I went to the dealer today, and they said they could make me a key even though its older than 10 years. But he said he advises me to get the key along with a new ignition cylinder, just in case the cylinder has ever been changed, in which case the original key wouldnt work and I would've wasted 50 bucks. So he said it'd cost about 110 for a new ignition cylinder and key. So I'm in the process of ripping apart the steering column and changing the cylinder. He said he'd be able to make the door key as well, so I think you would be better off trying the dealership. Good luck!

 

They made my key for $40
