No power in any systems - anti theft?? How do you reset?

Batteries in the remote died and unlocked the driver door manually but no systems came on when I tried to start the vehicle. Replaced the batteries but now there is no power. I am assuming it is the anti theft system. How do you reset the system?

You should have a card with the set of keys with the reset code printed on. The other poss solution, which worked for me, was to disconnect the negative battery lead, wait for 30 seconds, and reconnect, the system should reset.

2004 chevy malibu driver and passenger door lock problems


The locks on your vehicle are electronically controlled by the BCM - body control module . The driver an passenger door switche's are input's to the BCM . Do you know anything about automotive electronic's ? anti theft alarm remote, could this be part of the problem , No it's just a key less entry remote , nothing to do with the anti-theft .
Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• IBCM (PWR) 15-amp fuse

Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch Lock or Unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation
• An automatic door unlock actuation
• A last door closed locking (LDCL) actuation

Driver and Passenger Door Unlock Operation w/o Keyless Entry
When the body control module (BCM) detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the driver passenger door lock actuators transition to the Unlock position.

Your best bet , take your vehicle to a qualified repair shop ! Need special tool to diagnose .

Car dies when I use my remote start and press the lock or unlock button


This is most likely caused by the car's anti-theft system. Most newer cards require a separate module to be installed to override the anti-theft system while the remote start is in use. Otherwise, when the anti-theft system detects an anomaly, it will immobilize the vehicle.
DEI makes a 556H module for this purpose. The link shows the instrall manual for this device.

Car won't start.Theft light blinks,clicking sound under hood and thumping like horn wants to go off.Seems like it's stuck in anti theft mode


anti theft light should blink every few seconds.

try disconnecting the battery for 15 minutes.

Anti-Theft-Perimeter The perimeter anti-theft system consists of the following components:
  • anti-theft indicator (THEFT)
  • remote anti-theft personality (RAP) module
  • hood switch
  • keyless entry remote transmitter
  • deck lid ajar switch
NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.
Up to four keyless entry remote transmitters (15K601) can be programmed at one time.
The keyless entry remote transmitters :
  • Are programmable.
  • Must be set at the same time.
  • House four buttons.
  • House three buttons (Mexico Anti-Theft System only).
Programming
Refer to Section 501-14B.
Inputs and Outputs
The remote anti-theft personality (RAP) module receives input from the following components for anti-theft operation:
  • Hood switch.
  • Deck lid ajar switch.
  • Keyless entry remote transmitter.
  • Power door lock switches (LH and RH).
  • Door courtesy input.
The RAP module distributes output to the following for the anti-theft system:
  • Power door unlock relay.
  • Power door lock relay.
  • Liftgate unlock relay (Wagon)
  • Park lamps relay.
  • HORN relay.
  • Dome lamp.
  • THEFT indicator.
  • Deck lid release.
Arming
The anti-theft system can be armed if:
  • The ignition switch is in the OFF position.
  • The panic alarm is off.
  • All doors are closed.
NOTE: If a door is open, the anti-theft system is prearmed and waiting for all the doors to be closed. The THEFT indicator will remain illuminated for up to 30 minutes waiting for all the doors to be closed. If a door remains open after 30 minutes, the THEFT indicator will turn off and the system will return to a disarmed state. After all doors are closed and the 30 second prearm (continuous THEFT indicator illumination) is complete, the system is armed.
NOTE: If the theft LED does not flash after 30 seconds, check the LED FLASH PID to see if the feature is enabled.
The anti-theft system will be armed when the lock button on the keyless entry remote transmitter is pressed, all doors are closed and 30 seconds have elapsed.
When the system is armed, the THEFT indicator will flash quickly until the system is triggered or disarmed.
Disarming
NOTE: Using a key in a door lock cylinder to unlock is not a valid method of disarming the anti-theft system.
Untriggered System
NOTE: If the driver arms the system and remains in the vehicle, an untriggered system can be disarmed by turning the ignition switch to the ON position.
An untriggered alarm system can be disarmed by pressing the unlock button on the keyless entry remote transmitter.
Triggered System
NOTE: If the hood or trunk are open when the system is armed, it must be closed and opened again before it can trigger an alarm.
An armed anti-theft system can be triggered by the following conditions:
The deck lid door, liftgate, hood or any door is opened using a key, inside door handle, hood release, etc.
  • The keyless entry remote transmitter can activate a panic alarm which is similar to the anti-theft alarm, but does not cause the THEFT indicator to flash.
A triggered alarm system can be disarmed by:
  • Pressing the unlock or panic button on the keyless entry remote transmitter.
  • Turning the ignition switch to the ON position.
Alarm State When Battery Power Is Cycled
When the RAP module is supplied power the first time at the vehicle assembly plant, the system will be in the disarmed state. The RAP module will remember whether it is armed, disarmed or triggered in its non-volatile memory. When the battery positive cable is removed and then reconnected, the system will return to the state it was in just before the battery was disconnected. If the system is in any prearm state, then the system will return to a disarmed state when the battery is disconnected and then reconnected.

Starting System
The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
------------------------------------------------------------------------------
The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed.
System Arming
The system will be armed by the remote entry transmitter when the following input sequence is followed:
  1. Turn the ignition switch off and remove the key.
  1. Close all doors (unlocked).
  1. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.
  1. Wait for the anti - theft warning lamp to turn off.
The system will also be armed when the following input sequence is followed:
  1. Turn the ignition switch off and remove the key.
  1. Open a door. Alarm warning lamp will flash.
  1. Lock doors with power door switches. Alarm warning lamp will now glow steadily.
  1. Close all doors.
  1. Wait for the anti - theft warning lamp to turn off.
Opening any door will activate the alarm after the alarm is armed.
Disarming an Untriggered System
The system can be disarmed by performing one of the following procedures.
  • Driver or RH front door is unlocked with a key.
  • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
  • If remaining in the vehicle, turn the ignition switch to ON or ACC position.
System Triggering
The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first.
Disarming a Triggered System
Carry out either of the following steps will disarm the triggered alarm system.
  • Driver or RH front door is unlocked with a key.
  • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.
--------------------------------------------------------------------
Passive Anti-Theft System (PATS)
The Passive Anti-Theft System (PATS), known as SecuriLock, 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 transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
The PATS functionality is incorporated within the powertrain control module.
PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized.
Anti-Theft Indicator
Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.

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 .

  • 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).

Anti-theft system stuck triggered


Anti-theft does not disable the lock cylinder itself it only keeps vehicle from starting,lock cylinder will still turn and energize the electronics. Sounds like you have a stuck tumbler in the lock cylinder itself,some times turning steering wheel with one hand while trying to turn the key with the other will free it up.
