How to Program a Keyless Remote for a Honda
- 1). Enter your Honda vehicle and open your driver's side door.
- 2). Insert your key into the ignition and turn the key from the "Acc" position to the "Lock" position three times within about three seconds.
- 3). Close and open the door twice in quick succession within 10 seconds of the last step and then cycle the ignition key from "Acc" to "Lock" three more times in the next three seconds.
- 4). Close and open the driver's door again and wait for the door locks to automatically cycle immediately after.
- 5). Press and hold the "Lock" button on any remote that you would like to use within 20 seconds of the last step. Each remote will indicate successful programming by operating the locks on the car automatically. Remove the key from the ignition once you have finished.
