bbfly

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

bbfly

CA$69.90

More Details
Main highlights
- 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).
- 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.
- 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.
- 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.
- 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.

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

bbfly

CA$96.67

More Details
Main highlights
- 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.
- 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.
- Our structural engineers have solved the easy slip of early products for some vehicle models. Now, the patent application is under progress.
- Other products available on the market are fixed with screws. BBFLY OBD2 lock needs a key only to lock and unlock the OBD port.
- 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.
- 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.
- 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.
