Basically in case of the organizations and companies where the employees are required to produce the smart cards or proximity cards in order to get themselves authorized and recognized by the card readers present at the entrance gates of the companies. In the same way there is a way to get your vehicle secured and that is by means of the smart key. With the help of a smart key you can have an access to the electronically secure system. The smart keys are basically carrying the proximity key fobs which contain the secret code for every car. The function of these keys is the same as that of the proximity cards, which is to validate and authorize a vehicle before entering into the premises of a building and getting it parked.
