What's Transponder Key & How Did It Come About?
Transponder keys have been around for decades but how did they come about?
Car theft using hot-wiring technic was becoming common back in the 80’s. To combat this trend General Motors introduced chip keys in 1985 by adding a security feature to their key.
Transponder key (Chip Key) is a key equipped with RFID (radio frequency identification) chip inside its plastic head. This technique prevented car theft by rendering hot-wiring ineffective.
