Common Causes Why does your car alarm go off automatically and what to do

The alarm system is an essential part of your car. After all, it is meant to protect your car from any crime related problems. However, not many people know about the basic principles behind your car’s warning. These sensors include car door sensors, impact/collision sensors, proximity sensors, tilt sensors, and even microphone sensors. Of course, older car models use fewer sensors than modern cars. So whenever any of these sensors fail, it can cause it to behave randomly and give false alarms. That’s why we are going to give you the most common reasons why you might face this problem.
- Weak or dead car battery
- Corrosion or rusted battery terminals
- Broken key fob
- Roof latch sensor dirty
- Poor connection to the control unit
- The alarm is set incorrectly
- Sensitive shock sensor

As one of the most common reasons why a car can fail, a low battery could be the culprit causing your alarm to go on at random times. That’s why car owners must know the condition of their car’s battery. Normally, your battery sends a signal whenever you start the engine. If your battery is running low, the alarm will sound whenever you turn on the car. Think of it as the car that tells you it’s time for a replacement.

That way you can have enough charge to put it in the safest location and replace it. Plus, you can always call emergency roadside assistance in case you get stuck somewhere.
Corrosion or rusted battery connector
Provided your battery is sufficiently charged, consider checking the battery terminals. If your battery has rusted terminals, it can trigger an alarm by sending a low battery signal to the system. If the terminals are a bit rusty, you can fix them yourself by cleaning them. Before proceeding, however, be sure to disconnect the battery and put on safety clothing. Feel free to use a quality battery cleaner to remove corrosion, while ensuring that your battery is not exposed for extended periods of time to any grease.
Key fob is broken
Whenever your car remote control fails, it can cause your car alarm to sound randomly. After all, the remote control, or key, has a connection to the alarm system. Since this remote works by sending a signal to your car, a broken remote can send false alarms. You can also scan your remote with a code reader.
Dirty suction latch sensor
Next, another common reason that might trigger your alarm is the latch sensor of the hood. A latch of the hood helps to close and lock. When you open your hood, the sensor turns off and lights up a warning sign on your dashboard. In case it is closed, then the switch will turn on. This switch can also tell you when the hood isn’t closed properly. However, if it has enough dirt around, it can trigger an alarm at any time. First, you need to make sure that the negative terminal of the battery is disconnected. Then locate your hood latch sensor. It should be behind the hood latch, near the headlights. Spray a little detergent and use a brush to scrub gently. Finally, use a cloth to completely remove any fine dust that may be present.
Poor connection to the control unit
If you’ve cleaned the hood and the warning still randomly fires, another possible cause is a poor connection to the car’s main control unit. In some cases, that can mean more than just your hood latch is in danger. If this is your situation, you may see other false readings, such as false airbag lights. Try disconnecting and reconnecting the sensor to see if that helps. If not, consider taking your car to a professional.
An incorrectly set warning
In some cases, car owners may experience this problem because the alarm is not set in the first place. This situation often occurs when people buy themselves a new car or an alarm system.
Sensitive shock sensor
Finally, when a car alarms randomly, it may be due to the sensitive shock sensor. The job of these sensors is to detect any impact your vehicle is receiving. Just like the roof latch sensor, it can notify you whenever something bad happens to your car. This problem can even cause your battery to run out of battery earlier than usual. If your alarms go off, you should try adjusting them again. You can find these sensors under the dashboard in a small control box out of sight. Configure them by turning the dial on the box. You can always refer to your owner’s manual whenever you find yourself stuck in a rut. That way, a professional can pinpoint the exact cause of this type of problem.
