ABSTRACT
Remote control system is widely used now in the equipment such as television,
radio and are one more example used in trasports system as a keylock system. Remote
control system is divided to two categories; device based and activity based. Door is a
portable obstacle that can be opened up and closed. The combination between tool of
system remote control and door will produce one security system. This project will
focused the design of the safety system for house especially house door. This sytem is
constitute from the extension of remote control device to main system as a signal
receipient from it and activate or deactivate the keylock system at the door. The
objective of this design is to invent the keylock system that easy to used and easy to
maintain. This system also designed to give facilitate for disabled people to use the
door. Besides that this inventation also focusing for commercialization. So the
inventation of this project will be considering budget expenditure of the component and
raw material that will be used to produce one product that can be commercialized.

ABSTRAK
Sistem alat kawalan jauh merupakan sistem yang meluas digunakan pada
kebanyakan alat kawalan jauh digunakan pada alat elektrik seperti televisyen, radio, dan
pada sistem kenderaan sebagai sistem pengunci keselamatan. Alat kawalan jauh
terbahagi kepada 2 iaitu berasaskan peranti dan juga berasaskan aktiviti. Pintu pula
merupakan halangan mudah alih yang boleh dibuka atau ditutup. Gabungan antara
sistem alat kawalan jauh dan pintu akan menghasilkan satu sistem keselamatan. Projek
yang dihasilkan ini sebenarnya menumpukan kepada rekaan satu sistem keselamatan
pada pintu rumah. Sistem ini terdiri daripada sambungan alat kawalan jauh kepada
sistem utama sebagai penerima isyarat daripada alat kawalan jauh dan mengaktifkan
atau mematikan sistem pengunci pada pintu. Matlamat rekaan sistem keselamatan ini
adalah untuk mereka cipta sistem pengunci rumah yang mudah digunakan dan
diselenggarakan. Sistem ini juga direka untuk memudahkan golongan kurang upaya
menggunakan pintu. Selain itu, rekaan ini juga mensasarkan satu matlamat untuk
dikomersialkan. Jadi, projek ini direka dengan sebaik mungkin dengan mengambil kira
bajet perbelanjaan komponen dan bahan mentah yang digunakan untuk menghasilkan
satu produk yang boleh dikomersialkan.

CHAPTER I
INTRODUCTION
1.1 Overview
A remote control deadbolt lock was designed for quadriplegics. The system
consists of a modified standard household deadbolt lock, a central lock and a remote
control. People who have limited use and control of their hands would use this system
to simplify the complicated procedure of using a key to lock and unlock their homes at
the touch of a button. The purpose of this project was to simplify the tasks of locking
and unlocking a conventional door for people who use wheelchairs and have limited use
of their hands and arms. By incorporating the use of a remote control, the inconvenience
of using a key was eliminated. With just a push of a button, the locking mechanism in
the door can be activated or deactivated. There are several door-locking systems that do
not use a conventional key. There is a “credit card” type used in many hotels and the
push-button combination lock used in many businesses. Both of these and similar
systems did not address the inability of our client to grasp the card key or push the tiny
buttons. There are also variations of remote controlled doors and gates, but these tend to
be large and expensive systems more suitable for industrial use.

1.2 Project Objective
The objectives of this project are:
To design a remote control doorlock system for user to lock and unlock a
conventional door.
To commercialize this product to people.
1.3 Problem Statement
The problem statement of this project is divided into several aspects. In remote
control doorlock system, the construction of circuit for remote control is one of the
important aspects. In remote control system, it is divided into two part; transmitter
circuit and receiver circuit. If either one or both circuit is not function, the full system
would not work well. The central lock system is the main connector which connecting
the remote sensor to solenoid valve (actuator) and alarm indicator. If the central lock is
not developed, the system is not fully complete. So, the circuit must be constructed first
in electronic software. For my final project, the circuits are developed and simulated by
using Multisim, Proteus 7 Professional. From this software, the specification of the
circuits can be determined easily. For the design of the door and wiring diagram, the
Autocad software will be used to develop its.

In the remote control, there has a transmitter which send the data to the main
system which placed at the door. That main system consist a central lock which has a
receiver that will receive the sent data from the transmitter. The main system can not
directly switch on the system (opened up the door) because the main system needs to
connected and work together with the actuator to pull and push the lock door. In this
project, the two pneumatic actuators are used to work together with the main system.
The actuator consist a valve inside which require little pressure to operate and usually
double or triple the input force. The actuator is an electric motor drive. The electric
motor drive can have a speed-reducing transmission as may be desirable or required.
When the actuator is applying in between the system, it can create the great force to pull
and push the dead bolt easily.
Beside that, the arrangement of the complete wiring is important aspect need to
be focused in order to create the complete and safety locking system for the door. For
this aspect, the system needs something to keep the complete wiring. So, a piece of
Perspex is used to keep the all wiring set and the main system from anything that can
make a short circuit and disturbance in this system. The safety value which has in this
system can make it user friendly system whereas people can use it easily.

introduction about the project consist the overview, objective, problem statement and
scope of the project. A literature review of recent work on theory for the device and
concept involved and application is presented in chapter 2. Chapter 3 describe about
explanation about equipment, component, procedure, rule and technique applies in
developing this project. The simulation result, design and discussion about the system
will be showed and discussed in chapter 4. Chapter 5 introduce detailed about hardware
interfacing between hardware and simulation. And finally, chapter 6 summarizes the
contributions of this work along with suggesting avenue for future explorations.
CHAPTER II
LITERATURE REVIEW
This chapter consists of some information about remote control system which included
the central lock statement and also an overview of the literature that has been published
in relation to build the system.
2.1 Remote Keyless Entry System
A remote keyless system is a system designed to remotely permit or deny access to
premises or automobiles. This system was invented by mechanical engineer A.B.
Makkar. There are several remote keyless entry (RKE) systems on the market, including
but not limited to KeeLoq by Microchip, HITAG by Philips, and AVR411 by Atmel. In
the case of automobiles a remote keyless system performs the functions of a standard
car key without physical contact; power door locks can be locked or unlocked from
several feet away or even from inside a building. A remote keyless system can include
both a remote keyless entry system (RKE) and a remote keyless ignition system (RKI).
