What Is A Transponder Chip Key?

April 17, 2015 - 2 minutes read

To understand what a Transponder chip key, is we first need to decipher the meaning of the word ‘transponder’. The word transponder constitutes two words- ‘transmitter’ and ‘responder’. The device operates by working in tandem with an ‘interrogator’. The interrogator intends to inquire for information and transmits a radio wave signal at a particular frequency after receiving a signal transmitted at a different frequency. This dissimilarity in signal transmission allows a transponder to detect signals accurately. The main purpose of having a transponder chip in a car key is to ensure safety and security.

After inserting the key in the ignition, it makes contact with the car’s computer that confirms whether the right key has been inserted or not. In case a wrong key is turned in, the engine will not start.

The presence of transponder chips in car keys though helps in preventing cases of car theft, but in the event of misplaced keys this very blessing can become a nightmare as reprogramming of the key would be required to access the vehicle again.
