The keys for my fiero are simply worn out after nearly 40 years of service.
Here is how to get new keys made when your keys are simply too worn to use a simple key cutter machine to duplicate.
1. Find your title 2. Order new key blanks from The Fiero Store. 3. Take your title to any GM dealer. 4. Go to the service desk and ask for the key codes (two are required for both ignition and trunk) for the Fiero. Your title is necessary to prove ownership. 5. Get a locksmith to cut your new keys from the key codes and your key blanks. 6. You now have newly cut keys for your Fiero!
