INTRODUCTION
Digital Code Lock
using AT89C2051 is
Digital
a basic control
code lock
system with an
ability that allows

changed by the user.
This circuit is
eminently suitable
as a digital lock with
security option.
This type of
lock use
numerical
code for
authenticati
on where the
correct code
must be
entered in
order for the
lock to
deactivate.
The lock can be used
with an outdoor gate or a
normal door. The
functionality of this lock
is implemented in
software
When the correct code is
entered it will open the
door. The significant of
this project is to
eliminate the need for a
key.
NEED OF CODE LOCK
This kind of
lock can
avoiding the
problems
caused by
the copying
of keys.
On the premise
that it’s safety is
high, it’s
another feature
without key is
getting more
and more favour
of people
OBJECTIVES
To free users from the worry of remembering keys
To design a keyless door entry by using electronic
digital lock code
To avoid any crimes especially stealing activities

ADVANTAGES
1.
NO NEED TO POWER OFF THE SYSTEM
• WHEN SYSTEM IS BLOCKED AFTER UNSUCCESFUL ATTEMPTS THEN JUST ENTER
THE MASTERCODE ,THE SYSTEM WILL BE UNBLOCKED.SO THERE IS NO NEED TO
‘POWER OFF’ THE SYSTEM FOR RESETTING.
2.
NO NEED TO ENTER CODE TO LOCK AGAIN
• THERE IS NO NEED TO ENTER THE SECURITY CODE TO LOCK THE SYSTEM AGAIN,
JUST PRESS THE ‘#’ KEY TO LOCK AGAIN.
3.
PREVENTION FROM HACKING
• EVERYTIME THE SECURITY CODE CHANGES IT IS NOT SAME FOR ALL THE CASES ,
AND THE PERSON WHO KNOW ABOUT THE SYSTEM THOROUGHLY ONLY HE CAN
CHANGE THE CODE.SO THIS THING PREVENTS THE SYSTEM FROM HACKING.
FUTURE ENHANCEMENTS
1.
CONTROLLING ELECTRICAL DEVICES
• ELECTRICAL DEVICES SUCH AS LIGHTS, COMPUTERS CAN BE
CONTROLLED BY USING SEPARATE PASSWORDS
2.
AS AN ATTENDANCE REGISTER
• We can use this system as an attendance register for the
students to enter a
class room with their respective password.
3.
TIGHT SECURITY
• The system can be easily connected to the personal
computer for further control. Other than the speaker
sounds, all the lights can be made to turned on if password
entered is wrong for three times and also a hidden camera
can be used to record the faces who trespassed.

CONCLUSION
This digital code lock is therefore particularly useful in
applications such as hotel room door locks, residential
housing and even office buildings.
We feel that this digital code lock is very marketable
because it is easy to use, comparatively inexpensive due to
low power consumption and highly reliable
Lock which contained hardware and software development.
We also know and understand the microcontroller
AT89C2051 and how to implement it on my project
