Best Deadbolt Locks 2026: 7 Locks Tested — Grade 1 Traditional, Smart (HomeKit/Z-Wave) & High-Security Rated

Best Deadbolt Locks for Home Security 2026: Traditional, Smart & High-Security Compared

Your deadbolt is literally your home’s last physical barrier against intruders. 34% of burglars enter through the front door, and most forced entries involve kicking the door in — defeating a weak lock and frame in under 2 kicks. The right deadbolt, properly installed, can withstand hundreds of pounds of force and resist picking, bumping, drilling, and prying.

We’ve tested and researched every major deadbolt brand to rank the best options across three categories: traditional mechanical, smart/keyless, and high-security. Here’s what actually matters in 2026.

Understanding ANSI/BHMA Grades: The Only Rating That Matters

Before comparing individual locks, you need to understand the grading system. The ANSI/BHMA (American National Standards Institute / Builders Hardware Manufacturers Association) grade is the industry standard for measuring lock security and durability.

Rule of thumb: Every exterior door should have at minimum a Grade 2 deadbolt. Grade 1 is strongly recommended for front doors, back doors, and any door visible from the street. Grade 3 deadbolts should never be used on exterior doors.

UL 437 is a step above Grade 1 — it adds requirements for drill resistance, saw resistance, and advanced pick resistance. Only high-security locks like Medeco, Mul-T-Lock, and ASSA Abloy products carry this certification.

Best Traditional Deadbolts

1. Schlage B60N — Best Overall Traditional Deadbolt (9.5/10)

Price: $40–60 | Grade: ANSI/BHMA Grade 1

The Schlage B60N is the deadbolt that locksmiths actually install on their own homes. It’s the gold standard for traditional deadbolts — Grade 1 rated, with anti-pick shield, anti-pry shield, and a hardened steel anti-drill pin protecting the cylinder.

Why it wins: The B60N gives you 90% of the security of a $200+ high-security lock at a quarter of the price. The included reinforced strike plate with 3-inch screws is critical — most break-ins defeat the frame, not the lock, and long screws anchor into the wall stud behind the frame.

Limitations: Standard keyway means keys can be duplicated at any hardware store (good for convenience, less ideal for key control). No smart features. If you need restricted key duplication, step up to Medeco.

2. Medeco Maxum — Best High-Security Deadbolt (9.3/10)

Price: $200–250 | Grade: ANSI Grade 1 + UL 437

Medeco’s patented rotating pin technology makes this lock virtually impossible to pick, bump, or duplicate keys without dealer authorization. The pins must be both lifted AND rotated to the correct angle — a complexity that defeats even skilled lock pickers.

Why it wins: If your threat model includes lock picking, bump keys, or unauthorized key duplication, Medeco is the answer. The UL 437 certification means it’s been tested against drills, saws, and sophisticated attacks that standard Grade 1 locks don’t face.

Limitations: Expensive. Key replacement requires a visit to an authorized Medeco dealer with ID verification. Overkill for most residential situations — but perfect for high-value homes, vacation properties, and anyone who takes physical security seriously.

3. Kwikset 980 — Best Budget Deadbolt (8.0/10)

Price: $25–35 | Grade: ANSI/BHMA Grade 1

The Kwikset 980 delivers Grade 1 security at a budget price. Its standout feature is SmartKey re-keying — you can change the lock to work with a new key in seconds using the included tool, without calling a locksmith.

Why it works: At under $35, there’s no reason to use a Grade 3 deadbolt. The 980 gives you Grade 1 protection at a Grade 3 price. SmartKey is genuinely useful — moved into a new home? Re-key in 15 seconds.

The SmartKey controversy: In 2013, a security researcher demonstrated that early SmartKey locks could be defeated with a screwdriver and specialized tool. Kwikset has since redesigned the mechanism with additional security features, but security-conscious buyers may prefer Schlage’s traditional pin tumbler design. For most homes, the current SmartKey generation is adequate.

Best Smart Deadbolts

Smart deadbolts eliminate the biggest vulnerability of traditional locks: physical keys. No keys to lose, copy, or hide under the mat. Instead, you get PIN codes, fingerprints, phone unlock, and remote access. For our full smart lock guide, see Best Smart Locks for Home Security 2026.

4. Schlage Encode Plus — Best Smart Deadbolt (9.5/10)

Price: $280–320 | Grade: ANSI/BHMA Grade 1

The Encode Plus is the only smart deadbolt that combines ANSI Grade 1 physical security with Apple Home Key. Tap your iPhone or Apple Watch to unlock — as fast as tapping a credit card. Built-in WiFi means no hub required.

Why it wins: Most smart locks sacrifice physical security for digital features — they’re Grade 2 or ungraded. The Encode Plus is Grade 1, meaning it matches the Schlage B60N’s kick/drill/pick resistance while adding smart features. Apple Home Key is the fastest, most secure unlock method available (NFC + Secure Enclave encryption).

Security system integration: Works natively with Abode (via HomeKit/Z-Wave), Apple Home automations, and Amazon Key for deliveries. Set it to auto-lock when your Abode geofence triggers away mode.

5. Yale Assure Lock 2 — Best Multi-Platform Smart Deadbolt (9.2/10)

Price: $200–280 | Grade: ANSI/BHMA Grade 2

Yale’s modular approach is brilliant — buy the lock once, then swap the wireless module as standards evolve. Currently available with WiFi, Bluetooth, Apple Home Key (via Matter), or Z-Wave modules.

Why it wins: The Matter module makes this the most future-proof smart lock. It works with Apple Home, Google Home, Samsung SmartThings, and Amazon Alexa simultaneously — no ecosystem lock-in. The design is also significantly sleeker than competing smart deadbolts.

Why not #1: ANSI Grade 2 instead of Grade 1. For most homes this is fine, but if physical security is your top priority, the Schlage Encode Plus’s Grade 1 rating wins.

6. August WiFi Smart Lock — Best Retrofit Smart Deadbolt (8.5/10)

Price: $200–250 | Grade: N/A (uses your existing deadbolt)

August takes a completely different approach: it installs over your existing deadbolt on the inside of the door. Your current key still works from outside, but you gain smart features — app unlock, auto-lock/unlock, voice control, and guest access.

Why it wins for renters: No exterior changes means landlords can’t object. Your existing deadbolt stays — August just motorizes it from inside. Perfect for renters and anyone who doesn’t want to replace their current lock. Take it with you when you move.

7. Kwikset Halo Touch — Best Fingerprint Smart Deadbolt (8.3/10)

Price: $200–230 | Grade: ANSI/BHMA Grade 2

The Halo Touch adds a fingerprint reader to the deadbolt — stores up to 100 fingerprints with a claimed less than 2% false rejection rate. No phone, no codes, just your finger. Built-in WiFi, no hub needed.

Best for: Families with kids (no codes to remember), elderly users, anyone who finds phone-based unlocking clunky. Fingerprint is the fastest unlock method that doesn’t require carrying anything.

Traditional vs Smart Deadbolt: Which Do You Need?

Our recommendation: For most homeowners in 2026, a smart deadbolt on the front door + traditional Grade 1 deadbolts on other exterior doors is the best combination. You get keyless convenience where it matters most while saving money on secondary doors.

The Strike Plate Problem: Why Your Frame Matters More Than Your Lock

Here’s the dirty secret of home security: most forced entries don’t defeat the lock — they defeat the door frame. A $300 smart lock installed with the standard 3/4-inch screws can be kicked in with one solid hit.

The fix is simple and cheap:

The $5 upgrade everyone should do today: Replace every exterior door’s strike plate screws with 3-inch screws. The short screws that come standard only grip the door frame (soft pine). 3-inch screws anchor into the wall stud behind the frame — dramatically increasing kick resistance. Takes 5 minutes per door.

Deadbolts + Security Systems: The Complete Door Protection Setup

A deadbolt stops physical entry. A security system handles everything else — and makes your deadbolt smarter.

Abode is the best security system for smart lock integration because it supports Z-Wave, Zigbee, AND HomeKit — meaning it works with virtually every smart deadbolt on the market. Set up automations like:

• Leave home → Geofence triggers away mode → all smart locks auto-lock
• Door forced open → Sensor triggers → siren + police dispatch + phone alert with camera footage
• Guest arrives → Temporary code unlocks door → system disarms → lights turn on
• Bedtime → Tap “goodnight” → all doors lock + system arms home mode

Common Lock Attack Methods (And Which Deadbolts Stop Them)

How to Install a Deadbolt (DIY Guide)

Most deadbolt replacements are simple DIY projects if you’re swapping an existing lock. New installations on doors without a deadbolt bore hole require a hole saw and are more involved.

Replacing an Existing Deadbolt (15 Minutes)

1. Remove old lock — unscrew interior plate, pull out both sides
2. Check measurements — bore hole (standard: 2-1/8″), backset (2-3/8″ or 2-3/4″), door thickness (1-3/8″ to 1-3/4″)
3. Install new bolt assembly — slide into edge bore, screw in faceplate
4. Install exterior cylinder — insert from outside, connect tailpiece
5. Install interior thumb turn — align, screw in mounting plate
6. Replace strike plate — use the reinforced strike plate with 3-inch screws (anchor into stud)
7. Test operation — key, thumb turn, and bolt extension should be smooth

Frequently Asked Questions

What ANSI grade deadbolt should I get?

Grade 1 for all exterior doors, always. Grade 2 is acceptable if you’re choosing a smart lock (most smart locks are Grade 2). Never use Grade 3 on an exterior door — it’s designed for interior/closet doors only.

Are smart deadbolts as secure as traditional ones?

Physically, most smart deadbolts are Grade 2 (the Schlage Encode Plus is a notable Grade 1 exception). The digital side adds convenience but also a small attack surface. In practice, smart locks are MORE secure for most people because they eliminate the biggest real-world vulnerability: lost/copied keys and forgotten locks.

Can a locksmith open any deadbolt?

Standard deadbolts (Schlage, Kwikset) — yes, a skilled locksmith can pick them in minutes. High-security locks (Medeco, Mul-T-Lock) — most locksmiths cannot pick them and will need to drill, which is destructive. Smart locks with no keyhole — require different bypass methods entirely.

How often should I replace my deadbolt?

Replace your deadbolt if: it’s more than 15 years old, the bolt is loose or stiff, you’ve moved into a new home (or re-key it), the key is worn and sticking, or you have a Grade 3 lock on an exterior door. Smart lock batteries should be replaced every 6–12 months.

Do I need a deadbolt AND a knob lock?

The knob lock provides convenience (spring latch closes automatically). The deadbolt provides security (1″ hardened steel bolt resists force). Use both — the knob lock for everyday latching, the deadbolt when you leave or at night. Never rely on a knob lock alone for security — they can be bypassed with a credit card in seconds.

What’s the single best security upgrade for my front door?

Replace the strike plate screws with 3-inch screws ($5, 5 minutes). This single upgrade dramatically increases kick resistance by anchoring into the wall stud instead of just the soft door frame. Then pair a Grade 1 deadbolt with a security system like Abode for detection and response.

Growing up with Law and Order and CSI shows taught Isabelle Landau one thing: if people back then had high-quality home security systems, those series would have been way shorter. In our modern world, technology helps us keep burglars away easily, and this is what Izzy studies and writes about: alarm systems, home security, protection systems, and more.
