Step-by-Step Guide on Subaru Transponder Key Programming [7-Simplest Steps]

Car theft has been prominent in our society since the very beginning. Earlier, it was done using the hot wire technique of unlocking and starting the car.

That’s why the transponder key came into existence after 1985 to reduce the chances of car theft.

To program a Subaru transponder key, first, select the valid key and access the programming mode. Afterward, follow the instructions properly, and test the key to ensure proper functionality. The process requires special equipment and knowledge, and can only be performed by a Subaru dealership or authorized service center.

Moreover, it is well-equipped with a radio frequency identification chip. Also, it makes hot-wire unlocking system ineffective.

General Motors introduced this technique in the market to promote anti-theft of commercial and personal vehicles. It needs to be programmed before taking into work.

Therefore, if you are using Subaru vehicles on a daily basis, you must know how to do Subaru transponder key programming.

Here I am adding a step-by-step procedure for making this task easy and straightforward.

What is Transponder Key?

Subaru Transponder Key Programming

A transponder key is a chip-based security system that disables the hot wire mechanism while trying to unlock the car without the consent of the car owner.

It has an RFID chip installed in its plastic head. The following key facts will make the features and working mechanisms clearer:

  • The chip available in the transponder key sends the signal to the immobilizer or car’s receiver. The car will not start without receiving the correct signal and code that matches the code saved in the car’s system. This means that if anyone with wrong intentions could even unlock the car, he won’t be able to start it.
  • The built-in mobilizer needs to recognize the digital code sent by the transponder key to disengage. A transponder key needs proper programming before it can be used to its full potential.
  • Car manufacturers adopted this technique as a security measure and reduce the frequent theft of vehicles.

After you have kept the key in this position for 10 seconds, turn the key back to the “Off” position, then remove the key from the ignition.

4. Insert the unprogrammed key:

Ensure you complete this step perfectly and speedily.

Within ten seconds of pulling the programmed key, out the other key into the automobile. Do not delay more than this time limit.

After 10 seconds, turn the key back to the “Off” position, then remove the unprogrammed key from the ignition.

7. Test the new key:

Test the new key by inserting it into the ignition and starting the engine. If the key works, the programming process is complete.

If the key does not work, repeat the steps above.
