Naomi Tanaka A door is only as strong as the lock behind it, and the best deadbolts do the heavy lifting your latch never could. A quality deadbolt resists kick-ins, drill attacks, and lock-picking far better than a spring latch alone. But the market is crowded with finishes, grades, and keyways that make choosing harder than it should be. This guide cuts through the noise. You will learn how residential security grades work, which bolt fits your door, and which model matches your budget and use-case. We compared 10 top-rated locks on real specs, then ranked them so you can decide fast.

Pros
- 1-inch hardened steel deadbolt bolt with a spinning anti-drill core resists drill-out attack attempts
- Grade 1 BHMA classification, the top classification for residential security, durability, and finish
- Anti-pick pins add resistance against lock-picking beyond a standard pin-tumbler mechanism
- Fits standard 2-3/8" or 2-3/4" backset doors with thickness from 1-3/8" to 1-7/8" without special ordering
- Includes a reinforced strike plate with 3-inch screws to resist kick-in forced entry attempts
Cons
- Keyed from one side only, so the interior uses a thumbturn rather than a second keyhole, which some buyers specifically avoid near glass-paneled doors for security reasons
- Installation still requires the door already be bored for a standard deadbolt, and includes only 2 keys with no spares in the box
- Available in this listing in Satin Nickel only, so matching other hardware finishes elsewhere requires checking undertone compatibility
The deadbolt uses a 1-inch bolt built around a hardened steel spinning pin, designed so a drill bit skates off the core rather than cutting through it, paired with anti-drill plates and anti-pick pins that resist common bypass techniques. This combination earned it a Grade 1 BHMA classification, the top tier for residential security, durability, and finish under that certification system.
It is keyed from one side only, meaning the exterior takes a key while the interior operates with a simple thumbturn rather than a second keyhole. That is a common setup for entry doors without adjacent glass, though homes with glass panels near the door sometimes prefer a double-cylinder deadbolt instead, since a single-cylinder lock can be reached and turned if a nearby pane is broken.
Self-aligning screw holes are built in to make installation straightforward with just a screwdriver, and the universal latch slides into place without extra tools to fit standard doors with either a 2-3/8" or 2-3/4" backset. Door thickness compatibility runs from 1-3/8" to 1-7/8", covering the great majority of standard residential exterior doors.
An integrated strike reinforcer ships with 3-inch screws, meant to anchor into the door frame's structural wood rather than just the thin jamb trim, adding resistance against kick-in forced entry. The lock fits both right- and left-handed doors without needing a different part number. Doors that fall outside the standard backset or thickness ranges, such as older or non-standard builds, should be measured carefully before ordering since this is not an adjustable-fit universal design in that respect.
This listing comes in a Satin Nickel finish, a neutral tone that pairs with most modern and transitional hardware finishes elsewhere on a home's exterior. The deadbolt ships with 2 keys, with no spares included, so anyone wanting backup keys made will need to visit a hardware store or locksmith after installation.
Schlage backs the mechanical function and finish with a limited lifetime warranty, covering the lock body and coating against manufacturing defects over the long term rather than just an initial return window. Because the deadbolt is single-cylinder and keyed from one side, it is best suited to standard entry doors without immediately adjacent glass panels, where a thumbturn interior poses less of a security tradeoff.

What a deadbolt actually does
A deadbolt throws a solid metal bolt deep into the door frame. Unlike a latch, it cannot be pushed back with a card or knife. That single feature blocks the most common forced-entry method.
Deadbolts come in three main types. A single-cylinder deadbolt uses a key outside and a thumbturn inside. A double-cylinder needs a key on both sides, useful near glass panels. A one-sided deadbolt has a thumbturn only, for doors that never need outside access.
Most homes want a single-cylinder model. It is fast to operate in an emergency and meets code in most areas. Save double-cylinder locks for doors with sidelights an intruder could break to reach the turn.
How to choose the best deadbolts for your door
Four criteria matter more than brand loyalty. Get these right and almost any reputable lock will serve you for years.
Security grade
ANSI/BHMA rates locks Grade 1, 2, or 3. Grade 1 survives the most strikes and turns in testing. The Schlage B60 carries the “Highest Residential Security” claim and is a smart default for exterior doors.
Grade 2 is the commercial baseline and plenty for interior or lighter-use doors. The Schlage B560 Commercial is a Grade 2 unit built for rental units and side entries that see heavy traffic.
Bolt throw and backset
Look for a full 1-inch bolt throw. A short bolt barely reaches the frame and pulls free under pressure. Backset is the distance from the door edge to the bore center, usually 2-3/8 or 2-3/4 inches. Good locks ship adjustable to fit both.
Rekey and key control
If you move often or share keys, rekeyable cylinders save money. Kwikset SmartKey lets you reset the lock to a new key in seconds without a locksmith. The Kwikset 660 SmartKey also adds pick and bump resistance at a low price.
Finish and door thickness
Match the finish to your other hardware: satin nickel, matte black, or antique brass. Confirm the lock fits standard 1-3/8 to 1-3/4 inch doors. Nearly all models here do, but thick custom doors need a check first.
Best deadbolts by use-case
Rather than crown one winner for everyone, match the lock to how you actually live. Here are the picks that stand out for specific needs.
Best overall
The Schlage B60 earns the top spot on proven reliability. With 6024 reviews at a 4.6 rating and a $35.47 price, it balances top-tier security and value better than anything else on the list. It is keyed one side with a thumbturn inside — the right setup for most front doors. It is not for you if you want SmartKey rekeying, which Schlage does not offer.
Best budget
At $19.97, the Kwikset 660 with Microban is the cheapest solid option here. It adds an antimicrobial coating on the touch surfaces, a small bonus on a high-touch entry point. The 4.5 rating across 234 reviews shows it holds up. Skip it if you want a Grade 1 rating for a primary exterior door.
Best for interior and one-sided doors
Some doors never need a key outside — a garage-to-house door or a basement entry. The Schlage B81 is a non-keyed, one-sided deadbolt with a thumbturn only. At $29.01 with the highest residential security rating, it locks up tight without a cylinder to pick.
Best matte black combo set
If you want a deadbolt and matching knob in one box, the Schlage FB50 Plymouth pairs a single-cylinder deadbolt with a keyed entry knob in matte black. It is a clean way to secure and re-hardware a door at once. Prefer a lever over a knob? The Schlage FB50 Latitude swaps in a modern lever for easier grip.
Best for rentals and heavy use
Landlords and busy side doors need durability over looks. The Schlage B560 Commercial ships with a C keyway, latch, and strike, built to a Grade 2 commercial standard at $77.51. It costs more, but it is made to cycle thousands of times without loosening.
Your practical buying guide: sizes, specs, and compatibility
Before you order, take five minutes with a tape measure. These details decide whether the lock drops in or forces a return.
First, measure your bore hole. The standard cross-bore is 2-1/8 inches, and the edge bore is 1 inch. Every model here fits the standard prep. Second, confirm the backset, either 2-3/8 or 2-3/4 inches — adjustable latches cover both.
Third, check door thickness against the 1-3/8 to 1-3/4 inch range. Fourth, decide keying. Do you want new locks keyed alike so one key opens everything? Schlage and Kwikset both offer keyed-alike ordering, which is worth planning across multiple doors at once.
If a smart lock or keypad is on your wish list, weigh it before buying mechanical. Our roundup of the best digital deadbolts with keypad and app control compares battery life and connectivity so you can decide between a key and a code. For the entry that matters most, the guide to the best deadbolts for front doors digs deeper into strike-plate reinforcement and Grade 1 picks.
Common mistakes to avoid
Even a Grade 1 lock fails if you install it wrong or pair it with a weak frame. Watch for these traps.
Ignoring the strike plate. The bolt is only as strong as what it enters. Swap the short screws for 3-inch screws that bite into the wall stud, not just the jamb. This one change stops most kick-ins.
Choosing double-cylinder near no glass. A key-both-sides lock is a fire hazard on a solid door because you cannot leave fast in the dark. Only use it where glass sits within arm’s reach of the turn.
Buying on finish alone. A gorgeous antique brass set like the Schlage FB50 Georgian is worth it only if the security grade fits the door’s job. Match the spec first, the color second.
Skipping rekey planning. If you just moved, rekey or replace every exterior lock. You never know who holds a copy. A SmartKey model or a locksmith visit closes that gap on day one.
For a broader look at securing every entry point, our guide to the best home deadbolts for whole-house security covers pairing exterior and interior locks into one coherent plan.
Finishes and style pairing
Hardware is jewelry for your door, so coordinate it. Satin nickel is the safest neutral and hides fingerprints well. The Kwikset 660 Satin Nickel is a clean, low-cost way to match existing brushed hardware.
Matte black reads modern and hides wear on high-traffic doors. The Schlage FB55 Bowery combo brings that black finish with a knob and Collins trim for a full front-door refresh. Antique brass suits traditional and craftsman homes but shows scratches faster on a busy entry.
Frequently asked questions
Are Schlage or Kwikset deadbolts better?
Both are reliable, but they lead in different areas. Schlage tends to win on raw security ratings, with more Grade 1 options like the B60. Kwikset shines on price and its SmartKey rekeying feature. Pick Schlage for maximum strength and Kwikset for easy rekeying on a budget.
What deadbolt grade do I need for a front door?
Aim for a lock rated for the highest residential security, equivalent to Grade 1. That grade survives the most strikes and turns in ANSI testing. A Grade 2 lock is fine for interior or side doors, but your main entry deserves the strongest bolt you can fit.
Can I install a deadbolt myself?
Yes, if your door already has the standard 2-1/8 inch bore. Installation takes about 20 minutes with a screwdriver and follows the included template. Cutting a new bore into a blank door is harder and may call for a drill jig or a pro. Always upgrade the strike screws while you are there.
What is the difference between single and double cylinder?
A single-cylinder deadbolt uses a key outside and a thumbturn inside for fast exit. A double-cylinder needs a key on both sides, which stops someone from reaching through broken glass to unlock the door. Double-cylinder locks add security near windows but can trap you in a fire, so use them only where necessary.
Should I rekey or replace an old deadbolt?
Rekey if the lock is still solid and just needs new keys, which is cheaper and greener. Replace if the bolt is worn, the grade is low, or the finish is failing. After moving into any home, rekey or replace every exterior lock so old keys no longer work.
The bottom line
A deadbolt is the cheapest serious upgrade you can make to your home’s security, and any lock on this list beats a bare latch. For most doors, the Schlage B60 is the safe, proven pick, while the Kwikset 660 covers tight budgets and easy rekeying. Match the grade to the door, reinforce the strike plate, and you will get years of quiet, dependable protection. Measure your bore, choose your finish, and lock it in.
