Most offices know how many doors they have. Far fewer know how many keys exist, who holds them, and whether any were copied. Key control is the system that answers those questions: it decides who can have a key, how keys are copied, and how keys are tracked and returned. This article explains why it matters for an Ottawa business and how to set it up without much overhead.

The Problem With Uncontrolled Keys

Standard keys can usually be copied at any key-cutting counter in a few minutes. "Do Not Duplicate" stamped on the key doesn't stop that, because nothing ties the key to an authorization. Over time, keys are copied for convenience, lent to contractors or never returned by former staff. Each one is access you can no longer account for. When that happens, the only way to restore security is to rekey the affected locks, which costs time and money each time.

What a Key Control System Includes

1. Restricted keys

In a restricted-keyway system, key blanks aren't sold to the general public. New keys can only be cut by an authorized dealer, at the written request of the people you name. That closes the "copy it at the hardware store" gap. Restricted keyways are offered on many high-security lock systems.

2. A key structure that matches roles

A master key system lets individual keys open only the doors a person needs, while managers or maintenance carry a master. It reduces both the number of keys in circulation and the damage if one goes missing. See the master key system guide.

3. A key register

Keep a simple record, a spreadsheet or a dedicated tool, of:

  • each key's identifying number or stamp, and which doors it opens;
  • who holds it, when it was issued, and their signature;
  • when it was returned or reported lost.

4. Clear authorization rules

Decide who may request a new key or a copy. Usually one or two named people. Make sure the authorized dealer knows exactly who they are.

5. Secure storage for spare and master keys

Keep spares in a locked key cabinet, not in a desk drawer, and limit who can open it.

6. Regular audits

Once or twice a year, ask key holders to show their keys and compare them against the register. Investigate any gap promptly.

7. Offboarding

Make key return part of every departure, alongside deactivating cards, fobs and keypad codes. If a key isn't returned, decide right away whether the affected locks need rekeying.

Keys and Electronic Access Together

Card and fob access control makes it easy to revoke access and see who entered when. Many businesses use it for main entrances and keep mechanical keys for interior rooms, cabinets and as a backup. Key control still matters in a mixed system. A single uncontrolled master key can bypass an expensive electronic system.

Getting Started

Start with an audit of your current keys and doors. If the results are unclear, rekeying to a new restricted system with a fresh register gives you a clean baseline. To discuss key control for your business, see our master key systems service or call (613) 707-4884.
