Buell XB Firebolt, Lightning and Ulysses Key Replacement

Quick answerA Buell XB uses one plain key with no chip for everything: the ignition switch on the upper triple clamp, the steering head lock built into that switch, the locking fuel cap on top of the fuel-in-frame chassis and the seat lock. Lose it and you cannot start the bike, refuel it or open the keyed seat, but one correctly cut key restores all of that, and it can be made at the bike.

Where the locks are on an XB

The XB chassis moved things around, and the locks went with them. Fuel is carried inside the frame spars, so the filler cap is on top of the frame ahead of the seat, where a tank would normally be. The ignition switch is on the upper triple clamp in front of the rider.

Ignition and headlamp switch: turn clockwise to ON to ride. The tail lamp is lit in ON and in the park position.
Steering head lock: sidestand down, bars full left, key in OFF, then push the key in and turn it counterclockwise to LOCK, moving the bars slightly until it engages.
Fuel cap: lift the tab, quarter turn counterclockwise with the key, lift the cap off. Refit, quarter turn clockwise, remove the key and push the tab down.
Seat lock, Ulysses: quarter turn clockwise, then pull the seat toward the rear of the bike.
Helmet lock, Ulysses: with the seat lock turned, the helmet D-ring goes into an open clasp and a quarter turn back closes it.

Why one lost key stops everything

On many bikes a lost key still leaves you some access. On an XB it does not, because the fuel cap and the seat are both on the ignition key. A Firebolt or Lightning with no key cannot be refueled, and on a Ulysses the seat and anything secured with the helmet clasp stay put.

The upside is the same fact turned around. Since every lock on the bike is cut to one key, there are several locks to work from when a new key has to be made, and a single new key puts the whole bike back in service.

XB trouble spots

The fuel cap lock sits face-up on top of the frame, in the weather and in the path of spilled fuel and wash water. If the key is starting to bind there, have the lock cleaned and the key checked for wear before it twists.

The Ulysses manual has owners press the key into the Triple Tail locking detent to release the rack. That is one more job for the same key, so look at the tip now and then, and keep a spare.

The switch also has a parking-lamp position where the key comes out with lights still on, and the manual warns that lamps left on will eventually discharge the battery. A flat battery after parking is more often this than a fault.

All keys lost on a Firebolt, Lightning or Ulysses

We come to the bike and confirm ownership with your photo ID and the registration or title. A new key is cut to the bike's locks and tested in each one: ignition ON and OFF, the steering LOCK position, the fuel cap, and the seat or pillion lock for your model. No programming is involved, because the factory manuals show no immobilizer on any XB.

If the ignition switch has been replaced at some point with one that came with its own key, the fuel cap and seat may still be on the original cut. We check for that and can bring the locks back to a single key. Tell us if the steering is locked and how much fuel is in the bike, since you will not be able to add any until the key is made.

Where to find the key code

Buell's XB owner's manual tells you to record the key number in the space at the front of the book and says the number is impressed on a plastic tab that comes with the keys. Look for that tab on the original key ring and in the bike's paperwork. If it is gone, the key is made from the locks on the bike.

Buell XB Firebolt, Lightning and Ulysses key FAQ

Does the Buell XB gas cap use the ignition key?

Yes. The owner's manual has you lift the tab on the cap, insert the ignition key into the filler cap lock and turn it a quarter turn to release the cap.

Where is the steering lock on a Lightning XB12S?

In the ignition switch on the upper triple clamp. With the bars full left and the key in OFF, push the key in and turn it counterclockwise to LOCK.

How do I get the seat off a Ulysses without the key?

The seat lock takes the ignition key, so without one it stays on. We cut a key to the bike and the seat lock opens with it like the rest of the locks.

Do Buell XB keys have a transponder?

No. They are plain cut keys, and the XB manuals describe no immobilizer or security module from the factory.

I lost the plastic tab with the key number. Does that matter?

It makes ordering a key by code harder, but it does not stop a key being made. We work from the locks on the bike.
