Car insurance and anti-theft devices: what to know
Anti-theft devices installed in your vehicle are good for more than preventing theft: they may save you money in car insurance premiums. This popular discount opportunity is available from many top auto insurance companies.
Let’s explore the various types of anti-theft devices, their benefits and why car insurance companies encourage their clients to use them.
Why anti-theft devices impact car insurance rates
It’s simple — if your car gets stolen, your insurance company is on the hook to replace it. Car insurance companies advise installing anti-theft devices in your vehicle to thwart thieves from stealing your car and in turn, avoid paying out the cost of your loss.
Insurers encourage the implementation of these devices by offering discounts to drivers with one or more theft-prevention technology. Twelve U.S. states require insurance companies to offer anti-theft device discounts to policyholders with comprehensive coverage.
Does car insurance cover auto theft?
If you don’t opt for comprehensive coverage, your insurer will not replace your stolen vehicle.
Types of anti-theft devices
There are many types of theft-prevention devices available today that will earn you a discount from your insurance provider. Read on to find examples of manual, automatic and remote disabling devices, as well as other ways you can protect your vehicle from theft.
Manual disabling devices
Sometimes referred to as active devices, manual disabling devices must be physically switched on by the driver.
Common active devices include:
- Steering wheel lock: This device immobilizes your steering wheel, delaying and often preventing theft completely by ensuring a lack of movement.
- Brake lock: This lock makes it impossible to push down on the gas pedal and drive away until disabled.
- Kill switch: This option requires installation (either by yourself or professionally), but the kill switch disables all electricity in the vehicle, rendering it undrivable until turned off by the owner.
Automatic disabling devices
Automatic devices are also known as passive devices and work without manual enabling from the driver. Many new cars have these already installed. Examples of passive devices are as follows:
- Transponder keys: Transponder keys must be in the vehicle in order for it to be driven. Without it, cars cannot be hot-wired nor can thieves break the ignition lock. They provide a higher level of security for vehicles — in fact, a 2015 study found that transponder keys decreased car thefts by 40% between 1995 and 2008.
- Audible alarms: Most cars are equipped with an alarm system that blares loudly when it detects unwarranted touch. If your car does not have this installed already, you can purchase one separately. It’s important to note, though, that alarm systems are sensitive and go off easily, and passersby hear car alarms so frequently nowadays that it is not the most effective way to prevent theft.
Remote disabling systems
A newer addition to anti-theft devices are remote disabling systems. These devices connect to your smartphone and allow you to decelerate, downshift or lock the brakes.
These are often expensive and are more commonly used in commercial vehicles than personal cars.
Vehicle tracking systems
These devices are used when cars have already been stolen. They are meant to provide the location of your vehicle via a GPS system and deliver the information to your smartphone. There are a few services that offer this technology:
- GPS trackers: With this device in your vehicle, you are able to track your car whenever it’s in motion. With some models, you can get alerts sent to you via email or text message. Car thieves may be deterred from stealing your vehicle if they see a GPS device within it.
- Subscription services: The most popular example of this is OnStar, which tracks your vehicle’s location and can also remotely prevent the engine from starting when a theft has been reported. Users pay a minimum of $25 per month for this service.
- Vehicle recovery systems: The best-known example of these is LoJack, which uses radiofrequency to locate your car if it has been stolen. The transmitter that remains in your vehicle is designed to help police find your car when it's stolen, and will send you an alert via text, email or phone call if your car is being driven without the corresponding LoJack keyfob inside. While there is a 90% recovery rate with this device, it is very expensive.

|Passive disabling device||$1,472||-0.75%|
Auto insurance data methodology
The auto insurance rates published in this guide are based on the results of The Zebra's State of Insurance car insurance pricing analysis. This analysis of more than 83 million insurance rates spans every U.S. ZIP code, using a sample user profile: a 30-year-old single male driver with a Honda Accord, good credit and full coverage at these levels:
- $50,000 per person/$100,000 per incident for bodily injury liability
- $50,000 per incident for property damage liability
- $500 deductibles for collision and comprehensive coverage
To generate pricing for particular rating factors, we adjusted the driving profile based on common pricing factors used by major car insurance companies. These factors include credit score, coverage level, driving record and others.
In some instances, average rates from Liberty Mutual were derived from internally sourced sales data.
