CFMOTO 675SS and 800NK Key Replacement

Quick answerCFMOTO's three-cylinder 675SS and twin-cylinder 800NK both use a conventional cut key. Their North American owner's manuals describe a keyed ignition with a handlebar lock, a keyed fuel tank lock and a keyed seat lock, and neither manual has an immobilizer or key programming section. A lost key is made at the bike by cutting a new one to the locks.

CFMOTO 675SS and 800NK key quick facts

The 675SS owner's manual (model CF650-10US) describes an ignition lock with three key positions: handlebar lock, stop and start.
The 800NK owner's manual (model CF800-7US) lists the same three positions on its ignition switch.
On both bikes the fuel tank lock sits under a cover or press plate and is released with the ignition key.
The seat lock is on the left side of the vehicle on both models; on the 675SS it releases the passenger seat.
On the 675SS the rider's seat comes off only after the passenger seat, and the battery is underneath.
The 675SS manual warns that the ignition key may break if overloaded in the fuel tank lock and must then be replaced.

CFMOTO 675SS and 800NK key types by year

Years	Models	Key type	Chip	Notes
From 2025	675SS	cut key	no	Ignition and handlebar lock, fuel tank lock and passenger seat lock on one key. No immobilizer section in the owner's manual.

Big screens, simple keys

Both of these bikes have color dashes, ride modes and phone connectivity, so owners reasonably assume the key is electronic too. The manuals say otherwise. Under the heading for locks, each one shows a key-operated ignition with a position that locks the handlebar, a position that switches everything off and a position that powers the bike and allows a start. The fuel tank and the seat have their own keyholes for the same key.

The 675SS manual does mention an anti-theft alarm among the reasons the turn signals may flash, and it covers CFMOTO's app and telematics module for select markets. Those are alert features. Nothing in either manual describes the key being checked electronically before the engine will run.

Handlebar lock, tank and seat in detail

The 675SS manual adds a line worth taking seriously: do not leave keys on the vehicle, and lock the steering before walking away.

675SS handlebar lock: switch off, turn the handlebar to the left end, press the key down and turn it left to the lock mark, then remove it
800NK handlebar lock: turn the handlebar left to the maximum and lock the steering with the key
675SS fuel tank: flip up the press plate, insert the key and rotate it clockwise, open the cap; press the cap down until it locks, then take the key out
800NK fuel tank: open the lock cover, insert the key and turn to release
Seat lock: left side of the bike, insert the key and turn to release

Why the seat lock matters on the 675SS

CFMOTO's battery removal steps for the 675SS start with the key. You release the passenger seat at the seat lock, pull back the tail of the front seat to reach its mounting bolts, and only then get to the battery. If the key is lost and the battery is flat, the two problems stack up, since the jump or charge point is behind a lock you cannot open.

The manual also says the hexagon key from the tool kit can be stored under the rear seat. Keep that in mind before assuming you can do a roadside fix without the key.

All keys lost on a 675SS or 800NK

We ask for photo ID and the registration or title, then make a key to the bike's locks and test it in the ignition, the handlebar lock position, the fuel tank lock and the seat lock. There is no programming step on these models.

These are recent models. A key cut to fit the original locks leaves those locks unchanged. If any lock was damaged trying to get in, tell us when you call so we can plan to repair it during the visit.

Where to find the key code

The 675SS and 800NK owner's manuals do not describe a key code tag or a place to write a key number. Check the original keys and the dealer delivery paperwork for a stamped or printed number. Without one, the key is made from the locks on the motorcycle.

CFMOTO 675SS and 800NK key FAQ

Does the CFMOTO 675SS have an immobilizer chip in the key?

The 675SS owner's manual describes a cut key for the ignition and handlebar lock, fuel tank lock and seat lock, and has no immobilizer or key programming section.

Is the 800NK keyless like the Ibex 800?

The 800NK owner's manual shows a key-operated ignition switch with handlebar lock, stop and start positions. Keyless start is described for some Ibex 800 versions, which are a different model.

My key bent in the 675SS fuel cap. Is it safe to keep using?

No. CFMOTO's manual notes the key may break if overloaded there and says a broken key must be replaced. Have a new key cut from the bent one before it snaps in a lock.

Can I get to the 675SS battery without the key?

Not by the method in the manual, which begins by releasing the passenger seat with the key at the seat lock. A locksmith can open the seat lock and make a key at the same visit.
