bbfly OBD Lock bbfly-K02 OBD-II Port Protector — Aluminium Alloy & Reinforced ABS, Keyed Cylinder with 2 Keys

bbfly-K02 OBD Lock is a keyed protective cover that secures your vehicle’s OBD-II port with a coded cylinder and two matching keys.

The bbfly-K02 replaces screw-style OBD covers with a compact lock that blocks unauthorized access to your car’s diagnostic port. Built from aluminum alloy and reinforced ABS, this device resists forced removal and helps prevent thieves or unauthorized technicians from connecting to the OBD interface. Each unit uses an anti-theft key cylinder with a unique code and two keys, making it simple to secure and unlock the port without complex hardware or screwdrivers.

How does the bbfly-K02 physically protect my vehicle’s OBD port?

The K02 creates a barrier directly over the OBD-II connector so plug-in devices cannot reach the pins. Its metal and reinforced plastic construction is designed to withstand prying and blunt force, and the internal design makes removal without the proper key likely to damage pins or wiring.

• Aluminum alloy shell for impact resistance
• Reinforced ABS body to prevent bending or deformation
• Locks over the port to obstruct access to diagnostic pins
• Damaging removal required if key is unknown, deterring tampering

Will the K02 fit my car’s OBD-II port?

bbfly reports compatibility with approximately 95% of standard OBD-II ports, but port location and surrounding trim vary by make and model. Check the position and clearance around your OBD connector before ordering to confirm the lock will seat properly.

• Designed for typical OBD-II port sizes and shapes
• Not compatible if dashboard trim blocks the lock from seating
• Inspect port position and surrounding area prior to purchase
• Contact support with photos if uncertain about fit

How does the key cylinder work and how secure is the code?

Each K02 includes an integrated keyed cylinder with a single numerical code and two physical keys. The cylinder provides up to 10,000 possible blade variations, reducing the chance of accidental key matches and allowing you to remove the key only when the lock is fully engaged.

• One cylinder per unit, unique numerical code
• Two keys supplied with each lock for convenience
• Key can only be removed when the lock is fully in the locked position
• 10,000 possible cylinder variations for stronger uniqueness

What should I know about installation and everyday use?

Installation replaces screw-on covers by sliding the K02 over the OBD port and turning the key to lock. The product is made for straightforward operation, but if the key won’t eject, continue turning firmly to the OFF position and extract it once aligned.

• No screws or tools required—key-operated locking
• Insert over the port and turn key to engage
• If key resists removal, rotate fully to the OFF stop and pull
• Engineers addressed early slipping issues; patent pending

Who is this for? The bbfly-K02 OBD Lock is aimed at vehicle owners who want an easy, mechanical way to block unauthorized access to the OBD-II port—fleet managers, car collectors, ride-share drivers, and anyone concerned about data theft or illicit device installation. If you value a keyed physical barrier instead of screw-based covers and your vehicle’s port location allows a cover to seat correctly, the K02 is a practical, low-maintenance option.
