Programming Instructions for 2016 Mazda CX-5 Smart Key Remote Fob

Important Notice: The 2016 Mazda CX-5 does not support on-board programming for smart key remote fobs. A certified automotive technician must perform the programming using advanced diagnostic equipment that interfaces with the vehicle’s security and immobilizer systems.

Programming Procedure:

• Step 1: Confirm that the replacement smart key fob is compatible with the 2016 Mazda CX-5 and has not been previously programmed to another vehicle.
• Step 2: Gather all existing remote fobs. In many cases, all current keys must be present during the programming session to remain active afterward.
• Step 3: Schedule service with a qualified automotive technician or authorized service center experienced in smart key programming.
• Step 4: If your vehicle is drivable, consider bringing it to the service location rather than requesting mobile assistance, as this may help reduce programming fees.
• Step 5: Prepare to present proof of vehicle ownership, such as a government-issued photo ID and the vehicle’s registration or title.
• Step 6: The technician will connect specialized diagnostic tools to your vehicle's onboard diagnostic port to begin the smart key registration process.
• Step 7: The system will then be accessed to register the new fob and, if necessary, reprogram any existing remotes.
• Step 8: Once programming is complete, the technician will test all key functions—such as lock/unlock, push-button start, and proximity entry—to ensure successful synchronization.
• Step 9: Request verification of how many remotes are currently registered to your vehicle to confirm that only authorized keys remain active.
• Step 10: Keep spare keys stored securely and test them periodically to ensure continued proper operation.
