Though the mysterious plastic tag attached to a new set of car keys can immediately spark questions about privacy and personal tracking, there is often a much simpler explanation. Dealerships handle large numbers of vehicles and keys every day, so small tags and labels may be used to identify, organize, and keep track of keys while cars are being moved around the lot or stored in different areas.

These tags can help dealership employees quickly match a key to a particular vehicle, especially when hundreds of cars are being processed, transported, cleaned, serviced, or prepared for customers. Sometimes, however, a tag that was intended for internal inventory control is accidentally left attached when the vehicle is handed over to its new owner, making it look like something much more mysterious than it actually is.

Unlike a GPS tracker, a basic inventory tag does not continuously transmit the vehicle’s location over long distances. Depending on the specific type of tag, it may simply contain a barcode, identification number, RFID component, or other information used within the dealership’s inventory system. Its purpose is generally organization rather than monitoring the person who receives the keys.

If you discover one attached to your new car keys, there is usually no reason to panic. It can generally be unclipped or removed once the dealership no longer needs it, and you can ask the dealer what the tag was used for if you are unsure.
