1. Key Blank: The key blank itself can range from approximately $50 to over $100. This cost may vary based on the vehicle model and the type of key needed.
2. Programming: Transponder keys require programming to match the vehicle's immobilizer system. Programming costs can vary widely, but typically fall between $50 and $200. Some dealerships or locksmiths may charge a higher fee for programming.
3. Cutting: The key may need to be cut to match the vehicle's ignition lock cylinder. Cutting fees usually range from $10 to $50.
4. Dealership vs. Locksmith: Getting a replacement key from a dealership may cost more than going to a locksmith. Dealerships often charge higher prices for keys and programming, while locksmiths may offer more competitive rates.
5. Online Retailers: Some online retailers sell replacement keys for vehicles, but it's important to ensure the key is compatible with your specific model. Prices online can vary and may be more affordable compared to dealerships or locksmiths.
