What Is the Strange Device Attached to My New Car Keys?

You finally get the keys to your new car, walk outside, and notice something odd.

There's a little plastic tag—or maybe a small electronic-looking device—attached to the keyring.

Wait… what is that?

If you're wondering whether the dealership accidentally left some kind of tracking device on your keys, you're certainly not the first person to have that thought!

In many cases, that little tag is simply part of the dealership's key-control or inventory system. Dealerships may handle hundreds of vehicles and countless sets of keys, so organized key-management systems can make it much easier for employees to identify, locate, and control them.

But here's the important part: not every tag is necessarily the same.

Depending on the dealership and the device, it could be a simple barcode or QR label, an RFID tag, a Bluetooth-enabled tracker, or another type of inventory-control device.

So before you pull it off and toss it in the trash, let's take a closer look at that mysterious little gadget!

Why Do Dealerships Put Tags on Car Keys?

Imagine working at a busy dealership with hundreds—or potentially thousands—of vehicles.

There are:

  • New vehicles
  • Used vehicles
  • Trade-ins
  • Cars waiting for service
  • Customer vehicles
  • Loaner vehicles
  • Test-drive vehicles
  • Vehicles parked in different sections of the lot

And nearly every vehicle has one or more sets of keys.

Now imagine trying to find one particular set of keys without an organized system.

It could become a nightmare.

That's why dealerships may use electronic key-management systems.

A key can be assigned an identification tag that corresponds with information in the dealership's inventory or key-control system. When an employee takes a key, returns it, or moves it to another location, the system may help staff keep track of what happened.

Instead of five employees wandering around the lot asking, "Has anyone seen the keys for that SUV?", there's a system designed to make the process much more organized.

And honestly, when you're juggling that many cars and keys, a little organization goes a long way!

What Does the Little Tag Actually Do?

The exact function depends on the type of tag attached to your keys.

Some are incredibly simple. Others contain electronic components.
