Passive Alarm System: Enhance Your Car Security

As car theft rates continue to rise, it’s become crucial to invest in effective security measures for our vehicles. A passive alarm system serves as an invisible guardian, working seamlessly to deter thieves and enhance car security.

In this article, we will explore the benefits of a passive alarm system and how it effortlessly integrates into your vehicle's existing security features. So, let's delve into the features and advantages of a passive alarm system.

What Is The Passive Alarm System?

A passive alarm system, also known as a passive anti-theft system (PATS), is a type of car security system that automatically activates without any manual input from the user. The reason the alarm is referred to as a passive alarm is that the driver doesn't need to do anything to arm it.

A passive car alarm system works by automatically activating when the user leaves the vehicle and closes the doors. It relies on key recognition technology, where each key fob or electronic key contains a unique code programmed into the car's immobilizer system. If a valid key is not detected within a certain range, the system engages an immobilizer that prevents the engine from starting or running without the correct key or key code.

Note:
A non-passive alarm system refers to an active car alarm system. Unlike passive car alarm systems that automatically arm and disarm themselves, non-passive alarm systems require manual input or activation from the car owner. With a non-passive car alarm system, the owner must actively engage the alarm system by pressing a button or using a specific command to arm or disarm the alarm.

How Do I Know If My Car Has a Passive Alarm?

There are several indicators and characteristics you can look for to see if your car is equipped with a passive alarm system. Let's explore!

Check the owner’s manual

First of all, you need to check your owner's manual to see if your automobile has a passive alarm. Your vehicle's safety system type, including the type of alarm (passive or active), should be listed in the manual.

Check alarm control module

In cases where the user manual doesn’t specify, you can check for the existence of an alarm control module. Typically located beneath the steering column, the alarm control module often contains detailed information about the alarm system, providing valuable insights into whether your vehicle has a passive alarm system or not.

Check other features

There are several other signs that can suggest the presence of a passive alarm system in your vehicle. One indicator is a flashing light on the dashboard that activates when you lock the doors, signaling the activation of the alarm.

Additionally, you might notice a visible alarm sticker on the side window, designed to deter potential thieves and activated if a window is broken.

Once the passive alarm is triggered, the vehicle's doors will automatically secure, and the horn will initiate a continuous sound. If the system is integrated with an immobilizer, the engine will also be disabled until the vehicle is disarmed using the appropriate remote control.

All of the Anti-theft Devices for Cars Explained

Besides passive alarm systems and active alarm systems, there are several other anti-theft devices available for cars that can further enhance your vehicle's security. Here are the details:

GPS tracking devices

While a GPS tracker cannot guarantee the prevention of car theft, it provides the advantage of locating your vehicle if it is stolen. GPS trackers pinpoint your car's precise location on a digital map. In certain instances, they may even include a real-time anti-theft alarm feature.

Steering wheel lock

Steering wheel locks provide a significant challenge for would-be thieves due to their robust design. Removing a steering wheel lock requires skill and determination. However, you need to remember that steering wheel locks are not completely infallible.

Audible alarms

Audible alarms are designed to produce loud, attention-grabbing sounds when triggered, serving as a deterrent and alerting nearby individuals to potential theft.

Vehicle-tilt and glass-break sensors

When a glass-break sensor detects the distinctive sound frequency or vibrations of a window being broken, it can trigger an alarm, immobilize the vehicle's ignition system, or even send a notification to your smartphone. This alerts you to potential theft attempts.

Similarly, vehicle-tilt sensors are programmed to detect movements that suggest someone is tampering with the car, such as attempting to tow it away. If a significant change in the vehicle's position is detected, such as lifting or tilting, the sensor can activate an alarm, immobilize the ignition, or provide a notification to your smartphone.

Battery disconnect switches

Battery switches are installed in the vehicle's electrical system and allow you to easily disconnect the battery when the vehicle is not in use.

By flipping the switch to the "off" position, you effectively cut off the power supply from the battery to the car's electrical components. This prevents the engine from starting and renders the vehicle immobilized, making it difficult for thieves to hotwire or start the car.

Remote locks

Remote locks are a valuable anti-theft feature that provides convenience and enhanced security for your vehicle. With remote lock functionality, you can conveniently lock or unlock your car from your smartphone, even if you’re far away from it.

How to Disable Anti-theft System?

For some people, the sound produced by car alarm systems can be annoying, so they choose not to install one. Additionally, having knowledge of how to deactivate your car alarm system can be useful in case of malfunctions or unexpected issues.

Use Key fob

Using the key fob is typically the most straightforward method to deactivate the anti-theft system. By pressing the alarm button on the key fob, you can easily turn off the system.

Check the door lock cylinder

Sometimes, you might find that the anti-theft system is connected to the door lock system. So, you need to locate and activate a little switch or release lever on the door panel in order to turn it off.

Plug the key into the door

When the remote key starts to die, it might not disable the alarm. However, you should be able to use the regular key until you get home and replace the batteries in the remote key.

When you place the key in the driver's side door lock, turn the key and hold it in place for approximately 20 seconds, it should stop the alarm. This gives the vehicle time to recognize the key and ensure that the system is turned off. You can also try turning the key in the lock a few times to allow the system to recognize it.

Check fuses

If you’re looking for a quick fix tp stop the sound, you can remove the fuse. This will also provide a soft restart for the immobilizer.

You can normally find the alarm fuse in the panel. Check the owner's manual to find the exact location of the fuse used by the security system. When the fuse goes out, the car will not start, but you can pop it back in afterwards and reset the alarm.

Disconnect the battery

If all other attempts have failed to disable the anti-theft system, the next step is to disconnect the car battery. After keeping the battery unplugged for a few minutes, the computer system will reset. It’s important to wait a few minutes before reconnecting the battery. If the system has not reset and you’re still unable to bypass the anti-theft system, you’re going to need professional assistance.

Note:
Tampering with or disabling an anti-theft system without proper authorization is illegal in many jurisdictions. Engaging in such activities can result in legal consequences, including fines and even criminal charges.
