Whether the car key replacement or duplication is needed, an automotive key programming mission is required; nowadays, all the keys of the vehicles feature transponders that include a microchip, and this chip is supplied within the manufacturing process of the car with a numeric code that is specific for this only car. Pressing the remote and once entering the ignition key, this chip sends the ID code in the form of frequent radio signals, and there is a receiver on the locks that takes these signal and identify if they carry the right codes for this vehicle or not; if there are no signals or with wrong codes, the car will not be unlocked or operated. The car makers, including Subaru, invent this technique to protect the vehicle from stealing attempts.
But this technique makes cutting the keys accompanied by the programming process, which becomes difficult for most local locksmiths, especially since each vehicle only has a special numeric code for it. That maks most vehicle owners resort to the dealerships when it comes to keys services, while the situation is different for Subaru drivers in Round Rock, Texas, as they can get car key-programming machines on-site at the best quality in a short while by calling Subaru Key Replacement.
