Take off the lower panel on the driver side and you'll see two small wires that head up the steering column toward the ignition cylinder. Yellow and brown if I recall correctly, but I'm not positive. You'll need to wire resistors between these wires equal to the value of your VATS code. This method costs about $.50 from Radio Shack or buy the kit from Ecklers for $30 that does the same thing.

I was checking what ohm my key was with a ohm meter, nothing on the meter? I have a 96 OBDII. How can you check a good key ? As my system is OK,

There are 15 key codes each relating to a specific resistance. Key code #1 is the lowest resistance which is 402 ohms. 8 ohms is not a realistic value and was probably measured wrong. The range of resistance goes up to 11,800 ohms. If you know what key code you have, you then can come up with the appropriate resistance using the chart.

if the car and vats are working properly. A good locksmith can probably fix you up for about $15.

Hi Jimi/Louis....Are you guys bridging across both resisters??(bumps on the key) Are the bats dead in your multimeter?? Should be a piece of cake.

I have a Fluke Clamp Meter model 333 will Not adjust. Checks ac.dc.ohmm and amps ( clamp end CAT III 600V 400 amp) ) used the + and - on the key like you posted " Nothing " 0.0 on screen. Touched + and - and a buzzer sounds. Meter works. Corvette works but not able to turn On alarm. I have new fob and have tried several times with several pages of step by step instructions on doing this. It gets much more detailed than what is in the Red GM books that are for a 96 Corvette only. Purchased a VCR with instructions and a CD that had instructions on doing this.......sigh.

Possible your clamp meter is limited to wire/cable readings only. Take your key to a Radio shack & have the dude do a point to point contact reading on those 2 resisters. Publish your resistances & former VATS nbr. I'll ck for applicable VATS nbr & publish my findings directed to you.
Should work.
Should work.

Thanks, will do that and borrow a different meter. See if both readings are the same.
