go to GM dealer with VIN and proof of ownership and order new key.

The answer to that question is TOTALLY different depending on which engine your Gran Prix is equipped with. The choices are:

> V6-3.8L VIN 2
> V8-5.3L VIN C
> V6-3.8L SC VIN 4

This is really must know information - especially if you are asking somebody for help with your engine, engine accessories, or engine control systems.

Any time the check engine light is on the remote start is disabled. Doesn't matter what code is stored.

It all depends on what type of alarm you have installed on your Gran Prix. Make of alarm and fcc id number of the key fob would be helpful in determining how to put your alarm in valet mode, and still allow remote door unlocking, with alarm off.
