appreciate your codes but i need something that would work with my project as im not using keypad.h. I also have the following codes that works like a charm but with 8 pins of Arduino.

 Hello world! This code is made to put a 
 access code/password protection on your dangerous machines in the garage/work place for example.
 To protect your kids from the danger that might lurk in your garage, without the code.
 power cannot be turned on. Hide it in a box with that you can lock on the wall
 and add a little safery to your garage. Of course it can be used to turn on/off anything.
