How to change or re-key the Driver's side door on a 1998 Saturn?

You can have the Lock Re-Keyed. You must call a lock Smith who will do it. They take the lock from your glove box and match it with the door since they are the same. Then they cut a new one on the spot. Or they may take the VIN Number and they can cut a key off of the numbers. Call your local Locksmith and find out More!
