Suzuki V-Strom 800, GSX-8S and GSX-8R Key Replacement

Quick answerSuzuki's 776cc twins all use a conventional key in a four-position ignition switch with a lid over the keyhole. The V-Strom 800 manual carries an immobilizer section marked if equipped, while the GSX-8S and GSX-8R manual has no immobilizer text at all. Losing the key is fixable either way, and the dash tells us which job it is.

One engine family, two manuals

The V-Strom 800DE, the road-biased V-Strom 800, the naked GSX-8S and the faired GSX-8R are built around the same parallel twin. Suzuki documents them in two books: one for the two V-Stroms and one for the two GSX-8 models.

Both books show the same ignition switch with ON, OFF, LOCK and P positions and the same keyhole lid. The difference is in the immobilizer. The V-Strom book labels the switch for the immobilizer equipped model and explains the system under a heading that ends with if equipped. The GSX-8 book never uses the word. Suzuki builds these bikes with and without the system depending on where they are sold.

How the equipped version behaves

Suzuki's description is short. When the ignition is switched on, the bike's ECM asks the key for its ID, the key answers, and the ECM compares that ID with the ones registered to the motorcycle. If it matches, the engine can be started.

You can watch this happen. The immobilizer indicator blinks a number of times at switch-on, and Suzuki says the count is the number of keys registered to the bike. After a correct ID it stays lit for 2 seconds. Two blinks on a bike you bought with one key means a second registered key exists somewhere. A dash with no such indicator belongs to a plain-key bike.

Fuel cap, seats and helmet holders

Ignition: to release the steering lock, push the key in and turn it from LOCK to OFF. P leaves the position light, license plate light and taillight on with the steering locked.
Fuel cap: insert the key and turn it to the right. Suzuki notes the key cannot be removed if the cap is not locked.
GSX-8S and GSX-8R rear seat: ignition key in the seat lock, turned clockwise.
Helmet holders on the GSX-8 models are underneath the rear seat.
The rider's seat on the GSX-8 models comes off after the rear seat, by removing a bolt. It has no key lock of its own.
Suzuki lists a plastic side case set and a 35 litre top case for the V-Strom 800 as a one-key system that locks with the ignition key. Its other cases come with their own lock and key or need a separate lock set.

When the key is lost

The GSX-8 manual puts it plainly: damaging or losing these keys will cause you to incur significant expense. Much of that expense on a new bike is the tow and the wait. We come to the motorcycle, check your photo ID with the registration or title, and read the dash to see which version it is.

For a plain-key bike we cut a key to the locks and test it in the switch, the fuel cap and the seat lock. For an immobilizer equipped bike, registering a key takes extra equipment and time, and we tell you before the visit whether it can be done on site for your model year. If you still have one key, a spare made now is the cheaper visit.

Where to find the key code

The alphanumeric key number is printed on a plate that comes with the two keys, as the GSX-8S and GSX-8R manual notes in its serial number section. Photograph the plate and store it away from the bike.

Suzuki V-Strom 800, GSX-8S and GSX-8R key FAQ

Does the GSX-8S have an immobilizer?

It depends on the market version. The GSX-8S and GSX-8R owner's manual has no immobilizer text, while the related V-Strom 800 manual lists the system as if equipped. An indicator that blinks at switch-on means your bike has it.

What do the blinks of the V-Strom 800 immobilizer light mean?

Suzuki's manual says the number of blinks at switch-on is the number of keys registered to the motorcycle. The light then stays on for 2 seconds after a correct key ID.

Why can't I pull the key out of my GSX-8R fuel cap?

The manual says the key cannot be removed if the cap is not locked. Close the cap fully and the key should release. If it still will not, do not force it.

Is the GSX-8R key the same type as the GSX-8S key?

Yes. Both models are covered by one owner's manual with one ignition switch and key number section.
