What is anti-theft discount?

An anti-theft discount is a premium reduction an insurer may offer for an eligible factory-installed or approved vehicle security device.

Also called: vehicle security discount

Glossary date: July 6, 2026

How it works

Qualifying equipment and affected coverages vary. A device may reduce the comprehensive premium without changing liability or collision cost.

Example

A vehicle has a qualifying tracking and recovery system. The insurer applies a discount to the coverage associated with theft risk.

Why it matters

The advertised percentage may apply to only a small part of the total premium.

What to check on your policy

Confirm the device code, proof required, affected coverage, discount amount, and whether the insurer already included it.
