You know how to use your smart phone, smart TV, smart watch --- why not your smart key? Toyota Smart Keys allow you to automatically unlock the doors and start the vehicle without the use of a mechanical key.
With the intelligent key fob on your person, you simply have to put your hand on the door handle and it will sense this and unlock. This is a lifesaver, especially if you have to load a lot of cargo into your vehicle. Once inside the vehicle, just "push to start" and go!
