GM DELCO THEFTLOCK RADIO UNLOCK CODE:
1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down.
2. After doing step one and writing down the code, immediately press
the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over).
3. Call this number, it's a prerecorded message, so don't worry about
having to talk to anyone...1-800-537-5140. The voice will ask if
you're
calling for Chevy, Pontiac, Cadillac, etc... When you here him tell
you
to press "2" for Pontiac, press 206010 and hit the # key. He'll ask
you
for the 6 digit code that you've written down. Enter that and press
the
* key. He will then give you a code, and the option to get additional
4
digit codes, but one should be sufficient.
4. Follow the normal procedure in your owners manual for unlocking the
radio with your new code...press the hour set button on your radio
until
you get the first two numbers of the code, then press the minute set
button until you've entered the last two numbers. Immediately press
the
AM/FM button once the correct code is entered and the code SEC or
"secured" will be displayed on the display screen. Now, just turn the
radio on, and your ready to roll.
There is an additional step you can take to remove all codes from the
radio and start from scratch by entering your own personalized 4 digit
code so that it won't get you in a pickle again! Just repeat step 4
and
you should get a display screen that reads ---. This means the code is
out, and you can now program your own code. Of course, once you
receive
the 4 digit code from the GM recorded message, just keep it in a safe
place, because you can use that same code again and again should you
have any more problems with it in the future. Good luck, and yes, it
does work.

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.

Just bought a used truck it is a 1995 full size chevrolet it has a theft lock radio but does not work,the radio will not show any display not loc r lock there is a button u push it will show u the time...


If the clock will display for a few seconds that means it,(the clock) has power, and perhaps the entire unit. However, if the anti-theft is engaged, a dealer will be in your future. It will take them about a minute to un-lock the radio, or they will know if the radio no longer works.

This is the anti theft function working as it should. Your husband needed to override it with the key. The command told the car to lock down. Because the key was not in the car the anti theft set off the alarm and locked down the engine as well.
This is exactly what you would want the car to do if you left it locked on the street with your windows down while shopping. Otherwise someone could reach in the window, unlock the door, slide in and start hot wiring the car.
These lock functions are programmable and can be changed at the dealership.

How to remove or bypass the factory installed anti theft vehicle immobilizer.


in the 1996 sunfire GM uses an anti theft lock system. It can be triggered by all sorts of things. In order to relinquish this you must have a key to turn the ignition. These are not coded just plain cut keys. Once you attain this you put the key in and turn the ignition to the ACC position and wait ten minutes (theft lock light will turn off), turn off and take key out. You MUST do this 3 times and then the theft lock will be disarmed.

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).

Car won't start


Hi, does the alarm shut off when you unlock the passenger door?
If it does not I will give you a test that you can do.
1. disconnect the harness anti-theft control module. (loctaion depend were you live USA next to fuse panel Canadian models above the glove box.) Check the continuity between Light Green/Black wire and Black wire of the anti-theft control module.
2. Continuity should not be there with the door lock in, lock or neutral position. With the door lock in-between lock and neutral position (any door) continuity should be present.
3. If continuity is as specified replace the anti-theft control module. If continuity is not as specified, check operation of the door lock switches.I will add that test at bottom.
4. If the door lock switches are ok check the continuity og LIGHT/BLACK wires between anti-theft control module and door lock switches. Check Continuity of BLACK wire between door lock switches and ground. Continuity should be present if Continuity is not present repair harness or connectors.
5. If Continuity is present, check continuity LIGHT GREEN and BLACK wire of anti-theft control module. Continuity should not be present with trunk lock in lock or neutral position. With trunk lock in-between lock and neutral position, Continuity should be present.
6. If Continuity is as specified replace anti-theft control module. If Continuity is not as specified, check operation of truck lock switches. If necessary replace trunk lock switch.
7. If trunk lock switch is ok, check Continuity og LIGHT GREEN wire between anti-theft control module and trunk lock switch. Check Continuity of BLACK wire between trunk lock switch and ground. Continuity should be present. If Continuity is not present repair harness or connectors.

DOOR LOCK SWITCHES
Disconnect 4-pin door lock switch connect (left and right front doors) With door lock in neutral, full lock or full unlock position, there should be no continuity between any terminal and BLACK wire terminal. Continuity should exist between LIGHT GREEN?WHITE wire and BLACK wire terminals with door lock in-between neutral and full lock position. Continuity should exist between LIGHT GREEN/BLACK wire and BLACK wire terminals with door lock in-between neutral and full unlock positions. If continuity is not as described, replaced door lock switch.

Hope this help its a place to start. let me know if you need anything else.

Cheers
