What Is a Transponder Key?
AffinityX GrayTV • January 15, 2021
Almost all modern vehicles today are equipped with a radio transmitting device that lets the owner open the locks even from a few feet away. This device is called the "transponder key," which is also used by most car brands, like Ford, Toyota, Hyundai, Nissan, and Chevrolet. This blog summarizes everything you need to know about it, including its history and the benefits of having one.
Overview and History
The term "transponder" was coined in the 1940s and is a portmanteau of the words "transmitter" and "responder." Transponders, during that time, were used as communication devices operated by radars or radio frequency signals. But, for some reason, its popularity started to dwindle right after the war.
It was in the late 1980s to the early 1990s when transponders started gaining attraction again. They were used by vehicle manufacturers as a device that lets a person lock and unlock their car with the push of a button. This way, drivers no longer need to check whether each door is locked.
Today, transponder keys have other new features, so they can be used for other purposes aside from locking and unlocking their vehicles. There are also buttons in the fob that allow them to turn on their alarm systems along with other car features.
Main Benefit of Using Transponder Keys
Security is one of the main selling points of buying a car equipped with a transponder. This device is operated using a microchip hidden in the fob, which transmits signals to the receiver inside the car. A unique digital identification is used in the microchip, making it extremely difficult to bypass and providing a higher level of security compared to laser-cut keys of older vehicles.
Can Transponder Keys Be Replaced?
One problem with transponder keys is that they are very hard to replace. The embedded electronic features make it difficult for them to be manufactured using the old-fashion method of producing keys. That is why drivers who lose their transponder keys turn to a trusted auto locksmith in Illinois for professional assistance.
