Subject: Re: vats chip? by NelsonV on 2011/6/6 17:32:37
The VATS is simply a resistor in the key which completes a circuit to the PCM. On me C5, I had the key, but my lock cylinder was going bad where the contacts inside mate to the key's resistor contacts. I simply measured the resistance in the key, then found a like resistor and jumped it into the pigtail that plugs into the lock cylinder.
I don't know how to determine a resistor value without the existing key. If you can somehow get that resistor value, you should be able to override the VATS. But then you still have to come up with a cut key...
