* Dealership: This is the most expensive option, but also the most reliable. They have the proper equipment and access to the vehicle's information to program a new key quickly and correctly.
* Locksmith: A reputable locksmith specializing in automotive keys will likely have the equipment to program a new Passlock key for your Cavalier. This is generally cheaper than the dealership. Make sure to choose a locksmith with good reviews and experience with GM vehicles.
* DIY (Not Recommended): There are some DIY methods discussed online involving bypassing the Passlock system. This is strongly discouraged. Bypassing the system is often unreliable, can damage your vehicle's computer, and may void any existing warranty. It's also potentially unsafe.
Before you go to a locksmith or dealership, you'll need to:
* Determine if you have the original key: If you still have an original key, it will make the programming process much easier and cheaper.
* Have your VIN ready: Your Vehicle Identification Number will be necessary for the programming process. It's usually found on the driver's side dashboard, near the windshield.
In short, there's no reset button. You need a new key programmed. Contacting a locksmith or dealership is your best course of action.
