In order to learn a new PATS system key you will need to have two original keys. You would insert one of the existing keys into the ignition. turn it on and off. you would insert the second existing key into the ignition and turn it on for at least 1 second and turn it off. Insert the new key, within 20 seconds, turn the ignition on for a second and turn the ignition off. the security light will will either flash or stay on for a couple of seconds (i don't remember specifically) to let you know you added the new key successfully.

Since it sounds like you are no longer able to do this you have two options.

1. you can pull the new lock cylinder out and have it coded to your original key and then use the original key(s) to start the vehicle.

2. you will have to have the vehicle towed to the ford dealer and have them program the new master key.

let me know if you have any questions and thank you for using fixya.con!

How to Fix a Sticking Ignition Key in a 2009 Ford Explorer, can start the car but cannot remove the key


This happens because the tumbler pins are dry and jam in their holes. Try a little bit of CRC or WD-40 beside the key and see if that releases the key. When you manage to get the key out blow dry the hole and use powered graphite to fix the problem as powered graphite is the lubricant used in locks

Reset security


I would not want to give you the wrong answer, but you need to be more specific about which component you replaced.
The tumbler would not have the same effect as the brain for the Security system. There are procedures for Coding a new Keychip to an established system and you would usually use one good Coded key to make a duplicate with certain button pushing combinations.
But to put in a different Brain, I am told, is a Dealer procedure to imprint and match the Brain and the Reader. Your old keys would need to be wiped and updated.
Since a Holiday Weekend is approaching, I wanted to give you some time this week to call the Dealer about this. Some other Expert may have more for you, but our suggestions will depend on which part you changed.

Installed ignition on 2003 sunfire, how do i reset security system


did you reuse the same pass lock sensor and key lock tumbler? if so the security system shouldn't have to be reset. if you replaced either lock cylinder or pass lock sensor then you have to turn the key to the start position and then to the run position and leave the key on for about ten minutes and wait for the security light to stop flashing. once the light stops flashing do the same process again. it may take up to three times to get the key code encrypted into the BCM. on the third time after the light stops flashing the car should start, if not then you may have another problem.

How can i unlock the ignition it is froze up and the key will not turn it has done this before but never for this length of time i have reported this problem to ford before and never gotten any response


You need a new switch tumbler. Also before installing you can take it and the door key to a locksmith and have them change the lock to fit your old key. This saves you from having to have two keys.

2003 Ford Focus. We inserted wrong ford key. Now the correct key won't turn when inserted. Anything we can do?


My opinion is that the only thing you can do is replace the ignition lock cylinder. I have seen stuck cylinders on the Ford Focus many times, and never successfully got one unstuck. This is a fairly common problem with the Focus.

2003 ford focus SE, WONT OPEN DOORS OR HOOD, Battery is dead dont have keys , they have to stay in the tumbler because broken pins.


You should be able to take proof of ownership and a picture ID to your local Ford dealer and they should be able to retrieve you key code on line and cut you a blank key(no pats) that would open the door.

Key stuck in ignition


Hope this helps all.... If the key is stuck (won't come out) and the column is NOT locked, one the gear shift there is a plastic sleeve. Put the gear shift in park...slide your hand below the knob and pull that sleeve up! Presto!!! it locks in park and the key comes out. I just put all the stuff i took apart back together... the other solutions may work but this is the first step to check... no tools and you know right away...
