Benefits of High Security Locks | High Security Keys | High Security Brands
When standard locks aren’t enough, high-security locks are the answer. ACME Locksmith installs and repairs top-tier, high-security lock systems throughout Phoenix—the same kind trusted by banks, schools, medical offices, and government facilities.
We work with the strongest brands in the industry, including Medeco, ASSA Abloy, Marks, and Mul-T-Lock, giving your property serious protection against picking, bumping, and unauthorized key duplication.
What Are High-Security Locks?
High-security locks are built to resist the most common forms of break-in—including picking, bumping, drilling, and forced entry. They use advanced internal parts, like:
- Sidebars, ball bearings, and side pins
- Hardened anti-drill plates
- Heavy-duty Grade 1 materials
- Unique keyways that can’t be copied at a regular hardware store
These locks are extremely difficult to defeat, making them ideal for commercial doors, community gates, padlocks, and even residential doors in high-crime areas.
High-security locks offer superior protection with features such as extreme pick resistance, bump-proof key cylinders, and stronger materials. These locks provide top-tier security, and bypassing them is very difficult.
Where Can High-Security Locks Be Installed?
We can install high-security cylinders into:
- Standard door locks
- Padlocks
- Deadbolts
- Gate locks
- Mailbox locks
- Community access points

High-Security Keys
High-security keys protect you from unauthorized duplication. Unlike regular keys, they:
- Require special equipment to cut
- Can’t be copied at most locksmith shops
- Often include a physical key card that must be shown to get a duplicate made
This makes them perfect for employee key control, property managers, and anyone who wants to lock down access. If you want peace of mind, this is how you get it.
💡 Important: “Do Not Duplicate” keys offer zero real protection. DND keys are often copied at standard hardware stores without question.

You really can’t miss high-security keys. They’re like no other key you’ve seen. Look for:
- Dimples drilled into the key
- Side grooves that don’t go all the way through the key, but are milled down the middle or edge of the key
- A patent number stamped into the key—this usually means it’s protected

High Security Marks Key BlankAre High-Security Locks Worth the Money?
Yes—for most businesses high security locks are absolutely worth the money.
They eliminate your biggest weak points: easy-to-copy keys and locks that can be bumped or picked open in seconds.
For residential use, it depends. If your doors are solid and well-reinforced, upgrading to high-security locks can dramatically increase your home’s protection. If you’re not ready for a full upgrade, we can still improve your setup by installing a Grade 2 lock with a high-security cylinder. That gives you better security and key control, without going all-in on hardware.
Top Brands We Trust & Install
We only install high-security locks from manufacturers that have proven performance in tough environments.
Brands we work with include:
Mul-t-lock’s Bolt and Strike Join Together- Marks USA – Marks focuses on commercial locksets, for the most part, and they have both Grade 1 and Grade 2 available, as well as mortise, rim, and key-in-knob cylinders which can be used with other (select) manufacturer’s hardware such as Schlage. They offer products at a lower price point than some larger manufacturers.
- Mul-T-Lock – We admit it; this is our favorite high-security lock manufacturer. They also have cylinders available for retrofitting into a variety of lock brands. Their keys utilize a double dimple-cut keyway design (with a couple other keyway features designed to prevent bumping and picking). Their Hercular Deadbolt in particular features a retaining bearing that locks into the door frame, preventing the bolt from separating from the frame when locked. No other high-security lock has this feature.
- Medeco – Medeco uses a different method to achieve high-security, but their high-security cylinders are probably the most well known, being used in lots of government buildings. They, like Mul-T-Lock, offer many different types of locks featuring high-security cylinders. Their keyways, among other things, feature cross-cutting on the blade which makes bumping impossible./
- ASSA Abloy
