> The modern Katana, model code GSX-S1000S, comes with a pair of identical ignition keys. Suzuki's owner's manual for it describes an immobilizer on the equipped model and labels the dash indicator as fitted if equipped, so the first job after a lost key is working out which version you have. Send us the VIN and tell us what the dash does at switch-on, and we will tell you what the visit involves.

**Suzuki Katana (2020 on) key quick facts**

- Suzuki's Katana owner's manual says the bike comes with a pair of identical ignition keys.
- On the immobilizer equipped model the manual says two keys are registered from new and a dealer can add two more.
- The same manual says that if all keys are lost on an equipped bike, the ECM should be replaced.
- The seat is one piece. Its lock sits under the left frame cover and the ignition key turns clockwise to free it.
- Helmet holders, luggage straps and the tool kit are all under or on the bottom of that seat.
- The manual's fuse list names the immobilizer as if equipped, so not every Katana has one.

## Suzuki Katana (2020 on) key types by year

| Years | Models | Key type | Chip | Notes |
| --- | --- | --- | --- | --- |
| 2020 on | Katana (GSX-S1000S) | cut key, carrying a transponder on immobilizer equipped bikes | varies | The owner's manual prints two ignition switch drawings, one marked for the immobilizer equipped model, and lists the indicator light as if equipped. Confirm from the dash and the VIN. |

## Chip key or plain key on a Katana

Suzuki writes one Katana manual for several markets and marks the parts that only apply to some bikes. The key page says the bike has a pair of identical keys, then adds a note for the immobilizer equipped model: the identification code is programmed into the key, so a copy cut by an ordinary locksmith will not start the engine. That sentence is about a key that has only been cut. It does not describe a key that has also been registered to the bike.

On an equipped Katana the immobilizer indicator blinks twice when you turn the switch on, stays lit for about 2 seconds and goes out. The manual also says the light blinks the number of registered keys, so two blinks is what a bike with its two original keys shows. If the light keeps blinking, the manual calls that a communication error between key and ECM or the wrong key, and the engine will not start until it is sorted out.

## What the one key opens

There is no separate helmet lock key. The helmet holders are under the seat, so you take the seat off, hook the helmet on and refit the seat. The folded luggage straps live under there too, and the tool kit is strapped to the bottom of the seat itself.

- Ignition switch with four positions: OFF, ON, LOCK and P for parking
- Steering lock, built into the switch: bars fully left, push the key down, turn to LOCK
- P position: steering locked with the taillight left on for roadside parking at night
- Fuel tank cap: key in, turn clockwise, lift the cap with the key still in it
- Seat lock under the left frame cover: turn clockwise, raise the rear of the seat and slide it back

## Habits the manual warns about

Suzuki puts a warning on the key page that a long key chain could get caught between the ignition switch and the upper bracket and interfere with steering. It tells you to use the key without chains or other keys attached, and says a hard key holder can damage the plated and painted parts around the switch.

For equipped bikes there is a second list. Keep other immobilizer keys away from the switch, including the Katana's own spare. Do not hang anything metal, magnetized or radio transmitting on the key holder, because it affects the communication between key and bike. And if a key goes missing, the manual says to ask a dealer to have the lost one deactivated.

## When every Katana key is gone

The manual's own answer for an equipped bike is blunt: the ECM should be replaced. That is the dealer route, and it means moving a bike that will not start. Before you commit to it, call us with the VIN. We check your photo ID against the registration or title, establish whether your Katana is equipped, cut a key to the locks where the bike is parked, and tell you up front whether registering that key on site is possible for your bike.

With one working key still in hand the job is simpler. A spare on an equipped bike is cut and then registered, and the bike has room for it as long as fewer than four keys are on the system.

## Where to find the key code

Suzuki's Katana owner's manual does not describe a key number plate or a place to record a key code; it only says the bike comes with a pair of identical keys. If your keys came with a small stamped tag, keep it with the spare, away from the bike.

## What to have ready

**Have this ready when you call or text**

- Year, make and model of the bike
- Where the bike is parked
- Whether you have any working key, a broken key or a key code
- Photo ID and registration or title (we verify ownership before making a key)

## Suzuki Katana (2020 on) key FAQ

### Is the 2020 on Katana the same as the old Katana 600 and 750?

No. The modern Katana is the GSX-S1000S, a different motorcycle from the GSX600F and GSX750F Katanas of the 1990s and 2000s. This page is about the modern one.

### How many keys can a Katana have?

On the immobilizer equipped model, Suzuki's manual says two are registered at the factory and two more can be added, so four in total.

### My Katana's key light keeps blinking and it will not crank. What now?

The manual says to turn the ignition off and on again so the key and ECM can communicate properly. Take other chip keys and metal fobs off the ring first. If it still blinks with a key that used to work, the key or the system needs looking at.

### Can I get under the Katana seat without the key?

The seat is held by a key lock under the left frame cover, so no key means a locksmith visit. Once a key is cut it works that lock along with the ignition and fuel cap.

## The immobilizer system on this bike

- [Suzuki Immobilizer (SAIS): Chip Keys, Lost Keys and US Models](https://themotorcyclelocksmith.com/san-diego/immobilizer-systems/suzuki-immobilizer/): Suzuki's immobilizer, which Suzuki calls the Suzuki Advanced Immobilizer System, stores an identification code in the key and will not let the engine start without it.
