The exact function depends on the type of tag.
Some devices are extremely simple. Others are electronic.
Barcode Tags
A barcode or QR-style tag may simply provide an identification number that employees can scan.
The number can correspond to a vehicle, key set, inventory record, or other information in the dealership’s system.
There’s no mystery here.
It’s essentially an electronic version of putting a label on a key.
RFID Tags:
RFID Tags
Some dealership key-management systems use RFID (radio-frequency identification) technology.
An RFID tag can communicate with a compatible reader over a relatively short distance.

This can make it possible for a key cabinet or other system to identify a particular key without requiring an employee to manually
type in information every time.
Bluetooth Tags
Some systems use Bluetooth-based technology to help locate keys within a limited area.
This can be particularly useful when a dealership has a large building, service department, parking structure, or vehicle lot.
Bluetooth-based systems are different from a dedicated GPS tracker. Their practical usefulness comes from operating within a nearby network or detection area rather than continuously reporting a vehicle’s location across the country.
Is It a GPS Tracker?
This is the question most people really want answered.
Don’t automatically assume that a small electronic tag is a GPS tracker.
A dealership key-control tag can be designed simply to identify or locate a key within the dealership’s own system.
GPS tracking is a different technology and typically requires a device capable of determining its geographic position and transmitting that information through an appropriate communication network.

attached to a key doesn’t automatically have those capabilities.
That said, the appearance of a device isn’t enough to identify its technology with certainty.
If you want to know exactly what is attached to your keys, the best source is the dealership that gave you the keys. Ask them what the tag is, what technology it uses, and whether it should have been removed before delivery.
Does It Track You After You Leave the Dealership?
For an ordinary dealership key-control tag, its intended purpose is generally inventory and key management, not monitoring a customer’s daily movements.
However, it’s worth avoiding an overly broad rule such as “these tags can never track anything outside the dealership.”
Different systems can have different capabilities.
For example, a Bluetooth-based system could potentially be detected by compatible equipment beyond the immediate key cabinet, while an RFID tag generally depends on a compatible reader. A barcode
contains identification information but doesn’t transmit a location at all.
So the safest answer is:
The tag’s presence alone doesn’t prove that your movements are being tracked.
If you’re concerned about a particular device, identify the manufacturer and model—or simply ask the dealership what it is.
Why Would the Dealer Forget to Remove It?
This is probably the least exciting explanation—and therefore one of the most likely.
Dealerships use key tags because they’re useful while the vehicle is part of their inventory.
Once you purchase the vehicle, the key is yours.
If the tag remains attached, someone may simply h
