FORD 2002 Explorer v.3 - Manual (Page 125)

Programming your own personal entry code
1. Enter the factory-set code (keypad will illuminate when pressed).
2. Press the 1/2 control within five
seconds of step 1.
3. Enter your personal 5 digit code.
Enter each digit within five seconds
of the previous one.
Do not set a code that includes
three of the same number or
presents them in sequential order.
Thieves can easily figure out these
types of codes.
Your personal code does not replace
the permanent code that the
dealership gave you. You can use
either code to unlock your vehicle.
If a second personal code is entered,
the module will erase the first personal code in favor of the new code.
To exit, press 7/8 and 9/0 simultaneously or allow more than 5 seconds
to elapse since a button press occurred and the 5 digit keycode will be
programmed.
