What Is A Transponder (Chip) Car Key?

9/6/2015

6 Comments

 
A transponder key is a key with an encrypted chip embedded in its' plastic head, which communicates to the vehicle that it is an authentic key, allowing the car to be started. Most cars and trucks built 1998 and newer are equipped with an immobilizer and transponder keys. When you turn the key in the ignition, the key is checked by the receiver unit- if the receiver verifies that the key sends the correct information, then the car will start. If the receiver doesn't recognize the code sent by the key, then the car will be unable to start.

Why Do Cars Use "Chip" Keys?

This technology was developed as a response to the vulnerabilities of old style car security, which consisted solely of an ignition lock. Criminals were able to hotwire cars, break the ignition lock, or even use shaved keys to bypass the lock cylinder- and steal the car. The use of immobilizer technology has greatly improved a cars' security level, making it exponentially more difficult to steal a car. According to data from the Federal Bureau of Investigation, in 2013, car thefts in the US were at their lowest levels since 1967. This major decrease in thefts can be attributed mainly to transponder technology in cars and trucks. It is said that transponder technology was a joint effort of car manufacturers and insurance companies.

What Does A Transponder Key Do?

A transponder key uses two types of security features. One is the physical key that needs to be cut correctly to operate the cars' mechanical locks. The second is the chip inside, which the car must read and authenticate in order for the vehicle to start. For example, if the car's ignition is broken by a thief in an attempt to steal the car- then they will fail to steal it due to the secondary security provided by the chip in the key. Replacement keys are possible through an equipped locksmith- which is usually the cheapest option when getting a new or additional key for your car or truck.

Transponder can't be made until you authenticate it with the car lock. So before using it make your your key will be authenticated to use it easily.

Transponder car keys are usually designed in a way that will work when the particular matching code is provided. Unless the code matches, the car won't start .
