When I started Arch City Locksmith, I met business owners who used metal keys. These keys had changed hands so much that no one knew who had access. Keys were copied, lost, or kept in drawers. As a result, doors that should have been secure were not.
Commercial keypad locks solve problems that come with traditional key systems. They replace shared keys with secure access codes. This way, you always know who can enter a specific area. This is especially helpful in places like offices, retail stores, warehouses, or professional buildings. Keypad locks make access control easier and simplify management tasks. You can easily change access codes when needed. This helps improve security and gives you better control over who enters restricted areas. In the end, these locks provide more confidence, knowing that only authorized people can enter sensitive locations.
I specialize in the installation of advanced keypad systems tailored for businesses throughout the vibrant regions of St. Charles, St. Peters, O’Fallon, Wentzville, Weldon Spring, Cottleville, Bridgeton, Maryland Heights, and the surrounding areas of St. Charles County. My goal is to enhance security and accessibility for businesses in these communities.

Commercial High-Security Lock Installation,
Commercial Rekeying Services, and
Commercial Safe Installation to create a complete, modern access control structure for your business.
A keypad lock solves the problems of shared keys. You no longer have to worry about who has a copy. Instead, you control access with a code. This code can be changed or removed easily without rekeying locks or replacing hardware.
Businesses often choose keypad locks because they offer:
Only people with valid codes can enter. You decide who gets which code.
Employees do not pass keys around. Managers do not need to track down copies.
Staff can be grouped by job role, with different codes for different areas.
Businesses can manage access without changing hardware every time staff changes.
Most keypad systems work well with:
I focus on installing advanced keypad systems on many types of commercial doors. This helps improve security and access control in different places. Here are some key locations where I set up these systems:
In many commercial buildings, keypad locks work with strong mechanical high-security locks on outside doors. This combination offers strong security outside while allowing controlled access inside. For multi-tenant buildings, keypad systems are very useful. They help property managers manage access easily without giving out new keys all the time. This makes operations smoother and improves security for everyone.
Every business has different needs, so I install a range of keypad lock types including:
Great for small to mid-sized businesses that want simple code-based entry without network integration.
Ideal for interior offices, employee entrances, and supply rooms.
Combines keypad convenience with commercial high-security cylinders for master key control.
Perfect for storefronts, warehouses, and commercial buildings that require exit devices by code.
Best for businesses planning to scale their security system.
If you want help choosing the right hardware, I walk you through the options, show the differences, and match the hardware to your type of business and door construction.
A keypad lock is only as good as the installation. My process ensures the hardware works the way your business needs it to.
I evaluate your door, frame, hinges, hardware, and how staff move through the space.
This helps me place the keypad where it makes the most sense.
Once we confirm the door design and goals, I recommend the keypad model that fits your needs whether it's a standalone unit, a keypad for a panic bar, or a unit that supports high-security cylinders.
Commercial doors are not all the same. I adjust and prepare the door as needed, mount the keypad hardware, secure the lock body, and ensure all mechanical parts operate smoothly.
I set up your initial access codes, including:
I show you how to add, remove, or update codes so you can control access without calling a locksmith every time.
This installation often pairs perfectly with Commercial Rekeying Services when you want to clean up old keys while improving day-to-day access control.
Many businesses choose to use keypad entry systems along with a master key system. This combination offers several benefits:
If your organization already has a master key system, I can easily add keypad locks to it. If you don’t have a master key system, we can work together to create one during the installation, tailored to your needs.
Keypad locks excel at access control, but exterior doors often still require stronger physical protection.
That’s where Commercial High-Security Lock Installation comes in.
I often install keypad locks on interior doors and use high-security cylinders on exterior entrances to give businesses strength on the perimeter and flexibility inside.
Businesses typically find themselves in need of an upgrade to a keypad system under several circumstances. One common reason is when too many employees possess copies of physical keys, which can lead to security vulnerabilities. Additionally, if keys have been lost or not returned by former employees, this can create significant risks for your business. Frequent staff turnover can also necessitate rekeying, making it a cumbersome and costly process that only authorized personnel can enter sensitive locations.
Moreover, if you desire enhanced control over who has access to restricted areas within your premises, a keypad system can provide that level of security. As your business expands, organized access control becomes increasingly important to ensure that only authorized personnel can enter sensitive locations.
Furthermore, if you are looking for a keyless entry solution that seamlessly integrates with your existing commercial hardware, a keypad system is an excellent choice. If you’re already in the process of upgrading your locks, rekeying, or installing a safe, incorporating a keypad system can significantly enhance your business’s security, making it more efficient and easier to manage overall.
Many business owners wonder what professional deadbolt installation actually involves. The process is more thorough than simply drilling a hole and dropping in a lock cylinder. A qualified locksmith follows a structured sequence to ensure the hardware seats correctly, the bolt extends fully, and the strike plate holds under real pressure. Here is how Arch City Locksmith approaches every commercial installation.
Before any hardware is touched, the technician evaluates the door material (wood, hollow metal, aluminum), frame construction, and existing bore holes. This determines the correct backset, bolt throw length, and any reinforcement needed. A door that is warped, cracked, or improperly aligned will undermine even the strongest deadbolt, so this step guides every decision that follows.
Using the assessment findings, the locksmith selects the appropriate deadbolt model from professional-grade manufacturers. Door thickness, bore diameter, and the intended security level all factor into the choice. For businesses pairing the deadbolt with a commercial keypad or smart lock system, compatibility with electronic components is verified at this stage as well.
If a new bore is required, a hole saw sized to the lock body is used to create a clean, centered opening. The deadbolt cylinder and tailpiece are then seated and tested for smooth rotation before the face plate is secured. Precise boring prevents binding, which is one of the most common causes of premature lock wear in commercial settings.
A deadbolt is only as strong as its strike plate mounting. Standard builder-grade strike plates often use short screws that anchor into door casing rather than the structural frame. Our installations use heavy-duty strike plates secured with 3-inch screws that reach into the door frame stud, significantly increasing resistance to kick-in attempts. For metal doors, we use appropriate anchors for the substrate.
Once the hardware is mounted, the technician cycles the bolt repeatedly to confirm smooth throw and retraction. The door is closed and relocked several times from both interior and exterior sides. Any minor adjustments to the strike box or bolt height are made before the job is considered complete. You receive a full walkthrough of how the lock operates and what to watch for over time.
Not every deadbolt works on every door. Commercial properties use a wide range of door constructions, from solid wood to hollow-core steel, aluminum storefront frames, and glass-panel entries. Selecting hardware without accounting for door type, thickness, and daily traffic volume is one of the most common mistakes made in commercial security upgrades. Here are the key factors that guide our hardware recommendations.
Standard commercial doors run 1-3/4 inches thick, but some specialty doors differ. Backset, the distance from the door edge to the center of the bore hole, must match the lock body. Mismatched backsets cause binding and reduce the effective bolt throw, weakening the overall installation.
Hollow metal, solid wood, aluminum, and fiberglass doors each require different drilling techniques and anchor hardware. A lock installed correctly on a wood door may need a completely different approach on a hollow-metal frame common in warehouses and industrial facilities across Wentzville and O’Fallon.
Commercial-grade deadbolts from reputable manufacturers include hardened steel inserts, security pins, and anti-rotation collars not found on residential hardware. For higher-risk entry points, we recommend cylinders that carry high-security lock ratings with pick-resistance certifications.
For businesses managing multiple staff members, restricted keyway systems prevent unauthorized key duplication. Unlike standard hardware store keys, restricted keyways can only be cut by authorized locksmiths, giving you a documented chain of custody for every key issued.
A standard deadbolt throws one inch. For commercial applications with heavier doors or higher traffic, a 1-1/2 inch throw provides greater engagement with the frame and improves resistance to forced entry. This is particularly important for main entrances that see constant daily use.
Deadbolts frequently need to coexist with commercial door closers, panic bars, and access control systems. We verify that the chosen lock body does not conflict with existing hardware mounting positions, avoiding costly rework after installation.
One of the most common questions property managers and business owners ask is whether they need a full lock replacement or whether rekeying the existing hardware is sufficient. Both are legitimate options, and the right choice depends on the condition of the lock, the circumstances that professionaled the review, and your long-term security goals.
Rekeying changes the internal pin configuration so old keys no longer work. It does not change the physical lock body, meaning existing vulnerabilities in the hardware remain if any are present.
If you are unsure which route makes sense for your property, our locksmiths can evaluate the existing hardware and give you an honest recommendation. There is no obligation to upgrade if rekeying accomplishes your security goal. You can also review our commercial deadbolt repair and replacement service for situations where existing locks need assessment before a full decision is made.
Commercial deadbolt installation is not just a security decision. Depending on your business type, industry, and location, the hardware on your doors may have implications for building code compliance, insurance coverage, and liability. Understanding these factors before a break-in or audit is far better than learning about them after an incident.
The International Building Code, which Missouri adopts with local amendments, includes requirements for door hardware on certain commercial occupancy types. Businesses in healthcare, education, and assembly occupancies often have specific locking requirements tied to fire egress regulations. Properly installed deadbolts must not interfere with emergency exit hardware on designated egress routes. Our team is familiar with these requirements and installs hardware accordingly.
Commercial property insurance policies frequently include language about the type and grade of locks required on covered premises. Some insurers mandate ANSI Grade 1 deadbolts on all exterior entry points, and failure to comply can affect your ability to file a claim after a break-in. Before upgrading, it is worth reviewing your policy language or asking your insurer directly about lock rating requirements.
The American National Standards Institute and the Builders Hardware Manufacturers Association grade commercial door hardware on a three-tier scale. Grade 1 is the highest rating and is designed for demanding commercial applications. Grade 2 suits lighter commercial use, and Grade 3 is residential. Arch City Locksmith installs Grade 1 hardware across all primary commercial entry points for maximum durability and compliance support.
The Americans with Disabilities Act requires that hardware on accessible entry points be operable without tight grasping, pinching, or twisting of the wrist. Standard keyed deadbolts alone may not satisfy this requirement on primary accessible entrances. In those cases, a combination of a keypad or smart lock paired with a deadbolt, or a lever-operated exit device, may be the appropriate solution.
Any door on a required means of egress cannot be fitted with a lock that requires a key or special knowledge to open from the inside during an emergency. Double-cylinder deadbolts, which require a key on both sides, are restricted on fire exit routes under NFPA 101. Our team ensures that double-cylinder locks are only placed on appropriate doors and that all exit routes remain compliant with commercial panic bar and exit device standards.
Businesses in healthcare, finance, and legal services may be subject to data protection standards that include physical security requirements for server rooms, records storage, and office areas. Installing commercial high-security locks on restricted areas is a practical way to document physical access controls as part of a broader compliance program.
