From what I understand and read,the resistance values are kinda specific (that being the reason the security system works in the first place..) and also have a very small amount of variance allowed.
Being that my car has been sitting for 5 days or so,I looked at the key and said to myself..."Self?
Isn't that your resistor right there??"...So I rigged it this way.Besides,everything I did can be reversed except the wires being cut from the key cylinder (which would need to be replaced and were the cause of the problem in the first place).
Laters...

I had the same thing last week with the gauge fuse!! I was just about ready to replace the ignition mod that hooks to the ignition cyliner.
I had problems two nights ago with the starter barely moving. Found the connection on the battery had just a slight bit of corrosion scratched the h^& out of the connection and it started. So something easy to try!! This is on a brand new battery also.
MJK major kudos goes out for that one!!!!

MJK I just went through the same exact process you did! I was really mad at first because I didn't know what the hell was wrong with my car! I ended up putting a resistor that was the same as my key into the plug that runs to the BCM. Works like a charm! I think I will end up hiding a switch somewhere under my dash that interrupts the resistor, so that way I can turn it off and have less of a chance of someone stealing my car(since the resistor in the key is a "dummy" now). By the way, you can solder resistors end to end to achieve the resistance you need! Oh and most resistors have a 5% tolerance as well!
If I were to change out the lock cylinder, how would the bcm know what the resistance of the new key set should be? Would it need to be reprogrammed, or do you just take one of the keys that comes with the new ignition cylinder set to the dealer with your old key and have a copy of the new key made with the old resistance? What would happen if you lost your keys? Is the resistance of your key "on file" somewhere according to your VIN?

I think what the dealer does since the BCM is a ONE TIME program module,they have to order your ignition cylinder/key set according to the resistance of your current set.
I think they can get your resistance value off your VIN# or maybe by testing your original cylinder?Then they order the correct set out of 15 possiblities they have.That way it matches your current BCM.
I have heard that they have some sort of a device called the "interrogator" something or else and I bet that reads the BCM.If not,its probably an over glorified multimeter..Those are my theories...

Hi Folks
Just a little info for people that might need help. To get a Resistor value - use the following formulas:
(R1+R2..Ry)/X = R3 ex: (750+1000)/2 = 875 ohm these Resistors are parallel – “X” is the number of resistors in parallel
R1 +R2 = R3 ex: 750+1000= 1750 ohm - these resistors are in series
