Immobilizer key?

[1weasel]

I was thinking. In my '97 is there a chip in the key?

there should not be a chip in your key. we make tons of chevy keys at work, and so far i have not seen one in anything other than the newer body styles.

Sounds good.

Immobilizers in full size GM trucks weren't incorporated until the 99 pickups and 2000 nbs SUVs came out.
