ANSI Grade 1 vs Grade 2 Deadbolts: What the Numbers Mean
Quick answer: ANSI Grade 1 is the toughest residential rating, Grade 2 is the standard, Grade 3 is too weak for exterior doors. For most Las Vegas homes, a Grade 2 deadbolt plus a reinforced strike plate beats a Grade 1 deadbolt with the stock strike. Spend the upgrade money on the strike before you spend it on the grade. Total installed cost: $130 to $180 for a solid Grade 2 setup, $300 to $500 for a Grade 1 setup with high-security cylinder.
What ANSI/BHMA actually tests
The grading system you see on deadbolt packaging (Grade 1, Grade 2, Grade 3) comes from a joint standard published by the American National Standards Institute and the Builders Hardware Manufacturers Association, usually referenced as ANSI/BHMA A156.36. It is a real test. Locks get sent to certified labs and pounded on. The grade is the result.
The three main test buckets are operating cycles (how many times the lock can be turned before parts fail), security tests (how hard the bolt can be hit before it gives), plus a static load test (how much constant pull force the bolt can resist). There are also material and finish requirements (no peeling chrome, no rusting steel under salt-spray conditions), but for break-in resistance the security and load tests are what matter.
The actual numbers
| Rating | Operating cycles | Hammer strikes (75 ft-lb each) | Static load on bolt | Where it lives |
|---|---|---|---|---|
| Grade 1 | 250,000 | 10 | 360 lb | Commercial, high-end residential |
| Grade 2 | 150,000 | 5 | 250 lb | Standard residential |
| Grade 3 | 100,000 | 2 | 150 lb | Interior doors only (we would not put it on an entry) |
One way to read the cycle test. If you open your front door 10 times a day, that is 3,650 cycles a year. A Grade 1 lock is rated to handle that for roughly 68 years before parts wear out. A Grade 2 lock is rated for 41 years. A Grade 3 lock is rated for 27 years. All three numbers are well past the time most homeowners will own the lock, which is why the cycle rating matters more on rentals and commercial entries with high turnover than on a primary residence.
The hammer test, in plain English
The hammer test is the one most homeowners care about, because it is the closest analog to a kick-in attack. A 75-foot-pound impact is approximately what a hard kick from a 200-pound adult delivers to the door. The bolt face has to absorb that impact without the bolt itself bending or the cylinder freeing.
Grade 1 takes 10 of these strikes and keeps working. Grade 2 takes 5. Grade 3 takes only 2. But here is the part the package does not say. None of those tests involve the strike plate. The bolt is locked into a steel test fixture, not a wooden door jamb with two short screws. In a real kick-in attack on a Las Vegas tract home, the bolt itself is rarely what fails. The jamb wood around the strike plate is what fails. The screws rip out of the wood. The bolt is still intact, just no longer engaged with anything.
Why the strike plate matters more than the grade
If you remember one thing from this article, remember this. The strike plate is the weak link in residential security. Builders use short, half-inch screws to mount the strike plate to the door jamb. The jamb wood is about three quarters of an inch thick. There is almost no purchase. A determined kick rips the screws right out, the strike comes with them, and the door swings open with a still-functional Grade 1 deadbolt dangling from it.
The fix is straightforward and cheap. Replace the strike plate with a heavier-duty one, drive three-inch screws through the jamb wood into the framing stud behind, and the door becomes dramatically harder to defeat. Schlage SG-300, Door Armor MAX, plus Defender Security all sell strike kits in the $20 to $50 range. Install takes 20 minutes with a drill. After this upgrade, a Grade 2 lock with reinforced strike outperforms a Grade 1 lock with stock strike in real-world kick-in resistance, by a wide margin.
So which grade should you actually buy?
For a typical single-family home in Summerlin, Green Valley, Aliante, Centennial Hills, or the central Vegas neighborhoods, Grade 2 is the right pick. The Schlage B60 series, Kwikset 980 series, and Yale 8101 series are all Grade 2 mechanical deadbolts in the $35 to $75 hardware range. Pair with a $20 reinforced strike kit, and total installed cost lands around $130 to $180 for a real upgrade over builder hardware.
For higher-value homes (The Ridges in Summerlin, Anthem Country Club, Red Rock Country Club, Lake Las Vegas, MacDonald Highlands), Grade 1 hardware is worth the upgrade. A Medeco or Mul-T-Lock high-security cylinder in a Grade 1 deadbolt body, plus a reinforced strike, gets you both pick resistance and kick resistance. Total installed cost runs $300 to $500. These also have restricted key blanks, so a former cleaning service or contractor cannot get a copy made at the hardware store.
For rental properties (Spring Valley apartments, Henderson townhomes, North Las Vegas single-family rentals), Grade 2 is more than enough. Tenant turnover is the bigger security concern, and a quick rekey at $20 to $40 per cylinder between tenants matters more than upgrading the grade. We rekey Grade 2 hardware for rental owners across the Vegas Valley on a weekly basis.
For commercial entries (storefronts on Spring Mountain Road, office buildings in Hughes Center, light industrial in North Las Vegas), Grade 1 is the right floor. Commercial doors see far more traffic, and the cycle rating matters more here. A Grade 2 lock on a high-traffic commercial entry will start showing wear inside a couple of years.
How to read a deadbolt package
Manufacturers usually print the grade on the front of the box in big letters, but the spec sheet on the back has the real details. Look for the ANSI/BHMA A156.36 reference number plus the specific grade letter. Watch out for vague phrases like "commercial grade" or "highest security" without the actual ANSI number. Those phrases are marketing speak, not certification.
A few brands have their own internal ratings that do not map to ANSI. Medeco uses a UL-437 certification for pick and drill resistance instead of focusing on ANSI grading. Mul-T-Lock has similar UL-437 listings. Abloy uses its own European grading system. For these high-security brands, the UL-437 listing is the equivalent of ANSI Grade 1 plus extra credit for pick resistance.
Common Las Vegas builder deadbolts
Most tract homes built in Vegas from 2000 forward came with Kwikset SmartKey or Schlage Plymouth-series builder hardware. Most of these are Grade 2 on the mechanical portion. The hardware itself is fine for residential. The factory-installed strike plate is the weak point on virtually every one. If you bought a Vegas tract home in the last 20 years, upgrading the strike plate is the highest-value $20 you will spend on home security.
Kwikset SmartKey gets some flak for having a documented bypass vulnerability on early-generation cylinders. Newer versions (post-2014) addressed most of it. For a primary entry, we lean toward Schlage B60 or B62 over Kwikset SmartKey, just for the better cylinder design. The price difference is small.

What about Nevada-specific requirements?
Nevada does not require a state-issued locksmith license, which makes verifiable insurance, bonding, and a documented service history especially important here. We carry general liability and bonding above industry minimums. There is no state requirement for a specific deadbolt grade on residential homes. Some insurance carriers in Nevada do offer a small discount for ANSI Grade 1 hardware (usually $10 to $30 a year off the homeowners premium). Worth asking your agent before the next renewal cycle.
Clark County building code requires deadbolts on all main entries for residential homes built after 1990. The code does not specify a grade, just that a deadbolt is present and operational. Most code-mandated installs are Grade 2 or Grade 3, often Grade 3 on builder spec. If your home was built before 1990 and never had the deadbolts upgraded, that is a low-hanging upgrade we do often on older Cheyenne corridor homes and 1970s ranches in the central Vegas neighborhoods.
Our recommendation, in one paragraph
Get a Schlage B60 Grade 2 deadbolt, a Schlage SG-300 reinforced strike kit, plus pay a locksmith $100 to $150 to install both with three-inch screws into the framing studs. Total cost about $160 to $250. That setup outperforms a Grade 1 lock with a builder strike in real-world kick-in resistance. If you want pick resistance on top (for a higher-value home), step up to a Medeco or Mul-T-Lock cylinder. For a primary single-family residence in a typical Vegas neighborhood, the Grade 2 plus reinforced strike combo is the highest-value upgrade we install.
Frequently asked
What does ANSI Grade 1 actually mean?
ANSI/BHMA Grade 1 is the toughest residential and light-commercial deadbolt rating defined by the American National Standards Institute and the Builders Hardware Manufacturers Association. To earn it, a deadbolt has to survive 250,000 cycles (turn open, turn close), 10 hammer strikes to the bolt face at 75 foot-pounds each, and a 360-pound static-load pull on the bolt. It is the rating used for commercial entries, government buildings, and high-end residential. For a Las Vegas house, Grade 1 on the front door is overkill for most homeowners but a sensible upgrade for the price difference.
What does ANSI Grade 2 mean?
Grade 2 is the middle tier. It has to survive 150,000 cycles, 5 hammer strikes at 75 foot-pounds, and a 250-pound static-load pull. It is the standard for most residential applications. Most builder-installed Schlage B60 and Kwikset 980 deadbolts in Las Vegas tract neighborhoods are Grade 2. For the average Summerlin or Green Valley front door, Grade 2 is enough as long as the strike plate is reinforced.
Is Grade 3 ever acceptable?
Grade 3 is the lowest rating, used on interior doors and low-priority entries. It survives 100,000 cycles, 2 hammer strikes at 75 foot-pounds, plus a 150-pound static-load pull. We do not install Grade 3 as a primary exterior lock on residential or commercial work in Vegas. If a builder installed Grade 3 on your back door or side gate, that is a quick upgrade we recommend at any rekey appointment. The cost difference between Grade 3 and Grade 2 hardware is around $15 to $25 per lock.
Will a Grade 1 deadbolt stop a kick-in?
The deadbolt itself, yes. The strike plate and the door jamb, probably not without reinforcement. The dirty secret of residential break-ins is that the deadbolt almost never fails. The strike plate screws pull out of the jamb wood, taking the strike with them. The deadbolt is still rigid and intact, just no longer engaged with anything. Grade 1 plus a reinforced strike plate (something like the Schlage SG-300 kit with three-inch screws into the stud) is what actually resists kick-ins. Grade 1 alone with the stock half-inch strike screws does not.
What grade do you recommend for a Las Vegas home?
For most homes in Summerlin, Green Valley, Centennial Hills, plus other Vegas tract neighborhoods, a Grade 2 deadbolt with a reinforced strike plate is the sweet spot. About $130 to $180 installed total. For higher-value homes in The Ridges, Anthem Country Club, or Red Rock Country Club, where contents and exposure warrant it, a Grade 1 deadbolt with high-security cylinder (Medeco or Mul-T-Lock) plus reinforced strike is the right answer. About $300 to $500 installed. For rental properties or back doors, Grade 2 alone is fine.
Are smart locks Grade 1 or Grade 2?
It varies by model. Schlage Encode and Schlage Connect are Grade 1 on the mechanical portion. Yale Assure Lock 2 and Kwikset Halo are Grade 2. August retrofits inherit the grade of whatever mechanical deadbolt is underneath (so install an August on top of a Grade 1 Schlage B60 and the system is Grade 1). The smart-lock electronics do not get rated by ANSI. Only the mechanical bolt-and-cylinder portion does. Read the spec sheet on any smart lock before assuming.
