Harley-Davidson Security System: Fob, PIN and Lost Keys

Quick answerThe 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. Every bike with the system also has a five-digit PIN the owner can enter if the fob is lost or dead, so a missing fob does not have to strand you. The fob and the key are separate things: the fob handles security, and the barrel or flat key still works the ignition switch lock, fork lock and luggage.

Harley-Davidson Smart Security System quick facts

Only two fobs can be assigned to the security module at one time, and Harley says a trained Harley-Davidson technician has to assign a replacement.
The PIN is a five-digit number that uses the digits 1 to 9, with no zeros.
The system arms itself within about five seconds of the ignition being turned off, and the fob range is about five feet.
If you ride away without the fob, the odometer window briefly shows NO FOB.
The fob takes a CR2032 coin cell, and Harley's owner's manuals say to replace it every year.
The older Harley-Davidson Factory Security System used a fob with a button and a personal code in place of the hands-free fob and PIN.
Harley's 2011 Softail and 2014 Dyna owner's manuals describe the security system as optional equipment.

Which bikes have Harley-Davidson Smart Security System?

Years	Models	Notes
2007 and later	Touring, Softail, Dyna, Sportster and V-Rod models with the hands-free Smart Security System	Fitted at the factory on some models and sold as a Harley accessory kit for others. Harley's accessory listings show kits for 2007-and-later V-Rod, Dyna and Softail models and for 2014-and-later Sportster and Touring models, so check your own bike before assuming it has one.
2018 and later	Softail models with keyless ignition	There is no keyed ignition switch. The bike starts with the fob nearby or the PIN, and a barrel key works the fork lock.
2021 and later	Revolution Max models: Pan America, Sportster S, Nightster	Keyless ignition with the fob, with the PIN as the backup.
mid-2000s and earlier	Bikes with the H-D Factory Security System	An earlier system with a push-button fob. The owner arms and disarms it with the fob button or a personal code entered with the turn signal switches.

How the system works for the owner

Harley's owner's manuals describe three parts: a control module and an antenna on the motorcycle, and a hands-free fob that the rider carries. You do not press anything. When you park and turn the ignition off, the system arms on its own within about five seconds, flashes the turn signals twice, and from then on the starter and ignition are disabled. If someone tampers with the ignition or tries to move the bike, the module sets off the alarm: flashing turn signals, plus a siren if the optional siren is fitted.

When you come back with the fob, the system disarms as you switch on or move the bike. The manuals give the fob's range as about five feet. Harley tells riders to carry the fob in a pocket, not on the handlebars or in a saddlebag or Tour-Pak. A fob left with a parked bike keeps the alarm from working, and a fob stored in a metal case or right next to a phone may not be detected.

What comes with the bike: fobs, the PIN and the key

A security-equipped Harley has more than one thing to keep track of, and each one does a different job.

Item	What it does	If it is lost
Hands-free fob	Disarms the security system when it is near the bike	Use the PIN to ride; a Harley-Davidson dealer assigns a replacement
PIN	Five digits, 1 to 9, entered with the turn signal switches to disarm the system without a fob	With a working fob present the rider can set a new PIN; without either, the bike needs a dealer
Barrel or flat key	Locks the ignition switch, the fork lock, and saddlebags, Tour-Pak or fuel door where fitted	A locksmith can cut a new key, or a dealer can order one by key code
Wallet card and manual page	A place to record the PIN and the key number	Record both again as soon as you have them

What the owner's manual says about a lost or dead fob

The manual is direct about this: if the fob is misplaced, its battery is discharged, or strong electromagnetic interference stops it communicating, the rider disarms the system with the PIN. The PIN is entered with the left and right turn signal switches while the odometer window shows the prompt, and the full table of steps is in the security section of the owner's manual for your model and year. Once the system is disarmed the bike starts normally. It will arm again when you switch off, so you repeat the PIN each time until you have a working fob.

Three details from the manual are worth knowing before you need them. If the bike is moved during a PIN entry, the alarm goes off. If an attempt fails, Harley says to wait two minutes before trying again. And the system only arms in the first place once a dealer has assigned the fob and a PIN has been entered, which is why the dealer sets a PIN at delivery. You can change it to a number you will remember, but the change procedure needs an assigned fob present, so do it while your fob still works.

Replacement fobs are sold by Harley-Davidson dealers. The module holds only two fobs at a time, each fob has its own serial number printed inside the case, and the manual states that only a trained Harley-Davidson technician can assign one to a motorcycle.

Dash messages and the security lamp

Security lamp flashing every few seconds with the bike parked: the system is armed. This is normal.
Security lamp on solid for about four seconds, then off: the system has just disarmed.
NO FOB in the odometer window: the bike was ridden away without the fob in range. It keeps running, but you will need the PIN to restart it after you switch off.
ENTER PIN in the odometer window: the system is armed and waiting for the PIN during a manual disarm.
FOB LOW BATT on fairing models: replace the CR2032 coin cell in the fob.
Security lamp staying on while you ride: Harley's manual says to see a dealer.

The fob is not the key: what the barrel key still does

A common mix-up is treating the fob as a replacement for the key. On most Harleys it is not. On Touring models with a fairing, the barrel key locks the ignition switch knob in the fork lock or accessory position. On the Road King and on 2017-and-earlier Softails, it locks a switch on the tank console, and a separate fork lock sits at the steering head. Harley recommends taking the key out before riding, so many owners rarely handle it, and that is usually how it goes missing.

The same key also works the hard saddlebag latches, the Tour-Pak latch and the locking fuel door on Touring models. Lose it with the bike locked and the security system is not your problem at all: the fob and PIN will disarm the alarm, but they will not unlock a fork lock or a saddlebag. That is a key and lock job, and it is the part a mobile locksmith handles at the bike.

Dealer or mobile locksmith?

Split the job by what is missing. For a lost or failed fob, go to a Harley-Davidson dealer, and use the PIN to ride there. For a lost barrel or flat key, a locked fork, a worn ignition switch or a saddlebag lock that will not open, we come to the bike and handle it on site. If you have lost the fob and do not know the PIN, the bike cannot be started under its own power, so call the dealer first and ask what they need from you.

Have this ready when you call us: the model and year, the VIN, your photo ID and the registration or title in your name, whether the bike has the security system, and which locks are affected. If any original key survives, look under its plastic head cover for the stamped key code.

Harley-Davidson Smart Security System FAQ

Can I ride my Harley without the fob?

Yes, if you know the PIN. The owner's manual explains how to disarm the system by entering the five-digit PIN with the turn signal switches, and the bike then starts normally. You will need to enter it again each time you switch off.

What does NO FOB mean on my Harley?

It means the bike was ridden off and the security module can no longer detect the fob. The engine keeps running, but after you switch off you will need the fob or the PIN to start again.

I lost my fob and I do not know the PIN. What now?

That is a dealer job. Harley assigns fobs through its dealers, so contact a Harley-Davidson dealer with your VIN and proof of ownership and ask how they want the bike brought in. We can still help with any locked fork lock, ignition switch lock or luggage lock.

How often should I change the Harley fob battery?

Harley's owner's manuals say to replace the fob battery every year. It is a CR2032 coin cell, and the manual shows how the fob case opens.

Does a new key need to be programmed to the security system?

No. Harley barrel and flat keys are mechanical and have no chip, so a newly cut key works as soon as it fits the lock. Only the hands-free fob is assigned electronically.

Does every Harley have the security system?

No. It has been standard on some models and optional on others depending on the year and market, and Harley's own manuals as recent as the 2014 Dyna call it optional. A security lamp that flashes after you park and a fob in the original delivery kit are the usual signs that your bike has it.
