Short answer: Car keys have evolved from simple metal blades to chipped and keyless systems. Knowing which type you have helps when you need a replacement.

Older vehicles use a plain metal key with no electronics. From roughly the mid-to-late 1990s onward, most cars adopted transponder keys, which carry a chip that talks to the immobilizer so the engine will only start with a recognized key. A transponder key must be both cut and programmed to work.
A remote head key combines the transponder key and the lock/unlock remote in one molded head. A flip key folds the metal blade into the fob, springing out at the press of a button. Both still rely on a chip for the immobilizer and a battery for the remote functions.
Smart keys, also called proximity keys, let you unlock and start the car while the fob stays in your pocket, using push-button ignition. They communicate wirelessly with the vehicle and require programming to pair. Because they are more complex, replacing a smart key is typically the most involved and costly key type.
