Sure, it's possible. Do you have any code so far? If so post it and I'll make some suggestions. I have one of these laying around so I can test.
Yes, its possible, you only need to use this statements:customKey = customKeypad.getKey(); and key = customKeypad.waitForKey();If you don't know how to use them I can give you an example of a loop to get the password.
customKey = customKeypad.getKey();
