Access Control & Keypad Entry

Access control is not a single product — it is an ecosystem of hardware and software working together. At the door itself, you will typically find one of three core locking mechanisms: an electric strike that releases the door frame latch when a valid credential is presented, a magnetic lock (magloc) that holds the door shut with electromagnetic force, or an access control mortise lock that combines a full-function mortise lock body with an integrated electronic reader. The mortise lock option is particularly well-suited to commercial doors in Columbia because mortise lock access control hardware is built to the same heavy-duty dimensions used in commercial door preps across South Carolina — no cutting new mortise pockets, no major door modification, and no unnecessary damage to your existing frame.

Beyond the lock mechanism, a complete system includes credential readers (keypads, proximity card readers, key fobs, or mobile-credential Bluetooth panels), a controller or panel that validates credentials against an access list, and a power supply with backup battery. Some installations also incorporate door position sensors, request-to-exit (REX) devices, and cloud-based management software so you can revoke or add credentials from any internet-connected device. Our technicians will assess your existing door prep, frame condition, and wiring situation before recommending the specific combination that serves your building without unnecessary complexity or expense.

The mortise lock is the workhorse of commercial door security, and it becomes even more powerful when paired with electronic access control. A standard commercial mortise lock houses the latchbolt, deadbolt, and auxiliary functions all in a single recessed steel case — far more robust than a cylindrical lock. When we upgrade a mortise lock to access control, we install an electrified trim on the outside (the keypad or card reader) that communicates with a controller to either energize or de-energize the lock based on the credential entered. For locations where rekeying is a recurring problem — think property management offices near Forest Acres or retail spaces with high employee turnover — this eliminates the key-cutting cycle entirely. A fob or PIN can be deleted in seconds from the management panel.

Electric strikes are a popular, cost-effective alternative when a full mortise lock access control upgrade is not necessary. The strike replaces only the door frame component; the existing lock mechanism on the door itself stays in place. When a valid credential is read, the strike's keeper pivots or retracts, allowing the latchbolt to pass through freely. This approach is commonly used on interior office doors, server rooms, and secondary entrances where traffic volume is moderate. Key fob systems layer neatly on top of either platform — each fob carries a unique encrypted ID, so you always know exactly which credential opened which door and when, which is invaluable for businesses required to maintain entry logs.

Every one of these services is performed by our mobile technicians who arrive in a fully stocked vehicle — there is no waiting for parts to be ordered or a second trip to complete the job. Our goal is always to work damage-free where possible, preserving your door and frame finish throughout the installation. If a situation does require any modification to the door prep, we discuss it with you first and explain exactly why it is necessary.

We do not publish flat-rate prices for access control projects because no two installations are identical, and quoting a number before seeing your door would not serve you honestly. The factors our technicians evaluate before confirming your exact up-front price include: the type of locking mechanism required (an access control mortise lock installation involves different labor and parts than an electric strike retrofit); the number of doors and credential readers in the project; whether existing wiring and conduit can be used or new runs are needed; the material and current condition of the door and frame; the credential technology you want (basic PIN keypad, proximity fob, mobile Bluetooth, or a multi-factor combination); and the time of day or urgency of the request — our 24/7 availability means we respond to after-hours and weekend emergencies, and that availability is reflected in the pricing structure. We confirm your complete, itemized quote before any work begins, so there are no surprises on the invoice. If your situation has changed by the time we arrive on site, we communicate any adjustment immediately and only proceed with your approval.

For businesses evaluating access control system installation for the first time, the conversation often starts with a straightforward question: which doors actually need electronic control? Our experienced technicians help you prioritize — main entry, server room, and cash office doors are typically the highest-value targets — so you can phase the project in a way that fits your operational timeline. Ready to get a clear picture of what your project involves? Call (631) 380-4138 — we answer 24/7 and can dispatch a qualified technician to your Columbia location for a no-pressure on-site assessment.
