Honda Smart Key Indicator Flashing: Gold Wing Owner Guide

Quick answerOn the Gold Wing described in Honda's 2018 US owner's manual, the Honda Smart Key indicator should come on briefly when the ignition switch is turned on and then go out. Five flashes at switch-on mean the fob battery is low. Flashing that continues with the electrical system on means the bike has lost contact with the fob, either from radio interference or because the fob is no longer on the motorcycle, and Honda says this does not affect the bike until you switch off.

The three things the indicator does

Honda's US owner's manual for the 2018 Gold Wing describes one normal behavior and two warnings for the Smart Key indicator. Honda's other Smart Key models use the same indicator, with details that vary by model, so read the indicator page of your own manual.

What you see	What Honda says it means	What to do
Comes on briefly at ignition on, then goes out	Normal check	Nothing
Flashes 5 times at ignition on, with a low battery pop-up	The fob battery is low	Replace the CR2032 as soon as possible; Honda recommends having a dealer do it
Keeps flashing with the electrical system on	Communication with the fob stopped after switch-on: strong radio waves or noise, or the fob was lost while riding	Keep riding to a safe place, then check for the fob before switching off

Flashing while you ride

This is the warning that worries riders, and the manual's answer is calm: it does not affect the operation of the motorcycle until the ignition switch is turned off. The bike will not cut out because the fob stopped answering.

The manual does warn about the other end of the ride. If the fob was lost on the road, its battery is low, or strong radio noise is affecting the system, you may not be able to turn the electrical system off in the usual way. In that case Honda says to turn the ignition switch counterclockwise and hold it until the electrical system shuts off. After that, the bike will not switch on again without the fob or the emergency procedure, so choose where you stop.

Honda's checklist when the system does not respond

The troubleshooting chapter has a page titled for a Smart Key system that does not operate properly. It works through the fob first and the motorcycle last.

Is the fob switched on? Press its ON/OFF button lightly and watch the LED. The 2018 Gold Wing manual says to switch the system to activation if the LED does not blink 3 times, and to replace the fob battery if the LED does not respond at all. Other Honda Smart Key models show the fob's status differently, so use the LED description in your own manual.
Is something blocking the signal? The system uses low-intensity radio waves, and the manual lists strong transmitters nearby, a laptop or phone carried with the fob, and metal touching or covering the fob.
Is it a registered fob? The system cannot be activated without a Smart Key registered to that motorcycle.
Is the fob broken? A broken Smart Key cannot activate the system. Honda says to bring the emergency key and ID tag to your dealer.
Is the motorcycle's own battery healthy? Check the battery and its terminals. If the battery is weak, Honda says to contact your dealer.

The ID number backup

The Gold Wing's Smart Key comes with an ID tag carrying its ID number. The Gold Wing manual describes an emergency procedure in which the rider enters that number on the motorcycle using the start button and the fairing pocket opener, with a buzzer confirming each stage. When the number is authenticated, the steering unlocks and the electrical system activates, and you can start the engine. If it is not authenticated, nothing unlocks and you begin again. Leaving the buttons alone for about 20 seconds cancels the entry.

Two details matter in practice. The procedure has to be repeated each time you switch off, so it gets you home but does not replace a fob. And it only works if you have the number: Honda says to carry the emergency key and ID tag separately from the Smart Key, and to store a copy of the ID number somewhere other than the motorcycle. The exact steps are in the troubleshooting chapter under activating the electrical system in an emergency.

Fob problem or bike problem, and who can help

If the ID number brings the bike to life every time and the fob never does, even with a new battery and the fob switched on, the fob has failed or is no longer registered. If the fob's LED responds normally and the trouble only happens in one place, suspect interference at that spot. If nothing works, including the ID number, look at the motorcycle's battery before anything else.

For a lost fob, Honda's manual says a new Smart Key has to be registered, and it sends you to the dealer with the emergency key and ID tag. The mechanical side is separate: the built-in key and the emergency key are cut keys, and we cut those at the bike. For fob registration, call us with the model and year and we will tell you before the visit whether our equipment covers it or it has to go to the dealer. Have your photo ID and registration or title ready.

Quick questions

My Gold Wing's Smart Key light flashed five times when I switched on. What does that mean?

Honda's 2018 Gold Wing manual says five flashes at ignition on mean the Smart Key battery is low. It takes a CR2032, and Honda recommends replacing it as soon as possible.

Will the engine shut off if the Smart Key indicator starts flashing on the highway?

No. The manual says a flashing indicator with the electrical system on does not affect the operation of the motorcycle until the ignition switch is turned off.

I cannot switch my Gold Wing off and the Smart Key light is flashing. What now?

The manual covers this case: turn the ignition switch counterclockwise and hold it until the electrical system shuts off. Find the fob or have your ID number ready before you do, because you will need one of them to switch on again.

Where is the Smart Key ID number?

On the ID tag supplied with the motorcycle. Honda says to carry the tag separately from the Smart Key and to keep a copy of the number in a safe place away from the bike.
