Quick answerThe Ninja ZX-11 is a 1990s Kawasaki with a 1990s key: plain cut metal, no chip. Kawasaki's US parts diagrams for the bike list an ignition switch, a set of small body locks and a single key blank, with no immobilizer components. If yours has no key, one can be cut to the locks where the bike sits.

  • The D-model diagram lists four separate lock assemblies besides the ignition: seat, seat striker, helmet and tool box.

What Kawasaki's parts catalog shows

Kawasaki's US parts diagrams for the ZX-11 show every keyed part the factory fitted. On the earlier C model the diagram is titled Ignition Switch. On the later D model it becomes Ignition Switch/Locks/Reflectors, and more locks appear in it.

In both, the key is listed as a lock key blank, a piece of uncut metal the dealer cuts to suit. Kawasaki's later immobilizer bikes show extra electronic parts around the switch. The ZX-11 diagrams show none, which fits a carbureted bike of its age.

The locks on a ZX-11

  • Ignition switch, listed as a single assembly on both generations
  • Fuel tank cap, with a replaceable lock rotor and a tank cap cover
  • Seat lock assembly, on both the C and D models
  • Helmet lock assembly, listed for the D model
  • Tool box lock assembly, listed for the D model
  • Seat striker lock assembly, listed for the D model

Old locks, mixed keys

A ZX-11 is old enough that its lock set may no longer be the one it left the factory with. The small body locks are listed individually in Kawasaki's catalog, so a replacement helmet lock or tool box lock fitted years ago may not match the ignition unless someone keyed it to suit. If you carry two keys for one bike, that is a likely reason.

It is also why we check every lock on the bike before cutting. If the locks no longer agree, we can make keys for each, or rekey the odd ones so a single key works everything again. Tell us which locks your current key does and does not open.

No keys at all

Bikes of this age often change hands as projects, sometimes with no key and thin paperwork. We need photo ID and a title or registration in your name before making a key. After that the job is mechanical: we work out the cuts from the bike's locks, cut the key and test it in the ignition, the fuel cap and the seat. If the bike has sat for years, a lock that will not turn even with a correct key may need cleaning or repair, and we will show you which one.

Where to find the key code

Kawasaki supplies a key number with new keys, on a tag or small plate. On a ZX-11 that has had several owners the number may be long gone. Ask the seller for any tag or spare; otherwise the key is cut from the lock itself.

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 Ninja ZX-11 key FAQ

Does the Ninja ZX-11 have an immobilizer?

Kawasaki's US parts diagrams for the ZX-11 list a plain key blank and no immobilizer parts. A correctly cut key is all it needs.

Do the C and D model ZX-11 use the same key blank?

Kawasaki's catalog lists different key blank part numbers for the 1990 C1 and for the 1999 and 2001 D models, so we go by your bike's locks, not just the model name.

My ZX-11 key opens the seat but not the helmet lock. Why?

The helmet lock is a separate assembly on the D model and is sold on its own, so it may have been replaced with one keyed differently. It can be rekeyed to match.

I bought a ZX-11 project with no key. What do you need from me?

Photo ID and a title or registration in your name. If the paperwork is still being sorted out, get that settled first; we can explain what is acceptable when you call.
