both common door thicknesses (1-3/8 inch and 1-3/4 inch), which means one kit handles virtually every door in a standard residential build. The alignment window built into the hole saw setup lets you visually confirm the drill is starting straight before committing — a small detail that prevents the majority of installation errors. Taller bushings deliver more drill guidance depth than most competing designs, reducing bit wander on longer cuts.

DEWALT's name carries weight in the contractor market for a reason. The jig is constructed to handle job-site conditions, not just weekend garage use. Users across contractor forums consistently rank this kit at or near the top for repeatability and accuracy. If you're upgrading your home's entry hardware and want a clean, professional result the first time, this is the kit you reach for. Pair it with a proper deadbolt for a complete security upgrade — our guide to 7 home security weak points explains why the door lock is the most critical layer.

Pros:

• C-clamp design is tool-free and leaves no surface damage
• Alignment window confirms straight drilling before you start
• Two adjustable bushings cover both standard backsets and door thicknesses
• Taller bushings reduce bit wander on longer cuts
• DEWALT build quality rated for professional job-site use

Cons:

• Does not include a hinge plate template
• Slightly higher price than Stanley and IRWIN entry-level options

5. Milwaukee 49-22-4073 Door Lock and Deadbolt Installation Kit — Best Professional Grade

Milwaukee's 49-22-4073 kit is engineered for the professional who installs locksets and deadbolts daily. The polycarbonate body is transparent, which allows you to monitor the cut in real time — a practical advantage that purely opaque jigs cannot match. The auto-centering drill guide and non-slip clamp work together to stabilize the jig against the door face without surface damage, and the two-step process (clamp and drill) is as fast as lock preparation gets.

The included ice-hardened hole saws — a 2-1/8-inch for the lockset bore and a 1-inch for the latch bore — are Milwaukee's hardened steel formulation, rated for extended cutting cycles without sharpening. The side-access slot for plug removal is a detail that experienced installers will immediately appreciate: instead of fumbling with a screwdriver to extract the wood plug from inside the saw, you can push it out from the side, cutting prep time on each door significantly. An anti-splinter depth stop prevents blowout on the exit side of the cut.

The full accessory list is comprehensive: auto-centering guide, anti-splinter depth stop, 2-1/8" and 1" ice-hardened hole saws, small arbor and pilot bit, arbor adaptor and spacer, 3/32" and 1/8" drill bits. Professionals who install 10 or more locks per week will recover the premium price within the first month through time savings alone.

Pros:

• Transparent polycarbonate body for real-time visual monitoring
• Side-access plug removal slot eliminates fumbling with screwdrivers
• Ice-hardened hole saws rated for extended professional use
• Anti-splinter depth stop prevents blowout on exit side
• Comprehensive accessory package — all bits and adaptors included

Cons:

• Premium price point — highest in this category review
• Drill/driver not included despite professional positioning

6. KATA 1-3/8" – 1-3/4" Door Lock Installation Kit — Best for Beginners

The KATA kit targets the homeowner replacing a single interior door lock who doesn't need a professional-grade kit and doesn't want to overspend. The U-type adjustable plastic guide template is straightforward to set up, and the package includes everything required for a complete installation: a 2-1/8-inch hole saw, a 1-inch hole saw, and an arbor with pilot bit. The 50mm saw blade depth handles standard door thickness without issue.

Carbon steel construction on the hole saws is the honest trade-off at this price point. Carbon steel cuts wood effectively but won't survive repeated cuts through metal doors or extended high-volume use the way bi-metal or cobalt variants will. For wooden residential doors — the most common scenario for a first-time installer — the KATA performs the job cleanly. The reinforced plastic guide template is more rigid than cheaper alternatives, reducing flex during drilling that can cause off-center holes.

Setup is simple enough that a first-time user can read the basic instructions and make a clean bore on their first attempt. The KATA is not a kit you'll reach for on a metal commercial door or a heavy-duty exterior slab, but it delivers accurate results on the wooden interior doors it's designed for.

Pros:

• Affordable entry point for occasional home use
• Complete package — hole saws, arbor, and guide template all included
• Reinforced plastic template minimizes flex during drilling
• Covers 1-3/8" and 1-3/4" door thicknesses

Cons:

• Carbon steel saws — not rated for metal doors or heavy professional use
• No self-clamping or C-clamp design

7. Kwikset 92640-001 Electronic Keypad Deadbolt — Best Smart Lock Pairing

The Kwikset 92640-001 is included here as the logical next step after you've bored your holes — a contemporary electronic keypad deadbolt that installs with just a screwdriver and elevates your door security meaningfully. The motorized deadbolt delivers 1-touch locking: press the Kwikset button and the bolt throws automatically. No key, no manual turning of the thumb-turn. For exterior doors where you're carrying groceries or managing kids, that convenience is tangible.

Keyless entry is managed through a customizable keypad that supports six user codes plus temporary codes valid for a single use — practical for service personnel or short-term guests. The automatic locking timer is configurable from 10 to 99 seconds, so you define how long the door stays unlocked after entry. Low battery indication gives you advance warning before you're locked out, and the satin nickel finish is durable and matches most contemporary door hardware. Kwikset rates this unit for exterior door installation specifically, where keyed entry and security are both required.

Installation requires measuring your door's backset, cross bore, and thickness first — the kits reviewed above handle that preparation. This lock fits standard residential door prep, making it a natural companion purchase for anyone installing new hardware from scratch. For additional smart lock options at different price tiers, see our best access control keypads guide.

Pros:

• 1-touch motorized locking — no manual key required
• Six programmable user codes plus one-time temporary codes
• Auto-lock timer configurable from 10 to 99 seconds
• Low battery warning prevents unexpected lockouts
• Screwdriver-only installation — no special tools required

Cons:

• Battery-dependent — failure point in power-out or dead-battery scenarios
• No Wi-Fi or app connectivity — codes managed directly on keypad only

How to Pick the Best Door Lock Installation Kit

Clamping Mechanism: Self-Clamping vs. Manual Positioning

The clamping mechanism is the single most impactful variable in installation accuracy. Self-clamping and C-clamp designs (Milescraft, DEWALT, Milwaukee) hold the jig to the door independently, freeing both hands for the drill. Manual-positioning jigs (Stanley, IRWIN, KATA) require a second person or an external clamp to keep alignment during cutting. If you're installing locks solo, prioritize a self-clamping or C-clamp design to avoid the most common source of off-center bores.

Hole Saw Material: Carbon Steel vs. Bi-Metal vs. Cobalt

The material of your included hole saws determines what you can cut and how long the saws last:

• Carbon steel (KATA): Cuts wood effectively. Not rated for metal doors. Lower price, shorter service life under repeated use.
• Bi-metal (Stanley, IRWIN, DEWALT): Cuts both wood and metal. Standard professional choice for residential work. Good service life.
• Bi-metal cobalt alloy (Milescraft, Milwaukee): Highest heat resistance and edge retention. Best for high-volume professional use or difficult materials including metal doors. Longest service life.

For a single wood door replacement, carbon steel is adequate. For any metal door or repeated professional use, invest in bi-metal or cobalt.

Door Thickness and Backset Compatibility

Residential doors fall into two thickness standards: 1-3/8 inch (interior) and 1-3/4 inch (exterior). Most full-featured kits handle both. Backsets — the distance from the door edge to the center of the bore — also come in two standard sizes: 2-3/8 inch and 2-3/4 inch. Confirm your replacement lock's backset before selecting a kit, and verify the kit's adjustable bushings or template positions cover both your door thickness and your backset. DEWALT's dual-bushing system is one of the clearest implementations of this flexibility.

Included Accessories: What Separates Kits

Beyond the jig and hole saws, kit contents vary significantly. Evaluate what's included against what your project requires:

• Mandrel / arbor with pilot bit: Required for driving the hole saw. Most kits include one; verify before purchase.
• Bolt plate template: Marks the latch plate mortise on the door edge. IRWIN includes this; most others do not.
• Hinge plate template: Useful for full door-slab installation. IRWIN is the only kit in this review to include it.
• Router bit: For cutting the latch plate mortise precisely. IRWIN includes a custom router bit; others assume you have one.
• Anti-splinter depth stop: Milwaukee's feature that prevents blowout on the exit face of the bore.
• Plug removal access slot: Milwaukee's side-slot design that speeds up plug extraction between cuts.
