Key locked OBD2 Port Cover

 
Presenting our CarGuard lockable OBD2 port cover. It is a purpose-built solution designed to secure your vehicle’s diagnostic port, one of the most commonly exploited access points in modern car theft. Unlike basic covers that rely on tamper-resistant bolts or generic fasteners, your OBD2 port is protected by a true keyed locking mechanism, giving you genuine control over access.
 
Manufactured from high-strength cast aluminium, this is not a plastic add-on or a temporary deterrent. It is a solid, engineered component built to withstand tampering while maintaining a clean, factory-style fit.
 
Why Your OBD2 Port Matters
Modern vehicle theft has evolved. Many targeted vehicles across Australia, including popular models like Toyota LandCruisers and Holden VE and VF Commodores, are being accessed through the OBD2 port to bypass factory immobilisers. This method allows thieves to reprogram keys and drive away in minutes.
 
That is exactly why securing this access point has become a priority, with Victoria Police actively recommending OBD port protection as part of a broader anti-theft strategy.
