<h1>2021 Honda Civic Keyless Entry Remote Fob (Smart Key)</h1> <p><font size="3"><b> Important Notice:</b> The 2021 model does not support onboard programming for smart key remote fobs. Programming must be completed by a certified technician using advanced diagnostic tools. </font></p> <p><font size="3"><b>Programming Procedure:</b></font></p> <ul> <li><font size="3"> Step 1: Schedule with a Certified Technician Contact a qualified automotive professional or authorized dealer who is equipped to handle keyless entry systems. The technician must have access to the necessary diagnostic tools. </font></li> <li><font size="3">Step 2: Evaluate Service Options If the vehicle is operational, driving it to the technician’s facility may reduce service costs and speed up the process, as mobile services typically incur additional fees. </font></li> <li><font size="3">Step 3: Prepare the Vehicle for Programming Ensure your vehicle is parked in an accessible and safe location. Confirm that the battery is fully charged and that all electronic systems are functioning properly. </font></li> <li><font size="3">Step 4: Bring Necessary Documentation In situations where no working fobs are available, proof of ownership—such as your registration or title—will likely be required before programming can begin.</font></li> <li><font size="3"> Step 5: Technician Connects Diagnostic Equipment The technician will connect a specialized diagnostic tool to the vehicle's onboard system. This step is necessary to access the programming mode and register the new remote. </font></li> <li><font size="3">Step 6: Program the New Smart Key Using the diagnostic interface, the technician will program the smart key fob into your vehicle’s system. This process ensures that the remote communicates correctly with the vehicle's security and ignition systems. </font></li> <li><font size="3">Step 7: Test the Remote for Proper Function After programming, the technician will test the remote to verify that all features—such as lock, unlock, and engine start—work as intended. </font></li> <li><font size="3">Step 8: Program Additional Fobs if Applicable If you have more than one remote, all fobs may need to be programmed during the same session. Have them available at the time of service to avoid synchronization issues. </font></li> <li><font size="3">Step 9: Final System Validation Once programming is complete, the technician will perform a full system check to confirm that everything is functioning correctly and that all programmed fobs are operational. </font></li> </ul> <p><font size="3"><b>Additional Considerations:</b> </font></p> <ul> <li><font size="3">Multiple Remotes May Require Simultaneous Programming: Some vehicle systems will deactivate other remotes unless they are programmed together. </font></li> <li><font size="3">Ownership Verification May Be Required: Especially in cases where no working fobs are present, ownership documentation is typically necessary. </font></li> <li><font size="3">Technician Experience Is Important: Always use a professional familiar with your vehicle’s electronic key system to ensure accurate and secure programming. For complete details, refer to your owner’s manual or consult a certified service provider.</font></li> </ul>
