Question about 1997 Cadillac DeVille
If it is anything like the expedition I own there is a chip in the key that needs to match the ignition for the vehicle to start.

you either have a bad key...did you try more than one key?
Two other things can be wrong..
1) the igintion cylnder (where ya put the key in) has samll wires that sense the pellet in the keys for your car, and often they break, and the cylnder has to be replaced.
2) the passkey module has gone bad.
Either of these problems can be fixed by any compatent mechanic that has cadillac experience.
