Can I disable OR remove the anti-theft device?

Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system 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.

youv've engaged the anti-theft circuit it will need reset at a dealer

had a similar problem and my chip was bad in my key

Well i have a 93 and the anti theft works by monitoring your hood, doors, trunk and ignition through various types of sensors. Has the ability to turn on horn, hazards, disable the starter. Sorry don't know what you mean by the latch that is connected will not budge. Do you mean the door handle? Ok the handle will not budge! Do not think that that is an anti theft system problem. I heard of the doors locking you might try a key. But on the 93's not even. So I think you have another problem. Good luck and thanks

this is in fact, part of your factory alarm... called PATS (passive anti theft system)

The actual "horn" should be coming from the rear right side of the cabin or behind the dash

This horn is built into the "computer" and there is little you can do at this point other than going to the dealer.

The dealer should be able to reprogram the modules in question to eliminate the "horn"

Try re-setting the computer...Disconnect the negative terminal of the battery and leave off for 5-10 minutes. This will allow the computer to reset. The charger may have interupted the signal or something.

to turn off the theft system, all you have to do is put the key in the door lock and lock and unlock the door, this shuts down the anti theft system,now this has nothing to do with the radio, the only way the radio would ask for the code is if it was removed or the battery unhooked,anyway try the unlocking of the door even try the passenger door, hope this helps.

Have you verified this system is running the battery down? The system you describe is called the Remote Keyless Entry System (Electronic Time/Alarm & Control System - ETACS Module). It cannot be 'disconnected' without disabling other systems (intermittent wipers, Chime bell, Door Warning, Dimming Off Room Lamp, Seat Belt indicator, remote power door lock/unlock system, etc.)

Section 13-11: Anti-Theft System, Active 1998 Windstar Workshop Manual DESCRIPTION AND OPERATION Anti-Theft Alarm System NOTE: The system immediately monitors the ignition key lock cylinder upon removal of the key from the ignition. It is not necessary to arm the system for ignition key lock monitoring.

The anti-theft alarm system:

• protects the vehicle from unauthorized entry into the passenger compartment, engine compartment and cargo area.
• monitors the status of the ignition key lock cylinder.
• is controlled by a remote anti-theft personality (RAP) module. The remote anti-theft personality module also controls the electronic door lock functions. Refer to Section 01-14B for more details.
• when armed, detects unauthorized entry into the passenger compartment by using an input from the GEM module regarding the state of the door or liftgate (open or closed).
• protects the engine compartment with a hood switch which is located on the LH cowl vent panel and is part of windshield wiper motor wiring (17A477) .
• triggers an alarm if the ignition lock cylinder is forcibly removed from the steering column.

Once triggered, the system responds by:

• flashing the low beam headlamps, the parklamps, rear lamps and the alarm indicator warning light emitting diode (LED).
• sounding the horn (13832).
• disabling the starter circuit until the system is disarmed.

---------------------------------------------------------------------------------------------
Remote Anti-Theft Personality Module

• The remote anti-theft personality module is located behind the instrument panel (04320).
• It contains a radio receiver that receives the RF signal from the keyless entry remote transmitter (15K601) through the alarm and lock system antenna (15603) and sends the appropriate command to the power door locks, the horn relay, or the generic electronic module.
• The remote anti-theft personality module is equipped with an internal backup power supply which holds the programmed code in memory in the event the vehicle battery is disconnected.

-------------------------------------------------------------------------------
Remote Anti-Theft Personality Module Removal

1. Disconnect battery ground cable (14301). Refer to Section 14-01 .
   

1. Remove radio. Refer to Section 15-01 .
   

1. Remove lower instrument panel center finish panel. Refer to Section 01-12 .
   

1. Lower glove box.
   

1. Remove two remote anti-theft personality module bracket retaining screws.
   

1. Disconnect electrical connectors and alarm and lock system antenna (15603).
   

1. Remove remote anti-theft personality module and bracket.
   

1. Remove remote anti-theft personality module from mounting bracket.
   

Installation

1. To install, follow removal procedure in reverse order.
   

1. Tighten remote anti-theft personality module bracket retaining screws to 6-8 Nm (54-70 lb-in).
   
   

Components The system is composed of the following components:

• remote anti-theft personality (RAP) module with integral antenna

The following vehicle components are also used by the anti-theft alarm system:

• generic electronic module
• power door lock switch (14028)
• door open warning lamp switch (14018)
• autolamp relay (14N089)
• horn relay and bracket (13853) and horn (13832)
• low beam headlamps
• rear lamps (13404) and parking lamps (13200)
• starter relay
• door lock relays
• keyless entry remote transmitter (15K601)

--------------------------------
Disarming an Untriggered System NOTE: A perimeter alarm will "shut off" after 165 seconds, but the system is still triggered and is not disarmed.

An armed but untriggered perimeter anti-theft system can be disarmed by one of the following four events:

1. Unlock the doors by pressing the keyless entry remote transmitter (15K601) UNLOCK button once.
2. Unlock any door with a key.
3. Turn ignition switch to RUN or ACC.
4. The remote entry PANIC button will disarm the anti-theft system only when the perimeter alarm is triggered and sounding.

------------------------------------------------
System Triggering NOTE: Although the remote entry PANIC alarm is not associated with the monitoring of the vehicle, the user will frequently say that the theft system was triggered when actually the keyless entry remote transmitter PANIC button was inadvertently pressed. A panic alarm will not flash the THEFT indicator.

The alarm can be triggered by the following events if the system has been armed and has not been disarmed first:

• Open any door or liftgate.
• Open the hood (16612) (if the hood was open when the system was armed, it must be closed before it can trigger the alarm).
• Dislodge the ignition key lock cylinder.
• The anti-theft system may be triggered inadvertently when the module is disconnected and then reconnected. To avoid inadvertent alarm triggering, disconnect the smaller 22-way connector first.

When the system is triggered the perimeter alarm will operate as follows: The remote anti-theft personality module will pulse the following outputs at approximately 1.3 Hz, 50 percent duty cycle for two minutes 45 seconds for North America. NOTE: Other perimeter alarms can be programmed for the system.

• low beam headlamps
• parking lamps
• horn
• THEFT indicator

The perimeter alarm can be retriggered, after a perimeter alarm has sounded for 165 seconds. After a perimeter alarm has timed out, if any trigger input is first seen as normal and is then seen in its trigger state, the perimeter alarm will be retriggered. The perimeter alarm can be triggered a total of three times between an arming sequence and a disarm event. An active panic alarm will be deactivated when a perimeter alarm is triggered (a perimeter alarm overrides a panic alarm).
