bbfly

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

bbfly

CA$85.15

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.
- 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.
- 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.
