You are not reading the keypad properly. Look at the CustomKeypad example in the Keypad library examples for code on how to read a character from the customKeypad object. It looks like this:
char customKey = customKeypad.getKey();
Your code will be seen by more members if you post it correctly per the guidelines in the “how to use this forum-please read” sticky topics. Like so:
#include <Key.h>
#include <Keypad.h>

|| After connecting your keypad to your Arduino (as detailed below) and uploading
|| this sketch to your Arduino, you can then open the Serial Monitor on your
|| computer and ensure that the baud is set to 9600. Then press any of the buttons
|| on
the keypad to see the pressed button show up on the Serial Monitor.

|| Wire the keypad to your Arduino using information below:
|| Note: Pins one and seven on the keypad are labeled with little embossed plastic
|| numbers on the black connector
