How to program my key to 98 ford explorer


for Ford keys (1996 -early 1998 Ford, Lincoln, Mercury)

If you want to initiate a new master key....

1. Insert new key into ignition cylinder and turn it to the ON (RUN) position. The security light on the dash will flash for fifteen minutes.


2. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light on the dash will flash for fifteen more minutes.

3. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for fifteen more minutes.

4. After the security light stops flashing the third time, the new key has been programmed into the vehicles computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicles computer.
If you want to add a key....


1. Insert an existing key into the ignition cylinder.


2. Turn the ignition cylinder to ON (RUN) and back to OFF.

3. Remove the existing key and, within 15 seconds, insert the new key and turn it to ON (RUN).

4. The security light will light up for two seconds to indicate success in programming the key into the vehicle.

5. Don't attempt to start the vehicle with any key for at least 1 minute.
<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.

How do I reset anti-theft on a 1996 Ford Mustang after replacing the ignition?

NOTE: This procedure will erase all programmed ignition keys from the vehicle memory and the vehicle will not start until two keys have been reprogrammed to the vehicle.
NOTE: Two PATS encoded keys with the correct mechanical cut must be available to perform this procedure. One or both of them may be the customer's original keys.
NOTE: If additional keys are to be programmed, refer to Key Programming - Program a Key Using Two Programmed Keys. If the remaining keys are with the customer and are not available with the vehicle, then instruct the customer to refer to the Owners Guide under the "Programming Spare [SecuriLock ® (North America), Safeguard ® (U.K.) or PATS for all other markets] Keys Procedure" for instructions on programming the remaining keys.
  1. Turn the ignition switch from OFF to RUN.
  1. Enter New Generation STAR/Service Bay Diagnostic System (NGS/SBDS). Follow the SECURITY ACCESS PROCEDURE to obtain security access.
  1. From NGS/SBDS menu, select IGNITION KEY CODE ERASE.

Why does the security light flash even when key is on and engine will not start?


The security light flashing is the indicator. The fuel pump is disabled by the ECU because the immobilizer system does not recognize the transponder chip inside the key.

There could be several causes.
a. Either the transponder chip inside the key is bad, not programmed, or missing
b. The antennae that is located around the ignition lock is bad and/or not reading the transponder chip inside the key.
c. There is a wiring issue between the ECU and antennae.
d. The ECU is bad

You may want to seek out a qualified mechanic or automotive locksmith for help, not all mechanics and/or locksmiths are capable of handling the immobilizer systems on these vehicles. So be clear when discussing your problem to them and make sure they are capable of handling this type of problem.

If the key is not original, check to see if it is a cloned key. Some cloned keys use batteries, when the battery inside the key dies, it no longer communicates with the vehicle. Although it's not common, regular transponder chips can go bad, usually due to physical damage.

An immobilizer transceiver coil tester can be used to test the signal from the antennae at the lock cylinder.

If the ECU is determined to be bad, a used ECU with matching part numbers can be used as a replacement. Contrary to what a dealership or some shops may tell you, all that is required is an immobilizer reset service on the used, replacement, ECU to get it to function with your vehicle. A used ECU and an Immobilizer Reset Service is much cheaper than a new ECU from the dealer. Make absolutely sure that this is the problem before going this route though.

Security Issue


Usually the flashing security light means the computer is not finding the right code in the key chip.
Is the key you are using programmed to the vehicle ?

Car was stolen ignition was ripped out of 2002 grandam, now car won't start with ignition and security light keeps flashing


groan.....gunna need a bit more info. but i'll try. What portion of the ignition was ripped out? The tumbler + switch? If so, you might need to get the car's system resent to recognize that it has a new ignition put in. Sime vehicles have a theft prevention system in place to prevent the vehicle from running if its been hot wired. Your best bet would be to replace the damaged ignition components (You did not mention if you did or not). If it still doesn't work after you have replced all of the ignition components. You can try to reset the vehicle (doesn't work on all) disconnect negative battery terminal and go back into vehicle and press down the brake pedal for about 30 seconds then reconnect battery and try it....good luck, hope this helps

No keys

2. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light on the dash will flash for fifteen more minutes.

4. After the security light stops flashing the third time, the new key has been programmed into the vehicles computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicles computer.

The dealership should be able to do this for you without a current key, of course this means towing the vehicle to them. See if they will sell you a key and you program it yourself.

hope this helps. I found the above info at FordF150.net
