If you run a business, you've probably handed out more keys than you can count.

Then someone quits, or loses one, or never returns it and suddenly you're calling a locksmith, paying for rekeys, and playing detective to figure out who's still might be able to get in.

It's not just a hassle. It's a security risk.

That's where access control comes in. But what's the actual difference between a traditional key system and an access control system? And which one makes more sense for your business?

Let's break it down.

What is a key system?

A key system is exactly what it sounds like: metal keys and physical locks.

You've got:

Individual keys. Each person gets their own copy.

Master keys. Let you open multiple locks if needed.

Rekeys and copies. Every time someone leaves or loses a key, you either rekey the lock or take your chances.

It's simple. It works. But it's completely offline, and once a key is out there, you've got zero control.

What is access control?

Access control is a digital version of the same idea-just way smarter.

Instead of handing out metal keys, you give people access through:

Their smartphone

A fob or card
A secure link or passcode (in some cases)
And instead of physically rekeying doors, you manage everything from your phone or laptop.

With Nexkey, you can:

Grant or revoke access instantly
Set schedules (e.g., weekdays only, 9-5 only)
See who accessed which door and when
Lock or unlock doors remotely

It's access on your terms.

Side-by-side: Key Systems vs Access Control

Still think keys are "easier"?

We get it. If you only have one or two people with access and no turnover, keys might be "fine."

But as soon as you:

Hire part-time or seasonal staff
Share space with others
Have multiple locations
Need access logs for security

...keys stop being simple. They start becoming a liability.

In fact, we broke down exactly how expensive it is to keep using keys and it adds up fast.

Still using keypads or lockboxes?

You're halfway there. But those are still shared credentials. You don’t know who’s using them, when, or if they’ve been passed around.

Bottom line

Keys give people access.

Access control gives you control.

It's not just about unlocking doors. It's about knowing who's coming in, when, and why-and having the power to make changes in real time, without hardware headaches.
