    • To get a replacement key for your 2011 Mazda CX-7, you’ll need the key code, which is tied to your VIN (JM6ER10L2B0222743). Visit your local Mazda dealership with proof of ownership (e.g., title, registration, or insurance) and a photo ID. They can retrieve the key code and cut a new key for you. Alternatively, contact a professional automotive locksmith who can cut and program a key using the VIN or by decoding the lock directly. If your key has a transponder, programming will be necessary, which both the dealership and locksmith can handle. Avoid posting your VIN publicly for security reasons and provide it only to trusted professionals.
