- Step 4: Within 5 seconds of getting to KOEO position, press the LOCK button on your remote control transmitter for one second.
- Step 5: Turn the key to the OFF position.
- Step 6: Go through steps 4 & 5 two more times. Totaling THREE ON/OFF cycles. Keep in mind that each step must be done within 5 seconds of the previous step.
- Step 7: Go back to KOEO mode. Now, press the LOCK button on your remote. The locks on your Honda will activate exactly as they do when locking. Your doors have not locked. This clicking noise indicates your Honda is now in Remote Programming Mode. Do not turn the key off.
- Step 8: When you program more than one remote, press the LOCK button on each additional remote for 1 second. Keep in mind you have 5 seconds to complete this step (as above). Programming Mode is enabled for only 10 seconds. Keep in mind that the door lock clicking is your signal that the fob has been successfully programmed.
- Step 9: Switch the system off, exit the vehicle, and retest to ensure successful reprogramming.
