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.
