    What Is A Smart Key

    A smart key is an advanced version of an automobile key, one that allows for keyless entry into your vehicle. The cars onboard computer can detect when the key is near the vehicle and will allow entry into the vehicle without you having to unlock the doors manually.

    The car also detects the key while you are inside the automobile and models like the Toyota Prius are equipped with a push-button starting system. As long as the key is in the vehicle, you can just push a button to start the engine of your Prius. It doesnt need to be inserted into the ignition: It can be in your purse, your pocket, in the cupholder, or anywhere within range of the onboard computer.

    Another benefit is that your car wont let you lock a smart key in the vehicle. It knows the key is there and will prevent the doors from locking. Plus, the smart system automatically locks the doors once you get far enough away from the vehicle.
