What it means
Typical causes are using an unregistered or non-transponder (blank) key, or a faulty key transponder. Kawasaki shows this on models fitted with the immobilizer (chip-key) anti-theft system, via the FI/service-code display. The engine will not start until the fault is resolved. Note: code numbers can vary by model — confirm against your manual. Once the fault is resolved the code clears; key/component registration requires a Kawasaki diagnostic tool and the registration procedure.
Symptoms
- Engine won’t start
- Service code 36
- Often when using a spare/new key

Frequently asked questions
I cut a spare key and got code 36 — why?
A mechanically-cut spare with no programmed transponder reads as "blank". It must be registered to your bike’s immobilizer before it will start the engine.
