Will inserting the wrong key in the ignition of a 2003 focus screew up the PATS? I replaced the key cylinder that had locked up. I inserted the wrong key (non PATS) The one for the doors. It turned the ignition but did not start the engine. After realizing my error I used the correct key but it will not start the car either. It does nothing. No click, the lights do not dim or anything. Like the car is not in park. But it is.

Try this

There are a few possible ways to reset the Ford Focus anti-theft security system. One way is to put the physical key in the lock, and then turn it to the unlock position. Do this, without moving it away from that unlock position for about 30 seconds. After that, You can unlock the car and start the engine.

What is the ford focus security system reset procedure?

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!

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

All you have to do to reset the antitheft system is to lock the doors with the key fob.

Your new key has to be programmed to your engine computer (PCM) before it will work.

To program, follow the directions in your owner manual. You need 2 already rpogrammed keys to do this.

If you don't have 2 programmed keys, your dealer will have to use his diagnositc tool to retrieve the information from the computer. Always have 2 programmed keys. I actually keep 3 in case I lose one, I still have 2 to program a 3rd one myself.

If you have AAA, have it towed to the delaer as a "no Start" so you don't have to pay the tow charge.

I assume this new ket is your only key now, or you could drive to the dealer with your spare key.

Passive Anti - Theft System (PATS)
The Passive Anti-Theft System (PATS) is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a miniature transponder within the key body. The transponder communicates with the powertrain control module through a transceiver mounted around the ignition switch lock barrel. The PATS functionality is incorporated within the powertrain control module.
PATS may be identified by a larger than normal sized ignition key. A larger sized ignition key indicates the presence of the transponder that controls the system.
The transponder code reading is carried out when the key, having been inserted into the ignition lock barrel, is turned from position ``0'' to position ``II'' to crank the engine. If the PCM receives the correct code, the engine will start. If the PCM receives either no code or an incorrect code the engine will not crank and PATS remains armed and the engine immobilised.
Anti-Theft Indicator
Whenever the ignition is switched on the anti - theft indicator will remain on for three seconds while the system reads the ignition key code.
The anti - theft indicator will flash rapidly or glow continuously after the initial three seconds to indicate the PATS has immobilised the vehicle.
For additional information on the PATS fault codes, refer to the Diagnosis and Testing section
-------------------------------------------------------------------------
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over four quadrillion combinations.
Each encoded ignition key must be programmed into the vehicle's powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic repair procedures outlined in this manual that must be performed if an encoded ignition key needs to be replaced
------------------------------------------------------------------------

03 dodge grand caravan - key will not turn in the ignition. i have replacement ignition lock cylinder and have followed your steps on replacing until the step of "insert key and turn to Run position" - i can't turn my key at all. How do I proceed from here? Thank you for your help!

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.

for 98 contour issue. TSB 98-21-14 not covered by warranty

This TSB article is being republished in its entirety to include the 1999 Cougar . ISSUE: The ignition key may be difficult to insert or remove and/or key chimes may sound with the ignition key removed and driver's door open on some vehicles. This may be caused by internal design characteristics in the ignition lock cylinder increasing insertion/removal efforts which may allow the lock cylinder to stick.
ACTION: Install a revised ignition lock cylinder. The revised ignition lock cylinder should reduce the possibility of high insertion/removal efforts and ensure proper chime function. Refer to the following Service Procedure for details.
SERVICE PROCEDURE

1. Verify customer concern.
2. Observe the ignition lock cylinder as the key is removed. If the lock cylinder snaps outward to the non-depressed position and the chimes stop sounding, continue to Step 3. If it does not snap outward, replace the ignition lock cylinder with the appropriate cylinder by referring to the Parts Block in this article.
3. Insert and remove the ignition key from the lock cylinder. If binding or high efforts are encountered, replace the ignition lock cylinder.
4. From the Parts Block, select a lock cylinder with a part number suffix identical to the center character of the key code of the vehicle. The suffix must match the center key code character to maintain a single key system.
5. Install the replacement lock cylinder, by referring to the 1998 Contour/Mystique Workshop Manual, Section 211-05 or the 1999 Cougar Workshop Manual, Section 211-04. NOTE: KEYS INCLUDED WITH NEW IGNITION LOCK CYLINDERS ARE CUT FOR THE IGNITION ONLY. IN ORDER FOR THE KEYS TO FUNCTION IN THE DOOR LOCKS, THE KEYS MUST BE CUT TO THE DOOR CODE OF THE ORIGINAL LOCKSET. THE KEY CODE WILL CHANGE UPON INSTALLATION OF THE REPLACEMENT LOCK CYLINDER (FIGURE 1).
   
   
   Figure 1 - Article 98-21-14
   
   NOTE: ADVISE THE CUSTOMER TO DISCARD ALL KEYS THAT WERE CUT TO THE ORIGINAL IGNITION LOCK CYLINDER.
