Sounds like the Body Control Module is having issues. You can try pulling the negative battery cable for 10 mins to reset it. But most likely you will need to go to a dealer and have it either flashed (reprogramed) or replaced.

How to set & cancel theft deterrent system or how to set & cancel security...

Theft deterrent system (on some models)

Theft deterrent system is designed to deter vehicle theft. The system flashes the turn signal lights and turns on the interior light or the signal lights only (depending on the model), and sounds security horn and vehicle horn when it detects abnormalities such as follows:

• Any door or hood is forcibly opened.
• The batter terminal is disconnected and then reconnected
• The system control is disconnected and then reconnected.
• Abnormal impact is detected when the impact sensor function is on.

The system flashes the turn signal lights and turns the interior light or the signal lights only (depending on the model), and sounds security horn and vehicle horn if someone attempts to damage or break into your car.

Setting the system

You can set the system with or without the impact sensor function. For details, see "Canceling the impact sensor" below.

1. Turn the ignition key to "LOCK" and remove it.
2. Have all passengers get out of the vehicle
3. Push the lock (set) switch on the wireless remote control key once. At this time, the turn signal lights flashes once and the security indicator light comes on.

The system is set after 30 seconds. At this time, the security indicator light start flashing slowly.

Once the system is set, you cannot start the engine until you cancel the system.

The system will not be set in the following cases.

• When any of the door is open; security horn sounds for 1 second, close the door and set the system again.
• When the hood is open; close the hood securely.

Canceling the Impact Sensor

The impact sensor can be cancelled to prevent false alarms from being triggered incase of the following conditions:

• When parked in the noisy area
• The vehicle body or glass is subjected to a strong impact from the (such as in highly pressurized car wash).
• When transporting by a car carrier or ferry.

To cancel the impact sensor;

1. Lock the door by pushing the lock (set) switch on the wireless remote control key once, and turn signal light flash once
2. Then push the lock (set) switch twice within 5 seconds. At this time, the turn signal flash 5 times to indicate the impact sensor function is disable.

The impact sensor is deactivated as long as the system remained armed.

Canceling the system

The system will be cancelled by the following two ways:

• Turn the ignition key from "LOCK" to "ON" position.
• Unlock any of the doors by pushing the unlock (cancel) switch

If the turn signal lights flash 3 times, the system has been alarmed. Check to see if there is any abnormality with your vehicle.

If any of the doors is not opened within 30 seconds, all doors will be automatically locked and the system will be set.

When the system is set

Activating the system; When the system detects abnormalities such as follows, it flashes the turn signal lights and turns on the interior light or the turn lights only (depending on the model) and sounds the security horn and vehicle horn of 30 seconds.

• Unlocking any door without using wireless control
• Any door or hood is forcibly opened.
• The battery terminal is disconnected and then reconnected.
• The system control assembly is disconnected and then reconnected
• Abnormal impact is detected when the impact sensor function is on.

Reactivating the alarm;

Once set, the system automatically resets the alarm after the alarm stops.

The alarm will activate again under the same circumstances described in "Activating the system".

Stopping the Alarm

The alarm will be stopped by the following two ways;

• Turn the ignition key from the "LOCK" to "ON" position.
• Unlock any of the doors by pushing the unlock (cancel) switch.

The system can be cancelled by these ways at the same time.

If the battery becomes discharged due to the vehicle being unused, for a long time etc., when the battery is recharged or replaced, the system will activate the alarm. If this happens, immediately unlock any of the doors by pushing the unlock (cancel) switch, and the alarm will stop.

Testing the system

1. Set the system
2. Insert a wireless remote control key into the key hole on the driver's door handle, and unlock the door.
3. Open the door, and an alarm will sound.
4. Stop the alarm by pushing the unlock (cancel) switch.
5. Repeat this operation for the front passenger's door.

Good luck.

I have a 98 Nissan altima gxe and my alarm won't honk when I lock the car but the lights go off when I lock it and Wen I take the alarm off no honk or lights go off Wat can I do

holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.

2004 Olds Silhouette - electric door locks lock on their own

Most likely your alarm system needs reset. When you use the button to turn the alarm on and off the horn beeps and lights flash. Horn beep when switch turned on, makes sense would be in the alarm system with all you've told.

Automatic door locks will not work

Probably the door actuator - a part inside the door that activates the lock, particularly if neither the interior lock switch or the remote do not lock the door.  Once the doors lock the horn will beep again - the lack of beep indicates the vehicle is not secure.

Door lock 2004 jetta wagen

If remote locks and unlocks driver door but does not unlock passenger doors,then follow the advice above:
Get in the car using the key to unlock the doors. From the passenger side lock and unlock your doors using the button on the passenger door. Get out and the remote should now unlock all the doors with 2 presses.
Worked perfectly for me after several other suggestions (and dealer) failed.
