Who Still Has Keys to Your Business or Home? | Key Control & Rekeying Tips

If you don’t know who has a key—it's time to find out. Untracked access is one of the most common gaps in physical security.

Before you head into the weekend, here’s something worth thinking about:

Who still has keys to your business… or your home?

It’s one of those small details that gets forgotten — until something goes wrong.

Think about it:

• Did a staff member quit last month?

• Did a contractor wrap up a reno and keep a spare?

• Do your in-laws, exes, or former tenants still have access?

  
  

We’ve all handed out keys with good intentions. But unless you’ve had the locks rekeyed, those keys still work — and that’s a gap worth closing.

Something to think about before Monday:

🔐 Who actually needs access today?🔑Are your locks still running on the same keys from five (or ten) years ago?🏢Are there any untracked spares floating around — “just in case”?

Here’s what I recommend:

You don’t always need to change hardware. Most of the time, a simple rekey is all it takes to ensure your old keys no longer work.

If you’re looking to tighten things up, restricted key systems are the next step. Unlike a “Do Not Duplicate” stamp (which only works if the person cutting the key follows the rules), these systems are controlled. Keys are only available through authorized locksmiths, and every copy requires a signed letter of authorization. Those letters can be used to help track how many keys are in circulation. 

And if security is a major concern — especially for storefronts, sensitive areas, or external access points — high-security key systems like those offered by Medeco or Mul-T-Lock add serious physical protection. Their cylinders are engineered to resist picking and drilling, and they pair perfectly with alarms, access control, and other internal systems.

That’s what I mean when I say layered security:Your keys control access.Your electronics provide visibility.Your educated team backs it all up.

Whether it’s your business, your building, or your rental —it’s worth asking:
