I just encountered this very problem in my 2004 chrysler concorde lxi. i actually was stranded with two teenagers, at night, 50 miles from home. the problem, after two tow truck rides and a weekend without my car, was found to be the chip in the ignition key, which was odd, because I had no clue there was a chip in the plastic coated key. I was thankful, though, that the chrysler dealership could cut a new key and reset the computer/anti-theft system so that i could drive the car away. I suggest you try using a second key, if you have one. DO NOT use a copy key that does not have the chip in it. DON"T even insert it into the ignition. ever. Was a hard lesson learned for me.
I hope this helps you/answers your question. maybe atleast it will give you a place to start.

Would the anti-theft keep my 1999 ford windstar from starting


absolutely...

(No starter action at all)... If the starter is engaging not the trouble)

Your key as a weeny teeny transponder in it... which could get damaged(washing machine, dropped or broken).

Try THAT all important second key...
If the second key fails to get any starter action you DO need to look into your PATS (Passive anti-theft system),

Hope this helps.

Where is the anti theft box located on 2003 ford Taurus?


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 !

How can i find the anti theft reset button on 2006 taurus


this is for a 2003, might work.

1
Press the unlock button on your vehicle's key fob to deactivate the alarm. If you've misplaced your remote for the car, use the PATS programmed key to unlock the driver's side door. Then, put the key in the ignition and turn the key to the "on" position. The vehicle's battery should be on, but the engine shouldn't be running.

2
Locate the override button on the alarm box, beneath the driver's side of the dashboard. Press the button and hold it in until the alarm beeps one time. The LED light for the alarm should stop blinking, indicating the anti-theft system is disabled.

3
To reset the vehicle's alarm, put the PATS programmed key in the ignition and turn the key to the "on" position. Press the override button. When the alarm resets, it chirps two times and the LED light begins blinking.

Sorry you can't. Ford's suck because you have to have two keys to reprogram the security to the keys. Last one I had done cost about $200. Dealer only.

Vehicle will not start! Replaced the battery but it will still not turn over. Oil light, battery and engine light come on when initially trying to start.


Is the security light on or flashing when trying to start the vehicle .
Anti-Theft The passive anti-theft system (PATS) consists of the following components:
  • Anti-theft indicator
  • Encoded ignition key(s) (the key contains a transponder)
  • PATS transceiver
  • Powertrain control module (PCM)
PATS will disable the vehicle from starting if there is:
  • a damaged PATS key.
  • an unprogrammed PATS key.
  • a non-encoded key (a conventional key or one that does not have any electronics).
  • damaged wiring.
  • a damaged transceiver.
  • a damaged PCM.
If it is a anti-theft system you will have to take it to the dealer .This system will keep the starter from spinning the engine .

Does a 2001 mercury cougar have a chip in the key


Yes, it does........

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 Powertrain Control Module (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.

I had a key made and it desabled the security system in my 1999 mercury cougar and now the car wont start and I need to have it reset.


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.

2001 Ford Windstar, won't start, theft light on, van has a new battery


theft light should be flashing when system is armed. It should reset itself. If on steady, you have a probelem. Try your other key first. This inof should help you. Report back if you still need help.

Anti-Theft —Passive 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
--------------------------------------------------------------------------------
Principles of Operation
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 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a driveaway 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 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's powertrain electronic control (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.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The following will activate the PATS and will disable the vehicle from starting:
  • incorrectly encoded ignition key
  • damaged encoded ignition key
  • unprogrammed key
  • non-encoded key (key has no electronics)
  • damaged wiring
  • damaged transceiver
  • damaged PCM
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Large metallic objects, a second ignition key on the same key ring as the PATS ignition key or electronic devices on the key chain that can be use to purchase gasoline or similar items
  • Ignition lock cylinder
  • PATS key
  • Use of a non-PATS key
  • More than one PATS key on key chain
  • Central junction box (CJB) fuse 16 (15A)
  • Battery junction box (BJB) fuse 20 (15A)
  • PATS transceiver module
  • Ignition switch
  • Loose or corroded connection(s)
