Programming Instructions for 2020 Mazda CX-5 Smart Key Remote Fob

Important Notice: The 2020 Mazda CX-5 does not support on-board programming for smart key remote fobs. Programming must be performed by a trained automotive technician using specialized diagnostic tools capable of interfacing with the vehicle’s electronic control systems.

Programming Procedure:

• Step 1: Verify that the new smart key fob is compatible with the 2020 Mazda CX-5 and has not been previously programmed to another vehicle.
• Step 2: Gather all existing smart keys. Some Mazda systems require all remotes to be present during the programming process to ensure continued functionality.
• Step 3: Schedule service with a certified automotive technician or authorized service center equipped for smart key programming.
• Step 4: If the vehicle is operational, consider driving it to the service location to minimize additional fees that may apply for mobile service.
• Step 5: Be prepared to present proof of ownership—such as vehicle registration and a government-issued photo ID—before programming can proceed.
• Step 6: The technician will connect a diagnostic interface to your vehicle’s onboard diagnostic port to access the smart key programming function.
• Step 7: The technician will register the new smart key and, if required, reprogram any existing remotes to ensure all keys remain active.
• Step 8: After programming, the technician will test all functions of the smart key, including lock/unlock, proximity entry, and push-button ignition.
• Step 9: Confirm with the technician how many keys are now registered to the vehicle, and ensure that only authorized remotes remain active in the system.
• Step 10: Store any additional remotes securely and periodically test them to verify continued operation.
