Thieves are now bypassing car security systems via your car’s OBD port located in the driver’s foot well. This enables them to make a copy of your ignition key and take the car without setting off any alarms

Firstly unclip your original port and clip the dummy in its place. Then plug the red connector on the dummy into your genuine port. Close the locking clip to avoid loose connections and short circuits. Now relocate the original to a place of your choosing out of sight to a thief. Using the cable ties supplied strap the dummy lead to your cars wiring loom to make it look like the original port.

If connected to, the port will power up the criminal’s equipment but obviously will not be able to read data. He will think it's the original port and that it has been somehow blocked so he will not think about looking for the original which you have relocated behind the dash - at this stage they are unlikely to hang around to hunt for it.

"If a criminal was to break into your car with the dummy port fitted the alarm would go off. They will connect their kit. It would power up just like the real port but nothing else would happen. They would not be able to turn off the alarm or release the doors dead locks. They won't want to be climbing through the window into your car where they can't make a quick getaway to work out why their kit isn't working. Worst case scenario is you get a broken window but at least your car will not get stolen."
