Newer VATS Vehicles

     Why not just carry a spare computer, unplug the original, plug the 
     other in and off you go.

Technical knowledge is great but it doesn't necessarily give you time to 
defeat it. The guys here that have cracked it have done it one of two ways. 
Either by trying each of 15 resistor values until it unlocked (with a 3-4 
minute delay between each try) or by hacking the PROM which requires 
removing the computer, pulling the CalPak, removing the PROM, downloading 
it, editing it, blowing a new PROM and putting it all back together again. 
A thief just doesn't have the time to do all of this. He might be able to 
carry a spare CalPak with a modified PROM already in it but even if the 
thief decides to concentrate on a Corvettes there are about 8 different 
CalPaks he would have to carry. It still easier to use a tow truck or steal 
the keys.
