Anti-Theft -Passive Anti-Theft System (PATS) The passive anti-theft system (PATS) contains the following components:

• theft indicator
• encoded ignition key
• transceiver module
• PATS control module (located behind the passenger side air bag module)
• powertrain control module (PCM)
• standard corporate protocol (SCP) communication network

Taking the vehicle to a qualified repair shop that has the diagnostic tool to read the DTC'S - diagnostic trouble code's . Then they can diagnose the problem . None of the thing's you tried will work , not for anti-theft systems , not suppose to. The computer isn't seeing the correct transponder code or the anti-theft module is the problem . Having the vehicle checked by a qualified service tech is the only way to resolve your problem .
Ford's PATs - Passive Anti-Theft System Information. Permalink
Many Ford trucks, vans and suvs use PATs (passive anti-theft) keys. These keys prevent someone from copying your key to a blank and using the blank. There is a small chip in the key which the vehicle must recognize before it will start.
PATS is Ford Motor Company's passive anti theft system. In 1996 it started showing up on select models of Ford and Lincoln Mercury vehicles. The keys for these vehicles have a tiny radio frequency transponder imbedded in the plastic Head.


When you attempt to start the vehicle, the onboard computer sends out a RF signal that is picked up by the transponder in the key. The transponder then returns a unique RF signal to the vehicle's computer, giving it the ok for the vehicle to start and continue to run. This all happens in less than a second, and is completely transparent to the vehicle operator. It is a very effective system that does its job without the vehicle owner having to think about it, or modify his / her usual routine.

The PATS - passive anti-theft system is a program (software ) programmed into the instrument cluster , PCM - engine computer , GEM module etc... Plus behind the plastic shroud on steering column where the lock cylinder is located the passive anti-theft transceiver module ! You better know what your getting into when you start to mess with anti-theft systems , you can render your vehicle useless if your not careful ! Need factory scanner to program keys , to read trouble codes , check data etc... If you change transceiver module it will need to be programmed ! FORD DEALER ONLY ! You can program more keys but need to have original two keys that came with the vehicle or you can't do it >
Passive Anti-Theft System (PATS) -Principles of Operation 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 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a drive-away theft. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with non-Ford aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped, the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
The correct ignition key is a different design than prior model years. Please consult the Rotunda Key Ordering Guide for the correct part number.
So , before messing with something you know nothing about , do yourself a favor , take it to the nearest FORD dealer !
So

Explain anti-theft fuse box ! what do you think this is ? There is an anti-theft system on your vehicle , called PATS - passive anti theft system .Sorry , but there is not anti-theft fuse box .
Anti-Theft -Passive Anti-Theft System (PATS) The passive anti-theft system (PATS) contains the following components:

• theft indicator
• encoded ignition key
• PATS transceiver module
• powertrain control module (PCM)
• standard corporate protocol (SCP) communication network

Hi Carol , do you mean PATS passive antitheft system ? Locked up your car ,do you mean it won't crank over an start ?
The passive anti-theft system uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user.

• During each vehicle start sequence, the ignition key identification code is requested by the vehicle protection anti-theft electronics.
• If the key's ID code has been programmed into the system, the powertrain control module (PCM) (12A650) is signaled to enable the vehicle to start.
• If the key's ID code is not programmed into the system, or if no encoded key is detected, then the powertrain control module is signaled to disable the vehicle.

The passive anti-theft system communicates the state of the security system to the powertrain control module via the J-1850 communications network data link connector (DLC). The powertrain control modulebased on the communications from the passive anti-theft system, will determine if the vehicle's engine is enabled to start. The passive anti-theft system differs from the active anti-theft alarm system in that the passive anti-theft system enables/disables the vehicle from starting and only operates with the ignition switch in RUN/START position. The active anti-theft alarm system has perimeter protection capabilities and operates only with the ignition switch OFF. Refer to Section 13-11A for active anti-theft alarm system information.
Vehicle Disabling The passive anti-theft system will be activated and disable the vehicle from starting if any of the following conditions exist:

• damaged encoded key
• unprogrammed key
• non-encoded key (key has no electronics)
• wiring concern
• transceiver concern
• Passive Anti-Theft System (PATS) control module concern
• J-1850 Communications Network concern
• Powertrain Control Module (PCM)

ANTI-THEFT SYSTEM Passive anti-theft system
Your ignition key has a unique imbedded transponder which engages engine electronics and allows the vehicle to be started. Without the use of your special ignition key, the vehicle will not start.

During each vehicle start, the coded key is read by the anti-theft system. If the key’s ID code matches the code in the anti-theft system, the vehicle is enabled to start.

Briefly illuminates when the ignition is turned to the ON position to verify that the passive anti-theft system is operating properly.

Also, its possisble that tou have actovated the fuel pump switch.

CHeck it.

It sounds like the vehicle is in theft mode,did you use a different key? Does the theft light blink really fast with the key off?If the passive anti-theft system has been activated the computer will have to be reset in order to get the vehicle running again.

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).
