INTRODUCTION
Department of Electronics & Tele Communication 2 25/10/2014
Password based door opener security system provides us ease with security.With the help of this system, we can easily avoid the incoming of any offenders , strangers too.
We can easily access our garage, home, offices etc. without the use of any kind of keys or opening it by ourselves.Hence,provide“AUTOMATION” & “SECURITY”.
NEED OF PROJECT

There are great varieties of digital code
locks. Generally speaking, they can be
classified into scores of type, such as electronic lock, fingerprint lock, card lock biological
lock, etc.
This kind of lock can avoiding the problems caused by the copying
of keys.
It is because the keys people carry have
become burden most of the time, but by
contrast people need only to remember a set of codes for electronics locks and don’t have to
carry any key, thus freeing themselves
from worries.
On the premise that it’s safety is high, it’s
another feature without key is getting more and more favour of people.
Among them the most practical and the most popularized one come to digital code lock.
OBJECTIVE

The objectives of our project are listed as above:
To avoid any crimes especially stealing
activities.
To help users and give them favour to
go anywhere.
To design a keyless door entry by using
electronic digital lock code.

APPLICATION
• Home access security.• Office access security.• Garage automation access.• Home automation access.
25/10/2014 Department of Electronics & Tele Communication 13
ADVANTAGES
• Simple installation.• Provide ease and automation.• Keyless system, hence no more worry of
losing of keys.• Since, it is the system having password
facility, provide security as well.

CONCLUSION
25/10/2014 Department of Electronics & Tele Communication 15
When we completed this project, we had learned and understand the process of
constructing the Digital Code
Lock which contained hardware and software development. We also
know and understand the microcontroller PIC and
how to implement it on my project.
Our digital code lock performed as expected. We were able to implement all the functions specified in
our proposal.
The biggest hurdle we had to overcome with this
project was interfacing the microcontroller with the hardware components.
This digital code lock is therefore particularly
useful in applications such as hotel room door locks, residential housing and even office buildings.
