<HR>On-Board Programming Method "C"
for Ford keys (Later 1998-newer Ford, Lincoln, Mercury)
If you want to initiate a new master key....
1. This requires that the vehicle be connected to special dealer equipment. There are two ten minute delays involved while this device erases all existing key programming and sets up the vehicle computer to accept new key codes. Two new keys should be ready because the system requires a minimum of two keys in the program. After the first two keys are programmed, additional keys can be entered individually by following the instructions for adding duplicate keys (below).
If you want to add a key....
**You must have two original keys to perform this procedure. If you only have one key, you WILL have to take it to the dealer to get it programmed**
1. Insert and existing (working) key into the ignition cylinder.
2. Turn the ignition cylinder ON (RUN) and back to OFF. Ignition should stay on for at least ONE SECOND.
3. Remove the existing key and, within TEN seconds, insert a second working key and turn it to ON (RUN) and the back OFF. Ignition must be in ON for at least ONE second, but no more than TEN seconds. Remove the key.
4. Insert the new key before TWENTY seconds have elapsed and turn it to ON (RUN). Leave it the ON position for at least ONE secondand turn back to OFF.
5. The security light will light up for THREE seconds to indicate that the new key has been successfully programmed.
6. To program additional keys, repeat steps 1 through 5
As a precautionary measure for all of the above procedures, you should wait at least one minute after you have performed this until you start your vehicle.

SOURCE: does 98 ford explorer has a microchip in the key
Yes it does have a microchip did they replace it with the right key switch and try unplugging the negative battery cable for about a minute to reset the computer
SOURCE: CAN I PROGRAM THE KEY
Unfortunatley, most dealers keep a pretty tight lid on reprogramming the key fobs. You may find someone that had the software to do it, but chances are you will have to take your key in to have it flashed
SOURCE: 98 ford explorer park lights won't go off
This is usually a light switch issue. If you have the pull out knob- make sure the nut that holds the switch in place is tight. If the nut is tight, replace the switch as a first step.
There is a much lesser chance the signal switch failed and it is actually brake light power lighting them.
SOURCE: Can't find computer in my ford explorer 98
When you say computer you have to define what your refering to
The main PCM I looked into with google & are ten different answers
ays well as pictures
There are other modules so I suggest you use google when
you know what one your looking for
Why the qusetion?
You can't test it & surely don't want to
replace it on a wish & hope theory that will
solve some vehicle problem
They don't fail often, so have a repair shop diagnose
the real issues
SOURCE: Why won't my 98 Ford explorer start? My theft
try using a spare key.
Either way if it starts or not with the spare key a trip to the ford dealer may be in your future. occasionally the security system will forget your keys. You can program them yourself but you will need two keys that work. If you have two keys that work let me know and I'll let you know how do do it.
If you do not have two keys that work than the ford dealer will have to reprogram your keys into the security system.
