Key Control for Property Managers — LockCRM Knowledge Base

A practical guide to key control — what it means, why it matters for multi-unit properties, and how digital systems protect your tenants and your liability.

What Is Key Control?

Key control is the practice of knowing, at any given time, who holds which keys to which locks. It encompasses the hardware (high-security cylinders, patented key blanks), the procedures (authorization forms, key receipts), and increasingly the software — digital systems that create a searchable, auditable record of every key issued or collected.

Why It Matters for Multi-Unit Properties

A residential property with 50 units might have hundreds of keys in circulation at any given time — master keys, unit keys, employee keys, contractor keys, and emergency keys. Without a formal system:

Former tenants may still possess working keys
Contractors may duplicate keys without authorization
You may not know if a key has been lost
In the event of a break-in, you can't prove which keys were outstanding

These gaps create real liability — both in terms of tenant safety and potential legal exposure.

Common gap: A tenant turnover triggers a rekey of unit locks — but the mailbox key, laundry room key, and garage fob are issued from a separate system (or no system at all). Key control covers the full picture.

The Bitting — The Core of Key Control

Every key has a bitting: the specific pattern of cuts on the blade. Two keys with the same bitting will open the same lock. This is why key control systems (including LockCRM) record bittings, not just key counts — it's the only way to detect conflicts, duplicates, or unauthorized copies.

How Digital Key Control Works

Modern locksmith software like LockCRM tracks bittings at the site level. When your locksmith rekeyes a unit, they enter the new bitting into the system. That bitting is:

Stored against the specific lock and unit
Checked for duplicates across all other locks at the site
Flagged if it conflicts with a master key progression
Recorded in a time-stamped audit log with the technician's name

What Property Managers Can See

Through the LockCRM client portal, property managers can:

View the full service history for each unit and site
Submit key copy requests digitally (with audit trail)
See any outstanding key copy requests and their approval status
Access invoices for all locksmith services

Implementing a Key Control Program

To build a strong key control program for your properties:

Conduct a Key Audit

Start with a full inventory of all outstanding keys per site. Your locksmith can help.

Establish an Upgrade Plan

Properties with many legacy keys may benefit from rekeying all cylinders to a new master system.

Set a Policy for Turnover

Every time a tenant leaves, a rekey should be standard — not optional.

Use a Digital System

Paper logs are better than nothing. A digital system with bitting records and audit logs is dramatically better than paper.

Train Your Staff

Everyone who touches keys — maintenance, leasing agents, management — should understand the key log and their obligations.
