SOURCE: cannot disable anti theft alarm driving neighbours mad

There should be a relay under the hood for the security system, if you can not find it, try jacking the front of the car up, it should have a sensor that tells it that it is being towed and should turn off, unless of course it has a bad wire that is grounding out.

With the doors shut, insert the key into the drivers door lock. Lock and unlock the door 5 times. This should reset the system. If that doesn't work you should contact a qualified repair shop.

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.

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 .

How to disconnect anti theft


It is hard to give a definite answer because I don't know which and how many wires were damaged...Anti theft can be a real HEADACHE.....You can begin by disconnecting battery cables..Use your VIN number for parts,Get new ignition with a programmed factory key from dealer only.....They probably blew certain fuses and or relays when this happened...Or maybe not..Install new ignition connect battery cables..,turn switch on just to check for bad fuses and relays...Disconnect battery again...replace any fuses blown...Connect battery again...( Each time you disconnect battery it resets the computer system and should clear anti theft codes..)..make sure all doors are unlocked by using door remote key fob....Now see if vehicle will crank..If all is done correctly it should start...However I don't know how much damage was done.....It may possibly be too much work to totally disengage anti theft....You could start with removing all fuses and relays related to anti theft but disconnect battery before...I DO NOT RECOMMEND trying to disable the theft system.....You may create more headaches that you want.......Begin by trying what I described just to be safe...!!....

Transponder keys


I would check the circuits at the key switch first. The anti-theft should only affect the starter and engine, not things like power windows.

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)

Is there any way eliminate the anti-theft system on my 1999 windstar cause mine is malfunctioning and not allowing it to run (start). How many parts and connectors make up the system,anyways?


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

  • theft indicator
  • encoded ignition key
  • transceiver module
  • instrument cluster
  • powertrain control module (PCM)
  • standard corporate protocol (SCP) communication network
  • starter relay
The PATS uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock® in North America, Safeguard® in the U.K. and PATS in continental Europe. This information can be found in customer literature such as the Owners Guide.
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, with over 72 million billion combinations.
Each encoded ignition key must be programmed into the vehicle's instrument cluster before it can be used to start the engine. There are special diagnostic procedures outlined in the manual that must be performed if the encoded ignition keys need to be replaced.
The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This 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 the data to the instrument cluster.
The control functions are contained in the instrument cluster. This module performs all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling the engine enable. The instrument cluster initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP communication network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data when first installed together that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be performed if either the instrument cluster or the PCM needs replacement.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working properly, the vehicle will not start.
PATS uses a visual theft indicator. This 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 problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from perimeter anti-theft systems in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
PATS also disables the starter motor in addition to the PCM disabling the engine. When PATS disables the vehicle, it will neither crank nor start. If the instrument cluster is removed from the vehicle, the engine will not crank.
The starter relay is used as an additional means of disabling the vehicle engine. The starter relay is disabled when the PATS cannot read a valid encoded ignition key at ignition ON. The PATS will not store a diagnostic trouble code (DTC) or flash the theft indicator if a valid encoded ignition key is read but a fault occurs in the starter relay circuit.
The PATS is not compatible with after market remote start system, 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. Remote start systems must be removed before investigation of PATS-related no start issues.
