Mechanical Era (Pre-1995) Cut metal just Low No Transponder Era (Late 90s-- 2000s) RFID chips embedded in plastic head Moderate Yes Remote/Fob Era (2000s-- Present) Radio frequency transmitters + transponders High Yes Smart Key/ Proximity Era (Modern) Encrypted rolling codes + push-to-start Very High Yes (Advanced diagnostic tools)Today's automobiles utilize electronic handshakes. When a driver tries to begin the vehicle, the automobile's computer system sends a radio frequency. The key needs to react with the correct digital signature.
