At A Complete Lock And Key Service, we understand that commercial locksmithing and security is not just about locks—it’s about control, safety, and continuity. Whether you manage a retail storefront in North County, a corporate office in downtown St. Louis, or an industrial warehouse, your physical security infrastructure is the first line of defense against theft and unauthorized access.
As a fully licensed and bonded commercial locksmith, we provide comprehensive security solutions tailored to the unique needs of St. Louis businesses. From high-security lock installation to complex access control systems, our certified technicians deliver precision workmanship that meets local fire codes and ADA compliance standards.
Advanced Access Control Systems & Keyless Entry
Modern businesses require more than a brass key to stay secure. We specialize in the installation and maintenance of state-of-the-art access control systems that give you total oversight of who enters your building and when.
Magnetic Locks (Maglocks): We install fail-safe electromagnetic locks ideal for high-traffic glass doors and main entrances, ensuring seamless integration with your intercom or keypad systems.
Electric Strikes & Keypads: Upgrade your standard door hardware with electric strikes that allow for remote buzzing-in of visitors or PIN-code entry for employees.
Biometric & Smart Locks: Eliminate the risk of lost keys entirely with fingerprint scanners and Bluetooth-enabled smart locks for sensitive areas like server rooms or executive offices.
Master Key Systems & Restricted Keyways
One of the biggest vulnerabilities in commercial security is unauthorized key duplication. If an employee lends a key to a friend or loses one, your entire building could be compromised.
Custom Master Key Set Design
We design and implement hierarchical master key systems that allow business owners and facility managers to open every door with a single Grand Master Key, while restricting employees to specific zones.
Grand Master Keys: Total access for owners.
Sub-Master Keys: For department managers.
Change Keys: For individual employee offices.
High-Security Cylinders & Restricted Keys
We utilize restricted keyways (such as Medeco, Mul-T-Lock, or Primus) where keys cannot be duplicated at a hardware store. Copies can only be made by authorized personnel at A Complete Lock And Key Service, giving you an audit trail and peace of mind.
Commercial Door Hardware & Life Safety Devices
Your locking hardware must do double duty: keeping intruders out while ensuring safe egress for occupants during an emergency. We supply and install heavy-duty hardware grade 1 and grade 2 for maximum durability.
Exit Door Locks & Panic Bars: We install and repair panic devices (push bars) that ensure compliance with St. Louis fire safety regulations, allowing for immediate, unhindered exit.
Door Closers: Ensure your fire doors latch automatically and securely every time with properly adjusted hydraulic door closers.
Mortise Locks & Rim Cylinders: We service and replace complex commercial mortise bodies and rim cylinders found in aluminum storefront doors.

The Local Locksmiths For Businesses
You Need Highly Trained Locksmiths For Your Company
When it comes to the locks, keys, and security at your business, you need highly-trained locksmiths, with years of training and expertise. Our business locksmiths have over 40 years experience keeping business owners, their customers and employees, and products- locked up and safe. From access control systems to safes and high security locks- we have the technology, tools, and knowhow to get the job done.
Professional Safe Services: Damage-Free Opening
When you are locked out of your commercial safe, you need immediate access without destroying your investment. Unlike general handymen who might drill blindly, we use precision manipulation and dialing diagnostics.
Damage-Free Safe Cracking: Our experts use stethoscopes, scopes, and advanced manipulation techniques to open safes without structural damage whenever possible.
Safe Combination Changes: protecting your assets after staff turnover by resetting your mechanical or digital safe lock combination.
Bolt Down & Installation: We secure floor and wall safes to prevent physical removal of the unit.
Commercial Rekeying & Lock Replacement
Employee turnover is a reality of business. When key-holding staff leave, or if you acquire a new property, you must ensure previous keys no longer work.
Commercial Rekeying: A cost-effective alternative to hardware replacement. We change the internal pins of your existing IC Cores (Interchangeable Cores) or standard cylinders so old keys become useless.
High-Security Lock Upgrades: Replace vulnerable standard locks with drill-resistant and pick-resistant high-security cylinders.
File Cabinet & Desk Locks: Don’t neglect internal security. We replace and rekey locks for file cabinets, desks, and mailboxes to secure sensitive documents.

People Often Ask us
The cost varies based on the number of lock cylinders and the type of hardware (e.g., standard vs. high-security IC cores). Rekeying is significantly cheaper than replacing all hardware. Call us at (314) 423-3720 for a custom quote based on your facility size.
Yes. Our goal is always damage-free safe opening via lock manipulation. However, in cases of mechanical failure, precision drilling may be required, after which we professionally repair the safe to factory standards.
Absolutely. We specialize in magnetic locks (maglocks) and glass door patch fittings, often pairing them with motion sensors and “Request to Exit” buttons for a complete access control solution.
A master key opens multiple different locks. A restricted key is a key blank that is patent-protected and cannot be duplicated without authorization. The most secure systems use both master keying and restricted keyways.
