Motorcycle Key Fob and Keyless Ignition Problems

Quick answerMost keyless motorcycle problems come down to a weak fob battery, a fob the bike is not reading, a damaged fob or a lost one. Start with a fresh coin cell, then use the backup your maker provides, which is a PIN, an emergency key or a code depending on the make. The one thing that cannot be fixed at the roadside is a backup you never set up, so find your PIN, code card or emergency key now.

Which motorcycles use a fob?

Fobs are less common than chip keys, and they belong to specific models. Harley-Davidson's hands-free fob comes with the H-D Smart Security System, which is standard or optional depending on the model, year and market; the 2018 and later Softails and the Revolution Max models are keyless, while Touring models still have a switch knob locked with the barrel key. Indian uses a fob on the Chief, Chieftain, Roadmaster, Challenger and Pursuit, but the Scout through 2024 and the FTR have an ordinary cut key.

Elsewhere it is model by model: BMW Keyless Ride, Ducati Hands Free on the Multistrada, Diavel and XDiavel families, KTM RACE-ON on the big twins, Triumph's keyless models, Kawasaki KIPASS on the Concours 14, Honda Smart Key on the 2018 and later Gold Wing, and Yamaha's smart key on the Star Venture, XMAX and TMAX.

Know your backup before you need it

Every keyless system has a documented way to carry on without the fob, and the owner's manual explains how to use it. Harley-Davidson's is a five-digit PIN; the dealer sets the first one, you can change it, and the manual has a wallet card for recording it. Indian's dealer supplies a master PIN with the bike, and the manual tells you to change it to your own rider PIN. If both are lost, Indian says only a dealer can retrieve the master PIN.

Other makes use an object instead of a number. BMW supplies an emergency key with every Keyless Ride bike, Kawasaki's KIPASS fob holds a mechanical emergency key, Ducati supplies a passive key and lets the owner store a PIN, Honda supplies an emergency key and an ID tag, and Yamaha supplies a smart key emergency code card. Yamaha says it keeps no record of that code.

Read that section of your manual at home, and keep the PIN, card or emergency key somewhere you can reach without the bike and without the fob.

If the fob is lost

A lost fob is two problems: getting moving today, and getting a second fob so you are not relying on a backup. Your PIN or emergency key covers the first. For the second, Harley-Davidson has its technicians assign fobs and its security module holds two at a time, and Indian says only its dealers can sync a fob. Fobs for other makes depend on the model and year, so ask with your exact bike.

If the fob may have been stolen along with something showing where the bike lives, ask for it to be removed from the bike's memory when the new one is paired. The mechanical key for the fork lock, seat or luggage is separate from the fob and can be cut on its own.

We program fobs and transponder keys for the makes and years our equipment covers, at the bike, and we ask for photo ID and the registration or title first. We will tell you before the visit if your model has to go to the dealer.

Habits that prevent most fob trouble

Change the coin cell on a fixed date each year; Harley-Davidson and Indian both recommend yearly
Carry the fob in a pocket away from your phone and other keys
Keep the spare fob at home, not on the bike or in the luggage
Record your PIN or code in two places that are not the motorcycle
Get a second fob while the first still works

Quick questions

Can a locksmith program a motorcycle smart fob?

It depends on the make and year. Harley-Davidson and Indian fobs are handled through their dealers, while some other systems can be programmed with locksmith equipment. Ask with your exact year and model before booking.

Should I keep my spare fob on the bike?

No. A fob stored on or in the bike defeats the security system, and two fobs near the bike can make the system read the wrong one. Keep the spare at home.

My fob stopped working right after a battery change. Is it unpaired?

Probably not. Check the battery type and orientation first, and make sure the case is fully closed. Indian, for one, says a battery change does not require re-syncing.

Do all Harley-Davidson and Indian motorcycles have a fob?

No. Harley's security system is standard or optional depending on model, year and market, and Indian's Scout through 2024 and FTR use a plain cut key. Check whether your bike came with a fob before assuming it needs one.
