There are three way to defeat an immobiliser. The first is to find the unit and follow the wires back to where they immobilise the vehicle. This is where a small well hidden, hard to access immobiliser with cables dressed to look factory is really important (Don’t skimp on the installation).
The second is to simply disarm the system by cloning a remote or by having the over-ride number which is often easy to do!
This is why I love the Cobra Immobiliser. I found an old one from the now discontinued AB7928 and challenged a builder I know to see if he could open or destroy it with a hammer.
Here is what happened:
After admitting defeat he asked if he could attack it with a coal chisel and a lump hammer so here is what happened:
So the plastic surrounding case has finally been ripped apart to reveal a metal plate. It’s a good insight into how these are manufactured and the case is held together and filled with resin.
The insides are still intact and unlike all the other brands in NZ there are no spade terminals to simply plug together!
To put things into perspective here is an AVS immobiliser I attacked back in 2014:
And if you’re thinking the Cobra immobiliser is quite large then you’ll be pleased to know that the current 8509 immobiliser is half the size and made same way!
