How Anti-Theft Systems Work?

Anti-theft systems work like a body’s immune system which means that if the body recognizes any unusual entry such as viruses into the body, the body’s defense system reacts against them. In the same way, the anti-theft system of the vehicle activates if it detects any unusual activity to the vehicle such as theft. Like the body’s defense, the anti-theft system of the vehicle works in various ways, some common of them are:

• Immobilization System: Immobilizers in the anti-theft systems disable the engine and fuel system of the car if unusual activity is detected, such as an incorrect transponder key.
• GPS Tracking: The location of stolen vehicles can be tracked using GPS technology in advanced anti-theft systems to recover the vehicle. GPS tracker provides real-time data about the car’s location.
• Alarms: The car alarm will engage through the notification system if abnormal vibrations are detected after an unauthorized entry attempt has been made through an improper key or even breaking a window.
• Steering Lock: Steering Wheel locks as a matter of security when an incorrect key is detected..
• Kill Switch: Some vehicles cut off the power to the ignition system or fuel pump as an anti-theft mode.
• Interior Sensors: Along with these exterior sensors, interior sensors detect unusual activity inside the vehicle and trigger alarms to prevent theft.
• Keyless Entry System: There is a specific code sent from the key fob to the automobile computer for verification. If the vehicle perceives it as the incorrect signal, it will be locked.

Common Problems Related to Anti-theft System

The anti-theft system of the car may trigger due to various reasons including:

• Faulty key

Preventive Measures to Avoid Anti-Theft Mode

Here are some preventive measures to avoid anti-theft mode:

1. Always use the right key fob to start the car.
2. Ensure the key fob battery works properly and should be replaced immediately when dead.
3. Do not mess with the ignition system or the security-related part.

How to TroubleshootAnti-Theft System Issues?

You can troubleshoot anti-theft issues on your own without the assistance of any professional help. Here is how you can do so:

• Use the spare key

Sometimes, the vehicle system fails to identify the chip in the primary key because it wears out with time. Therefore, it is advisable to use an alternative key to bypass the malfunction of the original key. There is also a chance that the fob battery of the primary key is weak. So, it would be appropriate to test the spare key.

• Disconnect the Car battery

Another significant cause in debugging the anti-theft problem is the removal of the car battery. For this, first, open the bonnet of your car, find the battery, then remove the negative terminal of the battery, and turn the key to the ignition position. Now, keeping the ignition ON, press the driver’s door open and reconnect the negative terminal after 15 to 20 minutes. It will discharge the battery and deactivate the anti-theft system without causing an alarm. You can remove the key from the ignition to start your ride. However, if this troubleshooting does not work, the battery is probably dead; try replacing it to see if it works.

• Reset the Anti-theft System

You can reset the anti-theft system manually by turning your vehicle on after inserting the key. Wait for 10-15 minutes and again turn it off. Now again wait for 30 seconds and later turn on the key. Repeat this cycle 3 times to reset the connection between the computer and the key.

• Check the Fuse Box

Locate the fuse by checking the vehicle’s manual and replace it if it has blown. Hence, you are advised to carry the spare fuses.

How to Get Your Car Out of Anti-Theft Mode with a Key?

Bypassing the anti-theft system is not a walk in the park, as it has a complicated software because if it were an easy process, thieves and criminals could easily steal your car. But still, some ways can be implemented to get your car out of anti-theft mode with a key which are:

1. Method of Emergency Key Override

Regular maintenance of the car prevents your vehicle’s anti-theft issues. Routine maintenance and check-ups of electrical sensors and other electrical issues avoid problems with anti-theft systems. So, you are advised to check your vehicle regularly for battery health, wiring, and other electrical components.

• Check the Key Fob Battery

A dead or weak key fob battery can usually activate the anti-theft mode. Ensure that the key fob’s battery is functioning well to avoid these situations. If the battery of the key fob is running low, it will not be able to signal your car’s anti-theft system. Hence, change the battery in your vehicle’s key fob if it’s dead.

• Door Lock Cylinder Check

Another damaged part that can lead to the malfunctioning of a car anti-theft system is the damaged lock cylinder of the door. If the car’s sensors detect any irregularity with the door lock, the anti-theft mode of the car will be activated. So, inspecting any damage in the lock cylinder is better to get your vehicle out of the anti-theft mode.
