Access Control vs Traditional Keys: Why Southeast Michigan Businesses Are Upgrading

Keys are simple—until they aren’t.

For many businesses across Southeast Michigan—whether in Ann Arbor, Detroit, Ypsilanti, Brighton, Novi, Saline, or West Bloomfield—traditional keys eventually create the same problems:

  • You don’t know who has copies

  • You can’t revoke access instantly

  • Lost keys become a security event

  • Managing vendors and turnover is a headache

That’s why more local businesses are moving to modern access control—systems that replace keys with key fobs, cards, mobile credentials, and centralized management.

Here’s what to know before you upgrade.

1) Keys Don’t Scale With Your Business

Keys work fine when you have:

  • A small staff

  • One location

  • Low turnover

But as soon as you add:

  • More employees

  • More doors

  • Multiple sites

  • Vendors and contractors

…key management becomes uncontrolled. Access control solves this by letting you assign permissions by role, time, and location—without rekeying doors every time something changes.

2) Instant Access Changes = Better Security

With keys, removing access usually means:

  • Chasing down a key

  • Hoping there aren’t copies

  • Rekeying hardware (and still guessing who has access)

With access control, you can:

  • Disable a lost credential instantly

  • Remove access when someone leaves

  • Create temporary vendor access

  • Lock down a door during an incident

That “instant control” is one of the biggest reasons businesses upgrade.

3) You Get an Audit Trail (Keys Can’t Do That)

If something goes missing and you only use keys, you’re left with assumptions.

Access control systems can provide:

  • Door event history (who accessed, when)

  • Scheduled access (who should have access at what times)

  • Alerts for propped doors or forced entries (depending on setup)

When paired with security cameras, access events can be matched to video so you can confirm what happened in seconds—not hours.

4) Fobs, Cards, or Mobile Access? Here’s the Practical Difference

Most businesses choose one of these:

  • Key fobs/cards: Simple, durable, easy to issue

  • Mobile credentials: Great for managers, multi-site orgs, and reducing “forgotten fob” issues

  • Mixed approach: Common—mobile for leadership, fobs for staff

The right option depends on your operations, turnover, and how you want to manage users.

5) The Doors That Usually Make the Biggest Difference

Most Southeast Michigan businesses don’t need every single door converted on day one.

The best “first doors” are usually:

  • Main employee entrance

  • Rear/warehouse entrance

  • IT/server/network closets

  • Offices with sensitive materials

  • Receiving/shipping doors

A smart rollout starts with the doors that reduce risk immediately.

6) Local Installation and Support Matter

Access control is not just hardware—it’s how the system is designed, installed, and supported.

A good install includes:

  • Clean, labeled wiring

  • Reliable power and backups (when required)

  • Door hardware compatibility checks

  • Clear user management setup

  • Documentation for your team

Local support matters when you need changes fast—especially for staffing changes, vendor access, or operational updates.
