Default Vats key

HI, Just measured resistence on 2 ignition keys for a 96 CE. One was in the 3 range - the other in the 7 range. I must be making a mistake. This isn't possible, is it? Regards, Don

Don, I think it is possible. If memory serves correct there are a few different ones. Someone here posted them quite awhile ago. What's important is you measure the resistance of your original and then match it.

Do both of them work? Are you sure you were making correct contact with the leads on either side? Did you clean them first?

Not too long ago, a member posted the full list of resistance values and the corresponding VATS code. I'm not sure; maybe 3-7 ohms are in one range; it's entirely possible, since you can get resistors up to 10 k-ohms commonly.

Thanks guys, I think I'll clean the contacts with alcohol - try again - and take the other key out and try it. (sometimes I miss the big picture). Regards, Don

I think there are 12 different VAT key resistance values if memory serves me correct. And I can tell you for sure that there are none down in the 5 ohm range. A value of 3000 or 5000 might be in the ranges used for the keys. From memory again, I think I have key 6 and mine measures 1462 ohms (1.462K).

The mystery seems to be solved. The other key in question wouldn't turn on the ignition. But the THIRD vats key in my hide a key did. Therefore, when I bought my car three years ago, he must have included his wife's car keys. (not a bad idea). THANKS! Don
