| Abstract |
Nowadays, there are several problems in using traditional mechanical keys
to open the doors at the office or home. The traditional method requires the
user to insert the key into the key hole to lock and unlock the door. This
makes it difficult for the user to lock and unlock the door, especially when the
user brings a lot of stuff. Originally, by using remote keyless system, the
lock is controlled by a keypad that is located at or near the door that evolve
pressing a predetermined (or self-programmed) numeric code for entry.
However, for this system, electronic remote control is used to lock and
unlock the door. In addition, when the user locks and opens the door, the
light will automatically switch on. It will ease the user, especially at night. The
light will turn on automatically by itself when user locks and opens the
door. |
