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

Main Highlights

  • 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.
  • Other products available on the market are fastened with screws. BBFLY OBD2 lock only needs one key to lock and unlock the OBD port.
  • 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.
  • bbfly -K02 OBD lock is equipped with an integrated anti-theft key cylinder, and each key cylinder has a single 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 makes and models vary. Please check if the position of your OBDII port matches the product before purchasing.
  • K02 can only pull out the key when it is fully locked. If it is found that the key cannot be pulled out, please continue to rotate it to a fixed position in the "OFF" direction, and then the key can be pulled out.
  • Our structural engineers have solved the slight slipping of early products on some vehicle models. Now patent application is underway.

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

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.

bbfly-K01 OBD2 Lock, OBD Port Lock Anti-Theft Device, Car Anti-Theft OBDII Locking Device

Main Highlights

  • Currently, other products available on the market are fixed with screws. As a result, all types of screws can be easily unscrewed by thieves by using several different tools, and the interchangeability of these products is extremely high.
  • It’s not required to assemble bbfly K01. The OBD2 port can be instantly unlocked or locked by using a key to turn the key cylinder only.
  • bbfly-K01 is combined with aluminum alloy and POM. The S-shaped double groove cylinder technology can prevent technical unlocking (master keys or crowbars), while the aluminum alloy can prevent violent unlocking (with tools like a hammer).
  • Equipped with a double groove blade cylinder, bbfly K01 has a complex interior structure, and the cylinder blade can have over 10,000 variations. One key matches one key cylinder only, and each cylinder has one sole number. Therefore, the interchangeability is close to zero.
  • bbfly-K01 is applicable to 90% car OBD ports. Because of the authentic key cylinder and anti-theft structure, K01 is larger and heavier than other products. Please check whether your OBDII port matches the product before purchasing.
  • Repeatedly designed and tested by our structural engineers, volume production and sales of bbfly-K01 have been made in 2025. The patent application is under progress.
  • 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.
