Help with Key Vats number
Okay I need to get a new key. I checked the resistance on my VATS chip and it came out 11.89. So my question is do I have a number 11 or 12?
Thanks,
Kevin

I'd say #15 from my info. Here you go:
VATS key codes:
The BCM measures the resistance value of the resistance of the pellet and allows the fuel system to operate. If it is within +/-10% the car will start.
To check your key value:
Set your digital volt meter to “ohms mode” and measure the value across the pellet.
The 15 resistor codes are:
Resistance Value (Ohms)
1 0.402 (acceptable range .386-.438)
2 0.523 (acceptable range .502-.564)
3 0.681 (acceptable range .650-.728)
4 0.887 (acceptable range .850-.942)
5 1.130 (acceptable range 1.085-1.195)
6 1.470 (acceptable range 1.411-1.549)
7 1.870 (acceptable range 1.795-1.965)
8 2.370 (acceptable range 2.275-2.485)
9 3.010 (acceptable range 2.890-3.150)
10 3.740 (acceptable range 3.590-3.910)
11 4.750 (acceptable range 4.560-4.960)
12 6.040 (acceptable range 5.798-6.302)
13 7.500 (acceptable range 7.200-7.820)
14 9.530 (acceptable range 9.149-9.931)
15 11.801 (acceptable range 11.320-12.290)
