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).

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.

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.
