any help please

hello there.
I know this is old, but where you able to sort this car?
i have a guy that has a 97 Trans AM, and i need to know if i could do IMMO Off to the Car or program new keys.
Supposedly someone changed the ECU and tried to do IMMO OFF, but car doesnt work now...

Can you help me with some info?
Thanks

That should have a resistance pellet on the key

You need a variable resistor to determine the right resistance for the Passkey in the new ECM. Connect it across the Passkey connector ECM side (connector disconnected) (orange wire harness on the column) and set it to the first resistance and see if the car cranks. Then wait about 5 minutes (for Vats to timeout lockout for wrong value) and test the next and so on. Once you find the correct resistance, cut a new key with that pellet, or put that value resistor on the ECM side of the disconnected connector.

thanks for the info...
do you have any link for a video or any tutorial that could let me understand a little bit more about this procedure?
i never worked on this type of system, so i don't know what i will find...
i will see the car in a few hours because they cant run the car...

Really appreciate your comments...
Thanks

so i found some videos on youtube and i think its not that hard...
Another question: if there is no key with the "chip" or resitor, how can we find the correct value?
do we need to test "one by one"?

Thanks
