Why It Matters (The Problem & The Solution)
Car theft has hit crisis levels, costing over $20 billion annually across North America. Thieves now use digital devices to clone keys or bypass your push-to-start.
While most products track your car after it’s stolen, KēZ prevents theft from happening in the first place by immobilizing your engine at the source.
