OBD Lock, bbfly-K02 ODB Port Locking Tool, Car OBD2 Protector Device (K02)

Why we love it

Easy key-based locking mechanism.
Durable materials prevent theft.
Wide compatibility with vehicles.

Main Highlights

BBFLY OBDII lock perfectly replaces screw locking by using a key and an integrated key cylinder. Screw locking has apparent defects, such as complex installation and disassembling and high probability of being unlocked by small tools.
Other products available on the market are fixed with screws. BBFLY OBD2 lock needs a key only to lock and unlock the OBD port.
With an aluminum alloy shell and reinforced ABS, BBFLY OBD lock can prevent violent unlocking. Without a key with your code, the OBD lock cannot be dismantled without damaging the pins and wiring harness.
bbfly-K02 OBD lock is equipped with an integrated anti-theft key cylinder, and each key cylinder has a sole digital code and two keys. The cylinder blade can have 10,000 variations.
BBFLY OBD2 locking is applicable to 95% of OBD ports. However, the peripheral structures and positions of OBD2 ports for vehicles of different brands and models vary. Please check whether the position of your OBDII port matches the product before purchasing.
K02 can only pull out the key when it is completely locked. If it is found that the key cannot be pulled out, please continue to turn it to a fixed position in the “OFF” direction forcefully, and then the key can be pulled out.
Our structural engineers have solved the easy slip of early products for some vehicle models. Now, the patent application is under progress.

Main Highlights

【Block the Thief's Shortcut】Worried about modern theft tools? This OBD2 lock is built with solid alloy (not weak 3D-printed plastic) and unique, non-standard security screws.

This OBD2 lock anti-theft device seals it shut, physically eliminating the risk of key cloning or ECU tampering, ensuring you retain absolute control and peace of mind in any situation.
【Quick & Simple Installation】We include step-by-step instructions with clear illustrations. Just a few simple steps with the included tool are all it takes for a secure install. Designed for easy removal when you need it, and comes with a dedicated keychain for storing the security screws, offering a complete organizational solution.

OBD2 Port Anti-Theft Tool, OBD Lock Protector with Key

Why we love it

Ultimate security against theft.
Superior durability for long-lasting use.
Effortless installation without tools.

Main Highlights

**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.
**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.
**Effortless Plug-and-Play Installation**: No tools or professional installation required! Simply insert the lock into your vehicle's OBD port and turn the key to secure it in place. This user-friendly design allows you to quickly open or close the OBD port as needed, offering convenience without compromising security. It's perfect for everyday drivers who want hassle-free protection against vehicle theft.
**Universal Compatibility with Considerations for Fit**: Designed to fit most standard OBD ports, our lock provides broad compatibility across various vehicle makes and models. However, due to variations in OBD port locations and surrounding plastic encasings in some vehicles, the larger size of our lock may require checking for fitment. In certain models, it might protrude slightly and could come into contact with the driver's leg—please verify compatibility with your specific vehicle to ensure optimal use.
