Although you don’t need the original key, a professional will require certain information and documents to proceed:
Vehicle Identification Number (VIN)
Located on the dashboard or the driver’s side door frame.
Proof of Ownership
Registration, title, or insurance with your name.
Your ID
A valid driver’s license or government-issued ID.
Once verified, the locksmith will use the VIN to pull key codes from a database or directly decode the lock.

- Identification & Authorization
They’ll check your ID and proof of ownership to make sure you are the rightful owner of the car. - Key Code Retrieval
Using the VIN, they retrieve the key’s unique cut code or transponder code. - Key Cutting
They’ll use a laser or mechanical cutter to cut a new key blade. - Transponder Programming (if applicable)
If your car uses a chip key or key fob, it must be paired with your vehicle’s onboard computer. - Testing
The key is verified to ensure it starts the engine and operates the locks properly.
