Automobiles have become indispensable in our daily lives, making them valuable assets that require adequate protection. Car theft remains a persistent issue, so car owners must safeguard their vehicles against potential thieves.

According to the Insurance Bureau of Canada (IBC), more than 86,000 vehicles are stolen across the country yearly.

Thankfully, technology has come a long way in providing innovative anti-theft devices that offer peace of mind and an added layer of security, helping to prevent stolen vehicles and protect high-target parts such as catalytic converters.

In this blog post, we will explore the top anti-theft devices for cars, empowering you to make informed decisions and protect your cherished ride, and help you get the cheapest car insurance.

What is an anti-theft device?

An anti-theft device is either preinstalled or an aftermarket feature that makes a vehicle harder to steal and easier to track or recover. Check your car’s manual or the manufacturer’s website to learn about the security features that can help prevent theft or assist in recovering a stolen vehicle.

There are two main types of devices – passive and active. Active devices need to be manually activated, such as a door lock, steering wheel locks, or an alarm system. Passive systems will monitor your vehicle 24/7, such as GPS programs.

Can anti-theft devices lower insurance?

As claims for theft continue to increase, you may wonder if these devices can help lower your Ontario car insurance. The good news is, it might.

To ensure you’re getting the most out of your anti-theft device, be sure to reach out to your coverage provider with proof of purchase and installation. Some companies offer incentives beyond immobilizers, and will offer savings for tracking systems. Some also offer a reduced deductible on the claim if your car is a victim of theft or thieves bypass the device.

Ask your insurer if there are any car insurance discounts for the type of device you have installed. Depending on your insurer and driving abstract, you’ll have various options.

The best anti-theft devices for Canadians

Now that you understand what an anti-theft device is and how your policy plays a role, here are the best options for your car.

Steering wheel locks

Steering wheel locks deter car theft by making it difficult for thieves to steer, even if they start the engine. They come in various designs, with foldable options for easy storage, and their bright colours and intimidating appearance discourage theft.

You’ll want to consider the material it is made of – steel is more difficult to cut or pry off than plastic. Some thieves may remove and replace the steering wheel with their own, so consider including additional devices or investing in a high-quality version.

Vehicle tracking systems

When a car is stolen or broken into, there is a risk of it not being found. With the help of programs like Tag vehicle tracking, they can help police recover vehicles. Some will monitor your car’s real-time location, while in motion or off.

Alarm systems

Car alarms are essential for vehicle security and have advanced features like motion and shock sensors, mobile apps, and GPS trackers. They produce loud sirens when triggered, such as window breaking or entering without the proper key, deterring potential thieves.

Not all vehicles have built-in alarm systems – if that is the case for your car, you may want to consider installing one professionally. Some come with mobile phone apps that can notify you if there is an incident.

Dash cams

Certain cams can record footage while the car is running or parked. Footage from a dash cam inside your vehicle can identify thieves or prevent it from happening in the first place.

Engine immobilizers

Engine immobilizers are electronic devices that prevent a car from starting without the correct key or transponder, making it almost impossible for someone to hot-wire the vehicle. Car manufacturers widely use them and provide an effective and hidden layer of security that discourages car thieves. Always double-check your vehicle make and model to ensure it is included.

Kill switches

Kill switches can prevent car theft by turning off specific circuits or systems in the vehicle, making it difficult for thieves to start the engine. They can be activated manually or remotely, providing extra security for your car. Installing a kill switch is an affordable and effective way to improve your car’s safety.

Do all new cars have anti-theft devices?

If you are buying a new car, most of them have anti-theft devices included, such as a factory alarm system or immobilizer. Many older cars lack the technology and devices that new cars do, so if you have an older car, consider adding additional anti-theft protection.

How do I know if my car has an anti-theft device installed?

Your vehicle’s manufacturing manual and website will include all the anti-theft devices. If you want to lower your policy costs, reach out to your insurer to see if there are any discounts on what is installed.
