That odd plastic tag on your new car keys is almost certainly a dealership key tracking fob accidentally left on your ring. At the lot, tags pair each key set with a specific vehicle inside a locked cabinet so staff can see who took a key, when they took it, and where it is on the property.
Some systems use barcodes or RFID, others use short‑range Bluetooth to locate keys only inside the building or garage. They are not GPS trackers and do not follow you once you leave. You can safely unclip the tag; return an electronic fob to the dealer or toss a simple printed tag.
