A standard commercial lock stops honest people. A high-security lock stops determined ones.
New Jersey Locksmith Guidance
Precision-tolerance pin chambers and sidebar mechanisms that defeat standard picking tools used by intruders.
Hardened steel inserts and anti-drill plates that protect the cylinder and bolt from power tools.
Proprietary key blanks that cannot be duplicated at hardware stores, so only authorized copies can be made.
ANSI/BHMA Grade 1 hardware rated for the highest duty cycle and impact resistance available in commercial locksets.
The word “commercial” on a lockset label does not mean much on its own. Grade 3 commercial locks are not much stronger than residential hardware. Grade 1 commercial hardware is a significant step up, but even within Grade 1 there is a range from basic to genuinely attack-resistant.
The difference at the high end comes down to a few specific features.
Picking resistance starts with pin tolerance. Standard locks have enough play between the pin stacks and the cylinder bore that a skilled person can set pins one at a time with a tension wrench and pick. High-security cylinders are manufactured to tighter tolerances, and they add secondary mechanisms like sidebars: an additional blocking component that cannot be manipulated with standard pick tools.
Bump resistance matters because bumping is fast and quiet. A bump key can open a standard pin tumbler cylinder in under ten seconds. High-security cylinders use alternative pin designs, like serrated or spool pins, that make bumping ineffective.
Drill resistance protects the cylinder from power tools. Hardened steel inserts sit around the cylinder core. A standard drill bit hits the insert, skips, and cannot make progress. Some cylinders also include carbide or glass inserts that shatter drill bits on contact.
We do not recommend a blanket upgrade when a targeted fix is the right answer. You get an honest assessment of exactly which doors need attention.
Key control is as important as the physical lock. A standard commercial key blank is available from thousands of hardware stores and key duplication kiosks. An employee who wants a copy of your master key can get one made without your knowledge in under five minutes.
Restricted keyway systems use key blanks that are patented or otherwise controlled. They are only available through authorized dealers, which we are for several restricted keyway lines. When we sell you keys as part of a high-security installation, those keys are documented. Every copy we cut is logged. You know exactly how many keys exist.
For businesses where key control matters, such as pharmacies, financial offices, law firms, and medical practices, this is not a premium feature. It is the baseline.
Every key we cut is logged. You know exactly how many copies exist and who holds each one.
Not every business needs the highest available security grade. The right answer depends on what you are protecting, your threat profile, and your budget.
We start with a conversation. What are you protecting? What has happened before, either at your location or in your area? What are the entry points? We look at your doors, your frames, and your existing hardware before we recommend anything.
If your door frames are weak, a high-security cylinder will not help much: a kick-in bypasses the lock entirely. We look at the whole picture. Sometimes the right answer is a high-security cylinder plus a door reinforcement kit. Sometimes it is just the cylinder. We tell you which.
Request a locksmith. We are available 24 hours a day, every day, across all 21 NJ counties.
Locksmith Questions Answered
High-security cylinder replacement on an existing commercial door runs $200 to $500 per door depending on the brand and cylinder type. Full mortise lock replacement with a high-security grade 1 unit runs $350 to $800 per door including hardware and labor. We quote the full price before any work is scheduled.
No. There are concrete differences. High-security locks use tighter tolerances between pins and the cylinder bore, making picking much harder. They include sidebar or secondary locking mechanisms that standard picks cannot defeat. They use drill-resistant materials around the cylinder. And they are often paired with restricted keyways that prevent unauthorized key duplication. These are measurable, testable differences.
We install and service Medeco, Mul-T-Lock, ASSA Abloy, Schlage B-series Grade 1, and other high-security commercial lines. If you have a specific brand requirement, tell us when you call.
Often yes. Many commercial doors use interchangeable core or removable core systems where the cylinder can be upgraded without replacing the lockset body. We assess your existing hardware and tell you whether a cylinder swap is possible and what it costs.
No. High-security locks operate exactly like standard locks from the user's side. The added security is inside the mechanism, not in how the key feels to use.
Call us. We assess the doors that were targeted, look at what method was attempted, and recommend the specific upgrade that addresses that attack vector. We do not recommend a blanket upgrade if a targeted fix is the right answer.
