Quick Comparison: Top Residential Lock Upgrades
The best residential lock security upgrades combine a Grade 1 mechanical deadbolt with reinforced door hardware, then add smart features only where they solve a real problem. At A Ej Locksmith, we have spent 43 years installing and repairing locks, and the pattern is consistent: a solid deadbolt and a hardened frame stop more forced entries than any app.
Quick Picks:
Best Overall Mechanical: Schlage B60N, Grade 1 deadbolt named best overall in a home-security roundup
Best High-Security: Medeco Maxum, top high-security pick for pick and drill resistance
Best Smart Deadbolt: Schlage Arrive Smart WiFi Deadbolt, named a top pick for simple installation
Best PIN Keyless: Nest x Yale Smart Lock, a leading option for PIN-only entry
Below, we break down what actually matters: mechanical grades, smart lock trade-offs, and the frame reinforcement most guides skip.
Upgrade | Type | Best For | Priority |
Schlage B60N | Mechanical deadbolt | Most exterior doors | First |
Medeco Maxum | High-security mechanical | High-risk entry points | Second |
Schlage Arrive Smart WiFi Deadbolt | Smart deadbolt | Remote and app access | Third |
Nest x Yale Smart Lock | Smart keypad lock | PIN-based keyless entry | Third |
Strike plate + frame screws | Reinforcement | Every entry door | First |
Best Deadbolt Locks for Home Security
The best deadbolt locks for home security carry a Grade 1 rating, which measures resistance to forced entry, and they fit a standard 2-1/8 inch bore. Grade matters more than brand marketing. According to ANSI/BHMA lock grading standards, Grade 1 is the highest residential rating for strength and durability.
Grade 1 Mechanical Deadbolts: Schlage B60N, Kwikset 980, and Medeco Maxum
Three mechanical deadbolts dominate this category. Each earns its place for different reasons.
Schlage B60N: Named the best overall lock in a home-security roundup, and identified as Grade 1.
Kwikset 980: Described by Wirecutter as Kwikset's only Grade 1-rated deadbolt priced for residential use. A solid value pick.
Medeco Maxum: Listed as the high-security pick in the same roundup. Best where pick resistance matters.
A common mistake is buying a deadbolt by finish or price alone. The bolt throw and cylinder quality decide how it holds up under force.
Pro Tip Check the bolt throw before you buy. A deadbolt that extends at least 1 inch into the strike plate resists shimming far better than a short-throw bolt. Most homeowners never check this, and it is the single easiest spec to verify in the store.
High-Security Mechanical Picks: Medeco Maxum and Mul-T-Lock
High-security locks add restricted keyways and hardened pins that defeat picking and drilling. Medeco and Mul-T-Lock both appear among brands offering Grade 1 deadbolts for residential exterior doors.
The trade-off is key control. Restricted keys cannot be copied at a hardware store, which protects you but adds friction when you need a spare.
Smart Lock vs Deadbolt: Which Upgrade Fits Your Door?
A smart lock adds convenience and access control; a deadbolt adds raw physical resistance. The best residential lock security upgrades often use both: a Grade 1 deadbolt on the main door and a smart lock where you need guest or remote access. Neither replaces the other.
Here is how the two compare on the factors that decide the purchase:
Feature | Mechanical Deadbolt | Smart Lock |
Forced-entry resistance | High (Grade 1) | Varies by model |
Remote access | No | Yes, via app |
Battery dependency | None | Yes, needs backup |
Guest codes | No | Yes |
Price tier | Lower | Higher |
If your priority is stopping a break-in, buy the deadbolt first. If your priority is letting in a contractor while you are at work, buy the smart lock. Most homes benefit from the deadbolt as the foundation.
Smart Lock Installation: What the Process Actually Involves
Smart lock installation involves swapping the existing deadbolt for the smart unit, then pairing it to your phone. The Consumer Product Safety Commission notes that improper door hardware installation can compromise both security and safe exit, so fit matters.
The process follows a predictable sequence:
Remove the existing deadbolt and note the bore size
Confirm the new lock fits the door thickness and backset
Install the exterior and interior halves
Connect the adapter and batteries
Pair the lock to the app and set codes
Test locking, unlocking, and the backup key
Compatibility and Installation Checks Before You Buy
Check three things before ordering. First, door thickness: most smart locks fit 1-3/8 to 1-3/4 inch doors. Second, backset: measure from the door edge to the center of the bore, usually 2-3/8 or 2-3/4 inches. Third, existing bore diameter, which should be 2-1/8 inches for most deadbolts.
If any measurement is off, you may need an adapter kit or a different model. We handle these checks on site.
Door Strike Plate Reinforcement and Frame Hardening
Door strike plate reinforcement is the upgrade most homeowners skip, and it is the one that matters most. A Grade 1 deadbolt is only as strong as the wood it bolts into. If the strike plate is held by short screws, a kick can split the jamb and defeat the lock entirely.
The fix is straightforward:
Replace the standard strike plate with a heavy-duty steel plate
Use 3-inch screws that reach the wall framing, not just the jamb
Add a jamb reinforcement plate or a security strike box
Check the hinges for loose screws and replace with longer ones
Watch Out Skipping frame reinforcement is the most common mistake we see. A homeowner spends on a Grade 1 deadbolt, then the door frame splits on the first hard kick because the strike plate was held by half-inch screws. The lock was never the weak point.
Cost and Value by Upgrade Level
Cost and value depend on how far you go and whether you install it yourself. We do not publish fixed prices here because every door is different.
Upgrade Level | What It Includes | Typical Hardware Cost | Typical Installed Cost | Value Focus |
Entry level | Grade 1 deadbolt swap | $40-$120 | $150-$300 | Best forced-entry resistance per dollar |
Mid level | Deadbolt plus heavy-duty strike plate, 3-inch screws, jamb reinforcement | $60-$160 | $200-$400 | Closes the frame gap that defeats the lock |
Full level | Smart lock plus reinforced frame | $150-$350 | $350-$650 | Adds access control to physical strength |
Where the Money Actually Goes
Three line items drive the total:
The lock itself. A Grade 1 mechanical deadbolt is an effective way to buy real forced-entry resistance. High-security mechanical locks with restricted keyways and hardened pins offer advanced security, and the key-control trade-off is real: restricted keys cannot be copied at a hardware store.
The reinforcement. A heavy-duty strike plate, a jamb reinforcement plate, and 3-inch screws are important parts, and they are a high-return dollar in the whole project. A Grade 1 deadbolt in a soft jamb is a Grade 1 deadbolt that fails on the first kick.
The smart layer. Smart deadbolts vary widely by model, connectivity, and finish. The cost is not just the lock: it is batteries, a hub or Wi-Fi you already pay for, and the time to manage codes and firmware.
Ongoing and Hidden Costs
Budget for the costs that do not show up on the shelf tag:
Batteries. Four AA batteries every six to twelve months per smart lock.
Re-keying or new cylinders. If you move in or lose a key, re-keying a mechanical lock is cheap; replacing a restricted-keyway cylinder is not.
Professional installation. A locksmith call for a single deadbolt is often a minimum-service charge. Bundling multiple doors into one visit lowers the per-door cost.
Emergency calls. A lockout after a smart lock battery dies is a service call you can avoid with a scheduled battery swap and a stored backup key.
The Value Verdict
The mid level offers significant value. If your budget only stretches to one upgrade, buying the Grade 1 deadbolt and the reinforcement together is highly effective, the frame is where forced entries succeed, and it is an effective place to close the gap. Add the smart layer only when remote or guest access solves a problem you actually have.
Key Takeaway Spend on the frame before you spend on the app. A reinforced Grade 1 deadbolt at the mid level offers strong security. Failure Modes, Backup Access, and Privacy Every lock fails in some way, and planning for it separates a good install from a frustrating one. Smart locks fail when batteries die, when Wi-Fi drops, or when the app loses sync. Mechanical locks fail when keys are lost or cylinders wear out. Protect yourself with three habits: Keep a backup key stored outside the home, not in the lock Replace smart lock batteries on a schedule, not when they die Set a temporary access code for guests and delete it after Privacy deserves a mention too. Some smart locks log every entry and connect to cloud accounts. If that concerns you, choose a model with local storage or a keypad-only design. A keypad lock with no app connection still gives you keyless entry without the data trail. The most reliable setup pairs a Grade 1 mechanical deadbolt with reinforced frame hardware, then adds a smart lock only where remote or guest access is genuinely needed.

Frequently Asked Questions
What is the most secure residential door lock?
A Grade 1 mechanical deadbolt from a brand like Schlage, Medeco, or Mul-T-Lock offers the highest pick and forced-entry resistance for most homes. The Schlage B60N and Kwikset 980 are both Grade 1-rated, and Medeco Maxum adds high-security key control. Pairing a Grade 1 deadbolt with door strike plate reinforcement and a solid wood or metal door frame gives you the strongest residential lock upgrades available.
Are smart locks more secure than traditional deadbolts?
It depends on the model. A high-quality smart lock like the Yale Assure Lock 2 or Schlage Encode Plus uses the same deadbolt mechanism as a mechanical lock but adds keypad or smartphone access, automatic locking, and temporary access codes. However, a Grade 1 mechanical deadbolt such as the Schlage B60N or Kwikset 980 typically has a stronger bolt and cylinder. Many homeowners combine both: a smart lock on the main entry and Grade 1 mechanical deadbolts on secondary doors.
Can a locksmith install a smart lock?
Yes. A licensed locksmith can handle smart lock installation, including checking door compatibility, drilling new holes if needed, and connecting the lock to your Wi-Fi or smart-home system. Professional installation ensures the lock aligns correctly with the strike plate and that the deadbolt extends fully into the frame. If you are not comfortable with DIY electronics or your door has an unusual backset, hiring a locksmith is the safer choice.
Should I replace my deadbolt or reinforce the door frame?
Both matter. A Grade 1 deadbolt like the Schlage B60N or Kwikset 980 resists picking and drilling, but if the door frame or strike plate is weak, a forced entry can still succeed. Door strike plate reinforcement with a heavy-duty metal plate and 3-inch screws anchors the lock into the wall stud, which is one of the most cost-effective residential lock upgrades. For a complete security upgrade, replace the deadbolt and reinforce the frame at the same time.
How much does it cost to upgrade residential locks?
Costs vary by upgrade level. Professional installation and door reinforcement add labor costs. For exact pricing on your home, contact a licensed locksmith who can assess your doors and recommend the right mix of mechanical and smart upgrades.
