Main highlights

With an aluminium alloy housing and reinforced ABS, BBFLY OBD lock can prevent violent unlocking. Without a key with your code, the OBD lock cannot be disassembled without damaging the pins and wiring harness.

Other products available on the market are fastened with screws. BBFLY OBD2 lock only needs one key to lock and unlock the OBD port.

BBFLY OBDII lock perfectly replaces the screw lock by using a key and integrated key cylinder. Screw locking has obvious defects such as complex installation and disassembly and high probability of being unlocked by small tools.

**Superior Build Quality and Durability**: Weighing in at a robust 130 grams, our OBD lock is significantly heavier and more solidly constructed than competing products. Made from high-grade materials, it withstands tampering attempts far better than lightweight alternatives fixed with vulnerable screws. This added weight and sturdiness ensure long-lasting performance, giving you peace of mind that your vehicle is safeguarded against sophisticated theft techniques.

**Proven Vulnerability Protection Over Competitors**: While other OBD locks on the market use screw-based fixation methods—often disguised as unique anti-theft screws—these can be easily defeated with simple tools like tweezers or pliers. Our innovative key-operated system eliminates this flaw entirely, offering a true mechanical barrier that thieves can't bypass without the matching key. This makes our product a superior choice for preventing key cloning and vehicle theft.

**Advanced Key-Lock Mechanism for Ultimate Security**: Our OBD lock features a high-precision internal lock cylinder with 10,000 unique blade variations and corresponding key codes. This ensures that each lock has its own distinct key that cannot be interchanged with others, providing unparalleled protection against unauthorized access. Unlike competitors' products that rely on easily bypassed anti-theft screws, our design requires a physical key to unlock, making it virtually impossible for thieves to connect electronic devices to your vehicle's OBD port and clone keys.
