how to change the door keypad code on a 1995 mercury courgar

l had a 89 LSC and do remember that you can only add a new code but not delete the existing code. the instructions on how to do it was in the owner is manual But l can not remember how it was done

Why do you need it changed l am sure the previous owner is done with that car if it is new to you If you forgot it, look in the trunk on one of the arms it is usually posted there or on the premium sound factory amp if you have that

Here we go again, you can not change the factory code, you have to replace the key pad. get either a new one from Ford or a used one from a wrecking yard, make sure you get the code.
