What is a Transponder?
A Transponder is a device that transmits and receives data using radio frequency. Although it is relatively new to the automotive industry, transponders are widely used in automated toll booths, animal tracking, and access control security systems to name a few. Basically, a transponder key is a key with a built-in electronic identification tag.
How do Transponder keys work?
Embedded in the head of each key is a transponder chip, which contains one of a trillion possible electronic codes. When the key is inserted into the ignition, the transponder sends a signal to a disc-shaped antenna surrounding the cylinder housing behind the shroud on the steering column. The antenna relays the signal to the control module and if the signal is recognized, the vehicle is allowed to start.
The transponder key was first introduced around 1995, and now are standard in most vehicles.
