For the key, read your owners manual to see if it mentions a "Pass Key" system. If it has Pass Key, it is chipped.
Otherwise, go to HomeD and have them copy the key for a couple bucks and try it. My 99 does not have a chip in it.
If it has a chip in the key, you can also find brand new blanks on ebay. I bought 2 of them. Take them to your local key cutter and have them cut to match your original. Then follow the easy programming

If it has a cross in the circle (like pictured above) in the shank under the plastic head.
You have a "transponder" key.

All GMT800's have NO chip in the key, you can see it on the key. GMT800 trucks have the chip in the tumbler and a reader in the housing. Any key correctly cut will start the vehicle as long as the column, PCM & BCM relay the correct values.
See this post.
