Anti-Theft Device DiscountAuto
Because comprehensive coverage pays for theft, insurers discount it when your vehicle is harder to steal or easier to recover. The savings are modest but automatic once documented.
Anti-theft discounts apply to the comprehensive portion of your policy — the part that pays if your car is stolen or vandalized. Factory or aftermarket alarms, engine immobilizers, VIN etching, and stolen-vehicle recovery systems all reduce theft risk, so insurers reward them.
Many newer vehicles include qualifying anti-theft technology from the factory, and the credit may already be applied. Higher-theft vehicles and higher-theft areas tend to see the largest benefit.
What qualifies and how it applies
The discount reduces your comprehensive premium (not liability). Passive devices that activate automatically — factory immobilizers, alarms — usually earn more than manual devices. Recovery systems that help police locate a stolen car can qualify for an additional credit. Keep documentation of any aftermarket install.
- •Applies to comprehensive coverage only
- •Passive/automatic systems (immobilizers, alarms) qualify best
- •Recovery/tracking systems may add a further credit

Anti-Theft Device Discount — Frequently Asked Questions
Do car alarms lower insurance?
+
They can lower the comprehensive portion of your premium, because comprehensive covers theft and vandalism. Passive systems that arm automatically — factory immobilizers and alarms — generally earn more than manual ones, and recovery systems that help locate a stolen car may add a further credit. The discount only applies if you carry comprehensive coverage.
Does my new car already have the discount?
+
Possibly. Many newer vehicles include qualifying anti-theft technology from the factory, and insurers may apply the credit automatically based on the VIN. It's still worth confirming with your insurer that any factory or aftermarket system is reflected on your policy, especially on higher-theft models where the benefit is largest.
