Keyless door locks have become popular among homeowners in recent years. Although these locks were originally developed for use in cars with remote entry systems, they have been successfully modified for use in homes as well. There are a number of reasons to consider including a keyless door lock in your home. However, there are also some risks associated with this type of system, so it's important to consider all pros and cons before you install one in your home. One of the main advantages of a keyless door lock is not needing to carry a key. You'll no longer need to worry about losing your key or fidgeting at the door to get it open. It also means that you won't need to store a spare key somewhere on your property, as many homeowners currently do. Because most criminals are used to looking around to find a spare key, eliminating the need for one will help make your home safer. Another advantage of keyless door locks is that you can provide entry to your home for others at your discretion.
You will not need to make copies of a key or leave keys for dog walkers, housekeepers, or house guests to get in to your home. Rather, you'll simply need to tell those people the proper code in order to gain access. With the system in place, you can also tell exactly when and how people attempted to access your home. This gives you a good idea of how secure your house is. While there are many benefits to including a keyless door lock system in your home, there are also some major drawbacks to consider as well. While keyless door lock systems are generally safe and designed to alert police or other authorities if incorrect codes are entered too many times, it is nonetheless possible that an intruder may be able to gain access to your home through this system by guessing or hacking the code. Just as you can forget your keys and be locked out of your home, you can also forget the passcode to access your keyless entry system and be locked out. While it is safer to use a completely random code and avoid obvious choices like birth dates or simple, repetitive numbers, this can pose a problem if you have a difficult time remembering things.
One final disadvantage of keyless door locks is that electrically-powered systems may not function properly in the case of a power failure. This can leave your door completely locked throughout the failure, or it may result in the door not locking properly and remaining open. Fortunately, most systems have battery backup systems as a fail-safe. > > Install Keyless Locks Like a LocksmithPassword based door locking system, uses Matrix keypad to enter the password, This project is extended to operate on IR Remote RC-604, In this project all required data is given Circuit diagram, C code, PCB design and All related data, This project is based on AVR Atmega8 Microcontroller. 1.

Please comment if you have any trouble, Its Tested codeA keypad is often needed to provide input to an Arduino system, and membrane-type keypads are an economical solution for many applications. They are quite thin and can easily be mounted wherever they are needed.
In this tutorial, we demonstrate how to use a 12-button numeric keypad, similar to what you might find on a telephone. A 12-button keypad has three columns and four row. Pressing a button will short one of the row outputs to one of the column outputs. From this information, the Arduino can determine which button was pressed. For example, when key 1 is pressed, column 1 and row 1 are shorted. The Arduino will detect that and input a 1 to the program. How the rows and column are arranged inside the keypad is shown in the figure below. For this experiment, we demonstrate the “keypad.h” Arduino library. When a user presses a button on the keypad, the program will display the value the serial monitor. Connect the keypad to the Arduino as shown below. This is a very simple example, but I think you can see how easy it is to get keypad input to your Arduino program. You can use this type of input for many different projects, including:Password Based Door Locking System with 8051
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. These techniques are an integration of mechanical and electronic devices and highly intelligent. One of the prominent features of these innovative lock systems is their simplicity and high efficiency. Such an automatic lock system consists of electronic control assembly which controls the output load through a password. This output load can be a motor or a lamp or any other mechanical/electrical load. The main component in the circuit is 8051 controller. In this project 4×3 keypad is used to enter the password. The password which is entered is compared with the predefined password. If the entered password is correct then the system opens the door by rotating door motor and displays the status of door on LCD. If the password is wrong then door is remain closed and displays “ wrong Password access denied” on LCD. Working of Password Based Door Locking System with 8051
When power supply is turned on a message “Enter Your Password ” is displayed on LCD. We type the password using keypad which is attached with the system. If password does not match door remains closed and a message “wrong Password access denied ” is displayed on LCD. If password matched then a message “Password matched access granted ” is displayed on the LCD and motor rotates and door opened ,after some time door closed. Can be used in various rooms like seminar hall, conference room, and study rooms in college . The project (password detector) can be used to automate the door locking process, so the user need not to carry the door lock keys along with him, he can just remember the password and use it later to open the door. This project provides security. Power consumption is less. Used commonly available components. Project is simple and easy 1. Circuit Diagram of Password Based Door Locking System with 8051 1.
