Main highlights

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.

Other products available on the market are fixed with screws. BBFLY OBD2 lock needs a key only to lock and unlock the OBD port.

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.
