Transponder Car Keys – Coded Keys

A: Transponder chip car keys were introduced around 1996 in order to improve the car security system or anti-theft system.

The idea behind the transponder chip keys is very simple: The key had to be coded to the car, so if someone makes a copy, it may turn the ignition, but will not start the car.

In addition, most of the times these keys require a special machine and equipment that only automotive locksmith or dealer carry and therefore make it harder to steal.

Furthermore, some transponder car keys, such as Chrysler and Toyota, also require a pin code, which, once again, can only be obtained by a professional locksmith or the car dealership.

  2. Most chances that you will need to use a special coding machine, which only the dealer or the locksmith has.
