Can't find five diget code to keypad

I bought from used car lot and would love to be as to lock suv with the keypad but don't have the keypad code from factory
Is it hid on suv somewhere?
I have looked by fuse box but haven't found it and have read on the net that its by modular box but I am still having trouble locating where they put the five diget number for the outside keyless keypad for 2010 ford explorer
