The process generally involves:
* GM Tech 2 Scanner (or equivalent): This is a professional-grade scan tool that communicates with the car's computer system. It's essential for properly programming the fob's unique ID to the vehicle's security system. Trying to use cheaper, less sophisticated tools will almost certainly fail.
* Specific Programming Procedures: The exact steps vary depending on the year, make, and model of your Chevy. The process involves connecting the scanner to the car's OBD-II port and following the manufacturer's instructions to add the new key fob to the vehicle's memory.
Why you can't usually do it yourself:
* Security: The programming process is designed to be secure to prevent unauthorized key duplication.
* Complexity: The car's computer system requires specialized software and knowledge to interact with properly.
* Risk of damage: Incorrect programming could potentially lock you out of your vehicle or damage the car's computer system.
What you should do:
1. Go to a Chevrolet dealership: This is the most reliable and recommended option. They have the correct tools and expertise.
2. Contact a qualified locksmith: Some locksmiths specialize in automotive keys and fobs and may be able to program your key fob for you at a potentially lower cost than the dealership. Make sure they have experience with Chevy vehicles and the necessary equipment.
In short: Don't attempt to program a Chevy key fob yourself unless you have extensive experience with automotive electronics and the correct professional-grade tools. The risk of failure and potential damage outweighs any cost savings from DIY.
