How to Replace a Smart Key

1. Replace your smart key by contacting your vehicle dealership. Smart keys are used by many auto makers and you must call your specific auto maker to obtain a new smart key.
2. Contact a local towing company to tow your vehicle to the car dealership. Since smart keys must be programmed to match your car's computer chips, you must tow your vehicle to the dealership.
3. Provide the car dealership your vehicle identification number (VIN), which is found on all of your purchase paperwork, insurance paperwork and title and registration. It is also found on your engine, in the driver door panel and inside the bottom-left side of your windshield.
4. Pay for your new smart key once the dealer has finished programming and creating your new smart key. The cost for replacement smart keys vary based on the make of your vehicle, but the average cost is around $200.
