How much is it to get one made at the dealership for a 1993 SE?

Forget the dealership, it'll be 3x more than at a locksmith. Call a couple locksmiths and ask if they can copy the VATS or Passkey systems. There are only 12 different key blanks, and most decent locksmiths have the interrogator, or know how to use a multimeter.

cool. i might be able to get one cheap though. I just remembered, I know a few people at the local Chevy/GMC/Hummer dealership that makes all GM brand keys

I had 2 spare ignition keys and 2 spare door keys copied at a local locksmith for $30.

Unless you're absolutely anal-retentive like me and MUST have GM keys.

or just find the resistance of the key and install a inline resistor on the wires, no more VATS issues

or just install remote start

edit: duh, still need key unless..
you hook up relay to leave bypass on all the time
