Introduced in the mid-1990s, transponder keys consist of a little microchip in the plastic head of the key. When the key is inserted into the ignition, the car’s engine control unit (ECU) sends a signal to the chip. If the chip does not respond with the right digital code, the car will not start.

3. Key Fobs and Remote Heads

These keys integrate a mechanical blade with a push-button control unit that enables the chauffeur to lock and open doors or set off an alarm. Oftentimes, the “remote” and the “key” are different, however in “remote head” secrets, they are incorporated into a single unit.

4. Smart Keys and Proximity Fobs
