Why Your 'High-Security' Lock Might Not Be Secure At All
Not all locks marketed as 'high-security' actually meet industry standards. We explain ANSI/BHMA ratings, bump-proof claims, and which brands actually deliver on their promises.
Walk into any hardware store and you'll find locks labeled "high-security," "maximum protection," or "pick-proof." But here's the uncomfortable truth: most of these locks don't meet any official security standards, and some provide barely more protection than a standard lock from 20 years ago.
After installing and servicing locks for 8 years across Maryland, we've seen the good, the bad, and the dangerously misleading. Here's what you need to know about lock security ratings and which products actually deliver on their promises.
The Marketing vs. Reality Problem
The Issue: The term "high-security" isn't legally regulated in the lock industry. Any manufacturer can slap it on their packaging without meeting specific standards.
What this means for you: That $40 "high-security" deadbolt from the hardware store might offer the same protection as a $20 basic lock—just with better marketing.
Understanding ANSI/BHMA Ratings
The only objective measure of lock security in North America is the ANSI/BHMA (American National Standards Institute / Builders Hardware Manufacturers Association) grading system.
Grade 1 (Highest Security)
Requirements:
Real-world meaning: These locks are designed for commercial applications but provide maximum residential security.
Cost: $80-250 for hardware
Brands that qualify: Schlage B600 series, Medeco, Mul-T-Lock, Kwikset SmartCode 914
Grade 2 (Mid-Level Security)
Requirements:
Real-world meaning: Adequate for most residential applications, significantly better than Grade 3.
Cost: $40-100
Brands that qualify: Schlage B500 series, Kwikset 980 series, certain Defiant models
Grade 3 (Basic Security)
Requirements:
Real-world meaning: The absolute minimum acceptable for residential use. Better than nothing, but not by much.
Cost: $20-50
Brands that qualify: Most budget hardware store locks
The "Bump-Proof" Myth
Lock bumping is a technique where a specially cut "bump key" is used to manipulate pin tumblers and open a lock in seconds. Videos of this circulate online, creating panic among homeowners.
Marketing Claims You'll See:
The Reality:
No pin tumbler lock is completely bump-proof. Some are significantly more resistant than others, but the term "bump-proof" is marketing hyperbole.
What Actually Resists Bumping:
Cost-Effective Bump Resistance:
If high-end locks are outside your budget, look for:
The "Pick-Proof" Deception
Lock picking is less common than bumping in real-world break-ins, but it's still marketed heavily.
The Truth About Pick Resistance:
Important Context:
Most break-ins DON'T involve lock picking. Criminals use:
1. Forced entry (kick the door)
2. Shimming the latch
3. Breaking a window
4. Unlocked doors/windows
Spending $300 on a pick-proof lock is pointless if your door frame can be kicked in or your window is easily accessible.
The Drill Resistance Factor
Drilling is how many locksmiths open locks when keys are lost. It's also how some burglars defeat locks.
What Makes Locks Drill-Resistant:
Truly Drill-Resistant Locks:
Budget Alternative:
Even Grade 2 ANSI locks have basic drill resistance that defeats casual attempts.
The Smart Lock Security Question
Smart locks introduce new security considerations:
Physical Security:
Most smart locks use standard pin tumbler mechanisms for backup keys, so they're only as secure as their mechanical components.
Digital Security:

Smart Locks to Avoid:
What Actually Makes a Lock "High-Security"
Real high-security locks have these features:
1. Restricted Keyways
Keys cannot be duplicated at standard hardware stores. You must go through authorized dealers with ID verification.
Why it matters: Someone can't copy your key without your knowledge.
Brands with restriction: Medeco, Mul-T-Lock, Abloy, Primus
2. Patent Protection
The key design is patented, preventing unauthorized duplication.
Check patent expiration: Many "restricted" keyways have expired patents, making them no longer secure.
3. Complex Mechanisms
Multiple security layers beyond standard pins:
4. Physical Reinforcement
5. Certification
How to Verify Lock Security Claims
Don't trust packaging alone. Here's how to verify:
1. Check for ANSI/BHMA Grade Label
It should be printed directly on the lock or in documentation. If it only says "meets ANSI standards" without specifying the grade, it's likely Grade 3.
2. Research the UL Rating
UL (Underwriters Laboratories) tests cylinder security. UL 437 is the most relevant standard.
3. Look Up the Brand
Research whether the manufacturer is known for security:
4. Check Independent Reviews
Look for reviews from locksmiths and security professionals, not just customer reviews.
5. Ask a Professional
A licensed locksmith can tell you immediately whether a lock meets professional security standards.
The Biggest Security Vulnerabilities (It's Not the Lock)
Here's what we find during security assessments:
1. Door Frame Strength
The problem: Amazing lock on a weak frame = worthless security
The solution:
2. Door Construction
The problem: Hollow core doors can be kicked through regardless of lock quality
The solution:
3. Exposed Hinges
The problem: Exterior hinges allow door removal without defeating the lock
The solution:
4. Window Access
The problem: Amazing door security, but ground-floor window 10 feet away
The solution:
5. Lock Installation
The problem: Even Grade 1 locks fail if improperly installed
The solution:

Installation Matters More Than You Think

Red Flags: Locks to Avoid
Marketing Red Flags:
Physical Red Flags:
Take Action: Assess Your Current Security
Quick Security Check:
1. Look for ANSI grade on your current locks (it's usually on the bolt mechanism)
2. Test your strike plate - Can you easily move it? Are screws short?
3. Check your door - Solid or hollow core? Kick it gently (really)
4. Examine hinges - Are pins accessible from outside?
5. Consider your entry points - All doors and accessible windows secured?
