The increasing rate of crime, attacks by thieves, intruders and vandals, despite all forms of security gadgets and locks still need the attention of researchers to find a permanent solution to the well being of lives and properties of individual. To this end, we constructed a cheap and effective security system for buildings, cars, safes, doors and gates, so as to prevent unauthorized person from having access to ones properties through the use of codes, we therefore experiment the application of electronic devices as locks.
However, a modular approach was employed in the construction in which the combination lock was divided into units and each unit constructed separately before being coupled to form a whole functional system. During the construction, we conducted five testscarried out with the first three combinations being four digits number, the next two tests being five digits. From the result obtained, combinations (2), (4), (7), (8) gave the correct output combination. The general operation of the system and performance is dependent on the key combinations. The overall system was constructed and tested and it works perfectly.

Consequently, there is a need for other types of locks especially electronic ones. To this end, we c ... Continue reading---
