I was given this project to use keypad, LCD display and a servo motor. The keypad will be used to enter the password, the LCD will display the password entered and the servo will unlock the door if the password entered is correct. PLEASE HELP ME! ANY HELP WILL BE APPRECIATED.
You were given this project, and you want us to do it, is that it?
The all caps subject won't help get people onside.
Hello and welcome, no need to scream, we can read anyway 
I suggest you use the Search feature of this forum.
Start by searching about LCD, you will find tons of infos on well supported LCD, with libraries, examples...all you need to show text on it.
Then search for "keypad", same, you will probably find everything you need.
As well for the servo...
Really, search, and only then, ask specific questions
