> The Z900RS is one of the few US Kawasakis where you should expect a chip key. The 2018 US owner's manual describes an immobilizer with keys registered to the bike, and Kawasaki's US catalog names the blank as an immobilizer blank. The 2019 and 2020 manuals drop that content, so we confirm from your key and VIN. The Z650RS is listed with a plain blank, its 2022 US manual has no immobilizer section, and it is a straightforward cut-key bike.

**Kawasaki Z900RS and Z650RS key quick facts**

- Kawasaki's 2018 US Z900RS manual tells owners to make sure their ignition keys are registered by the immobilizer system and to have a dealer register extra keys.
- On that bike a red indicator blinks after the ignition is switched off to show the immobilizer is working, and stops after 24 hours.
- The US catalog lists the Z900RS blank, 27008-0558, as an immobilizer key blank for both the 2018 Z900RS and the 2020 Z900RS Cafe.
- The 2019 US Z900RS Cafe manual and the 2020 US manual for the Z900RS and Cafe have no immobilizer content; the 2020 manual shows a plain red warning indicator.
- The 2022 Z650RS ABS is listed with plain blank 27008-0662 and separate helmet, seat and fuel cap locks.

## Kawasaki Z900RS and Z650RS key types by year

| Years | Models | Key type | Chip | Notes |
| --- | --- | --- | --- | --- |
| 2018 | Z900RS, Z900RS Cafe | transponder key | yes | The US manual describes an immobilizer warning indicator and registered keys. The catalog lists two ignition switch part numbers for 2018. |
| 2019 onward | Z900RS, Z900RS Cafe, Z900RS SE | cut key on the same immobilizer-type blank | varies | The 2019 and 2020 US manuals have no immobilizer section, but the catalog still lists the immobilizer blank. A key photo and the VIN tell us which applies. |
| 2022 onward | Z650RS, Z650RS ABS | mechanical cut key | no | Plain blank in the 2022 US catalog, the same number used on the Z500 and Ninja 500. No immobilizer section in the 2022 US manual. |

## The Z900RS immobilizer, in Kawasaki's words

Most US Kawasakis leave the immobilizer out. The 2018 Z900RS manual, written for the US model, puts it in. Its indicator table names a combined warning and immobilizer light, and explains that the light blinks if an improperly coded key is used or if the antenna and key fail to communicate. The troubleshooting pages add a tip: a spare key or other metal hung on the same ring can interfere, so try the key on its own before assuming a fault.

The 2019 Cafe manual has no immobilizer text, and the 2020 manual, covering the Z900RS and the Cafe, reads differently from the 2018 one. The same light is called a red warning indicator and the registration advice is gone. Kawasaki's catalog, though, lists one blank for both years and calls it an immobilizer blank. We treat every Z900RS as possibly coded until the key and VIN show otherwise.

**Need a key for your Z900RS?** Call or text with the year and where the bike is parked. Call or text (619) 775-1858.

## What that means when a key is lost

If the bike has the immobilizer and you still hold one working key, adding another is a matter of cutting it and registering it. The 2018 manual directs owners to a Kawasaki dealer for registration, and we can tell you when you call whether we can program your year on site.

With every coded key gone, the job is bigger. Kawasaki's service literature for its transponder system says the ECU and ignition switch are replaced when no registered key remains. Before you commit to that, call us with the VIN. If your bike turns out to be a plain-key version, a new key is cut to the locks and you are done.

## Locks on the RS models

Both retro models hide the seat lock under a small cover.

- Z900RS seat: remove the seat lock cover, insert the ignition key, and lift the rear of the seat while turning the key clockwise.
- Z900RS: the tool kit is under that one-piece seat.
- Helmet lock: Kawasaki's catalog lists a helmet lock assembly for the Z900RS and the Cafe. On the Z650RS it is on the left side and opens with the ignition key turned clockwise.
- Fuel cap: opened with the ignition key; Kawasaki notes the key cannot be removed unless the cap is locked properly.
- Z650RS: Kawasaki lists the fuel cap lock, seat lock and helmet lock as three separate assemblies that share the key.

## Z650RS: the simple one

The Z650RS follows the Z650 and the 500 twins. Kawasaki's catalog gives it an ordinary blank and no coded-key parts. Lose the key and we cut another from the lock after checking your photo ID and the registration or title. We test the new key in the helmet lock as well as the seat and fuel cap.

## Where to find the key code

Both Z900RS manuals show the ignition key with a key number tag and say the key number or a spare key is needed for a duplicate. If all keys and the number are lost, Kawasaki's stated remedy is a new ignition switch and locks.

## 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)

## Kawasaki Z900RS and Z650RS key FAQ

### Does the Z900RS have a chip key in the US?

The 2018 US manual says yes: it describes an immobilizer and keys registered to the bike. The 2020 US manual does not. Kawasaki lists the same immobilizer-type blank for both, so we confirm from your key and VIN before quoting.

### My Z900RS warning light blinks after I turn the bike off. Is something wrong?

On a 2018 bike that is normal. The manual says the red indicator blinks to show the immobilizer is active, stops after 24 hours, and the blinking can be turned off.

### The engine will not start and the red light is flashing with the key on. What should I check?

Kawasaki's manual suggests removing any other keys or metal items from the key ring and trying again, since they can block communication between the key and the bike. If it still flashes, the key may not be registered.

### Is the Z650RS key coded?

Kawasaki's US parts catalog lists a plain key blank for the 2022 Z650RS ABS, the same one used on its plain-key 500s.
