In the rapid development of science and technology in modern times, thus improving people's living standard continuously. The property security problem is to focus on the people's attention. It becomes more and more important how security. The shortcomings of traditional mechanical lock is very clear: simple structure, low key anti-theft ability, easy to lose and duplication. Compared with the traditional mechanical lock, electronic code remote control infrared lock has high safety, low power consumption, easy operation etc.. Have been gradually accepted by the market. The design AT89S52 microcontroller as the core processing system of electronic remote control lock. The circuit of the corresponding simplified, in order to save the production cost objective. Electronic remote control lock through the program control external circuits, there are two kinds of input methods: keyboard input and control input. When the continuous input the correct password 2 times in a specified time, password lock can be opened, if the input error, it will alarm the alarm circuit. Because it is a simplified design, so the electronic lock with light as a substitute, alarm by buzzer sound operation. After finished the test object, test results show that the. This design is to meet the needs of the market.
