This innovative new accessory adds a powerful layer of protection by securing your car’s OBD2 port—the gateway many thieves use in modern vehicle thefts. At the same time, it discreetly conceals your CarLock device for a clean, low-profile install. This upgrade is tailored to help keep your car safe and your setup sleek.
Why the Mixer/Demixer Cable Is a Must-Have
With this next-level security enhancement, you’ll be able to:
