What is causing the anti-theft alarm light flashing/horn blowing go off?


the remote key would be the easiest (and cheapest) thing to try first but i don't think that a low battery in the fob would activate the alarm randomly , i'd get the OBD codes read as will point to which part of the anti theft/central locking system is causing the issue

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.

First: alarm went off on its own.(mazda 6 2003). Now when locking and unlocking car sometimes indicators flash and sometimes not. Now red immobaliser light is flashing on dash when driving, then stops...


there is often a small back up battery in the immobiliser unit itself, if you can locate this unit and replace the battery with the ignition on / engine running, then it should not need recoding and work fine after that. The other thing that could be wrong is the key battery (if the fob has one) or the transponder chip in the key head. If the key signal is low the immobiliser lamp will light during driving, but this does not explain the alarm going off. That is more likely either a poor vehicle battery, alarm / immobiliser back up battery, or another electrical fault such as water leakage into a tail-light or even the alarm unit itself when it rains. A lot of alarms are voltage sensing and when the vehicle is parked they will alarm if the battery voltage changes for any reason, though not during driving so the battery in the immob is my first choice to look at.

Go inside the vehicle,dont put key in ignition, leave driver's door open, press the auto lock button on the driver's door, now close door while you are inside and watch on the dash the alarm enable itself, once it stops flashing open the door, this will set off the alarm, lights flashing horn blowing. Now take the key and put it in the drivers door and turn the key to stop the alarm. Now start you vehicle. If you want you can take the glove box apart to get to the vehicle security module to remove it. Dont unplug it unless the vehicle is running (must be running due to back up on computer) unplug the module and you will never have another problem with the security again and it does not effect your powerlocks.
