Lost keys

lost the only copy key and remote to a 2000 aero 9-5 turbo wagon.  what r my options other than paying over $1,000 bucks for a twice unit?  any help would be appreciated!

did  you lock it with a key or with a remote?

thanks for replying roto; the car was down for maintenance, bad water pump, the doors are unlocked and no alarm was ever set.  received a call yesterday from a guy in oregon, he has an ad on ebay, says for $600 send him the twice unit and he'll reflash the unit and cut me two keys, no remote, but if i buy the remotes from ebay he would program them as long as they weren't locked.  what do u think?  anybody else have a say or suggestion?

Did you talk to a dealer? If the alarm was never set there's a chance that the dealer might help for less than 600.
