2. Transponder Keys

Presented in the mid-1990s, these secrets feature a plastic head consisting of a little computer system chip. When the key is inserted into the ignition, the vehicle's engine control unit (ECU) sends out a signal to the chip. If the chip reflects the correct digital code, the car starts. If the chip is missing or configured improperly, the engine remains immobilized.

3. Integrated Key and Remote

This style integrates the RKE fob and the transponder key into one system. Often seen as “flip secrets” or “switchblade secrets,” these provide a compact solution but are more expensive to change since they require both mechanical cutting and electronic programming.

4. Smart Keys/ Proximity Fobs

As long as the fob remains in the motorist'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 expensive.
