Where can I get a key and get it programed for Aurora Oldsmobile 2001?

Right, it may have something to do with it, but what if the remote isn't dead? Since the key and the remote are independent of one another, I don't think the two of them went bad, I think the anti-theft system on the vehicle needs to be scanned. You can try the key by having one cut, then programming it with a few steps: -turn key to on (engine off). security light will go off in 10 minutes -turn key to off and back to ON, ten more minutes, light goes off -repeat last step exactly, but after the third 10 minute wait an light shuts off, turn it off and remove the key. That's it.

IF the key is your problem > Security light in dash SHOULD be ON constantly.
