Transponder keys, remote keys, and smart fobs might look similar, but they work quite differently. A transponder key transmits a unique code when placed near a receiver, often used in cars with push-button start. Remote keys send radio signals to lock or unlock doors from a distance. Smart fobs combine both, storing digital credentials that communicate with readers for secure building or vehicle access. Understanding these differences helps you choose the right access solution.
