Abstract
The safety of motor vehicles as an important issue has been an increasing number of car manufacturers into a major research projects, and that the safety of a vehicle in one of the most Crucial – Key system, it becomes increasingly important.
The graduation project is the subject of a rolling Keeloq code based on the technical design of electronic Key system. The system is a function of the Keeloq transmitter and receiver formed. Main function is to carry out the car anti-theft, but also for other access control systems. The system used to achieve SCM receiving, decoding and control functions, the use of HCS301 coding chip encoding and send data. The system's core is technology for the Keeloq rolling code technology. The system is highly secure, convenient, and cheap and so on.
