Why do you have to have two programmed ignition keys in order to program a new chip key. ?

Pawel Nietyksza has no clue ,don't wast your time looking for a programming button, there isn't any. You need a factory or some other type of professional grade scan tool to program the key for anti-theft system immobilizer.

You must have chip keys. If you get 3 you can program a new one yourself. Call dealers and get prices and call locksmiths and get prices. Vary greatly.

waste of time its a chipped key .order a new key from dealer and then it has to be programmed

You can't use a non chip key. You need to get it to a dealer for programming(some locksmiths can do it). Just a note, you need 2 keys for programming on Fords. Thing is you need to have the problem diagnosed. If you just lost the key. Take it to Ford. They can cut new keys for your truck and program them. Have the codes read. Receivers don't have to be reprogrammed. You could have a bad wire or plug. All the other computers have to be programmed.

In order to program a new key, you have to have two working keys that are already programmed. The engine control is programmed that way to prevent a parking valet from programming their own key.
YOU MUST HAVE TWO WORKING KEYS or the controller will shut off the engine.


The locksmith should have changed the pins in the new lock to match your original key. The controller would have recognized it and let you drive the car. So, you either need to call the locksmith back to fit the old key to the new ignition cylinder, or get it to a dealer so they can instruct the brain to accept the new key. And get two keys while you are at it as a back up.

nitabelle57, It sounds like your security system will not recognize the new key you purchased. Keys have a chip in them which has to be recognized by the security system in order to work. The new key has to be programmed by your security system before it will start your vehicle. You will need a battery charger to program the key as this procedure takes thirty minutes to do. Put the charger on the battery. Be sure everything else is turned off. Place the new key in the ignition and turn it to the run position. The security light should come on. After ten minutes the security light should be out, if not proceed anyway. Turn the key to the off position but do not remove it. Wait five seconds and turn it to the run position once again. Wait another ten minutes and turn it off again. Wait five seconds and turn it to the run position once again. After the final ten minutes turn the key off (do not remove it) Wait thirty seconds and then the key should be programmed. If you have any other keys they will not work now as the security system is now programmed for the one key. If you have another key and need it for another driver then start the vehicle with the newly programmed key and let it run for about a minute. Place the extra key in the ignition and turn it to the run position and wait sixty seconds. This should solve that problem. Good luck with this.

There no way runs through your computer, your truck is in theft mode, most lock smiths have the computer to program a chip to your pag system, you have a key already won't be that much to do.

You must get a new ignition at dealer, then your dealer will have to program the key it will never start without that chip..

your ignition will only recognise the original key because of its resistance. you need to order a new key from the manufacturer.

Here is the factory procedure to program a new key(s), I recomment only factory keys, you need to use the working key to do the procedure;
1. Insert a previously programmed coded key into the ignition.

2. Turn the ignition from the 3 (OFF) position to the 4 (ON) position. Keep the ignition in the 4(ON) position for at least one second, but no more than 10 seconds.

3. Turn the ignition to the 3 (OFF) position, and remove the coded key
from the ignition.

4. Within ten seconds of removing the previously programmed coded key, insert the other previously programmed coded key into the ignition.

5. Turn the ignition from the 3 (OFF) position to the 4 (ON) position. Keep the ignition in the 4 (ON) position for at least one second but not more than 10 seconds.

6. Turn the ignition to the 3 (OFF) position, and remove the second key from the ignition.

7. Within twenty seconds of removing the previously programmed coded key, insert the unprogrammed key (new/valet key) into the ignition.

8. Turn the ignition from the 3 (OFF) position to the 4 (ON) position. Keep the ignition in the 4 (ON) position for at least one second.

9. Your new unprogrammed key is now programmed. If the key has been successfully programmed it will start the vehicle’s engine and the theft indicator light will illuminate for three seconds and
then go out. If the key was not successfully programmed, it will not start your vehicle’s engine and the theft indicator light will flash on and off rapidly. If failure repeats, bring your vehicle to your dealer to have the
new key(s) programmed.

To program additional new unprogrammed key(s), repeat this procedure
from step 1 for each additional key
