Doesn't keep from using a heli to lift the car ... I admit ...

I bought a 2nd hand 2004' 1600 Civic, 4 doors for my wife ... and of course, less than a week later, she forgot the unique key inside !!!

Took me less than 5 Minutes to re-open it ... without damaging anything !!!

Understand, if I had been the thief with my Obd terminal ... the car had been started in seconds ...

The simplest anti theft will here be the best ... Engine not starting !!!

I took my Dodge pickup to Vegas a few weeks ago, went to all the casino's, parked in the free parking, etc.etc. Everywhere I went, after parking, I popped the hood (bonnett?) and took the main ignition coil wire with me. (Was that an ignition coil wire in my pocket or was I just happy to see them )
But as you say, would that stop a relatively knowledgable thief from taking a spark plug off a cylinder and putting it in the main wire's place (actually, it would in this case because the main coil wire is a lot longer than any plug wire)? Probably not...
And you guys have given me some good ideas on what to do with the CAN bus, sniffing the bus, logging parameters, etc. Now I just have to buy a car with CAN instead of ISO9141.
