What We Repair

Service for Every Part of Your Entry System

Systems We Service

We Work on Many Systems We Didn't Install

We service and troubleshoot Brivo, DoorKing, Kantech, and UniFi Access systems, and many others after a quick review. If your system is one we aren’t certified or authorized to work on, we’ll tell you up front so you don’t waste time.

Emergency Access

Locked Out of Your Own Building?

If your system fails and people can’t get in or out, we restore access first so your business can keep running. Then we schedule the full repair as soon as possible.

Fast Answers

Many Fixes Don't Need a Site Visit

A fob that stopped working or a user who needs new access can often be fixed over the phone or remotely, so you’re back up and running faster.

Repair or Upgrade

Fix What Makes Sense, Upgrade What Doesn't

Not every problem means a new system. We’ll tell you honestly what can be repaired and what’s worth replacing. When an upgrade does make sense, we can phase it in, keeping the parts that still work and replacing the rest over time.

Managed Service

Catch Problems Before Your Team Does

With a managed security plan, we keep an eye on your system and often spot an offline panel before you notice it. Covered replacement parts mean a failed reader or camera doesn’t turn into a surprise hardware bill. You only pay for labor.

It depends on the age of the system, how often it fails, and whether parts are still available. We’ll give you an honest recommendation, and upgrades can be phased in over time.
