Programming Instructions for the 2021 Acura ILX Keyless Entry Remote Fob (Smart Key)

Important: The 2021 model does not support onboard programming for smart key remote fobs. Programming requires professional diagnostic tools and must be performed by a qualified technician.

Step-by-Step Programming Instructions:

• Step 1: Verify that the smart key fob is compatible with your vehicle and has not been programmed to any other vehicle.
• Step 2: Contact a certified automotive technician or service center that specializes in keyless entry and smart key programming.
• Step 3: Confirm that the technician has access to manufacturer-level diagnostic equipment required for secure key programming.
• Step 4: If your vehicle is operable, consider driving it to the service location rather than requesting mobile service, which may help reduce overall costs.
• Step 5: Bring all currently programmed smart keys with you. Some systems require all keys to be present during the programming process to avoid deactivation.
• Step 6: Upon arrival, the technician will connect a diagnostic device to your vehicle’s onboard port, usually located under the dashboard.
• Step 7: Using specialized software, the technician will initiate the programming procedure and register the new smart key with the vehicle’s security system.
• Step 8: Once the process is complete, the technician will test all features of the newly programmed smart key, including locking, unlocking, and engine start.
• Step 9: If you have additional keys to program, they can typically be added during the same session.
• Step 10: Before leaving, confirm that all smart keys function properly and that the vehicle responds to each remote as expected. "
