What Is the Karr Car Alarm?
Definition and Purpose
The karr car alarm is a security add-on offered via dealerships in the U.S., designed to augment factory alarm systems. It includes sensors like shock detection, immobilization, remote access, and sometimes GPS tracking—all meant to deter theft or unauthorized access.
Key Features of the Karr Car Alarm
Enhanced Detection and Immobilizer
This alarm installs motion, shock, and door sensors to detect manipulation or forced entry. It often integrates with engine immobilization to prevent theft
Remote Control and App Connectivity

Insurance and Resale Benefits
