Why You Need It

Modern vehicle theft has gone digital. High-tech car thieves no longer need your keys to target your car — in many cases, they attempt to access the vehicle’s OBD2 diagnostic port to clone keys, reprogram fobs, or interfere with the engine control system.

The Universal OBD2 Anti-Theft Lock Cap – Keyless Security Cover adds a strong physical barrier over your vehicle’s OBD2 port, helping stop unauthorised access before it begins. Built from aluminium and stainless steel, this keyless lock cap is designed to enclose the diagnostic port and make fast plug-in attacks far more difficult.

Instead of relying on a traditional key cylinder, this model uses tamper-resistant security screws and concealed cover stickers to create a discreet, secure, fit-and-forget layer of protection. Once installed, it helps block one of the most common physical access points used in digital vehicle theft.

It is a simple, low-profile security upgrade for everyday drivers, commercial vehicles, 4WDs, work utes, and fleet operators who want extra protection without adding another key to carry.

Installation Guide

Step 1: Select the Right Bracket

Begin by selecting the correct mounting bracket for your vehicle. Start with Bracket A, which is designed to fit the majority of standard vehicle OBD2 ports. If Bracket A does not provide a secure fit, use Bracket G instead.

Step 2: Position the Bracket

Place the selected bracket directly over your OBD2 port. Use the included double-sided alignment tape to temporarily hold the bracket in place and help ensure the cover sits correctly before final tightening.

Step 3: Secure the Lock Cap & Fasteners

Fit the solid metal lock cap over the bracket. Secure it using 4 long screws in total, using 2 pieces of each screw type for improved tamper resistance.

Note: Your kit includes 8 long screws and 2 short backup screws. Always use the long screws first. The short screws are provided as alternative backup screws only.

Step 4: Apply the Concealing Stickers

For a clean and discreet finish, apply the included black blanking stickers over the screw heads. This step is optional, but recommended to help hide the fasteners from view.
