Door Security
Access Hardware That Replaces Lost-Key Chaos
Credential readers, locking hardware, and controllers so you decide who enters, when they enter, and how quickly access is revoked.
Access control hardware turns a door into a managed checkpoint. Instead of chasing keys after every staff change, you issue credentials, set schedules, and pull reports of who came through. Readers and keypads sit at the entry; mag locks or electric strikes do the locking work; controllers tie it together with rules that match how your business actually operates.
Choosing hardware starts with the door itself—wood, hollow metal, glass storefront, or aluminum frame—and with life-safety requirements for egress. A rear warehouse door may need a different lock strategy than a main lobby. We also plan power supplies, battery backup, and cabling so the system does not fail the first time the building loses utility power for a few minutes.
For multi-unit residential and small commercial sites across Durham and Toronto, we often stage projects: secure the highest-risk doors first, then expand readers as tenants or departments grow. Clean installation includes labelled panels, documented credentials, and training so your team can add or remove users without calling us for every change—though we remain available when you need expansions or repairs.

FAQ
Questions about access control
Can access control work with my existing doors?
Most commercial and many residential doors can be fitted with strikes or mag locks. We assess frame, leaf, and egress needs before recommending hardware.
What happens if power fails?
Systems are designed with battery backup and fail-safe or fail-secure behaviour appropriate to the door and code requirements. We explain the choice for each opening.
Can I remove access for a former employee immediately?
Yes. Credentials can be deactivated in software without changing mechanical locks—one of the main reasons businesses move off keys alone.
Does access control integrate with cameras?
Often yes. Door events can be paired with nearby camera views so you can see who entered when reviewing an incident.
