Pick-resistant, drill-resistant, and nobody copies your key without your say-so.
High-security lock help
Most break-ins are brute force. But some doors warrant a lock that resists the skilled stuff too, including picking, bumping, drilling, and unauthorized key copying. High-security locks are built for exactly that. They use hardened components, complex keyways, and patented key control so a copy cannot be cut at the corner store.
For a pharmacy, a server room, a gun safe, or a homeowner who wants the best, they are worth the investment. Key control is often the biggest reason businesses upgrade: with a patented system, every copy goes through an authorized channel with your permission.
High-security locks earn the label through a combination of features that standard Grade 1 locks do not have. Complex pin designs with sidebars defeat common picking and bumping attacks. Hardened steel inserts destroy drill bits. Anti-drill pins spin freely instead of letting a bit grab.
UL 437 is the certification to look for on the highest-risk doors. It requires the lock to survive documented attack tests for a set period. Not every door needs a UL 437 cylinder, but if you are protecting controlled substances, cash, or server access, it is the right choice.
For many businesses and property managers, pick resistance is not the main reason to install high-security locks. Key control is. Standard keyways can be duplicated at any hardware store. A patented high-security keyway can only be duplicated by an authorized dealer with your permission.
We set you up as the controlling authority on the system. Future copies require authorization from you, not just the key. When an employee leaves, you know nobody walked out with a secret copy.
What we install
Not every door needs a UL-rated cylinder. We install and service proven patented systems including Medeco and Mul-T-Lock, matched to the door's actual risk level, so you are protected where it matters without over-investing everywhere else.

How it works
We match the hardware to what you are protecting, not to the highest price point. You are registered as the key control authority at install, so no copies can be made without your sign-off.
Tell us what the door protects and what concern you are solving, picking, copying, or forced entry.
We match the brand and security rating to the actual risk and quote it before we head out.
We install the lock and register you as the key control authority so future copies require your approval.
We hand you the keys, document the system, and explain how to authorize future copies.
Cost and options
High-security locks cost more than standard hardware because the engineering behind them costs more. A quality patented cylinder typically runs $150 to $350 per lock depending on brand and rating. Install adds labor on top.
The better question is what the door is protecting and whether the premium is worth it. We will give you an honest answer on that when you call. Not every door needs a UL 437 cylinder.
Final price confirmed before work starts. We recommend the right security level for the door, not the most expensive option.

FAQ
These answers cover what we hear most. A quick call is still the fastest way to confirm the details for your exact situation.
A high-security deadbolt with hardware and installation starts at $200, which is more than a standard deadbolt because the lock itself is built to a different standard and the keys are controlled. Rekeying an existing high-security cylinder starts at $45, and authorized key copies start at $30. We quote the full job on the phone first.
Yes. Plenty of our high-security installs are residential. Homeowners who want pick resistance and strict key control, so nobody copies a key without authorization, are a great fit. We will walk your doors and recommend where it is worth it and where a Grade 1 deadbolt is enough.
For most doors, a good Grade 1 deadbolt is plenty. High-security locks earn their cost on doors protecting real value or risk: pharmacies, server rooms, cash areas, or homeowners who want maximum protection and strict key control.
It means your keys cannot be copied at a hardware store. Patented high-security keys are only duplicated by authorized dealers with your permission, so no one makes a secret copy. For businesses, that is often the biggest reason to upgrade.
Drill-resistant, not indestructible. They use hardened steel inserts and anti-drill pins that defeat common drilling. Combined with pick and bump resistance, they raise the effort required far beyond what a typical intruder will attempt.
Proven patented systems like Medeco and Mul-T-Lock, among others. We match the security level and rating to the actual risk on each door.
