VEHICLE SECURITY SYSTEM
First Claim
1. A vehicle security system comprising a first interface, one or more electronic control units, connected through a communication channel, wherein some vehicle functions related to said one or more electronic control units are accessible by using a vehicle access code (VAC) and wherein some or all information or data is communicated over said communication channel in an encrypted format, andwherein a secondary access code (SAC) is installed on said one or more control units and said first user interface, and said SAC is used to encrypt the VAC for at least the first time when installed on said one or more control units over said communication channel.
