Harley-Davidson Softail and Fat Boy Key Replacement

Quick answerSoftail models through 2017 use a round barrel key that locks the ignition switch, usually on the tank console, plus a separate fork lock on the right side of the steering head that takes the same key. Softails from 2018 on are keyless: the bike starts with the security fob nearby or your PIN, and a barrel key remains for the fork lock. In both generations a lost key is a mechanical job done at the bike, while a lost fob is a dealer job.

The key and switch by generation

For most of the Softail's life the layout has been the same. The ignition switch sits in the instrument panel on top of the tank. Harley's 2011 owner's manual describes it this way: lift the switch cover, insert the key and turn it clockwise to unlock, then rotate the switch itself to ACC or IGNITION. The switch can be locked in OFF or ACC. Because the key is not needed once the switch is unlocked, the manual tells you to remove it before riding so it cannot fall out.

Two groups break the pattern. The Rocker of 2008 to 2010 and the Blackline and Breakout that followed carry the switch on the left side of the bike between the engine cylinders, with a thumb lever that the key locks and unlocks. And from the 2018 redesign on, Softails have no keyed ignition switch at all. The security system detects the fob, and the bike is switched on from the handlebar.

Fork lock and luggage

Harley's Softail owner's manuals from the 2005 to 2011 model years describe the fork lock the same way: it is incorporated in the steering head on the right side, and it is locked with the fork turned full left by inserting the key, pushing in and turning. It takes the ignition key. On 2018-and-later bikes this is the lock the barrel key is for.

Luggage varies more. Traditional Heritage Softail Classic saddlebags close with straps and buckles, and many have no lock unless one was added. Harley sells keyed locks for soft-sided leather and vinyl bags and lists dedicated saddlebag locks for 2011-and-later CVO Softails, all of which can be ordered to the bike's key code. If your bags have locks, check whether they share the ignition key before you are down to one copy.

Security fob by year

The fob story on Softails has three stages. Bikes from the mid-2000s could have the H-D Factory Security System, with a fob you press to arm and disarm. From 2007 Harley offered the hands-free Smart Security System, and its 2011 Softail manual still calls the system optional, so plenty of 2007 to 2017 Softails have no fob at all. On the keyless 2018-and-later bikes the fob is part of how the bike starts.

On any fob-equipped Softail, the five-digit PIN is the backup. If you ride off without the fob, the odometer window shows NO FOB, and the bike will need the fob or the PIN to restart.

What a lost-key visit involves

Tell us the year and model first, because that decides the job. For a 2017-and-earlier bike we come out, check your photo ID against the registration or title, and make a barrel key that works the ignition switch lock and the fork lock. For a 2018-and-later bike with a lost barrel key, the work is the fork lock key. If the fob is what is missing, use your PIN and book a Harley-Davidson dealer to assign a new one.

A worn console switch is a separate problem from a lost key. If the key turns but the switch is loose, intermittent or will not stay locked, the switch can be repaired or replaced.

Where to find the key code

The key code is stamped on the metal of the key head, under the black plastic cover if the key has one. The owner's manual has a space at the front for the key number. Barrel codes are four digits on older keys and four digits plus HD on 2012-and-later keys, and a Harley-Davidson dealer can look the code up by VIN.

Harley-Davidson Softail and Fat Boy key FAQ

Where is the fork lock on a Fat Boy?

On the right side of the steering head. Harley's Softail manuals describe it as incorporated in the steering head, separate from the ignition switch, and it takes the ignition key.

Does a 2018 or newer Softail have a key?

Yes, but not for starting. The bike starts with the fob nearby or the PIN, and the barrel key is for the fork lock.

My Softail has no fob. Is something missing?

Not necessarily. On 2017-and-earlier Softails the security system was optional in at least some years, and many bikes were sold with keys only. A security lamp that flashes after you park is the sign that the system is fitted.

Can I leave the key in the console switch while riding?

Harley recommends against it. The manual says to remove the key before operating the motorcycle because it can fall out, which is a common way these keys are lost.

The immobilizer system on this bike

Harley-Davidson Security System: Fob, PIN and Lost KeysThe Harley-Davidson Smart Security System is a factory alarm and immobilizer that disarms when it detects a hands-free fob near the bike and disables the starter and ignition when it does not.
