4/5 stars for dry-weather vendors. 2/5 stars for rain or coastal wind use.
Release the mechanical latches located at the top of the windshield frame.
Uses interior sensors to detect movement inside the cabin (crucial if your car windows are broken).
The hazard lights will flash twice, and the siren will chirp twice to let you know the system is disarmed.
Replace your key fob battery first. Check that all doors and the trunk are securely shut.
