Lost your only car key? Before you order a replacement, check your owner's manual or look at the back of a working fob for the FCC ID. That 15-character code (like KOBGTX1) tells you the exact frequency and protocol. Also snap a clear photo of the blade part—some remotes need the uncut key too. Match both numbers with a dealer or online parts site, and you'll avoid buying a remote that won't sync with your car's receiver.
