    Le me try to understand what u mean, you think the ignition lock cylinder is locked because of the anti-theft? I assure you the anti-theft can not do that, all it does is disable the fuel pump circuit.

U must dis-arm the airbag 1st, disconnect the battery for 30 minutes before you begin work, then remove the airbag, the retaining screws are at the back of the steering wheel down in holes I believe, after that remove the safety clip at the top of the steering wheel threads, then the steering wheel nut, you will need a steering wheel puller to remove the steering wheel, they are about $10 from any parts store, after the wheel is removed remove the airbag clock-spring rotating contact, then remove the turn signal switch, there will be 3 screws holding the turn signal switch in, remove them, then remove the lower trim under the dash and crawl under and and disconnect the large flat connector at the bottom of column, this will allow u to pull the turn signal switch up and out of the way, don't force anything be patient, under the turn signal switch on the right of the area above the ignition lock cylinder u will see a black headed screw, it may be a tamper proof torx/star screw head or a phillips, remove it, then turn the ignition to the on position and slide the ignition switch out, reverse it all and put it back together. take your time, don't rush, good luck, contact me with any further questions.

Why won't our Ignition switch unlock?


I had a similar problem with my 2004. I changed the cylinder. Its amazing how much of it is plastic. Over time it wears. You will have to disable the Air bag system and pull the steering wheel. You will need a steering wheel puller and another tool to push it back on. You also have to transfer a part from the original switch to the new one so don't immediately chuck the old one. Afterwards you have to reset the anti theft.

Remove ignition lock to switch link 1995 suburban


The ignition lock assembly contains two components: a lock cylinder to deter theft and an electrical portion that supplies power to electrical components such as the radio, electric windows, and windshield wipers. The electrical portion of the ignition switch also provides power to the starter motor to start the engine.
The ignition lock is an anti-theft device that prevents a vehicle from being driven unless the ignition key is in the ignition switch. If the ignition key is not in the ignition switch, it 's impossible to turn the steering wheel.
To replace the ignition switch cylinder lock, the trim panels around the steering wheel are removed. Then the tamper-proof hardware that attaches the ignition lock assembly to the steering column is removed. The ignition lock assembly is removed from the steering column, and the lock cylinder is replaced. The new ignition lock is reattached to the steering column, and the trim panels are replaced.make sure you dissconect battery first the 1997 had a recall on the ignition switch dont no if the 1995 had a recall if so they will replace for free

Theft system locked


To get the key out; look under the steering wheel for a plastic flat head screw. untwist it and then push the spring in and your key will be free. Then, go to your fuse box and remove the main fuses and you will hear the doors unlock when the system reset itself. Plug them back in and start your car. This just happened to me... seems the only things that were working were the navigation screen, headlights, fog lights, and reading light on the inside. Dash board was all dark except the engine light.

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).

    34bdf35.gif
Components The system is composed of the following components:
  • remote anti-theft personality (RAP) module with integral antenna
  • alarm indicator LED
  • door lock cylinder switch RH, door lock cylinder switch LH
  • liftgate door lock cylinder switch (220A40)
  • hood switch (part of windshield wiper motor wiring (17A477))
  • ignition lock anti-theft switch (19A438)
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).
