Protect your vehicle from the fastest-growing auto theft method with our premium OBD II Port Anti-Theft Lock.
Modern thieves can access your car's OBD II port in seconds, rewrite your vehicle's ECU code, and drive away with your car without a key. Our OBD security lock creates a physical barrier between thieves and your car's most vulnerable access point, with an exclusive T20 torx security system that can only be removed with the included matching tool.
Engineered for North American vehicles, our OBD port lock is fully compliant with the SAE J1962 OBD II standard, fitting 99% of 1996 and newer cars, trucks, and SUVs. The heavy-duty aluminum construction resists prying, breaking, and corrosion, outperforming flimsy plastic alternatives on the market.
Installation takes less than 60 seconds with no modifications required. The kit includes 2 replacement T20 torx bits and a compact keychain handle, so you can quickly remove the lock for dealer service, diagnostics, or maintenance without hassle.
Whether you're a personal car owner, fleet manager, or rental car operator, our OBD II port lock delivers simple, effective, and affordable protection against OBD-related vehicle theft, tampering, and data breaches.
