2. Transponder Keys
Presented in the mid-1990s, these keys feature a plastic head including a small computer chip. When the key is inserted into the ignition, the automobile's engine control system (ECU) sends a signal to the chip. If the chip shows the proper digital code, the car starts. If the chip is missing or configured incorrectly, the engine remains paralyzed.
3. Integrated Key and Remote
This design combines the RKE fob and the transponder key into one system. Often seen as "flip secrets" or "switchblade secrets," these offer a compact solution but are more expensive to change because they need both mechanical cutting and electronic programs.
4. Smart Keys/ Proximity Fobs
The most sophisticated variation offered today, clever keys utilize distance sensing units to communicate with the car. As long as the fob remains in the chauffeur's pocket or bag, the doors unlock automatically, and the engine begins with a "Push to Start" button. These replacements are the most technical and costly.
