If you’re going to fret over the expense of forking over a good amount of money for a car key replacement, you might as well know why you are spending so much. Society puts a high price on security, and it is no exception when it comes to car keys. The high cost of replacement is often related to the sophistication of the car key, hence the term “Smart Key”. These types of keys go a long ways in thwarting attempts at grand theft auto.
So if you are the proud owner of a newer vehicle, chances are that you are also the owner of one of these Smart Keys. These keys have a transponder chip that is placed inside the key (typically inside the large plastic fob) that sends out a signal to your vehicle. Your vehicle is programmed to only accept a unique signal, and will not start unless it detects that signal. All this to ensure that it is indeed you (or at least your key) starting the car.
So next time you find yourself in need of a replacement transponder key, realize that is not just the key and the cutting that you are paying for, but also the necessary programming that matches your key with your car. It may seem like a high price to pay for a key, but it is a good line of defense against would be car thieves.
