Each one borrows its key blank from a sibling: the Z650 from the Ninja 650 and Z900, the Z400 from the Z650 at first and the current 500s from 2023, and the Z125 Pro from Kawasaki's small dual-sports. A lost key on any of them is cut at the bike and needs no programming. **Kawasaki Z125 Pro, Z400 and Z650 key quick facts** - Kawasaki's US catalog lists blank 27008-0596 for the 2017 Z650 ABS, the same number it lists for the 2017 Ninja 650 and Z900. - The Z400 ABS takes blank 27008-0596 in the 2021 and 2022 catalogs. From 2023 it takes 27008-0662 and the same ignition switch part number as the 2024 Ninja 500 and Z500. - The Z125 Pro changed blanks: 27008-0559 in the 2017 and 2019 catalogs, then 27008-0650 from 2020. - The US owner's manuals for the 2018 Z650, the 2023 Z400 and the 2017 and 2023 Z125 Pro have no immobilizer section. - On the Z650 the key releases the passenger seat first, and the rider seat comes off after it. ## Kawasaki Z125 Pro, Z400 and Z650 key types by year | Years | Models | Key type | Chip | Notes | | --- | --- | --- | --- | --- | | 2017 onward | Z125 Pro | mechanical cut key | no | Blank 27008-0559 in the 2017 and 2019 catalogs, the number also listed for the 2015 KLR650. Blank 27008-0650 in the 2020 to 2023 catalogs, shared with the 2020 KLX230, with a seat lock and a fuel cap lock rotor. | | 2019 onward | Z400, Z400 ABS | mechanical cut key | no | Blank 27008-0596 in the 2021 and 2022 catalogs, then 27008-0662 in the 2023 and 2024 catalogs, with seat and fuel cap locks; a helmet lock is an accessory. No immobilizer section in the 2019 or 2023 US manual. | | 2017 onward | Z650, Z650 ABS | mechanical cut key | no | Blank 27008-0596 and a single seat lock in the 2017 and 2020 catalogs. No immobilizer section in the 2018 US manual. | ## Three naked bikes, three borrowed blanks None of these models has a key of its own. Kawasaki reuses blanks across platforms, and the catalog makes the family ties clear. The Z650 shares its blank and its seat lock part number with the Ninja 650 it is built from. The Z400 started on the Z650's blank and moved to the one used by the newer 500 twins for 2023. The Z125 Pro, a 125 cc mini, sits with the KLR650 and KLX230 in the blank listings. The practical point is that all three are ordinary keys. Suppliers sell transponder keys for versions of the Z650 built for other markets, and those listings cause confusion online. A bike sold new in the US takes the plain blank. **Need a key for your Z125 Pro?** Call or text with the year and where the bike is parked. Call or text (619) 775-1858. ## Locks the key works Naked bikes carry fewer locks than faired ones, and what you get varies by model. - Z650: ignition and steering lock, fuel cap, and one seat lock that frees the passenger seat. Kawasaki also catalogs accessory panniers, a top case bracket and a U-lock bracket for it. - Z400: ignition and steering lock, fuel cap lock and seat lock, with helmet hooks under the seat. A keyed helmet lock exists as a Kawasaki accessory, so some bikes have one and some do not. - Z125 Pro: ignition and steering lock, a seat lock and the fuel cap, which has a key hole cover. - Accessory luggage on a Z650 may use a different key from the bike. ## Key trouble to plan for The Z125 Pro is small and light, so a theft attempt is worth planning for. A screwdriver forced into the ignition leaves the switch damaged even if the bike was not taken, and afterwards the proper key may no longer turn. That is an ignition repair or replacement, and the new switch can be keyed to match your fuel cap and seat. On a Z400 or Z650 the avoidable problem is a single key that goes missing with no spare ever made. If you bought yours used with one key, getting a second cut while the first still exists costs far less than starting from no key. ## Getting back on the road with no key We come to the bike, confirm that you own it using your photo ID and the registration or title, and make a key from the lock. On a Z650 or Z400 we then check it in the fuel cap and under-seat lock. On a Z125 Pro there are only the seat lock and fuel cap to check. Kawasaki's Z650 manual gives the factory alternative: without a key or the key number, replace the ignition switch and every lock that shares the key. Cutting to the existing locks leaves the bike original and costs less in parts. ## Where to find the key code The Z650 manual shows the ignition key with a key number tag and says the key number or a spare key is needed to have a duplicate made. Check the paperwork from the selling dealer for the tag. ## 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 Z125 Pro, Z400 and Z650 key FAQ ### Does the Z650 have a chip key in the US? No. The 2018 US owner's manual has no immobilizer section, and Kawasaki's US catalog lists the same plain blank used on the Ninja 650 and Z900. ### Can a Z125 Pro key be made without the original? Yes. It is a plain cut key, so we make one from the ignition lock on site once ownership is confirmed. ### Is a Z400 key the same as a Ninja 400 key? The two bikes share a platform and both use plain keys. The blank has to match the lock that is on your bike, so send a photo of the key or the ignition and we will bring the right one. ### Someone tried to steal my Z125 and now the key will not turn. Is that a key problem? Usually not. A forced ignition is damaged inside, so a new key alone will not fix it. We repair or replace the switch and key it to the rest of the bike. ## The immobilizer system on this bike - [Kawasaki Immobilizer and KIPASS: Keys, Fobs and Lost Keys](https://themotorcyclelocksmith.com/san-diego/immobilizer-systems/kawasaki-immobilizer-kipass/): Kawasaki has two electronic key systems: a transponder immobilizer with coded keys, and KIPASS, a fob system used on the Concours 14 and a few newer models. ## More Kawasaki models [Concours 14](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/concours-14/), [KLR650 and KLR250](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/klr650/), [KLX230, KLX250 and KLX300](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/klx230-klx250-klx300/), [Ninja 1000, Z1000 and Z800](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-1000-z1000-z800/), [Ninja 300 and Versys-X 300](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-300-versys-x-300/), [Ninja 400 and Ninja 250R](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-400-ninja-250r/), [Ninja 500, Z500 and Eliminator](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-500-z500-eliminator/), [Ninja 500R and Ninja 250 (EX250F)](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-500r-ninja-250-ex250f/), [Ninja 650 and Z900](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-650-z900/), [Ninja 650R and ER-6n](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-650r-er-6n/), [Ninja H2, H2 SX and Z H2](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-h2-h2-sx-z-h2/), [Ninja ZX-10R](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-zx-10r/), [Ninja ZX-11](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-zx-11/), [Ninja ZX-14 and ZX-14R](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-zx-14r/), [Ninja ZX-6R and ZX-4R](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-zx-6r-zx-4r/), [Ninja ZX-7R, ZX-9R and ZX-12R](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/ninja-zx-7r-zx-9r-zx-12r/), [Versys 650 and Versys 1000](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/versys-650-versys-1000/), [Vulcan 1500, 1600 and 2000](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/vulcan-1500-1600-2000/), [Vulcan 1700](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/vulcan-1700/), [Vulcan 500 LTD, 750 and 800](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/vulcan-500-750-800/), [Vulcan 900](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/vulcan-900/), [Vulcan S](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/vulcan-s/), [W800 and W650](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/w800-w650/), [Z900RS and Z650RS](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/z650rs-z900rs/), [ZRX1200R, ZZR1200 and Concours](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/zrx1200r-zzr1200-concours/), [All Kawasaki keys](https://themotorcyclelocksmith.com/san-diego/makes/kawasaki/) ## Services for this bike - [Lost Motorcycle Key, No Spare](https://themotorcyclelocksmith.com/san-diego/services/lost-motorcycle-key/): No key at all?
