FORD 1998 Explorer - Manual (Page 65)

See also Remote entry system and Perimeter alarm system in this
chapter for more information.
Your vehicle has a factory-set 5 digit code that operates the keyless entry
system. You can also program your own 5 digit personal entry code.
The factory-set code is located:
• on the owner’s wallet card in the glove compartment
• taped to the computer module
When pressing the controls on the keyless entry keypad, press the
middle of the buttons to ensure a good activation.
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 five 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.
If you wish to erase your personal code, use the following instructions:
1 2 3 4 5 6 7 8 9 0
