SECURITY CODE LOCK
ABSTRACT
Due to frequent unexpected access to restricted areas being encountered in our societies nowadays, from enemies or unwanted visitors, it has caused a lot of gatalities, inconveniences, data loss and serious business disruption, and other related damages. The Security Code Lock came into play in order to solve these problems.
Security Code Lock is a development of hardware base equipment security in the sense that, it makes use of “secret code” as mechanical, electrical or electronic device. The hardware is extremely easy to install with its high tech design, robust casing and stylish stainless finish, ensuring that it fits in most environment, from exclusive offices to stores and industrial premises.

CHAPTER ONE
1.0 Introduction
A security code lock is a flexible and versatile lock control system. It makes use of ‘code lock' as electrical, electronic or mechanical derive. It is a simple and secure method of locking equipment without having the need to directly operate the equipment by press contact. It removes the need for keys or buttons, taking away the hassle and cost of copying or replacing lost ones.
The new Encyclopedia Britannica, 1768 defines code lock as electrical/electronic/ mechanical device for securing an equipment so that it cannot be opened except by series of manipulations that can be carried out only by a person knowing the secret or code. The security code lock is a practical and code locking solution, ideal for commercial or residential premises, minimizing the risk of unwanted visitors gaining access to a restricted area-without impairing the dialing activities of tenants of staff.
With this hardware circuit we can lock up to one or more devices by a safeguard password chosen by the user to protect the system and as well unlock the system by entering an access code when the equipment is needed for use. An entry code reader transmits entered access codes to the controller. The controller compares the entered access to pre stored access codes and actuates the lock in response to the entered access code.
In case of power failure, the device will not create any problems, no operation or re-programming will be needed as well as all command are automatically memorized by the system and when the power is re-established the device restore immediately the last status of lock or unlock that had been commended.
